The I/O-activity simply reports the number of I/O actions (in practice reads and writes) that during the last 30 seconds were performed on behalf of that session. A session with a high number causes more load than one with a low number, but it cannot easily be translated into, say, CPU percentage. The general problem is that the cost of collecting load-information must not be expensive, as it is continuously on-going, but must be cheap without causing any overhead.

Let's return to the beginning. What is the actual goal; what do you need the per-session activity/load number for?

Can we please highlight at least in terms of color (Red, Yellow and Green) and show top loaded session in the top right. will it be possible to show on the dashboard?

and can you please add some popup window like memory info? How its showing memory like expecting some info what is I/o load and all.

Could you please turn those last two suggestions into a separate feature wish.

Johan,

Can you please convert this ticket to feature request, I am okay with it.
