Several settings in an alarm definition can be customized. From the Alarm Definitions page, you can enable or disable an alarm, configure if an event (when true) creates an alarm, create an SNMP trap, set alarm threshold, and set alarm sensitivity. From the Alarm Definitions page, you can enable or disable detection of an alarm, whether an alarm is reported in the API/user interface, and whether a SNMP trap is emitted when an alarm is detected or resolved.
Setting | Control Type | Description |
---|---|---|
Enabled | Toggle | Enables or disables detection of the alarm. |
Create Alarms | Toggle | Enables or disables whether the alarm is reported in the API/UI. |
Create SNMP Traps | Toggle | Enables or disables whether an SNMP trap is emitted when an alarm is detected or resolved. |
Threshold | Numerical value | Configures the threshold for triggering the event. This value determines if a single sample is true and triggers an event.
|
Sensitivity (%) | Numerical value (percentage) | Configures the sensitivity for triggering the alarm. Sensitivity defines the conditions that trigger an alarm. (The sample size is internally defined and cannot be modified.) If the sample size is ten and sensitivity is set to 80%, then eight or more occurrences in the sample of ten raises the alarms. See the NSX-T Data Center REST API documentation. |
