Its just representing activity over the most recent "period".

That period is probly relative to the last measurement displayed.

During normal operation, the LCD on an F7xx displays each second a number, which I believe to be the number of NFS operations in the last second, followed by a row of 0 to 10 splodges --- at any rate, I have never seen more than 10.

The hardware installation guide refers to this as "a bar graph" but doesn't go into details. What is actually being measured here? The number of splodges is correlated with the number, but not very strongly, and the number has a far larger dynamic range.

After staring at that thing and wondering myself, it looks to me as if it is sort of a sliding rate-of-change meter.

When there is a big surge in #/Ops over a short period of time, bar jumps up a lot. Ditto for a big decrease in ops, shaving the bar.

However, I've seen the bar nearly pegged with a relatively small number of ops (say, 400 or so) and hanging around 50% when the machine in question was pushing as many as I ever have seen it push.

In general, I think the main purpose is to have Cool Blinky Lights.
