Monitoring a NetScaler Application

Oct 19, 2016

After you customize the AppExpert application, you can view application statistics to make sure that the application and all its entities are working correctly. You can also use the Application Visualizer to monitor statistics associated with certain entities such as policies and virtual servers.

You can also view the hit counters for various entities at regular intervals to make sure that counters are being updated.

Viewing Application Statistics

Updated: 2013-08-30

In the Applications node, you can select an application and view the Statistics page for the application. On the Statistics page, you can monitor the health and states of public endpoints and application units, and view the following statistical information:

  • Requests and responses per second for each of the public endpoints and application units.
  • Bytes per second, at each endpoint, for incoming and outgoing traffic.
  • Application unit hit counters and the number of client and server connections for each application unit.
  • Statistics for the services that are bound to the application units.

On the Statistics page, you can also view CPU usage, memory usage, and system logs.

To view statistics for an application

  1. Navigate to AppExpert > Applications.
  2. In the details pane, click the application for which you want to view statistics, and then click Statistics.

Monitoring an Application by Using the Application Visualizer

Updated: 2013-08-30

You can use the Application Visualizer to monitor the number of requests received per second at a given point in time by the vservers and the number of hits per second at a given point in time for Rewrite, Responder, and Cache policies.

To view statistical information for vservers, Rewrite policies, Responder policies, and Cache policies in the Visualizer

  1. Navigate to AppExpert > Applications.
  2. In the details pane, select the application for which you want to view statistical information, and then click Visualizer.
  3. In the Application Visualizer window, do the following:
    • To view the statistics, click Show Stats.

      The statistical information is displayed on the respective nodes in the Visualizer. This information is not updated in real time and has to be refreshed manually.

    • To refresh the statistical information, click Refresh Stats.

Viewing Hits

Updated: 2013-08-30

The hit counters that are provided for various AppExpert application entities enable you to monitor the functioning of public endpoints and application units. For an application, the Hits dialog box displays the total number of requests received by each configured public endpoint. For an application unit, the Hits dialog box displays the number of requests that the application unit processed from each of the public endpoints and the total hit count. For instructions on viewing hit counters, see "Verifying and Testing the Configuration."
