Support for "aggregate checks" #1041
I'm not sure the title really conveys what I'm trying to say here, let me explain.
One of the thing I want to monitor is a Mesos cluster, which runs Docker. One of my checks would be "I need to have at least three instances of this Docker container across my whole cluster".
The same paradigm could be applied to some other datacenter-oriented OS's, with a check that would be triggered if the total available RAM across the cluster falls beneath a certain point.
At this moment, to my knowledge, checks only apply to a single node's context.
Thank you for your ideas and suggestions.
Hello @apognu, this functionality currently available Sensu core, and is known as check aggregates
Just to be clear, there is or is not support for standalone aggregates yet? I see a few different open issues/PRs about this. Unless I'm missing something, my only option for standalone aggregates at this point is to make a check querying/aggregating redis data directly like @solarkennedy has done with his cluster check script. @portertech , is this true?
