The NSX Application Platform sends alarm notifications to alert you about specific events that might require your immediate attention. You can monitor alarms that are active for the NSX Application Platform using the NSX Manager UI.

The system automatically resolves some of the alarms it detects. To manage the alarms that require your attention, use the following steps.


To manage the alarms, you must have Enterprise Admin privileges.


  1. From your browser, log in with Enterprise Admin privileges to an NSX Manager at https://<nsx-manager-ip-address>.
  2. Navigate to System > NSX Application Platform.
  3. To see the total number of alarms detected, locate the Overall Alarms section in the upper-right side of the NSX Application Platform pane.
    If alarms exist, the displayed number link indicates the total number of detected alarms in the resources the NSX Application Platform uses or the core services it supports.
  4. (Optional) To view the open alarms specific to the resources or core services, click the Resources or the Core Services tab on the left side of the pane.
    Alarm links also appear for each individual resource or core service that has an existing open alarm.
  5. Review the active alarms.
    1. To view the list of the active alarms, click the alarm links provided in the UI.
      The system displays the corresponding dialog box depending on which alarm link you click. For example, the Resources Alarms dialog box displays only the open alarms detected in the resources that the NSX Application Platform uses.
    2. To display the details for an alarm, expand the row for the alarm in the dialog box.
      You can review the description of the alarm type, severity level, times it was reported, and the recommended action to resolve the alarm.
    3. To close the dialog box, click Close.
  6. To take one of the available actions you can apply to an Open alarm, navigate to Home > Alarms page.
    1. To narrow the list of alarms displayed, use the filter for the NSX Application Platform Communication and NSX Application Platform Health features.
    2. Locate the alarm that you want to manage and select the check box in the leftmost column.
    3. Click Actions menu icon and select one of the following actions that you want to apply to the selected alarm.
      You can move an alarm to one of the following states depending on the actions allowed for the current alarm state.
      Action Description
      Open The alarm is placed in an active, but unacknowledged state.
      Acknowledge The alarm is acknowledged, but it remains open. Its Last Reported Time value continues to be updated until you move the alarm to another state.
      Suppress When you suppress an alarm, the system prompts you to specify how many hours you want the alarm suppressed. If after the specified suppression time is reached and the alarm condition remains the same, the alarm state is returned to the Open status. If during the suppression period the alarm condition is resolved, the system automatically changes the alarm state to Resolved.
      Resolve You can manually resolve an alarm. Once you manually resolved an alarm, you can no longer change its state. If you resolve an alarm manually, but the problem persists, the system opens another similar alarm. The system continuously monitors the NSX Application Platform and can auto-resolve an alarm.

      The system updates the Alarm State value for the alarm.
