Monitoring across multiple networks

[Eniyan]

Hi Team,

We have multiple NW zones, Infrastructure systems in Zone B and Zone C are already being monitored using Nagios XI.

Zone A is a new setup and we need to monitor Zone A systems using Nagios XI instance in Zone B. What are the best practices to do it!

Generally speaking you would need to provide access to Zone A from Zone B using something like a VPN or allowing through firewalls. This is very generic, as we can only guess at how these are connected

Hi,

We use a jump host to connect to Zone A. Zone A is segregated on purpose.
We are looking for solutions on monitoring segrated networks like setting up a proxy, distributed monitoring or any better solutons/practices that Nagios can suggest. Thanks.

Does Zone A have outbound access to the other networks? Can it send data?

[Eniyan]

Zone A has access to other networks, but with restrictions. Based on the need and requirement we can make a request to allow by creating rule in firewall. Thanks.

One possible solution depending on the types of machines you are monitoring would be to setup the machines to send passive results to your Nagios XI server in Zone B using something like NRDS. These would be all outbound from Zone A

Thanks. We will give this a try a write back with our observation.
Also in passive checks, to add/modify a service or change alert thresholds, should we just edit the NRDS config or is there something to be done on the client side. Thanks.

You just edit the config in XI and it will update on the clients the next time they send results
