Re: Measuring IOPS

monitoring such OS near metrics, I'd suggest to do the collection on OS. Database metrics are valuable, but for absolute numbers I'd suggest to use tools like iostat ot iotop for real time monitoring, and stuff like nmon (Nigels Monitor) for historical values.

They all have very low footprint and are very easy to handle.
