I want to monitor the number of active sessions in our terminal servers (windows 2003) to see how many users are logged in.
Terminal servers have nsclient++ 0.3.8 installed and whit the others check_nt services all work fine.
From the shell I've tried whit this command:
@host:/usr/local/nagios/libexec$ ./check_nt -H 192.168.0.19 -p 12489 -v COUNTER -l "\\Terminal Services\active Sessions" -w 35 -c 50
But the result is always "0" (there are user on the terminal server instead).
How can I do?
