Thanks for your reply.
By the way, is it enough to monitor the condor_negotiator service to
summarize the workload/performance of the Central Manager during
matchmaking? Based on my understanding that the condor_negotiator is the
most related to the matchmaking activity while condor_collector is only
used to collect the classAd in the Condor pool.
Appreciate of your advice. Thanks.

You actually have 4 cases to measure:
Case 1: Simple job ad, simple slot ad
Case 2: Simple job ad, complicated slot ad
Case 3: Complicated job ad, simple slot ad
Case 4: Complicated job ad, complicated slot ad
And even that is...uh...simplifying the measurement cases considerably.
For Case 1: Create a slot that has no restrictions on. Create jobs that
have no "Requirements =" lines in them that you know will match to the
For Case 2: Make the Start expression and/or the Rank expression on the
slot something funky with time-of-day logic and username logic. Use the
same jobs as in Case 1.
For Case 3: Add a Requriments string to your job ad that looks at only
Condor-default attributes on a machine. Use the same machine ad as in
For Case 4: Same job ads as in Case 3 but now add in the machine ads
from Case 2. Maybe define custom attributes on the machine and match
against those in the jobs.
Sky's the limit on how "complicated" you want to get with the
