Re: Tomcat monitoring
I have found Lamda Probe to be quite useful and easy to use for monitoring the Tomcat container. http://www.lambdaprobe.org/ Simply deploy the probe war file to the container you want to monitor! You can detect requests that have large processing times by monitoring the connector status tab. This sometime comes in handy and is easier to use/read than a raw log file. http://www.lambdaprobe.org/d/screenshots/full/status.png Having said that, as Chris mentioned in his reply, you can also enable the required logging and have the information logged to relevant log files.

Re: Tomcat monitoring
Dear Tokajac, As far as I see http://www.zabbix.com http://www.zabbix.com is not available for WinXP (that's my platform). *shrug* You could always run it on FreeBSD or Linux in VMWare. I downloaded Zapcat. Can Zapcat be useful without zabbix? No, it only works as a bridge to Zabbix. That's what it was designed to do. Here is a discussion about some other tools that you can use to monitor your VM. http://java-monitor.com/forum/showthread.php?t=1 There is also Zenoss and MC4J.

Re: Tomcat monitoring
Dear Tokajac, I want to monitor performance of Tomcat server when I'm running an application. Memory usage, threads, objects, user sessions, sql queries and as much as possible of other information on server. JMX is the way to go. JConsole was already suggested. If you want to really monitor the performance of an application you also need information from the actual host (disk I/O load, network load, processor load, RAM fill level. You should consider that tools such as JConsole only show data that is gathered as long as JConsole is running. External monitoring tools also allow you to gather information continuously, across reboots and new software versions. That gives you the ability to 1) do long term resource requirements prediction and 2) see what version of your application introduced or solved the memory leak. :) There are loads of tools out there that can do this. Personally, I use http://www.zabbix.com , combined with the Zapcat JMX to Zabbix bridge (http://www.kjkoster.org/zapcat/Tomcat_How_To.html ). -- Kees Jan http://java-monitor.com/forum/ [EMAIL PROTECTED] 06-51838192 Human beings make life so interesting.

What is recommended for monitoring Tomcat? Or is there anything built in

More specifically, I'm trying to find a way to time how long it take

returned.
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:
/**

* @param request - Request object
* @param response - response object
* @param chain - next filter in the chain.
*/
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain)

{
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();
}
}

maxProcessingTime);

logger.debug(uri + in + (t1-t0) + ms);

Re: Tomcat Monitoring
please define monitoring. which data do you want to get? do you want to monitor your production webapps status? monitor your hits? availability? leon On 7/12/06, Mr Alireza Fattahi [EMAIL PROTECTED] wrote: Hi, We are using Tomcat 5.5, please let us know if there are any monitoring tools that we can use with this server.

Re: Tomcat Monitoring
When starting a new thread (ie sending a message to the list about a new topic) please do not reply to an existing message and change the subject line. To many of the list archiving services and mail clients used by list subscribers this makes your new message appear as part of the old thread. This makes it harder for other users to find relevant information when searching the lists. This is known as thread hijacking and is behaviour that is frowned upon on this list. Frequent offenders will be removed from the list. It should also be noted that many list subscribers automatically ignore any messages that hijack another thread. The correct procedure is to create a new message with a new subject. This will start a new thread.
