check_con

I wrote a simple plugin to check the number of established connections
to a windows server. Just execute:
cmd /c netstat -an |find /i “estab” /c

I have also done the same for a linux server. Just exec.:
netstat -anp | grep -c EST
In fact that script is only 2 lines:
result=`netstat -anp | grep :81 | grep -c EST`
echo “Conexoes Totais = $result |Conexoes=$result”
Note that | will graph that result, witch is very usefull!

There are many ways of getting that information, I have also
done the same thing via WMI, perfmon has that counter
and it maybe easier to for example find out the total number of
current connections to a specific website.

The script for windows is a .vbs and I call it using NC_NET
