2299.0. "T1.2.4 statistics problem" by HAZARD::BAKER (Paul Baker, UK Product and Technology Group - 844 3311) Fri Feb 07 1992 16:32

I tried saving statistics to a file that were gathered once a minute with a 
duration of one minute (default), with the results as shown below. Basically, 
trying to save stats every minute with everything else defaulted results in 
some samples being missed. Note especially the times of each result.

Has anyone any suggestions, or is this a limitation (bug)?

Paul

2299.1Increase the repeat factor.TOOK::ANWARUDDINAnwarFri Feb 07 1992 17:598
If you are using the default duration of 1 min. & repeating the operation 
every minute you will miss some intermediate samples because of

	1. network traffic
	2. processing overhead

You can reduce the number of samples missed by repeating at every, say, 65 
or 70 secs instead of 60 secs. We are trying to reduce the overhead.
