Checking the Security log for successful logon events might work. You may need to turn on extra event log auditing for this.

if you're looking for a specific person/login, use the description filter, it should contain the user logged in and you can alert off the user's login. If you just want a list of who logged in set up a report for the week, either way as Ben said you'll need to turn on the eventlog for that to work.

That Is fine, I have enabled auditing but the issue is if you restart the service, it is also treated as a log on and alert is generated.  I need to mointor ONLY Logon types 2 and 10. which are for console and RDP.
