Whereas merely acknowledging most alarms does not clear them, some alarm conditions are set up to be self-clearing when you acknowledge them. For example, if you remove a hard disk drive, it generates an alarm; once you’ve replaced it and it has finished rebuilding itself, the alarm clears.
Alarms have one of four severity levels: Critical,
Major,
Minor, and
Warning. Only
Critical and
Major alarms are service-affecting.
The appliance can raise alarms based on issues with tunnels, software, equipment, and Threshold Crossing Alerts (TCAs). The latter are visible on the appliance but managed by the Orchestrator.
Although Appliance Manager (the WebUI) doesn’t display Alarm Type ID (Hex) codes, the data is available for applications that can do their own filtering, such as SNMP.
