Java app performance counters viewed in Perfmon

jmxmbeansperfmon

I have a Java app running on Tomcat, and I would like to monitor counters using Windows Performance Monitor. Is this possible using a JMX adapter for the Java MBeans or by some other means?

Since you tagged this with JMX and MBeans, I assume your counters are accessible from a Java MBean. If so you could use jconsole, provided with the Java SDK, to monitor the counters. Once you find your MBean in the MBeans tab, double click on the value and it will draw a nice line graph for easy monitoring.

See JConsole Guide for more info.

Does your program happen to be a 32-bit program running on Windows 2008 R2 or another 64 bit windows OS? If so you may want to check that the service "Performance Counter DLL Host" is running. This service enables 64-bit and remote processes to query counters provided by 32-bit processes.

Tomcat – Accessing built-in MBeans in Tomcat programmatically

I think there's a typo in your second snippet of code. You created a new ObjectName for the Catalina ThreadPool called mbeanName2, but when you try to retrieve the attribute "name", you're still using mbeanName.

So it should be:

ObjectName mbeanName2 = new ObjectName("Catalina:type=ThreadPool,name=\"http-apr-8080\"");
Object value = mbsc.getAttribute(mbeanName2, "name");

Other than that, you code should work fine.
