Monitoring standalone java program

[indu pai]

Hi,

I have a jar file that contains many java files. It has a main class, and many service classes. The main class is invoked at scheduled intervals, through shell scripts.
There are multiple applications calling this main class in my jar file. There is a chance that at the same time more than one application invokes the
jar file. I would like to monitor the thread and memory utilization for this jar file. IS it possible? Which tool is best to use in this scenario?

Regards,
Indu

Please try JConsole. There are tabs for memory usage and threads. See http://java.sun.com/developer/technicalArticles/J2SE/jconsole.html

Or you can also use visualvm if you use jdk 1.6 update 7 for solaris and update 4 for mac. It does what jconsole and adds a few new features. I have recently been using it to monitor tomcat however it works on any jvm.
