Navigate the Cisco Crosswork Situation Manager UI

The Cisco Crosswork Situation Manager UI is split into several key components including the top bar, workbench summary and side menu. The sections below give a brief overview and description of these components. Click any of the links on this page for more information.

A. Workbench : The Workbench is the default landing page and working area where you will spend most of your time.

B. Search Bar - Allows you to perform a contextual search for a specific alert or Situation or both alerts and Situations.

C. Help & Support - Provides links for help, tutorials and support information such as your version number, database schema and upgrade history.

D. Notifications - Displays notifications about invitations and assignments. See Notifications for more information.

E. User Menu - The User Menu is where you can perform a number of user-related actions such as changing personal details and customizing Cisco Crosswork Situation Manager. Your administrator can reset your password if you forget it.

F. Dashboards - Dashboards are screens comprising of a series of widgets which offer overviews and statistics for different aspects of Cisco Crosswork Situation Manager.

G. Workbench Summary - Displays an overview of statistics for your system, for your teams and for your Services.

H. Team Rooms - Links to the Team Room(s) for your team(s).

I. Services Impacted - Displays all services monitored by your team which are impacted by Situations. Services Impacted updates every minute. The Situations and alerts counts update in real time.

J. Situation and Alert Views - Displays Situations and alerts which are assigned to you under My Situations and My Alerts, as well all unresolved Situations and Alert under Open Situations and Open Alerts.

K. Maintenance Schedule - Schedules maintenance windows if you want to reduce noise so do not want new Situations being created.

Summary Overviews

The System Overview offers a high-level overview of the key statistics for your Cisco Crosswork Situation Manager system such as the noise reduction and the number of Events, Alerts or Situations over the past week. These statistics are automatically updated every five minutes. It also displays the mean time to acknowledge (MTTA) in minutes and the mean time to resolve (MTTR) over the past week.

The Team Rooms displays an overview for your team and includes statistics about the number of impacted Services, situations assigned to the team, the MTTA and MTTR in minutes. These statistics are automatically updated every five minutes.

The Services Overview displays the latest impacted Services and the number of hours or days the Services have been affected. The color of each Service panel indicates the highest severity of the Situations impacting it.

Impacted For and Open Situation statistics update every minute. MTTA and MTTR automatically update every hour.

Search Bar

You can use the search bar in the top bar to quickly find alerts or Situations you are interested in.

Once a search has been made, you can narrow down the search results to pinpoint exactly what you are looking for.

Enter any alphanumeric text into the search bar, such a Situation ID number or a Service name, and then hit Enter to continue.

The search results appear in new screen, showing all successful results relating to both Situations and alerts by default. Search results appear in the order in which they occurred: oldest to most recent in descending order.

You can narrow the search results using the field options on the right side of the screen:

Results generated from the search bar are static. For example, a search for Situations created within the last hour shows a static list of Situations created within one hour of when the search was carried out. As time progresses, this information becomes out of date. Therefore, to show Situations created within one hour of the present time, carry out the search again to get new results.

Cisco Crosswork Situation Manager Notifications

Notifications keep you informed of your invitations, assignments and any critical Situations in Cisco Crosswork Situation Manager.

You can subscribe to receive Situation notifications about invitations, assignments, critical Situations assigned to your team.

Situation Severity

There are six default industry-standard severity levels, which are shown and described below:

·         Clear: Indicates that one or more Events have been reported but then subsequently cleared either manually or automatically.

·         Indeterminate: Indicates the severity level could not be determined.

·         Warning: Indicates that a number of potential or imminent service affecting faults have been detected.

·         Minor: Indicates there is a non-service affecting fault but action could be required to prevent it becoming a more serious issue.

·         Major: Indicates a service affecting fault has developed and corrective action is urgently required.

·         Critical: Indicates that a serious service affecting fault has occurred and corrective action is required immediately.

The color severity of the My Situations and Open Situations icons on the Side Menu indicates the highest severity level of the alerts within each list. A Situation's severity will be determined by its alert with the highest severity level. If this alert is cleared then the Situation adopts the severity level of the alert with the next highest severity.

·         Click Done.

Alert Workflow

Administrators can assign alerts to different Cisco Crosswork Situation Manager users, own alerts and add them to Situations.

The standard method of working with alerts is to have an Administrator who assigns alerts to the Users within a team. An alternative is to have a single Administrator who owns Situations and deals with all of their associated alerts. The sections below outline the standard workflow that can be applied to both of these methods.

Assigned Alerts

Once an alert has been assigned to you, you will either receive a Notification or it will appear in your My Alerts filter.

After identifying which alerts have the highest priority, typically the alerts with the highest severity, the next step is to Acknowledge them to let others know that you are aware of them. A standard way of working would be to work through all of the day's 'Critical' alerts and resolve those first before working on the days 'Major' and then 'Warning' alerts to prevent them becoming 'Critical' alerts.

To do this, right click in the alert's row or tag it using the checkbox in the far left column and then click Tools > Acknowledge.

Timeline

To access an alert's timeline, right click on it and select Show Timeline.

The timeline shows a graphical view of an alert and a breakdown of the events that were de-duplicated to create the alert. It also displays the severity of each event and the times at which they occurred.

