[Orca-users] Question regarding Statistical Calculations...

[Sadat Chowdhury]

We have been using the orca system on a solaris machine and so far we 
have been able to get the system to gather data and generate html/graphs.

The statistics from the graphs, however, look a bit confusing. Here are 
some values quoted:

Daily:
Disk...Max: 3.56
1 min avg Process in Run Queue: Max: 5.753
5 min avg Process in Run Queue: Max: 4.990
15 min avg Process in Run Queue: Max: 4.150

Weekly:
Disk....Max: 2.13
1 min avg Process in Run Queue: Max: 3.901
5 min avg Process in Run Queue: Max: 3.966
15 min avg Process in Run Queue: Max: 3.966

The statistics generated for daily and weekly are from the same data 
set. They were both generated at the same time. How come the weekly max 
values are LOWER than the daily max values, when in fact, one would 
expect them to be at least the same or higher? For instance, if on 
Monday the max is 5.753 for any measure, for the entire week, it can't 
possibly be 3.901 - it has to be at least 5.753 or more (say of the max 
on Friday was 7.901).

Is there a reasonable explanation? anyone else experienced this?
