Object Configuration Client: The Understanding 37
3-5-1 EMS Alerts
OVNM always generates EMS alerts in response to threshold violations. EMS alerts can be configured using the
Alert tab page in the Actions dialog box
Figure 3-8 OCC Actions Dialog Box Alert Tab Page
The Exception section of the Alert tab allows you to adjust the initial violation, repeat, and escalation event
messages. The Severity box allows you to set the internal OVNM severity levels as Critical, Major, Minor, or
Warning for the violation messages generated in response to the threshold violations.
NOTE:
Critical is the default severity level.
Severity is shown in the EMS message. This value also dictates what severity will be displayed in ObjectMap
and ObjectStats. Note that the severity on this panel does not affect the severity COLOR shown in Console. That
value is based on the value in the eEvents panel. You must be aware of the value in the Tools, Options, Keep,
and Severity in the Sync option. Based on how that is set, changes to this field may or may not be automatically
transferred to the Violation Severity field in the eEvents panel.
You determine how frequently the Exception Event should be generated using the Repeat Every box. The default
value is 9 minutes, but the unit can be changed to seconds or hours and the required frequency value can be
entered as desired, from 00 to 59. Entering a value of 00 allows only a single exception Event to be
generated. The polling interval specified in the Schedule dialog box determines how often OVNM checks the
object state when the object is in the normal state.
The Repeat Every interval determines how often the violation message is generated. The object will always be
checked based on the polling interval. So if the polling interval is 5 minutes and the Repeat Every interval is 15
minutes, the object will be polled every 5 minutes regardless of its current state (normal or in violation). However,
OVNM will only report it as in violation, once every 15 minutes. As soon as it determines it is back to normal, it
will generate a ‘back to normal’ EMS message. This feature is not currently available for EMS-driven thresholds.
Repeat messages are not generated until the Repeat Every interval is exceeded, so it is recommended that this
value be a multiple of the polling interval.
The selection of the Escalate check box determines when the first Escalation Event is generated after the initial
violation, by specifying data in the Log Escalation Event After box. Once Escalation Events are being generated
for a violation, Exception Events are no longer generated. The default value is 30 minutes, but the unit can be
changed to seconds or hours and the required frequency value can also be specified, from 01 to 59. This must
be a value that is greater than the Poll Interval and Repeat Every values. This feature is not currently available for
EMS-driven thresholds.
