I believe you want OS information, SIM can detect diskspace, CPU load and general OS information. You could create a script that could show the users logged on to a machine or a group of servers but to create a overall view, that's a whole other thing. You can't store this information in the SIM database.
Any other tool could the same, HP Rappid Deployment or Altiris (both the same tool) could also do this. You are looking for a tool that could run such a tool on all of your servers and write the result in a file on a shared disk. That do you math and sort on users. But all of this has nothing to do with SIM. You can use the credentials in SIM to query your servers but the script itself you'd have to create yourself. You could also look in the script forum for SIM or ask your question there.
