Frequently Asked Questions
What's going on here?
This web site allows you to upload log files generated by
the Condor distributed computing system,
and get back graphics and an explanation of what happened in the system. This can aid in understanding a workload of hundreds or thousands of jobs. Here is an example of the output.
How do I create a user log file?
Add this line to your Condor submit file: log = userlog.txt
How do I create a machine file?
Run this command: condor_status -l > machinefile.txt
Why are you doing this?
We are constructing new tools that help people to debug distributed systems. The problem is, we need lots of log data to test our ideas on. So, if you upload your log files, you get (we hope) a useful result, and we get more data to practice on.
Will others be able to see my data?
The URL of your results is based on the checksum of your logfile. So, if you want to share your results with others, you can simply send the URL to your friends. If you do not want others to see your data, then don't publicize the URL, and it is highly unlikely anyone could guess it.
Can I download graphics and logs to use in my own papers, presentations, etc?
Yes, go right ahead. We would appreciate it if you give us a credit with the following citation: Douglas Thain, David Cieslak, and Nitesh Chawla, "Condor Log Analyzer", http://condorlog.cse.nd.edu, 2009.
