I'd probably use some of the more esoteric of the $JAVA_OPTS availalbe
at Sun's site to get more detailed logging, and then parse the logfile
for the info you need.
For instance:
you can use the jmap feature and get a heap histogram:
jmap -histo <PID>
or you can get heap metrics:
jmap -heap <PID>
Also check out the fields you can get from the Heap Profiler:
java -agentlib:hprof
Most of that output can be regexed out.
Any of that can be run via system() and then just parse through for
what you're looking for. There are other utilities out there, I'm
sure, but this is how I would do it.
(I do Apache+Tomcat+Java for The Weather Channel)