Click the Zoom In or Zoom Out options to focus in on a particular time period or group of events. Alternatively use the blue sliders to focus in on an area of interest. The severity of each event is indicated by the color of the line. For example, the events in the screenshot above are a mixture of indeterminate and critical Events.

The alert's severity is defined by the severity of the latest event rather than the event with the highest severity.

Click any of the colored lines for more information on any event in the timeline. This will open the Event Details window. The Events Details window allows you to explore the forensic details of an event or events.

The individual column names and their descriptions are listed below:

Collaborate

Go to Collaborate in the Situation Room and share comments or ideas with your colleagues to find a resolution.

Ultimately, the aim is to resolve high severity alerts before you resolve the Situation. If anyone proposes a solution, this can be tested using Tools or going back to the My Alerts view and clicking on the Host column to SSH into it.

Resolving Steps

If you or another user finds a solution that fixes the problem, the comment should be marked as the Resolving Step. To do this, click the check icon next to the post in Comments or under Collaborate:

The comment which has been marked as the Resolving Step will be highlighted with a green line. Now a resolution has been found, this Situation can be resolved.

To do this click on the Resolve button under Status in the Situation Room. The 'Resolve Situation' pop-up window will appear:

Add a star rating to indicate the relevance and quality of information given in the Situation along with a journal entry comment. Click Done to continue.

Assign and Acknowledge Situations

After Cisco Crosswork Situation Manager creates and opens a Situation, the next steps are:

·         A user goes to the Situation Room and assigns the Situation.

·         The assigned user acknowledges the Situation.

Assign to a User

To assign to a user, go to the Situation Room, click Assign, and choose the relevant user.

Team Assignment

The Team Room shows all Situations assigned to that team. Cisco Crosswork Situation Manager assigns each situation to teams automatically based on the current Service Filters and Situation Filters defined for each team. Note the following:

·         If a team has no Service or Situation filters defined, Cisco Crosswork Situation Manager assigns all open Situations to that team.

·         If a team has both Service and Situation filters defined, Cisco Crosswork Situation Manager assigns a Situation only if the team has both a matching Service Filter and a matching Situation Filter.

·         You can manually override the default team assignments for a specific Situation. Go to the Situation Room and click Teams.

·         If you override the team assignment for a Situation, automatic team assignment is permanently disabled for that situation.

·         If you unassign a Situation from your team, based upon your role, you might be unable to access the Situation afterwards.

Acknowledge an Assigned Situation

You should receive a Notification when you are assigned to a Situation. You need to acknowledge the assignment before you investigate and resolve it. Go to the Situation Room and click Acknowledge.

Change a Situation Assignment

Go to the Situation Room and click More Actions. You can:

·         Own: Re-assign to your self and acknowledge.

·         De-Assign: Set status to Open.

·         De-Acknowledge: Available only if the Situation is assigned to you and you have acknowledged the current assignment.

For information about other actions, see Take Additional Actions.

Work with Situations

After Cisco Crosswork Situation Manager creates Situations from the alerts ingested from your monitoring systems, you can use various tools to resolve them. When you resolve the Situation, you can provide feedback to help with the resolution of similar Situations that arise.

This topic guides you through the various steps in the workflow to resolve Situations.

How to Resolve Situations

The following workflow represents the typical steps to resolve a Situation. You may not need to execute every step for every Situation. As you become more experienced with Cisco Crosswork Situation Manager you may develop your own workflow to suit your requirements.

•      Check for Impacted Services in the Services Overview. In the Cisco Crosswork Situation Manager workbench, the Services Overview section indicates which of your Services are impacted by Situations.

•      Click on the Team Room name in the Side Menu to open your Team Room. The Team room is a good place to collaborate with the colleagues in your Team to find a resolution to your Situations. Click the Team Room name in the Side Menu. The Team Room displays all recent activity such as Situations being assigned, new comments that have been posted and any Resolving Steps that have been created. You can also see which members of your Team are currently logged into Cisco Crosswork Situation Manager on the right side of the screen.

•      Click the Task Board tab to view Situations in a Kanban-style board You can see which Situations have been assigned to you in the "Assigned" column.

•      Click Acknowledge on any Situation that has been assigned to you. This changes the status to "In Progress" and alerts your team to the fact that you are working on a situation.

•      Click on your assigned Situation. The Situation Room opens to display key information about the Situation including:

—      The Situation status.

—      The number of alerts.

—      Impacted services.

—      Next steps to resolve the Situation.

Resolve Situations

A Resolving Step is the comment, suggestion or action in the Collaborate section of a Situation Room or Team Room that has been marked as the solution to a Situation.

If a Situation has a Resolving Step, it is indicated by a check icon next to the Situation ID, as shown in the screenshot below:

Mark a Resolving Step

If you find a comment or suggestion has helped to resolve the root cause of the Situation then you should mark it as a Resolving Step. To do this, click the gray check icon in the top right corner of the comment:

When a comment has been marked as a Resolving Step, a green line appears along the top of the comment to highlight it. It is also pinned under the Next Steps in the Situation Room.

