Garbage collection notification?

Question

I\'d like to register a callback with the JVM so I know when garbage collection is happening. Is there any way to do this?

EDIT: I want to do this so I can log out

Answer 1

Regarding -Xloggc: As of jdk1.6 update 4 you can get the Sun/Oracle JVM to print out the date and time using -XX:+PrintGCDateStamps. This makes the logs much more useful, especially if you add a log scanner / monitor that can notify you of any GC issues.
