Nagios Support Forum

Hello everyone,

For our company we are looking at Nagios to create a distributed monitoring system so we can monitor our customers. I did a test case with 2 Nagios Core versions and this works just fine. Now i have a couple questions though.

1. Does Nagios Core xi support the Nagios Core as slave?
2. Does the Nagios Core xi also need all devices and services added just like the normal Nagios Core setup or is this propegated to the main central.

Sure, its typical to setup the Nagios Core instances to push the results passively to Nagios xi, which Nagios xi will catch and will put in the Unconfigured Objects, which you can setup from there. So,

1) Yes
2) Yes, but it is pretty easy. Now if you're talking thousands and thousand of hosts, services, you'll want to generate a config, but if you're starting off from the groundlevel doing this, using the Unconfigured Objects method is pretty slick.

Regarding question number 2. I am actually guessing that i will only need todo the services once. Since all customers get there own host groups i will have to just attach them to the same hostgroup and then i only need to add the hosts.

Can you specify a bit clearer what you mean with generating the config? The only thing i found i to import the older Core configs. I tried that with the live cd and for some reason all got messed up.

Considering that most clients only have max 10 hosts which will share about 90% of the services i am guessing the unconfigured objects is a pretty fast way todo it.

Yeah, unconfigured objects sounds like the way to go here, in case you had not stumbled upon it, here is the documentation on unconfigured objects:

By generating the config I mean writing it out by hand much like you would with Nagios Core, but thats pretty much was the Unconfigured Objects wizard is going to do for you.

Thanks for all the answers. Gonna try it later on.

I have been working for most of the day with the unconfigured object to see what they do etc.

Some things gave me questions though.

1. When importing the device it also imports the services but when you check the service it has no check command added. Is this normal or do i manual have to add those later on.
2. I have a PING service configured on all hosts but for some reason the unconfigured objects still show PING as a not added service for most hosts. Is this a bug?
3. It seems the unconfigured host page is unable to remove hosts when you want them to be deleted. I did see this on the forum aswell for someone else. Is there still a way to get this page to clear up?

The services utilize the xi_wizard_passive_service template (I think), so it would use whatever command is defined in that. If it's not defined there, you could add it to have a default check for all passive services.

2. I have a PING service configured on all hosts but for some reason the unconfigured objects still show PING as a not added service for most hosts. Is this a bug?

Not sure, can you show an example service config from the active server and also what you're getting from the unconfigured object page? I want to make sure we understand your scenario.

I think this is still a bug in this particular component...
