7.4.8 Working with Alarms

 



 

Alarms are generated when a failure or fault is detected in the network devices. The events generated are converted to alarms based on its significance and they are simply messages calling for operator's/administrator's attention.

 

Viewing Alarms

 

To view the Alarms view

  1. Click the Fault Management module tab in the Web Client. By default the Events view is displayed.

  2. Click Alarms on the left-side Fault Management tree.

The Alarms view is displayed on the right-side frame in a table format. This table format is called Alarms List View.

 

Customizing Alarms Per Page Count

 

By default, 25 alarms are shown per page in the Alarms List View.

 

To view more number of alarms per page

 

In the Alarms List View, choose a value from entries per page combo box.

 

Browsing the Alarms

 

To browse through the list of alarms, use the First, Previous, Next, and Last navigation facility placed above the Alarms List View. Clicking navigation icons display the desired page, such as the first page, previous page, next page, and the last page of Alarms List View.

 

Alarm Summary

 

To view the total number of alarms generated in Web NMS,  Alarm Summary is provided at the bottom left corner in the Web Client pages. It is a table listing the total alarm count on module/category basis.

Picking Up / Unpicking the Alarm

 

Pick Up is a mechanism that helps in assigning a particular alarm/fault of a device to a work group or user. This ensures that all problems are picked up and work is not duplicated. It is also possible to Unpick an Alarm which has already been assigned to a user or work group.

 

An alarm annotation entry will be entered with the name of the user who has picked up / unpicked the alarm and the time it was performed.

 

To pick up an alarm

    1. In the Alarm Properties view, click Pickup link. If you are in the Alarms List View, then select the check box of the alarm which you need to pick up and click Pickup. To pick up multiple alarms, select all those alarms' check boxes and then click Pickup.

    2. An Assign Alarm page is displayed. Enter the user name or group name to whom you need to assign the alarm(s) in Assign To field and click Assign.


Note

This Assign Alarm page is displayed only if you have the administrative permission to assign alarms to others. If you do not have the permission, then on clicking Pickup, the alarms are assigned to your user name.

 

To unpick an alarm

    1. In the Alarm Properties view, click Unpick link. If you are in the Alarms List View, then select the check box of the alarm which you need to unpick and click Unpick. To unpick multiple alarms, choose all those alarms' check boxes and then click Unpick.

Adding Comments to the Alarm

 

It is important to track any action you have taken to fix an alarm or any new information you have gathered about the alarm. Annotate option can be used to add notes to an alarm for future reference. For example, the solution for a problem resolved by you can be entered by using the Annotate option. This enables other users to solve the same problem with less effort, by just reading the annotation.

 

To add comments to alarm

    1. In the Alarm Properties view, click Annotate link. An Annotate form is displayed.

    2. Enter your comments in the Message field.

    3. Click Annotate.

Viewing Alarm Annotation

 

To view all the user-defined annotations along with the time of annotation, click Annotation & History in the Alarm Properties view.

 

Viewing Alarm History

 

The history of the Alarms give the complete information on the status of the Alarms, such as when they are added / updated. For example, when a critical alarm is generated, the Alarms view displays the current status of the alarm. If the problem has been fixed, an alarm with clear severity will update the one with critical severity.

 

By clicking the Annotation & History in Alarm Properties view, you can view the history of that alarm, from first alarm to the latest one, i.e., the time at which the problem was created and fixed along with the timings of alarm generation and severity change.

 

Viewing both Annotation and History

 

The Merge history option in Alarm Properties view enables you to view the annotations and history together in an order of precedence based on time. To get back to the separate views of annotation and history, click Annotation & History.

 

Viewing Related Alarms

 

To view other alarms generated for the same network element, click Related Alarms in the Alarm Properties view.

Working with Alarm Views

 

The alarms in the Alarms List View could be numerous and hence difficulty arises in identifying alarms of your interest. A Search can be performed to locate the alarms you are looking for. But if you are looking for a lot of alarms that satisfy a certain set of criteria, then use the Add Child View, Edit View Criteria, and Remove View options. This helps you to get the alarms of your interest alone in that custom view, instead of doing a search every time.

 

A Child View that you create is a subset of data that satisfy a given criteria from a larger collection. By creating new views, you will easily filter the desired data that is displayed and sort through large amount of alarms data.

 

Adding a New View

 

You can add/create a new view by specifying various criteria and providing a name for the view. The views you create enable you to quickly monitor the devices of your concern. You can create multiple views that display a variety of information.

 

For example, you can create a new view named MasterAlarms which shows only alarms in a particular network. Within this MasterAlarms view, you can create more views, say MA1, MA2, etc. MA1 can have a different set of criteria, say only critical alarms in that particular network. Deleting MasterAlarms deletes its child views (MA1, MA2, etc.,) as well.

 

To add a view

    1. In the Alarms List View, click Add Child View. The options to create the view are displayed.

    2. Enter the required criteria in the fields available. For information on each of the fields in this form, refer to Custom View Properties in Appendix. Wildcard characters can be used to specify the matching criteria. For information on the wildcard characters that can used, refer to Tips and Tricks in Appendix. If none of the fields is filled in (except for Custom View Name), then by default all the fields are set with the value 'all'.

    3. On configuring the criteria, click Submit.

On performing this, a new child node with the configured view name is created under Fault Management > Alarms tree node. Following the same procedure, more custom views can be added.

 

Modifying a View

 

A view can be modified to change the criteria that were set or to rename the view.

 

To modify a view

    1. In the Alarms List View, click the desired view on the Fault Management > Alarms tree.

    2. Click Edit View Criteria. The custom view form is displayed with the configurations (made at the time of creation or last modification). For information on each of the fields in this form, refer to Custom View Properties in Appendix. Wildcard characters can be used to specify the matching criteria. For information on the wildcard characters that can used, refer to Tips and Tricks in Appendix.

    3. Make the required changes and click Submit.

On performing this, the view is refreshed to provide you with the new view based on modified criteria.

 

Removing a View

 

A view can be deleted from the Alarms List View when you do not require it anymore.

 


Note

The parent node Alarms cannot be deleted from the Fault Management tree. Only those views created under this parent node can be deleted.

 

To remove a view

  1. In the Alarms List View, click the desired view on the Fault Management > Alarms tree.

  2. Click Remove View. A confirmation is asked for. Click Yes to remove the view.

Working with Audio Notifications

 

When alarms are received by the client, an audio notification can be triggered based on the severity of the alarm. All users configured for the notification will be able to hear the respective audio whenever alarms are received by the client. The audio notification for alarms will be user specific i.e. each user can associate different audio file for different severities. For configuration please refer to the Developer Guide.

 

When the audio playback is configured for infinity, the stop icon will appear next to the Failure Object column. You can click on the stop icon    to stop the audio.
