Disk Utiliztion ( not space )

Josh Owings — Wed, 28 Aug 2002 15:09:24 GMT

Everyone,
I was wondering how I could get the percentage of disk utilization by disk.
In HPUX you can do 'sar -d' and you get the followings fields:
'device,%busy,avque,r+w/s,blks/s ,avwait,avserv'

The '%busy' is the field I am interested in. In my Linux box i only get 'DEV,tps,blks/s' with 'sar -d' and 'tps,rtps,wtps,bread/s,bwrtn/s' with 'sar -b'.

I appreciate any help.

AFAIK, the Linux sar does not have %busy for disk devices. Neither does iostat but you can use iostat to get stuff like the queue lengths for I/O and the times to service those requests which are more meaningful measurements than "percent busy".

HTH,
Paul

Unfortunately, they want to see the % so that is what I am inclined to provide.
