Tao Yang commented on YARN-2599:
--------------------------------

Hi, [~Naganarasimha]. Some JVM metrics of standby RM can be evaluated whether 
standby RM is normal and can be transitioned to active. We have a requirement 
to monitor some metrics, can we revaluate whether standby RM should expose jmx ?

> Standby RM should also expose some jmx and metrics

> YARN-1898 redirects jmx and metrics to the Active. As discussed there, we 
> need to separate out metrics displayed so the Standby RM can also be 
> monitored.
