When you stop monitoring a device - changing its monitored state to False - Operations Manager no longer polls that
device for information. Subsequent events (including traps) are ignored and no longer processed.
Notification Services
The customization that is available for the northbound notification is extensive. If there is a messaging gateway to
the paging system, e-page subscriptions can also be set up.
Most large enterprises have their own domain managers already running in their management systems. Therefore,
the SNMP traps generated by Operations Manager are helpful in integrating Operations Manager with other
managers such as Cisco Info Center, HP OpenView Network Node Manager (NNM), or Tivoli Netview.
The email and e-page notification mechanisms provide additional ways of informing network operations personnel
about the alerts in their network. This helps ensure that network personnel do not have to monitor the real-time fault
view throughout the day.
Event Sets
Operations Manager sends notifications based on violation of thresholds as defined in Polling and Thresholds
(Administration > Polling and Thresholds). Various attributes are constantly polled from all the devices monitored
by Operations Manager. Event sets allow you to selectively pick the events of interest and then associate those
events to a particular list of devices.
This feature is useful in situations where the support for devices, or device types, or expertise is split across multiple
departments or personnel.
Notification Criteria
Notification criteria allow you to set up notifications based on devices or service quality parameters. When setting up
email notifications, make sure the following are taken care of in the Operations Manager server:
●
Port 25 is open for the email notification
●
If VirusScan is installed, go to Virus Scan > Properties > Blocking and make sure Block the connection is
left unchecked
Event Customization
Change the default event titles to suit the deployed environment. You can also change the severity level on the
event. Several customization features are available for setting up the northbound notification.
CISCO-EPM-NOTIFICATION-MIB
CISCO-EPM-NOTIFICATION-MIB is specifically defined to carry details of events generated by Operations Manager.
This MIB needs to be compiled into the manager of managers to decord [[NOTE: What should the preceding word
be? record? decode?]] the SNMP trap received from Operations Manager.
The MIB description covers in detail what each attribute carries. See the online help for information on attributes and
possible values (where applicable). Every SNMP Trap PDU generated from Operations Manager contains the
following attributes:
●
cenAlarmVersion,
●
cenAlarmTimestamp,
●
cenAlarmUpdatedTimestamp,
●
cenAlarmInstanceID,
●
cenAlarmStatus,
●
cenAlarmStatusDefinition,
