Nagios - configure a service

Описание: In this video, I’ll explain how to add a service for monitoring in Nagios.

I will cover the various parameters you can set for a service and a service template. Additionally, I’ll demonstrate how to add monitoring for this service to a host that is already configured in your Nagios system.

I invite you to check out my Nagios playlist for a complete list of all my videos on Nagios:
   • Nagios  

You can use your preferred text editor to modify the configuration files. In the video, I use vi, as I am very familiar with it, but other users may prefer nano, which is generally easier to use than vi.

Here are some commands I use in this video.

To navigate to the Nagios objects directory:
cd /etc/nagios4/objects/

To list the contents
ls

To open the service.cfg configuration file previously created in another # video.
sudo nano services.cfg

An example configuration to add:
define service{
use generic-service
hostgroup_name web-server
service_description monitoring port 80
check_command check_tcp!80
}

To view and modify the templates configured in your Nagios environment.
sudo nano /etc/nagios4/objects/templates.cfg

To configure a dedicated file to store host groups:
sudo nano /etc/nagios4/objects/host_groups.cfg

An example of configuring a host group.
define hostgroup {
