Viewing the Alarm List

Updated at:Sep 29, 2020 GMT+08:00

The alarm list displays all alarms in the MRS cluster. The MRS page displays the alarms that need to be handled in a timely manner and the events. The alarms are classified into the following levels:

  • Critical: indicates alarms reporting errors that affect cluster running, such as unavailable cluster services, node faults, data inconsistency between the active and standby GaussDB databases, and abnormal LdapServer data synchronization. You need to check the cluster status based on the alarms and rectify the faults in a timely manner.
  • Major: indicates alarms reporting errors that affect some cluster functions, including process faults, periodic backup task failures, and abnormal key file permissions. Check the objects for which the alarms are generated based on the alarms and clear the alarms in a timely manner.
  • Minor: indicates alarms reporting errors that do not affect major functions of the current cluster, including alarms indicating that the certificate file is about to expire, audit logs fail to be dumped, and the license file is about to expire.
  • Suggestion: indicates an alarm of the lowest severity. It is used for information display or prompt and indicates that an event occurs in the scenarios when you stop a service, delete a service, stop an instance, delete an instance, delete a node, restart a service, restart an instance, perform an active/standby switchover for MRS Manager, scale in a host, or restore an instance. Additionally, this type of alarms also occurs when an instance is faulty, a job executed successfully, or a job failed to be executed.

On the MRS management console, you can only query basic information about uncleared MRS alarms on the Alarms tab page. For details about how to view alarm details or manage alarms, see Viewing and Manually Clearing an Alarm.

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