Multiple comments can be marked as the Resolving Steps. It does not have to be a single comment or action. Other users can subsequently approve or disapprove of the Resolving Step using the upvote and downvote icons. The number next to each icon will indicate the number of votes it has had.

Unmark a Resolving Step

A comment that has been made a Resolving Step can be unmarked at any point. To do this, click the check icon on the comment under Next Steps or Collaborate. This action appears on the Collaborate wall in the Team Room.

Resolve a Situation

A Situation can be resolved once a Resolving Step has been found.

To do this, click Resolve under Status in the Situation Room or change its status on the Team Room Task Board. The 'Resolve Situation' pop-up window then appears:

If Cisco Crosswork Situation Manager warns you that you have unmarked PRC alerts, click the Mark Alerts button to return to the Alerts list and mark the appropriate alerts. Click the stars to give it a star rating out of five to indicate the relevance and quality of information given in the Situation along with a journal entry comment.

It is important to reflect an accurate rating, particularly if you are using the Feedback Sigaliser which takes information such as Situation ratings into account. When you have entered your rating and journal entry, click Done to continue.

Rate a Situation

You can give ratings directly from the Situation Room or when resolving or closing a Situation from any Situation filter or from the Task Board.

When you resolve a Situation from either a filter or the Task Board, the 'Resolve Situation' pop-up window appears. You can rate the relevance and quality of the information given in a Situation each time you resolve one by giving it a star rating between 1 and 5. Each Situation rating is always followed by a journal entry or comment, where you can provide any additional information.

Click on the appropriate star rating depending on how relevant or accurate the Situation was. It is important to reflect an accurate rating, particularly if you are using the Feedback Sigaliser which takes information such as Situation ratings into account. For example, the default rating threshold for Feedback Sigaliser is 3 so it learns from any Situations with a rating of 3 stars or more.

The Situation rating scores are:

Next type in the 'Journal Entry' box to provide a comment about why the Situation was resolved or closed and a description of the resolution (if applicable). This can be as long as required. When you have finished writing the entry, click Done to continue.

Check Impacted Services

To prioritize which Situations to deal with first, check for impacted services with the highest severity. Typically you should deal with services impacted by critical Situations first. You can check for impacted services in Cisco Crosswork Situation Manager in three different ways: in the Services Overview, by creating a filter, and in the Services Impacted menu.

Services Overview

The Services Overview section displays any Services which are assigned to your Team or which are impacted by Situations assigned to your Team.

To assign Services to your Team, go to System Settings > Security > Teams and add the required Services to your Service Filter.

Each Service panel also includes the amount of time it has been impacted for, the number of open Situations which are impacting it, and the MTTA and the MTTR in minutes.

The color of the Service indicates the highest severity level of the Situations that are impacting it.

This panel automatically updates every minute by default. Click the text alongside 'Last Updated' for the exact time the update occurred.

Service Filter

Click any Service for more information about the impacting Situations. These Situations are displayed in a Situation filter, allowing you to identify those which you want to prioritize. For example, those with the highest severity or the number of high severity alerts.

You can see which other Services each Situation is impacting by referring to the 'Services Impacted' column.

Services Impacted

A list of all Services that have been impacted will appear in the Side Menu on the left side of the Workbench.

Click any of the Service names to view the Situations that are impacting it. Alternatively click Services Impacted to view all Situations that are impacting your Services in a Situation Filter.

The Services Impacted link from the Side Menu will open all Situations which are impacting your system's services in a new Situation Filter:

This screen offers a useful overview of the Situations which are affecting the most of your Services and can help you identify and prioritize which Situations to deal with first. It also allows you to see the Situations with impacting Services which are not associated with your team.

Work in a Team Room

The Team Room is the first place you should go for a general overview of the latest Situation activity in your team. This is where you can discuss issues with team members and collaborate to find a resolution to alerts and Situations.

There are two key components to the Team Room screen: Collaborate and Task Board.

Collaborate

The Collaborate tab is where you can view the latest activity and communicate with members of your team to find resolutions to Situations.

You can post questions, ideas, general comments and attach files so that they appear on the Collaborate news feed in chronological order.

Task Board

The Task Board is a Kanban-style board where you can see an overview of the team's Situations, where they are in the workflow, how much work is in progress and in the queue. A Kanban board is a visualization tool which can be used to see an overview of your workload and optimize the flow of your work.

This is a useful screen to see your assigned Situations and manage what work you and your team mates have to do. It is also where Administrators can assign Situations to different users.

Team Insights

Team Insights shows Situation summary data and Situation Severity data from two time frames: the last week and the last day.

Use the drop-down to choose from the last week or the last day. The default is the last week.

Highlight a line in a graph with your mouse pointer. Dots denote data points.

Cisco Crosswork Situation Manager collects data at a specific time in each 24 hour period and this may not reflect the highest number or severity of Situations during that period.

Navigation

The Situations appear in columns arranged in order of status: opened, assigned, in progress and resolved.

Each Situation appears with a colored pill-shaped marker displaying the Situation ID number, the severity color, the user who is assigned to the Situation, the time the Situation was created, the description, and the action that can be performed:

Task Board Flow

If you are a standard operator User, you can perform the following actions to Situations that have been assigned to you:

When resolving or closing a Situation, you can give it a Situation Rating and add a journal entry in the pop-up window as normal. Once a Situation is closed, it no longer appears on the board.

