SB EventLog Monitor

On the Monitored Computers and/or Eventlog page have it show the last
successful collection time.

I use the Eventlog page to see the errors on warnings on each computer. I
filter out the successful audits and information events. I'll look at each
computer individually. If there aren't any recent errors or warnings I
don't know if the collection didn't succeed or if there actually weren't
any errors/warnings.
