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: /manager for the webs
You will also need a context entry for the manager app. I just did it by putting a copy of manager.xml in the TOMCAT_HOME/conf/Catalina/NEW_HOST_NAME. I could get see the manager app from both hosts but they both had the app listing from localhost. So, you need to fiddle with it a bit. I'm not a guru with this stuff. I've never needed a second host. If you search the archives, I'm sure you'll find plenty of examples. I've seen this issue discussed on several occasions. Another option, of course, is to give each client a separate instance of Tomcat. Then each client will be running in their own JVM which makes it a lot easier to protect one client from the stupidity of another ;) You can instanciate them all from the same code base by setting up different CATALINA_HOME and CATALINA_BASE environment variables.

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?

Re: JSP compilation problem
Quite simply, you have an error in your JSP that is preventing the translated servlet from compiling. If you don't know where to look for the compiler output, then just go and manually compile the servlet. -Original Message- From: Frank W.

Re: java.lang.NullPointerException in tomcat 5.5.4
In your login.jsp you're calling the dispatch method of gnu.beanfactory.servlet.Dispatcher and most likely passing it null as an argument.

how to tell if Jikes is being run??
I gleaned info from this mailing list archive and other websites and configured my Tomcat to use the Jikes compiler instead of the one from the Sun JDK. Nothing seems faster, so I must've done something wrong. Question is - is this the only way to tell if I'm actually using Jikes - to see if I'm running/compiling faster?? Thanks. --Peter--

Yes... 1. remove the work directory 2. Start to compile a page 3. pgrep -f jikes If it shows up then its working. If that doesn't work you'll have to do a killall -3 java and look at the stack trace to make sure the right compiler is being used. In my experience jikes doesn't speed up page compilation much.

Re: JSP compilation problem
Interesting response... The exact same JSP is compiling on two other machines. Your right though, manually compiling it is a good next step (one that I'm ashamed to say I didn't think of myself), so I'm off to do that now. Maybe I have a corrupt file in some minor, hard-to-detect way that is causing a problem on this one Tomcat instance. Thanks for the suggestion, it's a logical course of action. -- Frank W.

Re: how to tell if Jikes is being run??
When you use Jikes or any other out-of-process compiler, you're spawning a full heavy-weight system process for each compilation. That overhead seems to offset at least some of the performance advantage of using jikes. You should be able to see the jikes instance running in whatever you use to see running processes, depending on how long its running. I don't know the specifics, but I believe Tomcat 5.5.x uses a faster, in-process compiler (by eclipse, I think).
