 Take a look at the jstack tool to remotely access stack traces on a
 running JVM:

 t

 If accessing remotely, you'll also need jsadebugd; if running jstack
 locally, you don't need the daemon.

 You can also use JConsole, but it only dumps the stack for one thread at
 a time.

Re: find out the possible bottleneck webapp

Hi,

Thank you all for the reply!

I am sure that's some of my webapps' problem.
It runs ok at beginning. After it runs one day, the CPU usage is very high,
I have to restart Tomcat.

Of course, I can use JProber to analzye which webapp goes wrong.
But I don't want restart Tomcat. I want to find that abnormal webapp and
delete it
directly.

So what I want is a light weight tool, just find out which webapp causes the
problem when Tomcat runs abnormally.

Is there this kind tool?

find out the possible bottleneck webapp

[maggie]

Hi ,all

I deploy many web applications on Tomcat.
But sometimes the response time of Tomcat is very long. At that time,
the CPU usage is very high.

Is there any tool for me to find out which web application consumes most
of the CPU resource?

Is there any tool to provide such information Remotely even if the
workload of Tomcat is very heavy?

Any hint is welcome. Thanks in advance.
