Trigger a handler on status 0

Brice_Argenson · March 20, 2015, 1:26am

Hi everyone,

I wrote a sensu plugin generating some reports based on Graphite and Logstash metrics and I would like to send them by e-mail at each execution of my plugin.

I already have a mailer handler defined so I was thinking to use it.

The documentation says the following:

By default, only non-zero (exit status > 0) check results produce an event, causing the creation of event data which is passed to one or more handlers.

The By default let think we can customize that somehow…

So my question is the following: can I configure a check to always trigger a handler, even with a status to 0? How?

Thanks for you help

An email on *every* event? Sounds like a lot of emails?

You can configure a check to always fire on a handler by setting it to
be a "metric" check:
http://sensuapp.org/docs/latest/adding_a_metric

I believe this is the code where that (metric checks are always
processed) is encoded:

sensu/sensu/blob/2b181417cf584bedc8a1921b8096cea6ea408c30/lib/sensu/server/process.rb#L313-L331


      
          if check[:status] != 0 || flapping
            if stored_event && check[:status] == stored_event[:check][:status]
              event[:occurrences] = stored_event[:occurrences] + 1
            end
            event[:action] = flapping ? :flapping : :create
            @redis.hset("events:#{client[:name]}", check[:name], MultiJson.dump(event)) do
              callback.call(event)
            end
          elsif stored_event
            event[:occurrences] = stored_event[:occurrences]
            event[:action] = :resolve
            unless check[:auto_resolve] == false && !check[:force_resolve]
              @redis.hdel("events:#{client[:name]}", check[:name]) do
                callback.call(event)
              end
            end
          elsif check[:type] == "metric"
            callback.call(event)
          end
