java cpu usage monitoring

I'm trying to write a program in Java that can shutdown your computer when the computer hasn't been active (like CPU usage) for an amount of time.

I have written a program that can shutdown your pc (windows/mac/linux) after an amount of time. But i don't seem to find a way to check for the CPU usage or inactivity in JAVA.

Can anyone help me pls?

kind regards,

I'm afraid you probably will have to find a native library. There doesn't appear to be any non-native way of acquiring the CPU usage, however there is support for finding memory usage and other usage indicators.

If you wanted to implement this yourself in a native way, you could look up what terminal command shows you your CPU usage, such as for linux you could execute the top command and then parse through Java.