Collaborate in a Team Room

The Collaborate tab is where you can view the latest activity and communicate with members of your team to find resolutions to Situations.

Users can post questions, ideas, general comments and attach files that will appear on the Collaborate news feed in chronological order.

Navigation

The Situations listed on the right side of the screen are all of the Situations which are impacting services included in the team's service filter. The 'People' panel beneath that lists all team members who are currently logged into Cisco Crosswork Situation Manager.

Note: A team's Service Filter can be configured by a user with Administrator rights. This can be found under General > Teams > System Settings.

There are several ways to view a Situation from the Collaborate screen. One way is to click on the Situation ID in the Collaborate wall. Alternatively click the View button in the top corner of each panel:

Both of these options open the Situation Room for the Situation.

Creating a Comment

You can comment in a Team Room by clicking Write a comment at the top of the screen and starting to type.

When you have finished, you can click one of the icons to indicate the type of comment you are posting. The speech bubble icon is for general comments, the question mark is for questions and the lightbulb is for ideas.

Next click Post to add the comment to the Collaborate wall. Alternatively use the Ctrl+↵ or ⌘+↵ keyboard shortcut.

You can make additional comments in a comment thread. To do this, click Add a comment, type your message and press Enter to submit.

You can up vote or down vote comments using the buttons in the top right corner of the primary comment. You can only vote on Situation Room comment entries. You cannot vote on your own comments, only on comments made by other users.

Marking a Resolving Step

You can mark any suggestion from another user, such as tools which were run to resolve a Situation, as a 'Resolving Step'.

To do this, click the Resolving Step icon in the top right corner of the comment. This will highlight the comment with a green line:

The Resolving Step icon subsequently appears on any similar Situations. By default, similar Situations are deemed to be all those which share at least 50% of the same alerts.

A comment can be deselected as a Resolving Step at any time by clicking on the check icon again.

Attaching a File

You can attach a file such as a screenshot, error message or log file to any Collaborate wall.

To do this, click Attach File and select the file from any location on your local machine. Next create a comment as normal to accompany the attachment and then click Post.

The attachment appears in blue text alongside the file size in brackets.

Identify Next Steps

You can identify the recommended actions to take with a Situation under Next Steps. This tab is open by default when you first look at a Situation.

The next steps depend on the current status of the Situation and may include similar Situations with Resolving Steps or the alerts which are most likely to be the root cause of the Situation.

In the example above, the first required step is to acknowledge the Situation. To do this, click the Acknowledge button under 'Status' or Next Steps.

You can also see there is a similar situation with 70% similarity. If this had a Resolving Step, indicated by a check icon, you could click this to see what action was taken to resolve the similar Situation.

Probable Root Cause

If you have been training your Probable Root Cause model, you will see up to three alerts likely to be the root cause of the Situation. For more information about marking alerts for PRC and training your model see Check Situation Alerts .

Click Go To PRC Alerts to view these alerts in more detail.

There are no PRC alerts in this section if:

•      You have not trained your model.

•      You do not have any alerts with PRC equal to or greater than 50%.

Topology View and Important Nodes

If you enable Situation topology, you can see a visual representation of the connections within the Situation, based on topological data for the relevant nodes. You can put the Situation into context and gain a better understanding of its impact. The most important nodes in the Situation topology are listed together with Vertex Entropy data if available.

Click View in the Vertex Entropy column or Go to Topology View to display the Situation Topology tab. See View Situation Topology for more information.

Similar Situations

Cisco Crosswork Situation Manager identifies if two or more Situations are similar and groups them in a subsection of Next Steps called Similar Situations. You can use Next Steps to identify trends and reduce the number of escalations. For example, if a current Situation is similar to one that was previously resolved then the resolution information might be re-useable. Alternatively, if Situations recur at regular intervals, steps can be taken to prevent future occurrences.

 To generate similar Situations, Cisco Crosswork Situation Manager analyzes all Situations, calculates their similarity and highlights those with a similarity of 50% or above. This means at least half of the alerts are shared between two similar Situations.

For each similar Situation, Cisco Crosswork Situation Manager displays the Situation ID, similarity (%), the creation time, a description, any impacted services and the Situation Rating.

Click the date beneath 'Created at' for an exact time and date that the Situation was created.

Click 'Description', 'Impacted Services' and 'Rating' to make edits. Only users with the correct Role permissions can make edits to 'Description' and 'Impacted Services'.

Alternatively, click the Situation ID or View to open the Situation Room for the Similar Situation.

Merged Similar Situations

If a number of Situations share a high similarity and alerts, Cisco Crosswork Situation Manager merges them together automatically to create a new Situation.

By default, Cisco Crosswork Situation Manager carries out an automatic merge when Situations share a 70% similarity. If a Situation has been merged automatically or manually there will be a merge icon alongside the Situation ID:

Click the icon to show or hide the merge history. In this example, Situation #8 had an 90% similarity so was merged into Situation #24.

For more information about merging Situations see Merge Situations.

