[Condor-users] Condor and monitoring performance

I was curious if anyone has suggestions on how to monitor the health of a Condor pool? I am trying to track down an error (Q3) and was also trying to develop a set of commands for monitoring Condor.

1. I found this URL, which is helpful but there appear to be some issues for windows.

I noticed that the binary for condor_updates_stats does not exist with window installations of Condor. Is this a mistake or is it not available with windows?

2. Does any one have suggestions for querying Condor to help detect potential issues with performance?

3. I am getting the following error and I am not sure how to determine if I need to modify my configuration or whether there is something else wrong.

4. Occasionally I get an error when I use condor_status or condor_q, which I believe is related to the errors in Q3. Failed to fetch ads from ...

Thank you for your suggestions,
