Hi

Is there any way I can get a sensu handler to run irrespective of the check output status and not only when there is a state change?

However, I DO NOT want to declare the check to be a metric.

Can this be done using a mutator by changing the status code of the check output in the event data?

Please advise.

Thanks

Pawan

Hello,

You could have the check plugin produce a non-zero exit status, perhaps \>= 3, which would cause every result to translate to an event to be handled. Why not declare the check to be a metric?

Hi

I’m looking to integrate Sensu and Flapjack and would want all check output data irrespective of the status to be sent to the handler. Thats why I dont want to declare it as a metric.

I’m using the handler to process the event and write into Redis of Flapjack which picks it up for notification.(I have already succeeded in doing this).

Cheers

Pawan

Declaring a check to be a metric just causes every result to translate to an event, irregardless of the exit status.

ok thanks… Will having a mutator which changes the exit status of the event output work here in this case?

A mutator will only be called if an event has been created that is being passed to a handler that requires it. Using a mutator will not work in this case, need to mark the check type as “metric”, or we implement an alias that doesn’t imply that it produces structure data.
