Simply looking for a way to display a list of users currently connected to the Orion web console. Would be nice to know who I'm about to disrupt when performing maintenance.
I don't think you can get the individual users at the server level, but you can user perfmon counters to get counts of how many active connections there are.
For IIS6 (from the Technet Article):
1.Open Administrative Tools, and then click Performance.
2.Right-click the System Monitor details pane, and then click Add Counters.
3.Do one of the following:
To monitor any computer on which the monitoring console is run, click Use local computer counters.
-or-
To monitor a specific computer, regardless of where the monitoring console is run, click Select counters from computer, and specify a computer name or IP address.
4.In Performance object, click:
Web Service to monitor active Web connections.
FTP Service to monitor active FTP connections.
5.Click Select counters from list, and select Current Connections.
6.Click All instances.
7.Click Add, and then click Close.
