Viewing the Alarm List
======================

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.

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 :ref:`Viewing and Manually Clearing an Alarm <mrs_01_0113>`.

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

:ref:`Table 1 <en-us_topic_0040980162__table5924273517010>` describes various fields in an alarm.

Additionally, this type of alarms also occurs when an instance is faulty, a job executed successfully, or a job failed to be executed. |

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. |
