If it's Microsoft IIS, you can query the performance counter for
current connections using NSClient++.  In my nsc.ini config, I have:

 web_curr_conn=inject CheckCounter "Counter:connections=\Web
Service(_Total)\Current Connections" ShowAll MaxWarn=40 MaxCrit=100

So I can then query the counter from Nagios using a simple nrpe command like:

$USER1$/check_nrpe -H $HOSTADDDRESS$ -c web_curr_conn


Cheers,

Jim
