I use ambari 188.8.131.52. and hdp 2.4
I open grafana data and not found datanode jvm metrics on the dashboard,
Why there has no these metrics? and is there a way to auto add them?
I believe those were missed out since they are less used than the current DN metrics in the Grafana dashboard. However, you can create a new Datanode JVM dashboard on Grafana though. The following jvm metrics are available and collected.
I just found some simple java metric on grafana,only GC TIME / GC TIME PARNEW
But I want to know detail of java metrics such datanode heapsize usage,yong gc count and time which ambari metrics collected
Grafana shows me "This dashboard is managed by Ambari. You may lose any changes made to this dashboard. If you want to customize, make your own copy."
So I don't know how to let them show on grafana automatic
