Nagios XI 5.6.6

I have added 15 or so domain names that we own to be monitored in Nagios XI using check_domain.php. I added each domain name as a host and the whois works fine. If I add services, I immediately receive Unknown alerts. I create a host group for our domains and called the group DomainNames. I then added the 'hosts' to the group. They will not, however alert when warnings or criticals occur (due to them being hosts?).

Can I add warnings and criticals to just these specific domain name 'hosts' either individually or via the host group? I want to stay away from creating services for each of these, as they each show Unknown alerts. I am currenly limited on what I can specifiy for criticality.

Hi Randle,

In Nagios, there's a difference between host states and services states. A host is a device with an IP address and can be in one of three different states at any given time.

* Up
* Down
* Unreachable

While a service is associated with host and can be in one of four different states at any given time.
* Ok
* Warning
* Critical
* Unknown

You can add a critical threshold for the host check, but it will either be up or down. If you would like warning/critical thresholds for this check, you'll need set it up as a service.

More information available in the Nagios Core documentation.

Let me know if you have any other questions.

Thank you Benjamin. Makes total sense. Feel free to close this thread with my thanks.
