How to add Linux hosts

[lgitten]

I'm new to nagios.
I successfully installed Nagios XI on my monitoring Linux PC.
Now I want to add my Linux hosts (servers) that I want to monitor.
Monitoring Wizard does not have an option for "Monitoring Linux workstations and servers."
Do I need to download it separately by clicking "More Wizards" and then install?
I want to monitor my blade servers P710 and P610 and standalone servers.
Does it mean I need to download both "Dell OpenManage Wizard" and "Monitoring Linux workstations and servers" wizards?
Can't I manually add new hosts by discovering their IP's and without the need to download additional wizards?


Thanks.

You can monitor your linux hosts via NRPE, SSH or SNMP.
Here is some information on each option:
NRPE
First, you will have to install an agent on the client machine:

Also, see this:

Next, you run the Linux Server Monitoring Wizard: Configure->Run the Monitoring Wizard->Linux Server
If you don't have it installed, you can click on "Get More Wizards", or just go to:
http://exchange.nagios.org/directory/Ad ... rd/details
and download the wizard. You install it by going to: Admin->System Extensions->Manage Config Wizards->Browse->Upload Wizard

SSH

SNMP

Hope this helps.

I decided to go with SSH option and used the link below provided for SSH.
However, when I downloaded SSH Wizard from the link provided, I unzipped it and placed it in a folder /tmp/nagiosxi/
When I open my Nagios XI list of wizards web interface, I don't see ssh wizard in the list.
How do I install this wizard since it only has config files when you unzip it? Isn't copying it in /tmp/nagiosxi/ folder is not enough?

Thanks.

You should not unzip the file - just download it to your local machine. From the Nagios XI web interface, click on the "Admin" menu, then click on the "Manage Config Wizards" under "System Extensions" from the left panel menu. Click on the "Browse" button, locate the file you just downloaded ("sshproxy.zip"), double-click on it, and hit "Upload Wizard". That's it. The SSH Proxy wizard is installed. In order to use it, go to: Configure->Run the Monitoring Wizard->SSH Proxy.
