Iostat

[satyajit Biswas]

The quetion I have is in HP-UX when we run the iostat it gives the i/o
analysis at disk level and these are the headings
device Device name
bps Kilobytes transferred per second
sps Number of seeks per second
msps Milliseconds per average seek
can we use the bps and sps as the read IO/s and write IO/s?

Not really, the seeks per seconds have nothing (or at least little) to do with the read/write.
One seek could trigger any number of reads/writes.

All that means anything is the bps and that is total reads/writes per second.

sar -d probably gives you better data though nothing like glance. Also, note that you may have many,many more logical i/o's than physical i/o's. sar -b will indicate those statistics.

I want to basically measure the read and write separately at a individual disk level. Sar -d gives fisk level analysis but it sums up the read and write activity and sar -b gives a genearlized level info not at a disk level.

Thanks

Hi:

Take a look at 'glance'. You can install a trial version from one of the Application CDROMs if you don't already license it.
