I'm planning to implement a framework for monitoring OS level resources:

• process
• network stats
• cpu info etc

using JAVA.

I see there is SIGAR API by Spring, which is implemented in native language and JAVA API being provided on top.

But I will prefer not to have native stuff in my framework, rather for each OS will write a Java Class which will fetch required OS info by running system commands via JAVA Runtime.

So I would like to have inputs/suggestions that one may have seen of not doing this in JAVA and use native app/api/jni. Any example will help for sure. I agree each OS has different commands to get these stats, but will prefer to have a Java Class per OS than have/load native code.
