Bollocks. You'd be the first to complain that those stupid Cygwin devs
don't even understand what an average is.
Hold on there Tonto! I said nothing of the sort. If you're gonna put
words in my mouth then please refrain for claiming that I insulted
somebody else in the manner you did above. I didn't say that the Cygwin
devs didn't understand what a loadavg is and I hardly called them
stupid. You should be ashamed of yourself for making such a leap of
misjudgment and then pinning it on me!
The 0% tells you pretty
clearly that that information is not available.
I beg to differ. 0% is indistinguishable from "the machine was not busy
at all". IOW it *could* say "that information was not available" and it
*could* as easily say "the load avg was actually 0%". You can't tell so
it's hardly "pretty clearly". Indeed reporting say a negative number
would impart more information as the user would say "Huh?!?" and then
perhaps the man page could explain that a negative number is returned
because this information is not easily obtainable by Cygwin under
Window. But reporting 0 is by definition ambiguous!
I beg to differ. I don't see how having 0 values is better than some
approximation of load. Surely Windows has some measurement of the number of
processes in the run queue.
And surely you'd be able to find it at http://msdn.microsoft.com/library.
Thanks for pointing out where they can find the info.
A simple count of the number of processes with CPU usage> 0
(minus the system idle) process would be a good start.
Hardly.
This is surely a subjective opinion. You're opinion is "hardly". Mine is
"good start".
The challenge here is to actually collect the data for the
last 15 minutes, so you'd be looking either at some sort of service
process waking up frequently to sample the CPU state, or some unholy
and unreliable scheme where Cygwin functions go off and do that every
now and then before doing their actual job.
While any of the 1, 5 or 15 minutes would be challenging as you say
here, I still maintain that an instantaneous measure to substitute for
at least the 1 minute figure would be an improvement over just putting
out 0. You are free to maintain a different opinion just as I am free to
hold this one.
