is jmx enabled on tranquility server which uses jetty? if not, how would i enable it?
http://druid.io/docs/latest/configuration/production-cluster.html has basic JMX settings examples, and https://docs.oracle.com/javase/8/docs/technotes/guides/management/agent.html has some more configuration information.
Are there particular things special to jetty you are hoping to see through JMX?
requestTimeMean requestTimeStdDev requestsActive requestsActiveMax responses2xx responses4xx responses5xx from the org.eclipse.jetty.server.handler:type=statisticshandler mbean on jetty.
Most use cases I know of use http://druid.io/docs/latest/operations/metrics.html for metrics collection and monitoring.
Looks like this specific bean is missing at https://github.com/apache/incubator-druid/blob/druid-0.12.3/server/src/main/java/io/druid/server/initialization/jetty/JettyServerModule.java#L211-L216
Such a feature is a very reasonable ask. Would you mind filing an issue at https://github.com/apache/incubator-druid/issues highlighting your use case and calling out the ways the current metrics system does not solve what you need?
my request is specific to druid tranquility server though. But, i can create an issue for druid too. it is definitely helpful.
Oh shoot, sorry I missed the tranquility part. Unfortunately I’m not as familiar with tranquility :-/
