Viewing Alarms

Viewing Alarms

In the alarm area, you can view current performance threshold alarms, device offline alarms, and historical alarms. These alarms help you diagnose problems in storage systems.


By default, historical alarms are stored for 90 days. You can set the number of alarm retention days in Alarm Dump. After this is set, only data recorded recently by the database will be retained and the rest will be dumped. By default, the system alarm dump file is stored in SystemReporter installation directory\Runtime\LegoRuntime\datastorage\alarm on the SystemReporter server.

You can use OceanStor DeviceManager to view threshold alarms generated on SystemReporter. For details, see Checking Alarm Information of a Storage System.
