Small oddity - specifying max number of processes but no minimum.
I have a process named "foo". It is ok if there are zero instances of this process running, or one or more. I want to alert when there are more than three instances.
If I put in analysis.cfg:
PROC foo -1 3 yellow
and there are no foo processes, the procs page shows: green foo (found 0, req. 1 or more)
Color is correct, message is inaccurate Then if I have more than three I see:
yellow foo (found 11, req. 1 or more)
So I think the test is correct but the message is confusing.
also it's not explicitly documented that you can use -1 to mean "no minimum"
(server and client are 4.3.7)
I think -1 only works as the max value. For the minimum, zero is the more natural number to use.
Thanks, Larry Barber

Doesn't "0" mean that it should NOT be running, or is that only if the minimum AND maximum are zero?

The latter, or if min=0 and max=-1.
The min and max define the permitted range, and are inclusive (a value of exactly the min or the max is permitted).
min max -> meaning, "display text" 0 -1 -> must have exactly 0 running, "found X, req. none" 1 -1 -> must have 1 or more running, "found X, req. 1 or more" 0 0 -> must have exactly 0 running (ie, not running), "found X, req. at most 0" 0 1 -> must have zero or one instances, "found X, req. at most 1" 1 1 -> must have exactly 1 running, "found X, req. between 1 and 1" 0 3 -> must have no more than 3 running, but can have as few as zero, "found X, req. at most 3"
As Larry said, -1 is only special when it is a maximum.
