    Monitoring kernel usage??



    I've been going insane trying to find out how to monitor the kernel usage in Linux.. I had a look in the system monitor but it didn't seem to show this information. Googled and also checked out the' top' and 'ps' commands and still no joy!

    Please help..
    Thanks

    ...

    tail -f /var/log/messages for kernel messages, and tail -f /var/log/syslog for system log...

    you can run this command on a transparent console fixed on the background...

    opss...

    no... I was wrong about your question...

    However using any system monitor (like top), System CPU usage is not enought for you?

    In Unix everything is a file :-)

    You can get almost any information imaginable from /proc on most nix'es.
    Sometimes you have to abstract the information but it is all their.
