However, you must not configure any thresholds if you have selected All, as the threshold value for measurement types vary. You must always set the threshold values separately for each measurement type.
Enable Collection	Select the check box to enable collection of the selected Measurement Type.
Enable Reporting	Select the check box to enable reporting for the selected Measurement Type.
Generate Incident	Select the check box to generate incident in the incident inventory.
Threshold Severity	Indicates the severity of the incident that is generated during a threshold violation. You can select one of the following types: Critical: The NNM iSPI for IP Telephony generates a (MonitoredAttributeThresholdBreachCrirtical) incident. Major: The NNM iSPI for IP Telephony generates a (MonitoredAttributeThresholdBreachMajor) incident. Minor: The NNM iSPI for IP Telephony generates a (MonitoredAttributeThresholdBreachMinor) incident. Warning: The NNM iSPI for IP Telephony generates a (MonitoredAttributeThresholdBreachWarning) incident. The NNM iSPI for IP Telephony generates the MonitoredAttributeThresholdBreachClear incident after you resolve the cause for the generation of any of the four incidents.
Lower Base	Specify the lower base value for the Session Agents type threshold.
% Lower Deviation	Specify the acceptable percentage of deviation from the lower base threshold value before generating an incident.
Abs Lower Deviation	Specify the acceptable absolute value of deviation for the lower base threshold value before generating the incident.
Lower Trigger Count	Specify the number of times the threshold deviation should be permitted for the lower base before generating the incident. Specifying the trigger count is mandatory for generating incidents.
Higher Base	Specify the higher base value for the Session Agents type threshold.
% Higher Deviation	Specify the acceptable percentage of deviation from the higher base threshold value before generating an incident.
Abs Higher Deviation	Specify the acceptable absolute value of deviation for the higher base threshold value before generating the incident.
Higher Trigger Count	Specify the number of times the threshold deviation should be permitted for the higher base before generating the incident. Specifying the trigger count is mandatory for generating incidents.
