Cisco Cisco Unified Operations Manager 8.5 White Paper

Page 44 of 70

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 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

●

cenAlarmType
