Generate an event

You can use the nzevent generate command to trigger an event for the event manager. If the event matches a current event rule, the system takes the action that is defined by the event rule.

You might generate events for the following cases:

To simulate a system event to test an event rule.
To add new events because the system is not generating events for conditions for which you would like notification.

If the event that you want to generate has a restriction, specify the arguments that would trigger the restriction by using the -eventArgs option.

Note: Make sure that any restriction argument in the -eventArgs string does not contain " " as input, as it might cause failure in event generation with appropriate error code.

For example, if a runaway query event has a restriction that the duration of the query must be greater than 30 seconds, use a command similar to the following to ensure that a generated event is triggered:

nzevent generate -eventtype runawayquery -eventArgs 'duration=50'

In this example, the duration meets the event criteria (greater than 30) and the event is triggered. If you do not specify a value for a restriction argument in the -eventArgs string, the command uses default values for the arguments. In this example, duration has a default of 0, so the event would not be triggered since it did not meet the event criteria.

To generate an event for a system state change:

nzevent generate -eventType sysStateChanged 
-eventArgs 'previousState=online, currentState=paused'
