Resolving dashboard alerts

The Alerts and Description column in the application table of the High Availability dashboard marks application alerts with the alert (!) icon. This occurs in the following cases:

  • Stale entries: Stale entries occur either due to a system (virtual machine) issues or connectivity issues. When this occurs, the system fails to send application heartbeats to the dashboard. If the system fails to send the heartbeat for two consecutive heartbeat intervals, the dashboard displays the alert icon.

    Note:

    You can filter stale entries using the Search option and searching with the string "stale".

  • Application faults: Application faults may occur due to reasons beyond Cluster Server (VCS) control, such as storage failure. In such cases, you must investigate and appropriately resolve the issue, and then clear the Faulted status of the application. To view only application fault alerts, in the Alerts and Description column, click the Hide Old Entries check box.

    Note:

    It is important that you fix application faults, and then clear the Fault status. Else, the VCS cannot failover applications to the faulted system, and application availability may be compromised. For more information, See To clear Fault state.
