This chapter describes the monitoring tools available in the Cisco WAAS Central Manager GUI that can help you monitor activity, configure flow monitoring, and customize reports.
For information on Cisco WAAS system logging and troubleshooting, see the “Troubleshooting Your Cisco WAAS Network” chapter and see the Cisco WAAS Troubleshooting Guide for Release 4.1.3 and Later on Cisco DocWiki.
Note Throughout this chapter, the term Cisco WAAS device is used to refer collectively to the WAAS Central Manager and Cisco Wide Area Application Engines (WAEs) in your network. The term WAE refers to WAE and Wide Area Application Virtual Engine (WAVE) appliances, and Cisco Virtual WAAS (vWAAS) instances.
The Cisco WAAS Central Manager GUI allows you to view general and detailed information about your Cisco WAAS network from the System Dashboard window. This section describes the System Dashboard window and contains the following topic:
Note For information on viewing the alarm panel and on viewing device alarms, see Cisco WAAS Central Manager Alarm Panel in Chapter 16, “Troubleshooting Your WAAS Network.”
Figure 15-1 shows the System Dashboard window.
Figure 15-1 System Dashboard Window
The information displayed in the charts in the System Dashboard window is based on a snapshot of your WAAS network that represents the state of your WAE devices at the end of every two polling periods. You can configure the interval between polls in the WAAS Central Manager GUI (Configure > Global > System Properties > System.monitoring.collectRate). The default polling rate is 300 seconds (5 minutes). Alarms are presented in real time and are independent of the polling rate.
The default System Dashboard window contains the following graphical displays about the application traffic processed by your WAAS system:
Numbers shown in charts and graphs are rounded to whole units (KB, MB, or GB), while those displayed in tables are rounded to three decimal places. Data values exported to CSV files are in bytes, and are therefore, not rounded.
You can customize the graphical displays and tables that are displayed on the system dashboard. For more information, see Customizing a Dashboard or Report. Individual charts are described in more detail in WAAS Chart Descriptions.
Much of the device, statistical, and alarm information that is presented in the system dashboard and associated graphs and charts is also available programmatically through the monitoring API. For more information, see Cisco Wide Area Application Services API Reference .
Note You must synchronize the clock on each WAE device within 5 minutes of the primary and secondary WAAS Central Managers for statistics to be consistent and reliable. For information on using an NTP server to keep all your WAAS devices synchronized, see Configuring NTP Settings in the “Configuring Other System Settings” chapter. Additionally, if the network delay in the Central Manager receiving statistical updates from the WAEs is greater than 5 minutes, statistics aggregation may not operate as expected.
This section describes how to use the WAAS Central Manager device windows:
The Devices window lists all the WAAS devices that are registered with the WAAS Central Manager. To view this list, choose Devices > All Devices in the WAAS Central Manager GUI.
Figure 15-2 shows an example of the Devices window.
This window displays the following information about each device:
– Green—No alarms (the system is in excellent health)
When you hover your mouse over the alarm light bar, a message provides further details about the number of alarms. Click the alarm light bar to troubleshoot the device. Location associated with the device. For more information about locations, see the “Using Device Groups and Device Locations” chapter. You can view reports that aggregate data from all the devices in a location. For more information, see Location-Level Reports.
WAE devices that are at a later software version level than the WAAS Central Manager are displayed in red. Also, if the standby WAAS Central Manager has a different version level from the primary WAAS Central Manager, the standby WAAS Central Manager is displayed in red.
You can filter your view of the devices in the list by using the Filter and Match If fields above the list. Enter a filter string in the text field and click Go to apply the filter. The filter settings are shown below the list. Click Clear Filter to clear the filter and show all the devices. Filtering allows you to find devices that match the criteria that you set.
Note After the devices has been registered to the WAAS Central Manager (WCM), a WCM DB VACUUM (runs between 1 AM – 2 AM) process takes more time (Min:2 min, Avg:7 min, Max:25min) due to the augmented load on computing resources.
- Few of the WAEs may go temporarily offline. They are online automatically once the VACUUM process is complete.
- Statistics Aggregation threads may take more than 5 minutes and the same would be indicated in the logs. As a result statistics samples, might be missing at network level.
- User, including the administrator will not be able to use (login) the WCM as the complete DB will be locked.
The Device Dashboard window provides detailed information about a WAAS device, including device model (such as WAVE-7541-K9 or OE-VWAAS-KVM), IP address, interception method, and device-specific charts. (See Figure 15-3.)
To access the Device Dashboard window, choose Devices > device-name.
Figure 15-3 Device Dashboard Window
The Device Dashboard window for a WAAS Express or AppNav-XE device looks slightly different. It lacks some WAE-specific information and controls.
From the Device Dashboard window, you can perform the following tasks:
The Device Status Dashboard window, shown in Figure 15-4, lists all the WAAS devices that are registered with the WAAS Central Manager. To view this list, choose Home > Monitor> Network> Device Status in the WAAS Central Manager GUI.

The filter settings are shown below the list. Click the Clear Filter button to clear the filter and show all devices. Filtering allows you to find devices in the list that match the criteria that you set.
To view the users defined on a WAAS device, go to Devices > device-name, and then, from the device-name menu, choose Device Users. On a Central Manager device, choose CM Users).
The list of users is displayed in a table, which shows the username, number of login failures, maximum number of login failures allowed, and the time of the last failed login. To view the details of a user, click the View icon next to that username.
If a user is locked out because the user has reached the maximum number of failed login attempts, unlock the user by checking the check box next to the username and clicking Unlock below the table.
Configuration conflicts between the device group and devices are difficult to identify at the device group level. Whenever configuration conflicts occur, they show up in the Force Device Group Detection page. The WAAS Central Manager provides an easy way to identify, view and resolve these configuration conflicts.
Note Force Device Group detection is not applicable for Cisco routers.
To identify the configuration conflict pages,
Step 1 From the WAAS Central Manager navigate to Home > Admin > Force Device Group > View Pages to see the impacted Device Name, Device Group Name and Page Name. This lists all the device groups that have conflicts with the devices and on which page.
Step 2 Click on the page link to navigate to the corresponding page to correct the configuration conflict by selecting FDG as mentioned in Procedure for Forcing Device Group Settings.
You can customize the system and device dashboards and reports, if any, in the same way. For more information about creating custom reports, see Managing Reports.
This section contains the following topics:
An example of a report is shown in Figure 15-5.
Taskbar icons and controls across the top of the dashboard or report allow you to do the following:
– Last Hour —Displays data for the past hour, in five-minute intervals (default). You can change the interval using the System.monitoring.collectRate configuration setting described in Modifying the Default System Properties in the “Configuring Other System Settings” chapter.
– Last Day —Displays data for the past day (in hourly intervals).
– Last Week —Displays data for the past week (in daily intervals).
– Last Month —Displays data for the past month (in daily intervals).
– Custom—Enter starting and ending dates in the From and To fields. Click the calendar icon to choose dates from a pop-up calendar.
The time frame setting is stored individually for each report and Central Manager user. Additionally, the System.monitoring.timeFrameSettings system property controls the system default time frame setting (see Modifying the Default System Properties in the “Configuring Other System Settings” chapter).
Note If you create a chart with a custom date setting that spans more than two months prior to the current date, data for the most recent two months are plotted with daily data and data for all the earlier months are plotted with aggregated monthly data. The chart might appear to have a large drop in traffic for the most recent two months because the daily traffic totals are likely to be much smaller than the monthly traffic totals. However, this difference is normal.
– UTC —Sets the time zone of the report to UTC.
– CM Local Time —Sets the time zone of the report to the time zone of the WAAS Central Manager (default).
When you change the time zone, the change applies globally to all reports. The time zone setting is stored individually for each Central Manager user.
– In the Date field, enter the schedule date in the format DD/MM/YYYY or click the calendar icon to display a calendar from which to choose the date.
– From the Hours drop-down list, choose the hours. The time represents the local time at the WAAS Central Manager.
– From the Minutes drop-down list, choose the minutes. The time represents the local time at the WAAS Central Manager.
– From the Frequency drop-down list, choose Once, Hourly, Daily, Weekly, or Monthly for the report frequency.
– In the No. of Reports field, enter the number of times that a reoccurring report is to be generated. (After a report is generated a specified number of times, the report is no longer generated.)
– In the Email Id(s) field, enter the email addresses of the report recipients, separated by commas.
– In the Email Subject field, enter the subject of the email message.
Controls at the top of individual charts allow you to customize the chart as follows (not all controls are available in every chart):
Chart-type icons at the bottom of individual charts allow you to choose the chart type as follows: column chart, line chart, area chart, stacked line chart, stacked area chart. Note that not all charts have this feature.

Step 4 (Optional) From the Select Series For drop-down list, choose one of the following:
Step 5 (Optional) In the Application or Classifier list, check the check box next to the applications or classifiers whose statistics you want to include in the chart data. To include all the applications, check the All Traffic check box. You can filter the list items by using the Quick Filter above the list. These lists are available only for some chart types.
Step 6 (Optional) Some charts have other types of data series from which to choose. Check the check box next to each of the data series that you want to include in the chart data.
Note Data collection for applications and classifiers occurs at slightly different times in the Central Manager. Therefore, the statistics can be different when viewing the same time period for an application and a classifier that report similar data.
This section describes the charts that you can choose to include in a dashboard or report. For tables that provide information on system, device, traffic and acceleration, see WAAS Table Descriptions,
The following chart categories are available:
All charts are created using the Central Manager local time zone, unless the chart settings are customized to use a different time zone.
Note At the device level for WAAS Express devices, only charts for supported accelerators are available. In all charts, pass-through traffic for WAAS Express devices is considered as zero.
The following TCP optimization charts are available:
The Compression Summary chart displays a bar chart depicting the percentage of traffic reduction (excluding pass-through traffic) for the top ten applications with the highest percentage of traffic reduction. Two additional tabs allow you to see the compression of the top ten applications by volume and the bottom ten applications with the lowest compression.

This chart is applicable at the device level. It is a combination chart that collects statistics for every 5 minutes from statistics infrastructure and plots the graph to represent the below information based on the statistics collected.
This section describes tables that provide information on system, device, traffic and acceleration, For information on charts that you can choose to include in a dashboard or report, see WAAS Chart Descriptions.
The following statistics details tables are available:
You can sort the tables by clicking any column heading to sort the data in that column. A small triangle appears in the heading to indicate that a column is sorted. Click the triangle to reverse the sort order in the column.
For some values, different formulas are used at the system and device levels, and these formulas are noted in the table descriptions. The terms used in the tables are:
To get the statistics at the system, location, and device group levels, the Original Inbound, Original Outbound, Optimized Inbound, Optimized Outbound, Pass-through Client, and Pass-through Server bytes of all devices are added together. The Reduction % and Effective Capacity values are calculated using added values of all devices.
This table is called the Network Traffic Summary, Device Traffic Summary, or Location Traffic Summary, depending on the context, and it displays a summary of traffic.
At the system and location levels, each row in the table displays the total traffic information for each device that is registered to the corresponding Central Manager or is in a particular location. At the device level, each row in the table displays the total traffic information for each application defined on the device. The data is described in Table 15-4 .

The ICA data for Version 4.5 WAAS devices is available in the system-level TCP Summary Report. For more information, see TCP Summary Report.
The Summary Report is a predefined report that can be used to monitor system operation. It is available at the system level. This report displays the following charts and tables by default:
The Summary Report can be customized to display the charts that you require. Use the Customize taskbar icon to select the charts that you want to be displayed in this report. Only 12 charts can be displayed in the report.
The Topology report at the system level displays a topology map that shows a graphical representation of all the connections between the WAAS devices.
The topology map uses blue squares to show connections between devices. Use the legend to the right of the grid to associate the device name with the number that appears at the top of the grid. Use the drop-down lists at the top of the window to perform the following tasks:
Click the View icon next to the WAE to view a list of peer devices for a specific WAE. The Peer List window appears, which is the same as the device level Topology report.
At the device level, the Topology report lists all the peer devices connected to a specific WAE so that you can see the relationship between devices in your WAAS network. The Peer List window displays information about each peer device involved in optimized connections with this WAE. To go to the system level Topology report, click the Topology icon in the taskbar.
If a peer device is not registered with the WAAS Central Manager, the message Unknown, this peer is not being managed by CM is displayed for the name and Unknown is displayed for the IP address.
Note The WAAS Central Manager device does not have any peers because it does not participate with any WAEs to optimize traffic. For this reason, the topology feature is not available on the WAAS Central Manager device.
The Connection Trend Report displays the connection trends of applications on a device. The following charts are included:
The Connections Statistics report displays a Connections Statistics table for the device. The table displays all the TCP connections handled by the device and corresponds to the show statistics connection EXEC mode command in WAE and the show waas connection brief command in WAAS Express.
You can choose to display a subset of connections identified by IP address and port by entering values in the Source/Destination IP Address and Source/Destination Port fields above the table and clicking Submit. To see the Connection Start Time for the active connections in appropriate time zones, you can select the time zone from the available values of CM Local Time, Device Local Time and UTC from the Show Connection Start Time drop-down list.
Note In case of a clock or timezone change in the WAE, the exact time for device timezone is reflected after the configuration synchronization cycles.
The Connection Statistics table displays the following information about each connection:
Note If the WAE is inheriting policies from a device group, the Create Class-Map button is dimmed, to prevent a user from unknowingly overriding device group policies. To create a class map, you must first override the device group policy page and then return to the Connection Statistics report.
The data in the Connections Statistics table is retrieved from the device once when you view the table for the first time.
From the Connections Statistics table, you can perform the following tasks:
The Connection Details window contains connection addresses, port information, policy information, and traffic statistics. It also displays graphs that plot real-time traffic statistics and are refreshed every two seconds.
Note In the Connection Details window, if the value for Percentage Compression is negative, the Percentage Compression and Effective Capacity values do not appear.
In some cases, the Central Manager is not able to fetch the Connections Statistics page details at the WAE device level. This happens when the WAE uses internal IP for management purpose with the Central Manager and external IP (NAT) for RPC or registration purpose with the WAAS Central Manager, and if the internal IP not reachable from the WAAS Central Manager.
The Resource Utilization report displays the following charts:
The Disks Report displays physical and logical disk information.
The report window displays the following information about each disk:
From this window, you can save all disk information details to an Excel spreadsheet by clicking the Export Table icon in the taskbar.
The AppNav report displays AppNav flow distribution information. This report is available at the AppNav Cluster level, where it shows statistics for the whole AppNav Cluster, and at the device level for AppNav Controllers (ANCs), where it shows statistics for a single ANC.
The following charts and tables are included:
At the AppNav Cluster level, the following additional controls appear in the taskbar:
Note At the AppNav Cluster level, the charts may not show data if the configuration on all ANCs in the cluster does not match. To resolve this situation, choose AppNav Clusters > cluster-name from the Central Manager menu and click the taskbar icon named Force Settings on all Devices in a Group. After about 15 minutes, the AppNav charts will display data.
Using the spreadsheet icon in the Central Manager taskbar, you can export chart values to a CSV file.
Table 15-13 provides descriptions of report column headings for exported reports. Because there are many report column headings, the table is divided into categories by types of traffic, in alphabetical order. For these heading descriptions, a time specification (for example, milliseconds) is not noted, as the time specification may change depending on the time period specified for the report (for example, hour or week).
Table 15-13 Exported Report Column Headings

Admin users can view reports scheduled by all users or the name of the report creator. Nonadmin users can view only reports scheduled by themselves.
Any changes to predefined report settings are stored separately for individual users. That is, if one user changes a predefined scheduled report, only that user sees the changes, and other users (including admin users) continue to see the report with default settings.
Reports scheduled by an external user are deleted if the maximum limit of days without a login passes and the user is deleted. For more information, see the cdm.remoteuser.deletionDaysLimit system configuration property in the “Configuring Other System Settings” chapter.
Note You cannot delete a scheduled custom report after you have scheduled it and it is in pending status. You can delete a report only after it has been generated.
Flow-monitoring applications collect traffic data that is used for application trend studies, network planning, and vendor-deployment impact studies. This section describes how to configure the flow monitoring feature on the WAE, and includes the following topics:
The NetQoS monitoring application can interoperate with the WAAS software to provide flow monitoring. To integrate this application with the WAAS software, configure the NetQoS FlowAgent module on the WAE devices. The NetQoS FlowAgent module on the WAE collects important metrics of packet flows, which are then sent across the network to the NetQoS SuperAgent. This monitoring agent analyzes the data and generates reports. For this feature to work, additional configuration is required on the NetQoS FlowAgent. (See the Example: Using NetQoS for Flow Monitoring.)
The monitoring agent comprises two modules: the console (or host) and the collector. The WAE initiates two types of connections to these two monitoring agent modules: a temporary connection to the console and a persistent connection to the collector.
Consider the following when you configure flow monitoring with NetQoS:
To configure NetQoS flow monitoring on your WAEs using the Central Manager GUI, follow these steps:
Step 1 Create a new device group for configuring flow monitoring on multiple devices by choosing Device Groups > device-group-name > Create New Device Group.
a. When you create a device group, check the Automatically assign all newly activated devices to this group check box to enable this option.
b. Add your existing WAE devices to this new device group.
Step 2 In the Device Group listing window, click the Edit icon next to the name of the flow monitoring configuration device group that you want to configure.
Step 3 Choose Configure > Monitoring > Flow Monitor. The Flow Monitor Settings for Device Group window appears.
Step 4 In the Destination IP Address field, enter the IP address of the monitoring agent console.
This configuration allows the WAE to establish a temporary connection (a control connection) to the console for the purpose of obtaining the IP address of the collector device. You must configure the collector IP address information from the console device. (See the configuration documentation for the NetQoS flow monitoring application software.)
Step 5 Check the Enable Flow Monitor check box.
Step 6 Click Submit to apply the settings to the devices in this device group.
To configure NetQoS flow monitoring on the WAE using the CLI, follow these steps:
Step 1 Register the WAE with the IP address of the monitoring agent console.
This configuration allows the WAE to establish a temporary connection (a control connection) to the console (or host) for the purpose of obtaining the IP address of the collector device. You must configure the collector IP address information from the console device. (See the configuration documentation for the NetQoS flow monitoring application software.)
Step 2 Enable flow monitoring on the WAE appliance.
Step 3 Check the configuration by using the show running-config EXEC command.
NetQoS integrates with the WAAS software by running the NetQoS FlowAgent on WAE devices. FlowAgent is a software module developed by NetQoS that resides on a WAE appliance. The FlowAgent collects metrics about the packet flows, which are then sent across the network to a NetQoS SuperAgent. The SuperAgent measures the round-trip times, server response times, and data transfer times, and then analyzes the data and generates reports.
Note When you use flow monitoring with the NetQoS SuperAgent, the flow monitor on the WAE captures optimized traffic only.
To configure flow monitoring with NetQoS, follow these steps:
Step 1 From the WAE CLI or Central Manager GUI, enter the SuperAgent Master Console IP address in the Destination IP Address field on your WAE appliances.
If you are configuring multiple WAAS devices through a device group, wait for the configuration to propagate to all the devices in the device list.
Step 2 From the NetQoS SuperAgent console, assign a WAE to a SuperAgent Aggregator (known as the collector in WAAS terminology) and configure the NetQoS networks, servers, and applications entities.
Note For information about using the NetQoS SuperAgent Master Console and configuring NetQoS SuperAgent entities, go to http://support.ca.com
NetFlow v9 is a template-based protocol developed by Cisco Systems to collect IP traffic information. The NetFlow v9 record format consists of a packet header followed by a template flowset of data flowset. A template flowset contains a description of the fields to be sent through in the data flowset. A data flowset is a collection of the data records containing flow information that is put into an export packet.
WAAS v5.3.1 and later provide the following features for Netflow v9:
To configure NetFlow v9 on your WAEs from the CLI, configure four monitoring areas:
To configure NetFlow v9 flow monitoring on the WAE using the CLI, follow these steps:
Step 1 Use the following command to create a flow record to configure which fields to collect as part of Netflow export:

Step 2 Use the following command to create the flow exporter, which includes the destination IP address and port for the Netflow:
Step 3 Use the following command to create the flow monitor and associate the flow record with the flow exporter:
If flow monitoring is configured, it is enabled for all class-maps by default. Use the following command to disable monitoring for a particular class:
In NetFlow v9, there are several fields that can be provided to the NetFlow collector. The following tables provide some examples of these fields:
