getting cpu_idle and iowait percent

[Simon Jespersen]

Hi! im not that familiar with tru64, i want to be able to get the total cpu_idle. and the iowait on the box out to use in a script.
normally i would use the sar and collect the data with awk.
I think that i could use the collect tool to do this on tru64 but i dont know how, im a bit confused after reading the man pages ect..

So how do i get those overall performance data out.
with a cmd or more commands.
I need them in a performance trend analyse database.

You can use vmstat -w 1 2 to obtain these values. The first line is not relevant because is statistics since the startup of the system, the second line displayed will be the current usage.

Simon,

There is uitlity (Host Sensor)using which we can get complete CPU usage, iowait and other resouce utilizations in the system...

You can find Host sensing modules for Tu64 too here.
