Nagios Support Forum

Hi,

I deployed Nagios core server version 4 in Cloud(Microsoft Azure).I able to monitor the cloud servers.
I would like to monitor the on-premises servers.
There is no public ip address for on-premises servers.Is it possible to monitor?
Kindly give the suggestions


Thanks

Here are just a few of the many options for this type of scenario:
1. You can use an active agent that can bind to different ports. nrpe can run on different ports. . .
2. Alternatively, you could use a single nrpe server as a proxy for all checks on the network - this would only require 1 forwarding rule.
3. Another option is to set up a vpn/ssh tunnel for the checks - just make sure your routes are right.
4. Passive checks could be used and would not require any ports forwarded . . .

For the sake of simplicity, I think you should start out looking at passive checks. We don't support Core commercially, but since XI is built on top of it, we kinda do. The other two methods really take you away from what we are able to support. Here is the passive checks document for Nagios Core 4: https://assets.nagios.com/downloads/nag ... hecks.html. Please let us know if you have any additional questions.
