If you're looking for a paid, supported solution, there's nothing much better than Nagios XI . Nagios XI only manages a single core instance though, not multiple. Nagios Fusion can offer an overview of multiple Nagios Core/XI instances, but not consolidated management of all of those instances. For ...

I would strongly suggest creating this as a cron job or dedicated process/daemon instead, then submitting the results to Nagios Core as a passive check . Nagios Core wasn't really designed around this level of granularity. The interval Nagios Core uses is contained in the main cfg file as interval_l...

Can somebody explain to me how Nagios XI can be scaled? The hardware requirements page is a good place to start: https://assets.nagios.com/downloads/nagiosxi/docs/Nagios-XI-Hardware-Requirements.pdf Strictly speaking, it depends. If you have 1000 checks that all require traversing entire SNMP trees...

This process is pretty well documented and supported: https://assets.nagios.com/downloads/nagiosxi/docs/Migrating-From-Nagios-Core-To-Nagios-XI.pdf I'd recommend moving everything over to a completely new VM with a fresh installation of the latest Nagios XI version. Let us know if you encounter spec...

Did you follow the steps detailed in the official documentation for setting up the WMI service user? https://assets.nagios.com/downloads/nagiosxi/docs/Monitoring-Windows-Using-WMI-and-Nagios-XI.pdf Are you using a domain user? Are you providing a DNS record when connecting to the host, or using an I...

It looks like all you have for configured repositories are the local installation media, EPEL, and a custom repomd.xml file that the system is unable to read from some custom mount. Is it possible that this system is trying to reference some internal repositories for your organization that were not ...

The issue I am trying to solve is notifications get silenced due to work, or an outage but then they are simply forgotten and left disabled It's better to put the particular problem into a downtime state if you want to temporarily silence notifications, IMO. downtime.PNG Say after 48 hours re-enabl...

At a high level, what I think you want to do is have a custom notification handler -- one that both handles your emailing needs, and one that could dump the notifications to some other service. In this case your service is Splunk, but it could be a generic logfile to be consumed by a Splunk forwarde...
