Re: monitoring performance
you can easily setup JMeter to monitor tomcat and save the results to a log. peter lin On 6/17/05, Hossein S.

RE: monitoring performance
Thanks for the reply. I set up JMeter using an example from the JMeter site (http://jakarta.apache.org/jmeter/usermanual/build-monitor-test-plan.html) . Apparently JMeter uses manager/status and shows only load, # of threads, and memory used. Is it possible to make it measure average response time (both total average response time and per-servlet average response time)?

Re: Monitoring Performance Tomcat 5.0.28
you could use jmeter's tomcat5 monitor. there's a coupl of commercial tools out there that can monitor your production servers. peter On Thu, 30 Dec 2004 23:27:05 -0800, Hari Mailvaganam [EMAIL PROTECTED] wrote: Hi: What would be the best way to monitor the performance of Tomcat - while in production? Apache HTTP server has an option that can view threads etc of a production web server. Does Tomcat have anything equivalent? On a separate note are there any kind of benchmarks on performance of Tomcat available online - i.e throughput, response times? It can be a challenge finding benchmarks that fits ones criterias - as there are a huge number of variables to consider. I was hoping to find one which had a study the base parameters.

Re: Monitoring Performance Tomcat 5.0.28
The jakarta JMeter monitor sends requests to Tomcat's status servlet and uses the stats there to generate a performance graph. You can monitor multiple servers with jmeter. If you use a third party tool, it will have lots of other features, but it most likely will not be able to utilize the stats the status servlet displays. the tomcat monitor I wrote specifically takes advantage of the status servlet to show performance. just go to jmeter's page and you'll see. peter On Fri, 31 Dec 2004 15:32:36 +0200, Jukka Uusisalo [EMAIL PROTECTED] wrote: Hari Mailvaganam wrote: Hi: What would be the best way to monitor the performance of Tomcat - while in production?
