Getting Started
The following topics will help you understand and start using Performance Monitor:
•
Logging In to and Exiting Auto Update Server
•Understanding User Permissions
•Using the Performance Monitor Interface
•Working in an Event Browser
•Sequence of Performance Monitor Operations
Logging In to and Exiting Auto Update Server
You log into Performance Monitor using the Cisco Security Management Suite home page. You can also use the home page to install the Security Manager client or to access Common Services, Auto Update Server, RME, and other software installed into Common Services.
Procedure
Step 1 In your web browser, open one of these URLs, where PMServer is the name of the computer where Performance Monitor is installed. Click Yes on any Security Alert windows.
•If you are not using SSL, open http://PMServer:1741
•If you are using SSL, open https://PMServer:443
The Cisco Security Management Suite login screen is displayed. Verify on the page that JavaScript and cookies are enabled and that you are running a supported version of the web browser. For information on configuring the browser to run Security Manager, see Installation Guide for Cisco Security Manager.
Note We recommend that you use SSL for proper security.
Step 2 Log in to the Cisco Security Management Suite server with your username and password. When you initially install the server, you can log in using the username admin and the password defined during product installation.
Step 3 When you log in, you are shown the Cisco Security Management Suite home page. The home page lists the suite applications installed on the server. You can access at least the following features on the server running Performance Monitor. Other features might be available depending on how you installed the product.
•Performance Monitor—Click this item to open the Performance Monitor interface.
•Server Administration—Click this item to open the CiscoWorks Common Services Server page. CiscoWorks Common Services is the foundation software that manages the server. Use it to configure and manage back-end server features such as server maintenance and troubleshooting, local user definition, and so on.
•CiscoWorks link (in the upper right of the page)—Click this link to open the CiscoWorks Common Services home page. You can also access Performance Monitor from this page.
Step 4 To exit the application, click Logout in the upper right corner of the screen. If you log out of any window for the server (for example, the Performance Monitor window or the Security Manager home page), you are logged out of all windows.
Login sessions time out after 2 hours of inactivity.
Understanding User Permissions
Your server authenticates the username and password of every user who logs in. After you start Performance Monitor, Common Services identifies the tasks and operations that you are authorized to perform based on your assigned role. Some tasks and related interface elements are hidden from unauthorized users. A user with system administrator privileges can access all features, while other users see only a subset of features. For example, a system administrator can display any scheduled email report job, regardless of who created it, while other users can display only the email jobs that they have created.
Performance Monitor user authentication and authorization come from Common Services. See the Common Services online help for details.
Note You can configure Common Services to use Cisco ACS for the management of user accounts on your server. See "Configuring CiscoWorks Common Services to use Cisco Secure ACS Authorization and Authentication" topic in the Common Services online help.
Common Services provides seven user roles. The following table describes how those roles correspond to Performance Monitor tasks and interface elements.

Using Performance Monitor Tables
Tables contain items such as devices and critical problems; you can perform certain optional tasks in almost any page that contains a table. But Performance Monitor tables might differ in some ways from the tables you use in other applications, and might sometimes include unfamiliar traits like a troubleshooting function for your network devices and services. Also, some tables span multiple pages.
Figure 3-4 Example Table
1
|
Column heading — The column heading appears above table data and spans the width of the table. Entries in the column heading identify the type of information provided in each column. In many cases, you can click a column heading to re-sort the entire table by the entries in that column.
|
2
|
Row — One row describes one item, and each row provides several descriptors for the item. For example, a row might describe a single device by listing its IP address, device family (such as VPN 3000 Concentrator), and alarm state.
|
3
|
Column — A column provides a single category of information that applies equally to several items. For example, a column might list IP address information or the alarm state for all listed devices. In cases where the information in a column is a measured value, it is almost always one of these:
•Delta—The scope of difference from one polling cycle to the next.
•Whole value—A count, such as the number of active VPN tunnels on a device or the exact duration of a user session.
|
Tables That Span Multiple Pages
A single table might span multiple pages when the number of rows is insufficient to display all relevant data in a single page. In most cases, tables span multiple pages because either:
•You selected too few rows in the Rows per page list.
•Even the maximum value in the Rows per page list—40 rows—is insufficient to display the entire table in one page.
In these cases, use the navigation buttons (Figure 3-5) under the table, or enter a table page number in the Go to page text box, then click Go.
Figure 3-5 Table Navigation Buttons

|
Table Check Boxes
A check box is present in a row when that row describes an item that you can edit or for which you can take an action. Optionally, you can select items row by row, or you can select the check box in the column heading to select all items.
Table Actions
If you plan to edit an item in a table, select its check box, then click the appropriate action button. Buttons that are not relevant to a selected item, or for which you do not have permissions, are grayed-out.
Common Elements in Tables
Table 3-2 describes elements that recur in most Performance Monitor tables.

|
Select an option from the list to change the maximum number of table rows displayed in each page. An automatic screen refresh follows your selection.
|
check boxes
|
Select the entry or entries to which an action applies. You can select entries individually, or you can select all entries simultaneously.
•A check box in the column heading row permits you to select or deselect all entries at once. (In a table that spans two or more pages, you select only the entries in the active page.)
•A check box in a row that describes one entry permits you to select that entry individually.
Note You must select the entries to which an action applies before you perform the action.
|
Troubleshoot button
|
Troubleshooting information developed by Cisco Systems is part of the Performance Monitor application. The interactive troubleshooting tool is available online only, in these two ways:
•From the Troubleshoot button, where it appears in the interface. (Some pages do not include the Troubleshoot button.)
•From the table of contents for the Performance Monitor online help.
|
Refresh button
|
For a one-time, manual refresh of the active page, click Refresh.
Displayed values in the refreshed page are based upon data that was collected during the most recent polling cycle or from traps received from devices regarding the condition of their interfaces, real servers, or site-to-site VPN tunnels.

The displayed time and the time zone abbreviation are those in your location, regardless of the location of the CiscoWorks Server.
|
Using Wizards
Wizards lead you step-by-step through otherwise complicated tasks like importing or adding devices. Figure 3-6 shows a representative page from the Importing Devices wizard. The wizard elements are:
Figure 3-6 Example Wizard Page
1. Table of contents (TOC) that lists the wizard steps.
2. Wizard pages.
3. Wizard action buttons.
A TOC lists the steps in the wizard, and TOC entries for steps you have completed are links that allow quick navigation back to a specific step or field. You must complete steps in a strict sequence when you work in a wizard. If you try to vary the sequence or leave the wizard too early, an error message is displayed and your action is blocked. Wizard action buttons differ according to the step that you select:
•The Back and Next buttons are grayed-out in the first and last steps, respectively.
•To exit the wizard without saving your changes, click Cancel.
•To submit your changes, then exit the wizard, click Finish.
Until you click Finish, Performance Monitor does not apply any of your selections. When you click Finish, you skip whichever steps remain undone in the wizard. Most wizards have defaults, which are applied to the steps that you skip.
Using an Object Selector
Object selectors are based on a framework of folders, subfolders, and their contents, and appear in many different pages in Performance Monitor. The elements in an object selector vary slightly, depending on its purpose. An object selector typically shows a nested tree of device groups, devices, and — sometimes — events, and lets you select devices and events as filtering criteria.
Figure 3-7 Object Selector Elements
1
|
All tab — Enables you to view and select:
•Event categories, device groups, and individual devices so that you can filter the displayed results in an event browser window.
•Device groups (system-defined or user-defined) and individual devices so that you can:
–Restrict the scope of a report that you configure.
–Edit SNMP settings and polling credentials.
–Enable or disable polling.
–View device properties.
–Delete devices.
•User-defined device groups and individual devices so that you can:
–Create, modify, or delete user-defined device groups.
–Display device group details.
|
2
|
Selection Tab — Enables you to isolate and display a complete list of the objects that you select under the All tab. To remove an object from the list of selections, deselect the relevant check box.
|
3
|
Event Categories folder — Contains events that you can select. Where it exists in the left pane of an event browser window, you can click the Event Categories folder to select all events. Alternatively, you can expand the folder and select one or both of the event categories it contains:
•Failure—Also known as state events, failure events pertain to conditions for which only extreme values exist, such as Up and Down.
•Performance—Also known as range events, performance events pertain to conditions for which a range of values exist, such as OK, Degraded, and Overloaded.
|
4
|
Device Groups folder — Contains the Monitored Devices folder at its root level. The Monitored Devices folder, in turn, contains additional nested subfolders that categorize the different types of monitored devices in your network. These subfolders include system-defined device groups and might include user-defined device groups. You can select devices individually, or device groups individually, or you can select all of your device groups.
|
5
|
Apply Filter button — To apply your selections, click Apply Filter.
Note Some Object Selectors do not display an Apply Filter button. In such cases, your selections take effect immediately.
|
6
|
You might see a + symbol or a - symbol to the left of some folders or subfolders in the selection tree. Click a + symbol to expand, or click a - symbol to collapse, the relevant level in the tree.
|
7
|
Select the check box next to an object to select that object and all its descendants in the hierarchy. Click again to deselect an object.
Note In an Object Selector, you must select at least one check box before you click an action button. For example, when you configure a report, you must select a check box to specify the device or group to which the report applies.
|
Working in an Event Browser
An event is a notification that a monitored device or component has an abnormal condition. Multiple events can occur simultaneously on a single monitored device or service module.
An event browser window allows you to browse events and sort or filter events by criteria you choose. Performance Monitor provides filtered and unfiltered event browser options.
To open an event browser window, do any of the following:
•Under the Summary tab, select the Event Browser option. The event browser that opens describes all monitored events in your network, irrespective of their service type or the device on which they occur.
•Under the Summary tab, click any linked entry in the Critical Problems table. The event browser that opens describes only the events on the relevant device.
•In any TOC under the Monitor tab, click Event Browser. The event browser that opens describes only the events that affect the relevent service.
•Under the Monitor tab, click any hyperlinked alert icon in a table that includes an Alert column. The event browser that opens describes only the events that affect the relevant service on the relevant device.
When the event browser window opens, its left pane contains an Object Selector. See Using an Object Selector.
The following table describes some typical tasks that you can perform with an event browser. Additional tasks are explained in Optional Tasks in Performance Monitor Tables. For a general reference of event browser window elements, see Event Browser Windows.
Table 3-4 Typical Tasks in Event Browser Windows

Procedure
|
Use event categories to filter the events list.
|
You can view and select event types in the left pane to filter results in the right pane.
1. If the Event Categories folder is closed, click the + symbol to its left.
The folder expands. It contains event categories that you can select individually.
2. Select the check box to the left of an event category to select that category. Or, select the check box to the left of the folder to select all event categories.
3. Click Apply Filter.
The refreshed display shows only events that match the category (or categories) you select.
|
Use devices or device groups to filter the events list.
|
You can view and select device groups or individual devices in the left pane to filter results in the right pane.
1. If the Device Groups folder is closed, click the + symbol to its left.
The folder expands. You can further expand the nested subfolders to view device categories and, finally, individual devices.
2. Select the check box to the left of a folder to select that folder and all of its descendants. Or, select the check box to the left of a device to select that device only.
3. Click Apply Filter.
The refreshed display shows only the events on devices that you select.
|
Use severity levels to filter the events list.
|
To specify a severity level range (where P1 is the highest severity and P5 is the lowest), select the relevant option in the Select Severity list.
Performance Monitor applies the filter immediately and the event browser refreshes automatically to display the filtered result. The refreshed display shows only events within the specified severity range.
|
Use alarm states to filter the events list.
|
To specify an alarm state, select the relevant option from the Alarm Status list.
Performance Monitor applies the filter immediately and the event browser refreshes automatically to display the filtered result. The refreshed display shows only events within the specified alarm state (or states, if you select All).
Note Your selection in the Alarm Status list cannot be combined for filtering purposes with any selection in the Event State list. If you make selections in both lists, your second selection clears and overrides your first selection.
|
Use event states to filter the event list.
|
Select a value from the Event State list in the right pane. Available options in the Event State list can vary as follows:
•Generic—Options in the list are a superset of all possible states.
•Service—Options in the list are only those that pertain to the specified service, such as states that can exist, for example, in a site-to-site VPN.
•Device—Options in the list are only those that pertain to the specified device, such as states that can exist, for example, in a VPN 3000 Concentrator.
•Combined Device and Service—Options in the list are a superset of all the states that are possible both for the specified service and for the specified device type.
Note Your selection in the Event State list cannot be combined for filtering purposes with any selection in the Alarm Status list. If you make selections in both lists, your second selection clears and overrides your first selection.
Performance Monitor applies the filter immediately and the event browser refreshes automatically to display the filtered result.
|
Use ranges of time to filter the events list.
|
Select a value from the Time list in the right pane.
Performance Monitor applies the filter immediately and the event browser refreshes automatically to display the filtered result.
|
Use an Event ID to isolate and display a single event.
|
When Performance Monitor sends an email message to notify you about an event, it provides you with the sequential ID number it has assigned automatically to that event.
To view the details of an event, enter its ID number in the Event ID text box, then click Find.
Note An Event ID search is independent of any previous filtering.
|
Use a keyword or term to search for and display events that match a description.
|
You can isolate and view only the events that match a text string that Performance Monitor uses in its descriptions of events. For example, you could view only the events whose descriptions include such strings as not accessible, failure, or inbound.
Enter a string in the Description text box. Then, to view only the events whose descriptions include that string, click Search.
Queries are not case-sensitive.
Note A description search is independent of any previous filtering.
|
Event Browser Windows
The following table describes elements in an event browser window.
Table 3-5 Event Browser Window Reference
Element
|
Description
|
Object selector
|
The left pane contains an object selector, which is explained in Using an Object Selector.
|
Select Severity list
|
Enables you to select a severity level or range. The refreshed display includes only the events that match your selection, where P1 is the highest severity and P5 is the lowest.
Select the All option to view problems from P1 to P5 and resolved problems for which the severity is now set to OK.
|
Select Time list
|
Enables you to restrict the display to events that occurred in a specific timeframe.
|
Event State list
|
Enables you to select a value. The refreshed display includes only the events triggered by a particular event state.
Event trigger values in the Event State column or in the Event State list are the same values as those that you define or modify in event-specific threshold settings under the Administration tab:
•Extreme, opposite values such as Up and Down apply to failure events.
•Values within a range, such as OK, Degraded, and Overloaded, apply to performance events.
Note The exact values in a Event State list vary, depending on the service (or services) to which the displayed events apply. The State list includes all possible values when you select Summary > Event Browser. Otherwise, it displays only those states that apply to the relevant service.
|
Alarm Status list
|
Enables you to select an alarm state. The refreshed display includes only the events that match the alarm state you specify. The listed states are: All, Active, Cleared, and Acknowledged.
|
Event ID text box
|
Enables you to view detailed information about an event notification that Performance Monitor sent to you.
Enter the provided event ID number in the text box, then click Find.
Note An Event ID search is independent of any previous filtering.
|
Description text box
|
Enables you to define a query by which you can view only the events whose descriptions contain a specific text string.
Enter a keyword or term to define the parameters of your query. Acceptable parameters are limited to words or terms that match any part of any value Performance Monitor might display in the Description column.
To view only the events whose descriptions include the string you entered, click Search.
Note A description search is independent of any previous filtering.
|
Device column
|
Displays the DNS names of devices that provide the relevant monitored service.
The possible entries vary, according to which event browser window is open. For example, in the Firewall Event Browser, the Device column lists the DNS names of firewall devices and the DNS names of switches that contain one or more firewall service modules.
|
Severity column
|
Displays a severity level. The highest severity is P1; the lowest is P5.
|
Type column
|
Displays the type of event for which the relevant service has exceeded its threshold in this instance. Possible entries in this column are the same as the options you see when you define an event-specific threshold for the relevant monitored service.
You can display a complete list of the event types for a service if you select Administration > Notifications, then expand a service folder in the selection tree.
|
Description column
|
Describes the effect of the event on the service. For example, the description might say that bandwidth is low, or a VPN is down.
See the Description text box row in this table to understand how you can isolate and view only the events that match a particular description.
|
Event ID column
|
Displays the numeric ID that Performance Monitor associated with the applicable event for administrator notification purposes.
The ID numbers that Performance Monitor assigns are sequential over time, so the numeric ID of a new event is greater than the ID of an older event. When you sort the table by values in the Event ID column, you are sorting chronologically.
See Working with Notifications, page 12-1, to understand notification options in Performance Monitor.
|
Event State column
|
Displays the event state value that triggered the relevant event.
See the Event State list row in this table for related details.
|
Alarm Status column
|
Displays the alarm status for the relevant event—either Acknowledged, Active, or Cleared.
|
Product column
|
Displays a generic device type.
Tip For detailed information about a particular device, place your pointer over the device name where it appears in the Object Selector.
|
Occur Time column
|
Displays the time at which polling recorded the described event.
The displayed time and the time zone abbreviation are those of the CiscoWorks Server, regardless of your own location.
|
Clear Event
|
Clears the selected event. After you clear an event, the alert icon might still be displayed in the device monitoring windows up to a minute or until the page is refreshed, whichever occurs first.
|
Note You can select an option in either the Event State list or in the Alarm Status list. Your selection of any option in either list resets the selection in the other list to "All."

MCP Process Maintenance
Performance Monitor polls a large number of devices frequently, for which it requires a server process called MCP. To improve overall performance on your server, a scheduled job called restartMCP.pl stops and then restarts the MCP process once a week, on Sundays at 3:30 a.m. The script issues the pdterm MCP command and waits 1 minute, then issues the pdexec MCP command.
Note•The restartMCP.pl job also stops and then restarts the McpDbEngine process.
•The scheduled recurrence of the restartMCP.pl job is based on the local time of the server on which you installed Performance Monitor.
Tip•To display a list of scheduled jobs, go to the Windows command line and enter at, then press Enter.
•You can edit the entry for the restartMCP.pl script to modify its schedule.
Until the MCP process restarts:
•No device polling occurs.
•No new or recurring validation tasks run.
•Performance Monitor loses any SNMP traps that monitored devices send.
•You cannot add or import new devices.
The Performance Monitor interface is not affected and you can work from stored data, but some of the displayed data might not match the current condition of the devices and services in your network. Also, when you run historical reports, you might see a dip in the displayed graphs for any period of time in which the MCP process did not run.
The shutdown and restart of the MCP process generally takes less than 5 minutes.
Sequence of Performance Monitor Operations
After you configure Performance Monitor and it is operating as you intend, it performs certain operations automatically, in the following sequence:
1. Runs scheduled validations to verify that devices exist and are reachable, provided device credentials are correct, required features are enabled, and required interfaces are enabled.
For a VPN 3000 Series concentrator, validation also confirms that the relevant concentrator uses the correct XML credentials, has HTTPS enabled, and is running the VPN 3000 Concentrator Series Manager.
2. Updates the list of devices to poll, based on the results of scheduled validations.
3. Polls reachable devices for their current status, in order to compare device status information to performance and failure thresholds, generate performance and failure events, send event notifications, when appropriate, and update the values in tables and graphs.
Note If devices do not respond to the poll within the timeout period, polling to all devices stops. For more information, see Configuring the Polling Time Out, page 2-16.
4. Updates logs (continuously).
5. Performs scheduled and recurring jobs.
