Seems there is now. Haven't tried it yet, but will soon, if I can
upgrade that Tomcat. Previous messages in this thread give more clues.

The disadvantage of running these tools on the server that also runs
Tomcat is that these tools generate certain load, which under some
circumstances is not wanted as it might influence the stats.

Hi.
Thanks Chris and Peter and Gregor.
Gregor sent me a link to an article that looks promising, and says
basically the same as Peter below, using XMing as the X11 server
(client?, I can never remember..).
I will try that tonight.

Thanks Gregor, I wasn't aware of that one. Think I may just have a new

You can't, because it is variable. It is the result of some internal

You can use jmap from the command-line. That will give you a thread dump

Dear Steve,
One additional restriction I have is a security bureaucracy from
hell. As far as console access I have a two-hop connection.
Is there no test system that you can use to reproduce this, under less
insane restrictions? Have you considered hauling your behind to the

Hi Steve,
Some great tools to monitor your Tomcat installations are:
- Jconsole (make sure you get the topthreads plugin)
- VisualVM
- VisualGC
- Jmap
Hope that helps.
