Perf-O-meter for Windows Services

HI all!

I am searching for a simple example for writing a new Perf-O-Meter based on Ram. I have some Windows Services, as example the Apache Tomcat which are monitored by checkmk. The only problem is there is no Perf-O-Meter ootb. I know this is a simple task, bu i am standing at the beginning. Does someone have a code example which may work ?

Hope to hear from you soon,
cheers Christian

For which version do you need an example?
