Associating Alarms and Actions for Network devices

With the OpManager Network Monitoring Connector, you can view alarms from your OpManager network devices in Applications Manager and associate actions to Opmanager attributes.

Alarms:

Once you have imported all your devices from OpManager, go to the Alarms Tab to view all the alarms configured in Applications Manager along with their severity, type, date and the technician to whom the alarm is assigned. You can filter and sort through the alarms by clicking on the parameter type at the top of the table.

You can view all alarms or filter the Critical , Warning  and Clear  alarms. You can also filter alarms by:

  • Alarm Actions
  • Selected Time
  • Selected Monitor Group
  • Selected Monitor Type

You can search through alarms by clicking the search button  at the top of the alarms table. Click here to know more about the Alarms Tab.

Actions:

You can trigger corrective actions to OpManager attributes, once you have imported your network devices, such as sending e-mail, SMS, trap, and executing a command, to notify you of the alarms generated while monitoring the network devices. To trigger such corrective actions, you should have defined the action, which can then be associated with an attribute. Click here to learn more about how to define actions.

Note: You cannot create or associate thresholds for Opmanager attributes.

Limitations

  • If OpManager is integrated with the Admin server, integration in all the Managed servers will be restricted and vice versa.
  • If OpManager is integrated with both Admin and Managed server, OpManager's data collection in the Managed servers will be disabled. No OpManager data from the Managed servers will be displayed in both Admin and Managed server's UI. The user will be able to access the delete option for the Managed server's OpManager. (Note: Integrating OpManager with both Admin and Managed server, is not recommended).
  • In the above case, if OpManager integrated with Admin server is deleted, then OpManager in Managed server's data collection will be enabled and all the data related to Managed server's OpManager will be displayed in both Admin and Managed server's UI.
