Handling Historical Alarms

Procedure

1. On the menu bar, choose Monitor > Alarms > Historical Alarms.
2. Perform the following operations to handle historical alarms:
   • Exporting alarms

     You can export some alarms to a file for administrators to locate and analyze problems. In the following example, alarms are exported in Google Chrome.

     

     Some Google Chrome browsers have default security policies. When you export a file, the system displays a message indicating that the file is not frequently downloaded and may contain risk factors. In this case, continue to download the file as prompted.

     1. Select one or more alarms.
     2. Click Export.

        The Save As dialog box is displayed.

     3. Select a path for saving the alarm file, enter a name for the file or use the default file name, and click Save.

        The selected alarms are exported to the specified local path.

   • Exporting all alarms

     Export all the historical alarms to a file for administrators to locate and analyze problems. In the following example, alarms are exported in Google Chrome.

     

     A maximum of 20,000 alarms can be exported at a time. You need to export alarms in batches if the total number of alarms exceeds 20,000.

     1. Click Export All.

        All the historical alarms are exported to the specified local path.

   • Searching for alarms

     Set the criteria to search for desired alarms.

     • When you select Search, you can search for alarms by alarm severity.
     • If Advanced is selected, you can search for alarms by alarm severity, type, acknowledgement status, source, and occurrence time.
   • Viewing alarms
     • Click the name of an alarm to view its details.
       1. Click the name of an alarm.

          The page showing the details about the alarm is displayed.

       2. View the basic information and recommended actions of the alarm.
       3. (Optional) In the Maintenance Experiences area, record the experiences in locating and handling the alarm to the alarm knowledge repository. This helps maintenance personnel handle the alarm quickly next time when the same fault occurs.

          You can delete the maintenance experiences.

          

          Maintenance experience is a common experience. All users can modify and delete maintenance experience.

     • You can click the number after an alarm to view the occurrence time, acknowledgement status and time, clearance status and time, and notification type of the alarm.

       According to the alarm notification type, you can determine whether the alarm is a new alarm, manually cleared alarm, or automatically cleared alarm.
