How to setup the monitoring to capture the IO bandwidth?

[praveen..]

I have 8 CPUs in my server. When I was watching TOP for a while, it would fluctuate; sometimes all CPU’s were active at 60+% used then it would go down to 1 or 2 cpu’s then back up to all 8 over a period of a couple of minutes.

What IO was happening.

Can I setup the monitoring to capture the IO bandwidth?

I want to get in on my email.

Please suggest
