Nagios Monitoring TMG


I have configured a CentOS 6 server to run Nagios to monitor our servers health.

It works on all server except that running the TMG.

I get the error CRITICAL - Socket timeout after 10 seconds from Nagios.

Nagios uses NSclient++ on port 12489 to communicate with servers.

I was wondering if anyone could help me configure the rule to allow Nagios to communicate with the TMG server

I worked it out.

The rule i created is as follows

First i created a protocol called Nagios Client. I configured the protocol to have the parameters

Port 12489 TCP Outbound
Port 12489 UDP Send Receive
Port 5666 TCP Outbound
Port 5666 UDP Send Receive

Then i created a network object for the Nagios Server containing its IP.

After this i created a new access rule to allow connections from the Nagios Server to the local host using protocol "Nagios Client" (The one i created) with condition all users.

My Nagios server can now connect to the TMG
