Nagios Support Forum

Hello Team,

Can we monitor one server on two Nagios servers?
We have two Nagios instances, one is Nagios Core and other is Nagios XI. We want to monitor one Linux server on both the Nagios XI instances.
Is it possible?

If yes, what all config changes will be required?

Hi @kalyanpabolu,

Nagios XI has the ability to set up inbound and outbound transfers between servers. The incoming checks would be received as passive check results using NRDP (Nagios Remote Data Processor).

Nagios XI Configuring Outbound Checks

Nagios Core does not have NRPD installed by default, it would be necessary to install and configure that as an addon. This would be outside the scope of Nagios XI support, however, we do have documentation on setting this up.

Let us know if you have more questions.
