Re: [HTCondor-users] Core usage of cluster

	Unfortunately, as far as I know, there's no built-in core-oriented 
reporting.  To sum all CPUs allocated to running jobs:

condor_status -const 'Activity == "Busy"' -af Cpus | awk '{total += $1}END{print total}'

	To sum the actual CPU usage of those running jobs:

condor_status -const 'Activity == "Busy"' -af CPUsUsage | awk '{total += $1}END{print total}'

	You can get a lot fancier:

condor_status -const 'Activity == "Busy"' -af CPUsUsage Cpus | \
	awk '{usage += $1; total += $2; jobs += 1}END{print jobs " active 
jobs are assigned " total " CPUs and are using " usage " of them (" (usage / total)*100 "%)" }'

	and get output like

32 active jobs are assigned 32 CPUs and are using 29.428 of them (91.9625%)


	The following monster generates a line more like the one in your 
example:

condor_status -af Activity CPUsUsage Cpus | awk '/^Busy/{usage += $2; total += $3; jobs += 1}{pooltotal += $3}END{print jobs " active jobs are assigned " total " CPUs (out of " pooltotal ") and are using " usage " of them (" (usage / total)*100 "%).  That is " (total / pooltotal) * 100 "% assigned and " (usage / pooltotal) * 100 "% usage." }'

	giving output like

13328 active jobs are assigned 14688 CPUs (out of 15636) and are using 
13643 of them (92.8853%).  That is 93.9371% assigned and 87.2538% usage.


	Note that using 'condor_status' to get the data gives a slightly 
different view of things than using 'condor_q' (if you have any jobs that 
aren't yours running on your cluster, or if you're running any of your 
jobs on somebody else's cluster).  It should also be faster, but it could 
be a few minutes out of date.
