Alarms information is displayed in several locations within the NSX Manager interface. Alarm and event information is also included with other notifications in the Notifications drop-down menu in the title bar.

An alarm can be in one of the following states:
State Description
Open Alarm is in an active, unacknowledged state.
Acknowledged Alarm has been acknowledged by a user. The alarm remains open but no longer appears in the NSX Manager notifications.
Suppressed Status reporting for this alarm has been disabled by the user for a user-specified duration.
Resolved Alarm has been resolved, whether by the system or through user action. The alarm will continue to appear in the alarm table in the Resolved state for up to eight days, after which it automatically deletes. (The system may delete resolved alarms earlier to accommodate resource needs.)
Note: If a user changes an alarm state to Resolved but the condition that triggered the alarm is not resolved, a new alarm instance will be instantiated. Also, an event may be resolved for several minutes before the reported state updates in the interface.
Note: The following steps show how to view alarms from the Home page. However, you can also view alarms from other pages, such as the Tier-0, Tier-1, and Load Balancing pages, among others. See the Alarms columns in the tables on these pages.


  1. Navigate to the Home page and click Alarms.
    Note: A red exclamation mark ( !) next to the Alarms panel label indicates at least one open alarm with a severity of Critical. .
    The Alarms panel appears, displaying along the top graphic dashboards such as Active Alarms, Top Features with the Most Alarms, and Top Events by Occurrence. Below the dashboards is a sortable, filterable list of the current alarms. The table details the following information about each active alarm:
    • Feature affected
    • Event Type
    • Node
    • Entity
    • Severity (Critical, High, Medium)
    • Last Reported Time
    • Alarm State (Open, Suppressed, Resolved, Acknowledged)

    Each row in the Alarms table can be expanded to show more details.

  2. Filter the results displayed in the dashboards by clicking the funnel icon in the upper-right corner of the dashboards.
    You can filter by the last 24 hours, last 48 hours, or custom time range, or all open alarms.
  3. Filter the results displayed in the table by clicking the filter text box above the table.
    You are prompted to specify a filter: Alarm State, Description, Entity Name, Entity Type, Event Type, Node, and so on.
