Question about cpu usage of tomcat 4.1.30

Hi.

         I'm using tomcat 4.1.30 for my web applications.

         Here I got a requirement to get the CPU usage of tomcat process
both on windows and unix-liked systems(linux & AIX).

         So does tomcat give a API to get this information?

         

         I know it could be done by using JNI to call c program to get
this information, but it is tough for me to program c on linux & AIX,

So I wish tomcat has already done it.
