Hey hi,
Back to you again :)
I felt the idea you gave was correct (delta of raw idle/ delta raw* ) as I
feel the second idea is wrong, as some cases this counter doesn't represent
timeticks.
But I had bit doubt I am using suse linux 8 and suse linux 9( having
ucd-snmp and netsnmp 5.1-80.3 respectively)
In these OS I am getting values for raw user,nice,system and idle but not
for wait,kernel and Inttrpt. In this case if I still apply the formula
"delta raw Idle / sum( delta( raw* ))" will it still hold good.
I also wanted to know what these raw counters signify (time ticks or what
else ??? ) and why is it different in diff versions.
Thanks a lot,
Naga

Correct.
(Though not all these objects will necessarily be valid on all systems)

Hmmm....
That's *probably* true - but it's not guaranteed.
(I'm not at all sure what would happen with multi-CPU
systems, for example)
The simpler formula you suggest will probably work
in most cases. Suck it and See.
The formula I gave is rather more complicated,
but it's guaranteed to be valid.
