Viewing the Alarm List

The alarm list provides information about all alarms in the MRS cluster. Examples of alarms include host faults, disk usage exceeding the threshold, and component abnormalities.

In Alarms on the MRS management console, you can only view basic information about alarms that are not cleared in MRS Manager. If you want to view alarm details or manage alarms, log in to MRS Manager. For details, see Alarm Management.

Alarms are listed in chronological order by default in the alarm list, with the most recent alarms displayed at the top.

Table 1 describes alarm parameters.
