Nagios Support Forum

Hello,

My network admin came to me and asked the Protocol and port Nagios XI (server and client) uses. I have installed the agent NSClient++ on some Windows server 2000, 2003, 2008 with modules common check plugins, Check_nt.

He is very worried that if we add a lot of nodes, this will cause a network problem.

Can you please point me to the location where I can find this information?

Thank You in advance

This is the great thing about XI, you can choose...

The standard XI utilized 80/443 for the web UI and you can use active agents such as NSClient which by default listens on 12489 for check_nt but this could be changed.

Additionally, you do not have to actively check, you can passively send the data to XI via NRPD (port 80/443) or NSCA (port 5667) just on the XI server.

Another common port used for active checks is 5666 for NRPE.

Really in XI there are countless ways to setup your monitoring and you get to choose which methods to use, and which not to.

Another way to setup the check to be sent passively from your remote machines to your XI server is to use Admin -> NRDS Config Manager which will passively send the results to XI server using standard port 80 or 443 (outbound from remote client).

NRPD or NSCA support Windows ?

Yes both are fully supported for use on Windows systems.