Similar Situations with Resolving Steps

If a Similar Situation has a Resolving Step, this is indicated by the check icon:

Click the check icon to reveal any Resolving Steps, which are comments that appeared in the Collaborate tab that led to or provided a resolution. Click the Resolving Step icon at the top of the panel again to close it. Alternatively you can add a comment or a vote if it was helpful or not.

Situation Rooms

The Situation Room is the virtual meeting place for all users involved in finding the resolution to the Situation and its alerts. This is where you will spend the most time when you are investigating the cause of a Situation.

At the top of the Situation Room you can see when the Situation was created, any impacted services, the alerts it contains and the rating it was given at resolution.

Situation Room Tabs

The Situation Room tabs along the top of the screen provide links to the Next Steps, Alerts, Timeline and Collaborate tabs which can be followed in a logical order.

Note: Additional tabs linking to third-party tools can be added in the form of Situation Room plugins.

Next Steps

The Next Steps tab offers you a suggested action step to take in relation to the Situation. The suggestion depends on the Situation's status, if it has similar Situations or if there are Resolving Steps.

You can collapse any of the items in the Next Steps tab by clicking on the down arrow to the left of the item name. You can expand the item by clicking on the right arrow beside its name.

Alerts

The Alerts tab is useful for looking at the Situation's individual associated alerts in more detail.

From here you can filter and identify the alerts of interest and then seek a resolution.

To activate the Select All checkbox, scroll down to load all alerts.

Timeline

The Timeline tab offers a powerful graphical view displaying the progression of a Situation with a breakdown of its associated alerts in the order they occurred.

Alongside the alerts, you can also inspect the markers where activity took place. See Analyze the Situation Timeline.

Collaborate

The final step is to collaborate with other users by looking at the comments and talking to colleagues.

The ultimate goal is to find a way to resolve the alerts and subsequently the Situation. See Collaborate on the Situation.

Invite Users to the Situation Room

You can invite team members who you think might be able to help resolve a Situation using the + invite button. You can only invite users who are members of your team by default.

Type the name of the user you want to invite, add a note if required and click Done. The invited user will receive the invitation as a notification. You can only invite others users to a Situation Room if you have been assigned to the Situation.

Note: You may only be able to invite members of your team to a Situation Room if your Administrator has configured team access only.

Other Situation Room Actions

There are a number of other actions that can be performed using the Tools and More Actions drop-down menus on the top bar of the Situation Room. For more information about these menus and other actions that can be performed see Take Additional Actions.

Check Situation Alerts

You can look at the Situation's associated alerts from the Situation Room by clicking the Alerts tab.

From here you can filter and identify the alerts of interest, typically those with the highest severity or that are impacting services, and then seek a resolution.

View Unique Alerts

You can switch between viewing all alerts and all unique alerts:

·         Click View and then either Show All Alerts or Show Unique Alerts to toggle between which group of alerts you want to display.

Mark Alerts for Probable Root Cause

Follow the steps below to mark individual alerts as a Probable Root Cause (PRC):

·         Click the circular PRC icon to mark an alert as a Probable Root Cause alert.

·            

·         When selected, the PRC icon turns blue. Cisco Crosswork Situation Manager also reports that PRC feedback is in progress.

·         If there are any alerts you know are not the root cause of the Situation, click the cross icon. This turns red when selected.

·         Click the Save button. The % PRC is indicated by the bars in the PRC column.

Note: If you do not know the status of an alert do not label it. You do not have to label every alert: PRC is effective with consistent data.

·         Open another Situation and look at the alerts. The PRC column automatically populates with estimated PRC values based on the user feedback.

See Probable Root Cause for more information about how PRC can help you reduce the time it takes to resolve Situations.

Analyze the Situation Timeline

The timeline offers a powerful graphical view displaying the progression of a Situation with a breakdown of its associated alerts in the order they occurred alongside key activity markers.

Use the timeline to analyze the Situation, see how it developed and determine the hotspots where there are higher volumes of more severe alerts.

Situation severity is determined by the highest severity of its alerts. In the example above, the Situation is critical because it contains Critical alerts, which is the highest severity.

Timeline Navigation

There are several components to the timeline tab which allow you to zoom in on a specific time, view Situation activity and display when alerts occurred.

Situation Activity

The Situation Activity panel will show activity markers at times where different things happened following the creation of the Situation.

The number indicates how many Situations activities occurred. Click on any of the activity markers for more details of what happened at that time.

In this example above, the five activities were: the creation of the Situation itself, it impacted the Ops Team, the Situation custom info was changed, 15 further Alerts were added to the Situation and then it was assigned to a User. The activity marker icons will differ depending on the type of activity that occurred.

Alerts and Event Details

The alerts are displayed in graphical form on the bottom of the Timeline tab, with each alert represented by a rectangular block the color of its severity.

You can view the details of the events within each alert by clicking each block. This opens the Event Details window. You can open the Alert Details window by clicking the Alert ID.

In this example, alert 94 contains events 200 and 201 which were detected by a Network Monitor.

Collaborate on a Situation

The Collaborate tab provides a chat environment where you can talk to your team members and resolve a Situation.

You can add comments, attach files, and view activity such as which teams are impacted and when the Situation was created or assigned to a user.

