@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-allocations.html

 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.

 /etc/default/cloudera-scm-server


 Java Options.
#
# Default value sets Java maximum heap size to 2GB, and Java maximum permanent
# generation size to 256MB.
#

export CMF_JAVA_OPTS="-Xmx2G -XX:MaxPermSize=256m -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/tmp"

 

 

 Heap size: https://docs.cloudera.com/cloudera-manager/7.2.1/managing-clusters/topics/cm-configuring-memory-allo...    Link is not working
