Ports monitoring

[abdelilah]

Hello everyone,

Could you please tell me if there is a way to monitore active connections and ports on a remote windows machine via snmp or nsclient, I have searched in the plugins libray but all I could find was useless to my case.

Thanks in advance.

You can definitely monitor port status and to some extent activity with either source of monitoring. When you say active connections, you are looking to continually monitor the total number, each individual one, or for a specific connection?

For example by typing "netstat -bn" I obtain this (among many others):

[Dropbox.exe] TCP 192.168.1.96:25718 108.160.163.51:80 ESTABLISHED

I want to be able to monitor this connection in the remote windows machine from Nagios.

Well, sure you can write a script that will output the results of this command, count up the number of connections and allows you to check warning and critical amounts. Otherwise this plugin might work for you:
