Sid,
I know of sar but how do I run it?
just by 'sar' command or any other parameters?
I can't afford overhead as this is production;
as to vmstat: just by command or anything else?
Thanks,
Ibrahim

You can use sar or vmstat
They give you system level health.
If you need inside the jvm health you can run the jvm in hprof mode. It
adds
plenty of overhead so beware.

Only one I know of is "top" which gives me cpu/memory/disk usage;
wondering if there was freeware on the web or other commands anyone knew
of?

you might try looking within the server it's (Tomcat) residing on -- be it
Unix or IIS. Either might have some non-sophisticated, built-in tools to
help gauge it.

Hello.
I'm creating a new thread regarding tomcat performance monitoring.
I am using Tomcat 4.0.6 in a Vignette content management application.
I need to monitor Tomcats performance real time.
Could someone suggest any answers?
Up till now, the only sure way was to do a kill -3 JVM-PID and get a
thread dump,
which gives ample information but it is post-incident.
Are there any tools I can download and use or any commands someone can
suggest?
Thanks,
Ibrahim
