Hello,

What's the best way to:
1. Get the percent cpu usage (as in top)
2. Get disk activity (eg. number of bytes read/written from/to disk 
during some period of time).

Ad1) I know I could find the cpu usage in top sources, but unfortunately 
I don't have enough time
to do it currently - maybe some of you did this already.
There is sysinfo() system call that returns average loads during the 
last 1, 5, and 15
minutes but average load, AFAIK, is a average number of tasks waiting 
for cpu, so it's not
exactly what I want.

Cheers
AD
