Peter, W e have a content management application using Vignette software for development. We use Tomcat 4.0.6 as our 'appserver', IHS for webserver. And oracle as our database. We're running on solaris machines. Last week we applied a efix supplied by the vendor (Vignette) for a problem that has existed since feburary. The site had been crashing nearly every week and each time the only resolution was to restart Tomcat.
The efix is to remedy this by replacing a particular .jar file which the app uses. What I would like is to visually see the performance of Tomcat in real time. To see how it's performing in dealing with jsp pages and requests. What the heapsize is, how much GC is being used etc. The thread dump was a post-incident way of analyzing tomcat as it provided the key in finding a solution. We had seen methods/classes being called just prior to the java deadlock and were able to conclude which efix was needed. Still however we could suffer other deadlocks and more crashes so as a preventive method I'd like to analyze the overall performance of tomcat in real time.

What aspects do you need to monitor? If you say that a thread dump gives ample information but post-incident, I assume this is *not* monitoring resource usage? Please give us more information on what you're trying to accomplish, and we'll probably do better at hitting the target! - Peter --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] ****************************************************************************** This communication (including any attachments) may contain privileged or confidential information intended for a specific individual and purpose, and is protected by law.
