Hi Ambarish, you could add following property in your applications properties.xml file.
<property> <name>dt.application.*.attr.containerJvmOpts</name> <value>-Xloggc:<LOG_DIR>/gc.log -verbose:gc -XX:+PrintGCDateStamps</value> </property> when this property is used, you will see gc.log file in container directory. - Tushar.
