Re: Performance Monitor PM400 on V5R4

Hi Pete

I asked about arms as an example - I don't know if this is important
parameter.

I'm looking for information where will be described what each parameter in
PM grabh exactly means,
and which values are good or not.

I started PM at november 2010.

5% to 10% arm utilization was in last 1,5 years.
When I'm looking at arm utilization (average) in last three days, the max
arm utilization is about
35% during night backup - it is full backup every night, and about 10% in
day work.

If all your arms are at 5 to 10% utilization then you are good. Now, you
didn't say for how long that collection period is for. If that is 24

hours,

well that is way too long because you are just averaging averages. You

need

to do some 15 minute snap shots during your busy time.
