Why ambari metrics grafana not include datanode java heapsize usage

[#1]

I use ambari 2.5.1.0. 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.

jvm.JvmMetrics.GcCount

jvm.JvmMetrics.GcCountConcurrentMarkSweep

jvm.JvmMetrics.GcCountParNew

jvm.JvmMetrics.GcNumInfoThresholdExceeded

jvm.JvmMetrics.GcNumWarnThresholdExceeded

jvm.JvmMetrics.GcTimeMillis

jvm.JvmMetrics.GcTimeMillisConcurrentMarkSweep

jvm.JvmMetrics.GcTimeMillisParNew

jvm.JvmMetrics.GcTotalExtraSleepTime

jvm.JvmMetrics.LogError

jvm.JvmMetrics.LogFatal

jvm.JvmMetrics.LogInfo

jvm.JvmMetrics.LogWarn

jvm.JvmMetrics.MemHeapCommittedM

jvm.JvmMetrics.MemHeapMaxM

jvm.JvmMetrics.MemHeapUsedM

jvm.JvmMetrics.MemMaxM

jvm.JvmMetrics.MemNonHeapCommittedM

jvm.JvmMetrics.MemNonHeapMaxM

jvm.JvmMetrics.MemNonHeapUsedM

jvm.JvmMetrics.ThreadsBlocked

jvm.JvmMetrics.ThreadsNew

jvm.JvmMetrics.ThreadsRunnable

jvm.JvmMetrics.ThreadsTerminated

jvm.JvmMetrics.ThreadsTimedWaiting

jvm.JvmMetrics.ThreadsWaiting

@Aravindan Vijayan

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