Navigation

To view all previous comments and Situation activity, scroll down to the bottom of the Collaborate view.

It works much like a social media news feed wall with the oldest comments and activity at the bottom and the latest at the top.

Create a Comment

To create a comment, click in the Write a comment box and start typing.

When you have finished, click Post to add the comment to the Collaborate wall.

Tip  Submit your post using the keyboard shortcuts Ctrl+Enter or Command+Enter.

To make additional comments in a comment thread, click Add a comment, type your message and press Enter.

You can up-vote or down-vote comments using the thumbs-up and thumbs-down buttons in the top right corner of the primary comment.

Custom Situation Room Tools

You can run a number of custom tools in the Situation Room that your admin has configured for you and your team. These might include Client tools, URL tools and tools triggered by ChatOps commands.

Run a ChatOps Tool

As well as comments, you can also run ChatOps tools to try and find a resolution to the issue. Generic Tools, Alert and Situation Server Tools, or Alert and Situation Client Tools can be run using the @moog or @bot command following by the configured ChatOps shortcut.

Note: An administrator must configure ChatOps and Tools. See Configure ChatOps for more information.Configure ChatOps Shortcuts

If the ChatOps tool was successful in resolving the issue, it can be marked as a Resolving Step.

Mark a Resolving Step

If a user makes a suggestion that resolves the Situation or its alerts, then it can be marked as a Resolving Step. To do this, click the Resolving Step icon in the top right corner of the comment. This highlights the comment with a green line:

The Resolving Step icon will subsequently appear on any Similar Situations.

Tip  Click the icon again to remove a Resolving Step.

Use the Show Filter

The Show filter can be used to filter which types of activity and comments appear in the Collaborate tab.

The different types can be added or excluded by checking or unchecking the boxes. These types include: workflow, tools, alerts, impact, modifications, invitations and posts.

View Situation Topology

Issues affecting different systems in your network can frequently be related to the same Situation. Cisco Crosswork Situation Manager uses topological data to present a visual representation of connections between the hosts impacted by a Situation.

The topology is host-based. Cisco Crosswork Situation Manager identifies hosts using the "host" field from alerts. Each host in your system is a potential node in the topology.

When a Situation affects more than one node and Cisco Crosswork Situation Manager has topological data for those nodes, you can use the Situation Room Topology tab.

Before You Begin

Your Administrator must follow these steps to enable the topology view in the Situation Room:

·         Run the topology builder utility to generate the topology data.

·         Optionally run the graph analyser utility if you want to generate Vertex Entropy data.

Once the topology builder utility has been run, the Situation topology automatically renders based on the contents of the Situation.

Topology Navigation

While in a Situation Room, click the Topology tab. You can toggle full screen view to hide the other elements on the screen and focus on the topology. Use the zoom buttons on the right side of the topology to zoom in and out. Node labels appear as you zoom in. Click and drag the nodes to rearrange the topology view. Hover your mouse cursor over a node to display its name, description and service data.Open the Display Options window to access options for relative node size, neighbor node selection and a description of the severity colors.

For example, consider the following topology that indicates a potentially serious Situation that requires immediate investigation. Two nodes (red) are critical, another two nodes (orange) are major and they are connected to other nodes that are as yet unaffected.

The following example shows a Situation with many involved nodes, some of which are critical:

·         A: The node with the highest Vertex Entropy value is critical in this Situation.

·         B: A solid line indicates a link between affected nodes. The higher severity determines the color of the line.

·         C: Several other nodes are involved in the Situation with varying levels of severity.

·         D: A dotted gray line indicates a link between unaffected nodes.

·         E: Gray nodes are not involved in the Situation but appear on the topology depending on the Neighbor Nodes selection.

View Neighbor Nodes

The topology displays affected nodes and their immediate neighbors, even if the neighbors are not involved in the Situation. Neighbor nodes provide context about the nodes in the Situation, relative to their location in the topology. For example, if you increase the number of neighbor nodes you may see that two nodes in the Situation are connected to the same switch, that is not part of the Situation.

Open the Display Options window on the left side of the topology view and use the neighbor nodes slider to control the number of neighbor nodes on display. You can show:

·         A maximum of 4 neighbors.

·         Up to 150 uninvolved neighbor nodes in total.

The maximum number of neighbor nodes on the slider corresponds to the total number of uninvolved nodes in the topology. For example, if a neighbor node level of 4 includes 151 uninvolved nodes, the slider maximum is automatically set to 3. There is no limit on the number of affected nodes you can display, however large topologies of 500+ affected nodes can take more than a minute to load.

View Alert Severity

The color of the node reflects the highest severity of its alerts. Open the Display Options window to see a description of the severity colors. Neighbor nodes that are not involved in the Situation are gray.

View Related Alerts

Click a colored node to display its related alerts in the alerts list beneath the topology. The selected node and its links are highlighted in the topology view and alerts affecting the selected node appear in the list. The alerts display with the same layout as the Situation Room alert list.

Filter Alerts

You can add filters to refine the list of alerts using full or partial matching. Nodes matching the filter are highlighted in the topology. For example, the filter "Host: web" will display all alerts with host names that include the string "web".

View Vertex Entropy

If you want the topology to indicate Vertex Entropy, your Administrator must run the graph analyser utility to generate the data. Open the Tools window and select Vertex Entropy. The size of the node indicates its Vertex Entropy. The larger the node, the higher the Vertex Entropy value.

View PRC

If you want the topology to indicate Probable Root Cause (PRC), ensure that PRC data exists for one or more alerts in the Situation. Open the Display Options window and select Probable Root Cause. The size of the node indicates PRC. The larger the node, the higher the PRC value.

Refresh the Topology

Cisco Crosswork Situation Manager does not automatically update the topology when alert details change. Click the Refresh button on the right side of the topology view to update the topology.

Merge Situations

You might want to merge multiple Situations into one Situation if they share a significant number of alerts, or if you think they all share the same root cause. Cisco Crosswork Situation Manager merges Situations automatically if they share 70% of the same alerts. You can also merge Situations manually from any of the Situation filter views and from a Situation Room.

Merge Two or More Situations

To merge Situations from a Situations view:

·         Select the Situations you want to merge: click the boxes in the far-left column.

·         Click Tools or right-click on the Situations to open the Tools Menu.

·         Click Add to Merge... to open the Merge Situations panel displaying the selected Situations. This appears at the top of the Situations view.

·         To add more Situations, repeat these steps. To remove Situations, click the x icons.

·         To complete the merge, click Merge Situations. A message appears with a link to the new Situation.

By merging Situations, you are combining all of the Situations' alerts so that the severity of the new Situation reflects the highest severity of those alerts.

Click Open Situation to open the Situation Room for the new Situation. From here you can click the merge icon to show the Situation's merge history and see the Situations which were merged to create it.

Take Additional Actions

You can use the menus and icons at the top of the Situation Room in Cisco Crosswork Situation Manager to perform additional actions on a Situation.

Tools

The Tools menu links to any Client Tools, Generic Server Tools and Situation Server Tools which have been set up by your Administrator. Client tools use Situation and alert data to carry out actions through a specified URL. Generic, Alert and Situation Server Tools allow a user to execute a utility on a remote host.

More Actions

There are a number of actions under the More Actions menu:

 

Note: Only users with the correct permissions can 'Own' or 'Assign' a Situation.

Situation Status

The Situation status shows the Situation's workflow journey. The highlighted item furthest to the right indicates the current status. For example, the status for the Situation below is "In Progress":

Click any of the subsequent statuses or actions in the row to change the Situation's status or perform an action.

When Cisco Crosswork Situation Manager creates a Situation, it is "Opened" by default. Then someone assigns it to a user who acknowledges it. When the user begins work, they update the status to 'In Progress'. When they have solved the issue, they mark it as 'Resolved'. Subsequently, someone can close the issue.

The following table provides full descriptions of all Situation statuses:

Advanced Usage

As an Operator, there are a number of procedures you can use to enhance your ability to work with Situations. You can use filters to search for specific alerts, Situations, and Impacted Services. You can schedule maintenance windows so that events created during these maintenance periods are not included in Situations. You can also identify alerts that are the Probable Root Cause of a Situation to improve the resolution of similar Situations that occur in the future.

Filter Search Data

You can search for specific alerts, Situations, and Impacted Services in Cisco Crosswork Situation Manager using filters. The default filter views that you can access from the Workbench are Impacted Services, My Situations, Open Situations, My Alerts, and Open Alerts.

There are two types of the filter: Basic Filter and Advanced Filter. Click the funnel filter icon to open the drop-down menu and switch between the filter types.

Note: Cisco recommends that you use the Basic Filter in most cases but, if you want more flexibility or need to filter for something more complex, then use the Advanced Filter.

Create a Basic Filter

To use the Basic Filter:

·         Click in the "Filter" bar. A drop-down menu appears with available fields.

·         Select a field and any values as required; then click Apply or click away from the menu.

·         Repeat this for as many fields as you want to add to your filter.

·         Alternatively, type the name of the fields you want to apply to the filter.

·         Once you have entered one or more fields, click away from the menu to apply the filter.

Alert Column Parameters

You can use the columns and operators displayed in the tables below in your Basic Filter:

Situation Column Parameters

Create an Advanced Filter

The Advanced Filter is for complex queries and operates in a similar way to the Basic Filter but uses the Cisco filter query language which is based on SQL. For example, to show all Situations with a 'Severity' of 'Warning' and a 'Description' of 'SocketLam Sigalised', the correct syntax would be:

(Internal Severity IN ("Warning")) AND (Description MATCHES "SocketLam Sigalised")

For more information on the query language syntax, see the tables of available operators and the examples below.

Pause Alerts and Situations

Click the Pause button to temporarily stop alerts or Situations being added to the Alert or Situation View.

Note: When paused, Cisco Crosswork Situation Manager does not update the list with the latest data unless you apply a new filter which triggers a one-time load of data.

After any edits have been made, the live feed of data can be reactivated again by clicking the Play button.

Advanced Filter Syntax

The Advanced Filter query syntax can be used to create more complex filters for Alerts and Situations. This syntax uses column display name parameters alongside common query operators used in filters. The column parameters and their associated operators are listed in the sections below.

Note: The Advanced Filter query syntax uses the display column names (those shown in the UI) rather than the database column names.

Alert Column Parameters

Situation Column Parameters

The associated operators are described in the tables below.

Comparison Operators

Literal Operators

Logical Operators

Other Operators

Creating an Advanced Filter

When creating an Advanced Filter, it should contain at least one column name, an associated operator, and a value. As a general rule, the column name should always be to the left of the operator.

If the column name or the value contains a space, it needs to be surrounded by single or double quotation marks (both " " and ' ' are accepted). This applies to columns such as External ID, Last Event Time, Last Change, Scope Trend etc. For example, 'External ID' MATCHES 01 or "External ID" MATCHES 01 are both valid.

Column names are case insensitive but the values are case sensitive. For example, 'severity' = 'Critical' is valid but 'severity' = 'critical' is not.

If you want to create a filter where the owner is empty, enter 'Owned By' = 'Moog'.

If the syntax is incorrect or invalid then the filter bar will flash, see screenshot below:

For reference, please see the examples and screenshots displayed below.

Filter on Custom Info Fields

You can filter on custom info columns in Alert and Situation Views. The syntax for advanced filters uses the CONTAINS keyword. The following is an example for a custom info column named "servers.kingston":

custom_info.servers.kingston CONTAINS "kngstn::webserver::HR"

You must use full matching, rather than partial matching, which means that the whole value in the filter must appear in the list. For example, the above filter requires the list to have a "kngstn::webserver::HR" element. It does not, for example, match "kngstn::webserver".

Quotes are optional for both strings and number values. Note that no brackets are allowed around the filter value.

For this feature to work, the custom info column (in this example, "servers.kingston") must be added as a filterable column. This can be done in the UI, under System Settings > Alert / Situation Columns, or via the utilities: moog_add_alert_custom_info_field and moog_add_situation_custom_info_field. The column type must be a list (in the UI) or JSON (via a utility).

Advanced Filter Examples

Example 1

Severity = 'Minor' AND Description = 'Web Situation'

In this example, the filter shows all alerts with 'Minor' severity and with the description 'Web Situation':

Example 2

Severity = 'Critical' OR (Severity = 'Major' AND description = 'SocketLam Sigalised')

In this example, the filter shows all alerts with 'Critical' severity, or 'Major' severity and with a type of 'SocketLam Sigalised':

Example 3

Type MATCHES 'Anomalyflag' AND Count = 1

In this example, the filter shows all alerts which match the 'Anomalyflag' type and have a count of 1:

Schedule Maintenance Downtime

To reduce unnecessary noise, you can define Maintenance Windows for scheduled downtimes, such as during server or software upgrades.

During a maintenance window, events continue to be correlated into alerts and labeled as 'In Maintenance' but you can choose not to group them into Situations. If an alert under a maintenance schedule receives an event, it is tagged as such.

Create a Maintenance Window

Click Create Maintenance Window to create a new window:

 

Note: Historical, expired and manually deleted windows are not displayed here. If you are an Administrator, you can edit one of the displayed windows by double-clicking it.

Identify Probable Root Cause

Probable Root Cause (PRC) is a machine learning process in Cisco Crosswork Situation Manager that identifies which alerts are responsible for causing a Situation. PRC looks for patterns in user supplied feedback. It does not use 'Root Cause Analysis' techniques. Probable Root Cause offers the following benefits:

·         You can immediately determine where to begin troubleshooting and diagnosis as soon as you open a Situation by looking at the Probable Root Cause alerts.

·         You can resolve Situations quickly by examining the top 3 Probable Root Cause alerts that appear under Next Steps in a Situation Room.

For a brief introduction on Probable Root Cause, watch the following video:

How Does PRC Work?

You manually label alerts as either a Root Cause Alert or a Symptom alert, the Cisco Crosswork Situation Manager PRC Model uses this data to predict Situation root causes. Watch the following video for more information on labelling alerts:

When Cisco Crosswork Situation Manager generates Situations, it labels an alert or alerts as having a Root Cause Estimate. A Root Cause Estimate is always assigned even if the data set is small. The more data Cisco Crosswork Situation Manager has, the more accurate it is.

Note: The data needs to be consistent and the model is only as effective as the data you supply. For example, two conflicting labels will confuse the model. If you do not know the status of an alert, do not label it.

How Does Cisco Crosswork Situation Manager Learn?

Machine Learning uses features like Severity, Host, Description and Class and takes the values of those features for all labelled alerts and uses a Neural Network to estimate the Root Cause for all the alerts in a newly created Situation. It does this even if that Situation has not been seen before based on the model and labelled data.

See Configure and Retrain Probable Root Cause for more information on training your model.Configure and Retrain Probable Root Cause

PRC Column

The PRC column, on Situation and the alerts tabs, shows the Probable Root Cause Estimate as a percentage of the alerts in that Situation and is useful as a prioritization aid. For example, the higher the value an alert has, the higher the probability that the alert is the root cause of the Situation.

As alerts are added to a Situation, the Root Cause is recalculated on the Situation and alerts lists, so the PRC values may change. The more accurate and consistent data you feed your model is, the more accurate the estimate.
