Handling Current Alarms

You can use the alarm acknowledgement mechanism to distinguish handled alarms from alarms that are not handled. In addition, you can add alarm maintenance experiences for each alarm, facilitating system maintenance and sharing experiences.

Procedure

On the menu bar, choose Monitor > Alarms > Current Alarms.
Perform the following operations to handle current alarms:
- Acknowledging alarms
  
  You can use the alarm acknowledgement mechanism to distinguish handled alarms from alarms that are not handled.
  1. Select one or more alarms whose Status is Unacknowledged.
  2. Click Acknowledged.
    In the Warning dialog box that is displayed, read the content of the dialog box carefully and select I have read and understood the consequences associated with performing this operation.
  3. Click OK.
    The Information dialog box is displayed.
  4. Click OK.
    Status of selected alarms changes to Acknowledged.
    
    After receiving the alarm acknowledgement command, eReplication records the operator, refreshes alarm information, and updates the alarm in the database.
- Canceling alarm acknowledgement
  Cancel the acknowledgement of acknowledged alarms.
  1. Select one or more alarms whose Status is Acknowledged.
  2. Click Unacknowledged.
    In the Warning dialog box that is displayed, read the content of the dialog box carefully and select I have read and understood the consequences associated with performing this operation.
  3. Click OK.
    The Information dialog box is displayed.
  4. Click OK.
    Status of selected alarms changes to Unacknowledged.
- Clearing alarms
  
  In some special situations, for example, the communication between the NMS and an NE is interrupted, cleared alarms may be lost. In such a condition, these alarms cannot be cleared automatically if the NE does not support the alarm verification function. To solve this problem, eReplication supports the ability to manually clear alarms. In other words, manually change the status of the uncleared alarms to cleared. Some alarms cannot be manually cleared.
  1. Select one or more alarms whose Status is Acknowledged.
  2. Click Clear.
    In the Warning dialog box that is displayed, read the content of the dialog box carefully and select I have read and understood the consequences associated with performing this operation.
  3. Click OK.
    The Information dialog box is displayed.
  4. Click OK.
    All the selected alarms are removed from the current alarm list to the historical alarm list. The NMS records the operator and time, refreshes alarm information, and updates the alarm database.
- 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 Internet Explorer.
  
  If a default security policy is configured for Internet Explorer, a message indicating "To help protect you security, Internet Explorer blocked this site from downloading file to your computer" is displayed when you export alarms. You need to right-click the message and choose Download File from the shortcut menu that is displayed. After the eReplication page is refreshed, export alarms again.
  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
  You can export all the current 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 current alarms are exported to the specified local path.
- Refreshing alarms
  You can select a refresh policy from the drop-down list. The policy can be Refresh every 15 seconds, Refresh every 30 seconds, Refresh every 60 seconds, or Stop refreshing.
  
  Refresh every 15 seconds is selected by default. This means that the NMS performs a round robin every 15 seconds. Once a new alarm occurs, the NMS will refresh it to the current alarm list. Or you can click in the upper right corner of the Current Alarms page to refresh the current alarm list.
- Searching for alarms
  Set the criteria to search for desired alarms. 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.
