iis site Maximum Concurrent Connection Specifies the maximum number of connections for a site. Use this setting to limit the number of simultaneous client connections.
So when I set the value to 2 it will not allow more than 2 connection and give 503 error.below is the snapshot:
performance monitor shows the currently active connection with the time:
You can also get by using the below Powershell command:
Current Anonymous Users – the number of anonymous IIS users
Current Non-Anonymous Users – the number of authorized IIS users
Current Connections – total number of active connections on the IIS server
the information about the number of user sessions in the Performance Manager console is being displayed in real-time (by default, the counter values are displayed as linear graphs). If you select any of the counters in the bottom pane, you can view its last,
average, minimum or maximum value for a given period of time.

Viewing maximum number of IIS connections in perfmon

In IIS-10, I have set the `maximum concurrent connections` to 50, however, in the performance counters, I don't see that 50 for the related counters.

Which performance counter is related to this limit then?
