OS Performance Counter

[unix fan]

Hi,

I would like to know "exactly the size of the data written by the OS in a single write request".
Which performance counter will help me to find out the current status in HP-UX 11.31?

Can anybody help me?

Regards,
Chandan.

check out vxtunefs /

if you are talking about file system writes

if you want raw I/Os then you have to get I/Os per disk that you can get from glance or measureware across time.
