>          Components: appmaster

>
> Use the codahale metrics lib to instrument slider AM with relevant metrics
> # cluster state, failure state, outstanding requests, ...
> # performance of operations (web &c)
> This could then be published:
> # register as JMX provider
> # maybe: publish as ganglia
> We should identify and focus on what tends to matter: are the containers up, how many are outstanding, what is the failure rate of the containers
> Also: liveness tests?
