Application Delivery Management

Display event severities and SNMP trap details

When you create an event and its settings in NetScaler Application Delivery Management (ADM), you can view the event immediately on the Event Summary page. Similarly, you can view and monitor the health, up time, models, and the versions of all Citrix Application Delivery Controller (ADC) instances added to your NetScaler ADM server in minute detail on the Infrastructure Dashboard.

On the Infrastructure dashboard, you can now mask irrelevant values so that you can more easily view and monitor information such as event by severities, health, up time, models, and version of NetScaler instances in minute detail.

For example, events with a Critical severity level might occur rarely. However, when these critical events do occur on your network, you might want to further investigate, troubleshoot, and monitor where and when the event occurred. If you select all severity levels except Critical, the graph displays only the occurrences of critical events. Also, by clicking the graph, you are taken to the Severity based events page, where you can see all the details regarding when a critical event occurred for the duration that you’ve selected: the instance source, the date, category, and message notification sent when the critical event occurred.

Similarly, you can view the health of a NetScaler VPX instance on the Dashboard. You can mask the time during which the instance was up and running, and display only the times the instance was out of service. By clicking on the graph, you are taken to that instance’s page, where the out of service filter is already applied, and see details such as host name, the number of HTTP requests it received per second, CPU usage, and so on. You can also select the instance and see the particular Citrix instance’s dashboard for more details.

To select specific events by severity in NetScaler ADM:

  1. Log on to NetScaler ADM, using your administrator credentials.

  2. Navigate to Infrastructure > Dashboard.

    Or,

    Navigate to Infrastructure > Events > Reports.

  3. From the menu in the upper-right corner of the page, select the duration for which you want to see events by severity.

  4. The Events by Severity donut chart displays a visual representation of all the events by their severity. Different types of events are represented as different colored sections, and the length of each section corresponds to the total number of events of that type of severity.

  5. You can click each section on the donut chart to display the corresponding Severity based events page, which shows the following details for the selected severity for the selected duration:

    • Instance Source

    • Data of the event

    • Category of events generated by the NetScaler instance

    • Message notification sent

    Note

    Below the donut chart you can see a list of severities that are represented in the chart. By default, a donut chart displays all events of all severity types, and therefore all severity types in the list are highlighted. You can toggle the severity types to more easily view and monitor your chosen severity.

To view NetScaler SNMP trap details on NetScaler ADM:

You can now view the details of each SNMP trap received from its managed NetScaler instances on the NetScaler ADM server on the Event Settings page. Navigate to Infrastructure > Events > Event Settings. For a specific trap received from your instance, you can view the following details in tabular format:

  • Category - Specifies the category of the instance to which the event belongs.

  • Severity - The severity of the event is indicated by colors and its severity type.

  • Description - Specifies the messages associated with the event.

For example, an event with the trap category monRespTimeoutBelowThresh, the description of the trap is displayed as “This trap is sent when the response timeout for a monitor probe comes back to normal, less than the threshold set.”
