As this isn't a plugin we wrote, it's a bit difficult to troubleshoot.

Have you taken a look to see if any other plugins will work for you? I was able to find this one -

Another option, could you look at your performance counters and see if you can monitor Terminal Services -> Active Sessions? You may be able to pull the active connections from there as well.

I wrote this script a few years ago.

the script works in Windows 2008, WIndows 8, but it doesn't work in Windows 2012

I had another user report this issue some time ago and they also had Windows 2012. I tried to help them however it seems as though the object the script is referencing no longer exists in the WMI class. I no longer work with Remote Desktop Servers so I have no interest in updating it.

If you weren't interested in the bytes information, you can comment out lines 398 - 430.

And replace line 494 with:

Code: Select all

FinalOutput = "Sessions {Active=" & TotalActive & " Idle=" & TotalIdle & " Disconnected=" & TotalDisconnected & "} |'Active Sessions'=" & TotalActive & " 'Idle Sessions'=" & TotalIdle & " 'Disconnected Sessions'=" & TotalDisconnected & " [get_rdp_info]"

I think that'll work.

Also, if your operating system is something other than english ... then I would give up as the sessions stuff isn't going to work either.

that eliminated the errors,


but still doesn't give me the session count which is what I really want

Another option, could you look at your performance counters and see if you can monitor Terminal Services -> Active Sessions? You may be able to pull the active connections from there as well.

Are you able to see the active # of connections through the performance counters?

[bosecorp]

Yes, I can.

what changes would need to be made to the script

[Box293]

The script uses this command to get the connection details:

Code: Select all

qwinsta

What is the output of that command in a dos window?

[bosecorp]

The commands shows the active sessions

[rkennedy]

We didn't write the plugin for the Windows RDP sessions, so it's hard to say why it's not working.

If you can pull the information from performance counters as you mentioned, it may be easier to go that route.

[Box293]

Performance counter is probably going to be easier.

These guides should help:
