How do I get information on completed jobs?

A: Use the condor_history command for jobs completed during last two days.
You might find useful information on resource consumption also in job log files (CPU usage, memory usage, disk usage, etc.).

condor_history <username>
condor_history -long <Job_ID>

The Golias farm automatically sends a weekly summary of jobs that finished during the past week (CPU/memory/disk usage, efficiency) on every Monday morning.
You will receive also an e-mail notification in case your jobs have an efficiency lower than 30 percent.
More detailed information is available at Automated E-mails from the Golias Computing Farm.
