Monitor Memory usage and Garbage Collection in Bamboo

A simple way to do this is to turn on garbage collection and heap dump on out of memory.

Please add the following parameters to the run command line in bamboo.sh

...
RUN_CMD="java -XX:+PrintGCTimeStamps -verbose:gc -Xloggc:gc.log -XX:+HeapDumpOnOutOfMemoryError -Xms256m -Xmx<your-setting> -XX:MaxPermSize=256m ........
...

Then restart bamboo as ./bamboo.sh start.

Windows

Add the following parameters to wrapper.conf as startup parameters
-XX:+PrintGCTimeStamps
-verbose:gc
-Xloggc:gc.log
-XX:+HeapDumpOnOutOfMemoryError

The garbage collection traces and the heap dumps are in <bamboo-install>/gc.log.
