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.

Parameters

Please add the following parameters to Bamboo

-XX:+PrintGCDetails -XX:+PrintGCTimeStamps -verbose:gc -Xloggc:/path/to/gc.log

Note: Remember to substitute /path/to/gc.log with a meaningful file path on your server.

GC log file location

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

Additional Note

The -XX:+PrintGCTimeStamps flag, prints when GCs happen relative to the start of the application.
