--------------------------------------
> Piggyback basic "alarm" framework on RS heartbeats
> --------------------------------------------------
>
> Key: HBASE-2629
> URL: https://issues.apache.org/jira/browse/HBASE-2629
> Project: HBase
> Issue Type: New Feature
> Components: master, regionserver
> Reporter: Todd Lipcon
> Priority: Major
>
> There are a number of system conditions that can cause HBase to perform badly
> or have stability issues. For example, significant swapping activity or
> overloaded ZK will result in all kinds of problems.
> It would be nice to put a very lightweight "alarm" framework in place, so
> that when the RS notices something is amiss, it can raise an alarm flag for
> some period of time. These could be exposed by JMX to external monitoring
> tools, and also displayed on the master web UI.
> Some example alarms:
> - "ZK read took >1000ms"
> - "Long garbage collection pause detected"
> - "Writes blocked on region for longer than 5 seconds"
> etc etc
