Suddenly sensu-api service died

Hi

Unexpectedly sensu-api service (running on an ubuntu) has died. It is all I found in the log:

{“timestamp”:“2015-03-09T14:53:03.726878+0000”,“level”:“fatal”,“message”:“transport connection error”,“error”:“rabbitmq channel closed”}

{“timestamp”:“2015-03-09T14:53:03.726945+0000”,“level”:“warn”,“message”:“stopping”}

{“timestamp”:“2015-03-09T14:53:04.227920+0000”,“level”:“warn”,“message”:“stopping reactor”}

It happened a couple of time already.

My questions are:

  1. Do we know why it may happen? Is there any way to prevent it?

  2. Can we monitor the health of sensu-api? If so, how it can be done? I have only one instance of sensu server

Cheers, Tony
