Tomcat Monitoring
What is recommended for monitoring Tomcat? Or is there anything built in
that can help monitoring the performance and the state of the thread
pools?
More specifically, I'm trying to find a way to time how long it take
from the moment a request was received and when the response was
returned.
Thanks,
Ross

I have a suite of filters, one of which does exactly this. Mixed in is a
display servlet which dumps out all requests, by URL including request
count, min, max and average request times. PM me and I'll send it your way.
The main method looks like this, if you want to write your own:
/**
* Process the container's filter request.
* @param request - Request object
* @param response - response object
* @param chain - next filter in the chain.
*/
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain)
throws IOException, ServletException
{
hitCount++;
HttpServletRequest httpRequest = (HttpServletRequest)request;
final String context = httpRequest.getContextPath();
String uri = httpRequest.getRequestURI();
uri = uri.substring(context.length());
URICount count = new URICount(uri, 1);
synchronized (pages) {
final int index = pages.indexOf(count);
if (index < 0) {
pages.add(count);
}
else {
count = (URICount)pages.get(index);
count.increment();
}
}
lastRequest = new Date();
long t0 = System.currentTimeMillis();
chain.doFilter(request, response);
long t1 = System.currentTimeMillis();
final long requestTime = t1-t0;
count.addTotalTime(requestTime);
processingTime += requestTime;
maxProcessingTime =
(requestTime > maxProcessingTime ? requestTime :
maxProcessingTime);
if (logger.isDebugEnabled()) {
logger.debug(uri + " in " + (t1-t0) + " ms");
}
}

For general purpose use jconsole.exe from SUN's JDK.

Hmm, maybe it's better to use performance analyzer like the
"Test and Performance Tools Platform" (a.k.a. TPTP) from Eclipse.
