Re: Monitor Results - Thread Count

[Andy Dawson]

 Hi List,

As the question remains unanswered (Why is the thread count always 0), 
and assuming I am not misunderstanding something fundamental, is it 
correct to conclude that:

   * The monitor looks at the first connector in the XML monitor
     results page
   * It's not possible to change/parameterize the connector monitored
     to generate thread busy %

I had at the source, calculateStatus seems to take the first connector, 
if that´s what get(0) means, but as I don't program in Java I don´t know 
what to conclude if anything from looking at the code ;).

Any help?

Thanks & Regards,

Andy Dawson

Hi Peter,

Thanks again for the reply.

The application, and therefore the thread count that is relavent, is 
on port 8100.

In the previous example, there were 8 busy threads at the time  (5% 
busy/max) which is shown in the xml. Even with > 50% of the threads 
active, it still shows 0%. How is the thread count determined?

I do hope there is something parameterizable to allow the busy thread 
% to be correctly determined.

Thanks & Regards,

Andy Dawson

looking at the response from tomcat, I see the following

<connect or name='http-8084'><threadInfo  maxThreads="150"
minSpareThreads="25" maxSpareThreads="75" currentThreadCount="25"
currentThreadsBusy="1" />

current busy thread is 1, the current thread count is 25 and max is the
default 150

so that means busy/max is less than 1%, which gets rounded to 0%.

what I generally do is hit tomcat with 20-50 threads and monitor the
performance using the monitor results.

hope that helps

Hi Peter,

Below is what tomcat is returning, the application, is running on port
8100. In this example the server was running with approx 75% memory
usage and 40% load. Although the number of theads is low compared to 
the
max defined (not my configuration) it isn't 0 percent and makes no
difference if I ramp up to 100 threads.

Anything that can be changed to see the thread count?

Andy Dawson
