View Active Alarms Using HorizonΒΆ

The StarlingX Horizon Web interface provides a page for viewing active alarms.

Alarms are fault conditions that have a state; they are set and cleared by the system as a result of monitoring and detecting a change in a fault condition. Active alarms are alarms that are in the set condition. Active alarms typically require user action to be cleared, for example, replacing a faulty cable, or removing files from a nearly full filesystem, etc.


For data networks and worker host data interfaces, you can also use the Data Network Topology view to monitor active alarms.


  1. Select Admin > Fault Management > Active Alarms in the left pane.

    The currently Active Alarms are displayed in a table, by default sorted by severity with the most critical alarms at the top. A color-coded summary count of active alarms is shown at the top of the active alarm tab as well.

    You can change the sorting of entries by clicking on the column titles. For example, to sort the table by timestamp severity, click Timestamp. The entries are re-sorted by timestamp.

    Suppressed alarms are excluded by default from the table. Suppressed alarms can be included or excluded in the table with the Show Suppressed and Hide Suppressed filter buttons at the top right of the table. The suppression filter buttons are only shown when one or more alarms are suppressed.

    The Suppression Status column is only shown in the table when the Show Suppressed filter button is selected.

  2. Click the Alarm ID of an alarm entry in the table to display the details of the alarm.
