Hi,
We are looking to monitor single Linux workstation(s) placed around the globe. We need to know that they have internet access and are online.
Does Nagios provide a client that sits on the device (Linux desktop) and reports out to a public IP across the WAN (a server with Nagios on it?)? What is the architecture?

Re: single system monitoring
Welcome to the forums!
In a general sense, you can see the architecture at https://support.nagios.com/kb/article.php?id=35
As for how the Linux workstations talk to XI, there are different ways to do it. check_by_ssh (https://assets.nagios.com/downloads/nag ... ng_SSH.pdf) is going to be the most secure, but there's also NRPE, and SNMPv3 (https://assets.nagios.com/downloads/nag ... g_SNMP.pdf). You can also supposedly monitor Linux with NSClient (https://www.nsclient.org/tag/linux/), but I am not aware of anyone with XI actually do that.
The XI Linux Wizard in XI uses NRPE. You can see the distros we support and details on setting it up at https://assets.nagios.com/downloads/nag ... ios-XI.pdf. One that to note is that you can also use NRPE if the two machines cannot directly talk. You can find full NRPE documentation at https://assets.nagios.com/downloads/nag ... e/NRPE.pdf. There are other ways to deal with firewalls and proxies, but you didn't ask specifically about that, so I will spare you the details.
Please let us know if you'd like additional detail. We'll be happy to help.
