Nagios Support Forum

Hi team,
We are looking for some information around Nagios Core.
1. Will nagios core has the functionality to integrate with HPE OMi?
2. Does Nagios core monitor HPE ilos? If yes, is it only upon installing AMS agents on its management servers?
3. Does it support hardware with all Gens?
4. Does it monitor servers with all OS types?
5. Does it support monitoring servers and storage systems?
6. Does Nagios core capture hardware failures like disk failure, power, controller battery etc?
7. Is Nagios core capable of event forwarding?
8. What is the capacity of nagios core (we mean how many servers can be monitored on a single nagios core instance?
9. Does Nagios core supports monitoring servers of all vendors (eg: HP, Dell etc.,)

An important thing to understand is that Nagios Core is a monitoring framework. It's not a one-stop shop that comes pre-packaged with everything you could ever possibly need. There is configuration work to be done in order to get Nagios Core to effectively monitor any given infrastructure.

If you want something that is more ready "out of the box", Nagios XI is a superior option but is not free.

The answer to all of these is yes; You can configure Nagios Core to monitor all of those things. Nagios Core is simply a framework. The plugins are what allows Nagios Core to interact with a particular piece of hardware, software, platform, toaster, blender, cat/dog/hamster, etc. More info on plugins:

If you want to know if a particular plugin has already been designed by members of the Nagios Community (for HPE OMi, for example), the Nagios Exchange as well as Google are good resources:

Yup! Notification Handlers are the most common vehicle for event forwarding:

Event Handlers are another option:

It depends on a wide variety of factors. The type of things you're checking, what plugins you're using to execute those checks, how often you're executing those checks, and other factors. I've seen machines using primarily compiled plugins handle 20,000 checks on a 5 minute interval without breaking a sweat. I've seen machines using interpreted plugins (Perl, PHP, etc) struggle to handle 5,000 checks on a 5 minute interval.

Dell has an official plugin for OpenManage:

There's a few community plugins for HP devices:

Thanks for the assist, @mcapra!

@vishalch07, let us know if you have further (related) questions.
