Performance

I'm looking for a tool or a script that will take the console log from my web app, parse out the garbage collection information and display it in a meaningful way.

I'm starting up on a Sun Java 1.4.2 JVM with the following flags:

-verbose:gc -XX:+PrintGCTimeStamps -XX:+PrintGCDetails

The log output looks like this:

54.736: [Full GC 54.737: [Tenured: 172798K->18092K(174784K), 2.3792658 secs] 257598K->18092K(259584K), [Perm : 20476K->20476K(20480K)], 2.4715398 secs]

Making sense of a few hundred of these kinds of log entries would be much easier if I had a tool that would visually graph garbage collection trends.
