Hi Ambarish,

you could add following property in your applications properties.xml file.

<property>
<name>dt.application.*.attr.containerJvmOpts</name>
<value>-Xloggc:&lt;LOG_DIR&gt;/gc.log -verbose:gc
-XX:+PrintGCDateStamps</value>
  </property>

when this property is used, you will see gc.log file in container directory.

- Tushar.
