Monitoring system resource use for Java

Question

Hello,

I am trying to prepare some statistics on the CPU and Memory usage (over time) of a Java application running on a Windows XP machine.

Is there a (free) tool that would let me obtain these statistics? Most of the tools I looked at either profile the existing code for CPU and Heap usage - but do not provide a view the process itself (from a systems point of view).

I tried using IBM Performance Analysis Tool for Java but this does not seem to provide a straightforward metric of determining the amount of memory the process is consuming (similar to the ProcessExplorer tool).

Any pointers would be much appreciated.

Kind regards, Dinuk

Answer 1

You could always try the perfmon tool which is bundled with windows.

Answer 2

Try the profiler included in the Netbeans IDE package. For more information about the details of their profiler see their profiler page.

Answer 3

Sigar might provide what you want

Answer 4

The best option is JNI wrappers if your operating system is windows XP 32 or 64 bit.

JNI wrapper and evaluation key are available here for one month/trail. This is very easy to configure (documents available) and this can give all information (working set, page file, memory details, cpu information ..etc) about specific process.

Perfmon is good on Vista operating system.

Answer 5

I would highly recommend looking into a tool like Hyperic or zenos. These tools can monitor a Java app in multiple ways; an agent installed on the system, via JMX MBeans, or by SNMP.

Answer 6

Do you actually want to "monitor" or "profile"? For the monitoring side of life, there is also Jopr (http://www.jboss.org/jopr/).

In general you should take into account that the shorter the measurement interval is, the more load you put on the targeted resource.
