Easy Management of Numerous Alarms

After installing the U2000, you may hear a lot of alarms (including unconcerned alarms) frequently reported. You can perform the following operations to mute the U2000:

1.         Redefine alarm severities

2.         Mask unconcerned alarms

3.         Enable the U2000 to automatically acknowledge cleared alarms

4.         Enable the U2000 to automatically dump acknowledged and cleared alarms

5.         Identify engineering alarms

6.         Filter out concerned alarms

7.         Record the alarm frequency to reduce the alarm quantity

Applicable Scenarios

[Redefining Alarm Severities]

Redefine unconcerned alarms as low-severity ones while concerned alarms as high-severity ones.

[Setting an Alarm Mask Rule]

A large number of alarms may be reported during NE maintenance, testing, or deployment. You can set an alarm mask rule on the U2000 to discard unconcerned alarms or events. After being masked, the alarms or events are not saved to the U2000 alarm database.

[Setting an Automatic Alarm Acknowledgement Rule]

You can set a rule to enable the U2000 to automatically acknowledge cleared alarms and enable acknowledged and cleared current alarms to automatically change to historical alarms after a specified delay.

[Setting the Alarm Maintenance Status]

Some alarms may be generated and reported to the U2000 during NE installation, commissioning, or testing. These alarms do not need to be concerned at this phase. To identify and filter out this type of alarm, you can set the alarm maintenance status so as to quickly locate and handle important alarms.

[Creating an Alarm Filtering Template]

You can save common alarm query conditions as a template and use the template for future alarm monitoring and analysis. For example, if you do not need to browse the correlative alarms of current alarms, you can configure a template for filtering out the correlative alarms.

[Setting an Alarm Frequency Analysis Rule]

An alarm frequency analysis rule counts the number of alarms (excluding cleared alarms) generated per unit time. If the preset condition is met, a flapping alarm is generated, preventing the frequent generation and clearing of the same alarm. It is recommended that you set an alarm frequency analysis rule for alarms that are prone to flapping. For example, you can set such a rule to enable the system to generate a flapping alarm when a link disconnection event triggers three or more alarms within 1 minute.
