@Raj77 You have to go CM > Cloudera Management Services > Configuration > Then Form category filter select Service Monitor
Then you can just search for Heap size and you will get SMON heap size there.

@Raj77 Your Service Monitor is running out of Java Heap hence the issue:
JvmPauseMonitor Detected pause in JVM or host machine (e.g. a stop the world GC, or JVM not scheduled): paused approximately 18430ms: no GCs detected.
So please increase the Java heap size for SMON to resolve the issue. Refer the Requirements here for Heap size: https://docs.cloudera.com/cloudera-manager/7.2.1/managing-clusters/topics/cm-configuring-memory-allo...

My cluster Java Heap memory values kindly please check this values.
Raj@77 Your Service Monitor is running out of Java Heap hence the issue:
where can i found exact location of service monitor using java heap memory value. is there any specific requirement for service monitor Java Heap value.
Is there any issue.
