Viewing and Manually Clearing an Alarm

Updated at: Mar 25, 2021 GMT+08:00


You can view and clear alarms on MRS Manager.

Generally, the system automatically clears an alarm when the fault is rectified. If the fault has been rectified and the alarm cannot be automatically cleared, you can manually clear the alarm.

You can view the latest 100,000 alarms (including uncleared, manually cleared, and automatically cleared alarms) on MRS Manager. If the number of cleared alarms exceeds 100,000 and is about to reach 110,000, the system automatically dumps the earliest 10,000 cleared alarms to ${BIGDATA_HOME}/OMSV100R001C00x8664/workspace/data on the active management node. A directory is automatically generated when alarms are dumped for the first time.

Set an automatic refresh interval or click for an immediate refresh.

  1. Click Advanced Search. In the displayed alarm search area, set search criteria and click Search to view the information about specified alarms. Click Reset to clear the search criteria.

    You can set the Start Time and End Time to specify the time range. You can search for alarms generated within the time range.

    Handle the alarm by referring to Alarm Reference. If the alarms in some scenarios are generated due to other cloud services that MRS depends on, you need to contact maintenance personnel of the corresponding cloud services.

  2. If the alarm needs to be manually cleared after errors are rectified, click Clear Alarm.

    If multiple alarms have been handled, you can select one or more alarms to be cleared and click Clear Alarm to clear the alarms in batches. A maximum of 300 alarms can be cleared in each batch.
