Monitor Memory usage and Garbage Collection in Bamboo

These are some recommended settings to enable Garbage Collection logging and Heap Dump when Bamboo runs on Out Of Memory.


Please add the following parameters to Bamboo. Make sure to select the correct Java version.

Java 8:

-Xloggc:<bamboo-home>/logs/atlassian-bamboo-gc-%t.log -XX:-OmitStackTraceInFastThrow -XX:+PrintConcurrentLocks -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=<bamboo-home>/logs/atlassian-bamboo-heapdump-%t.hprof -XX:+PrintTenuringDistribution -XX:+PrintGCDetails -XX:+PrintGCDateStamps -XX:+PrintGCTimeStamps -XX:+PrintGCApplicationStoppedTime -XX:+UseGCLogFileRotation -XX:NumberOfGCLogFiles=10 -XX:GCLogFileSize=10M -verbose:gc

Java 11:

-Xlog:gc*,gc+age=trace:file=<bamboo-home>/logs/atlassian-bamboo-gc-%t.log:time,level,tags:filesize=10M,filecount=5 -XX:-OmitStackTraceInFastThrow -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=<bamboo-home>/logs/atlassian-bamboo-heapdump-%t.hprof

Note: Remember to substitute <bamboo-home> with a correct Bamboo Home path on your server.

GC log file location

The garbage collection traces and the heap dumps are in <bamboo-install>/logs/atlassian-bamboo-gc-%t.log. Where %t, is the time the file was created.

Additional Note

The -XX:+PrintGCTimeStamps flag, prints when GCs happen relative to the start of the application. That's applicable to Java 8. On Java 11, the timestamps are implicit by -Xlog:gc*
