Shinken Event Handler execution required when the service state changes to CRITICAL..

[sjose1x]

A service check S1 with event_handler configurated, max_attempts is 3, check interval is 5 and retry interval is 2

When this service turns to OK - WARNING the event handler executes.., also event handler invokation continues till the max_attempts are over.
Once the max_attempts are over, and then if the service check turns to WARNING - CRITICAL then the event handler did not get triggered..

Is it possible to configure event handler to get executed whenever the service turns to CRITICAL. (OK - CRITICAL OR WARNING - CRITICAL) ..?

That is regardless of first it turns to WARNING and then it becomes CRITICAL or initial problem state itself is CRITICAL
