Overview
GC logging is enabled by default for standalone mode (to verify form which version on). It generates output to $JBOSS_HOME/standalone/log/gc.log.<digit>. The system uses log rotation with the number of log files limited to 5, and the size of each file limited to 3 MB.

Enabling GC Logging in Domain Mode
Server Node
The GC logging can be enabled for a specific server node, or generically, across the server group.
To enable GC logging for just one server node,
To enable GC logging for an entire server group, edit the <ivm-options> section corresponding to the <jvm> configuration specified for the server group, in domain.xml.
In both cases, add the following JVM options:
<jvm-options> </jvm-options>
