Deployment Solution

Is there a log for jobs that are run? I'd like to be able to audit server imaging but cannot find an easy way to do it. Perhaps a database table? I'm not a database person but have some colleagues that will help.
Also - how can I audit who logs into the DS and runs jobs?
DS 6.9sp1

There is a history in DS that logs job information, including the user that ran the job.  If you have the Deployment Solution installed and configured in NS, I believe there is a report in NS that will give you this information.
