Nagios XI - Auto Discover

[GeneralCuriosity]

Hello

I am looking for an article or support document that outlines the Auto Discover capacity. I am aware that this function uses a combination of Ping and NMAP to discover hosts and that it leverages the same to provide details on OS, etc.

I am specifically looking for information, a list, of what all devices it is known to discover or what the Nagios official support stance on discovering and identifying is.

I have reviewed all support.nagios documents on Auto Discover and did not find these details.

Thanks in advance

Adding some additional detail. The NMAP website states it includes over 2600 OS fingerprints in the nmap-os-db from the devices below, but it does not have a specific table or detailed list to review.

• general purpose (windows and linux)
  bridge
  broadband router
  firewall
  game console
  hub
  load balancer
  media device
  PBX
  PDA
  Phone
  Power-device
  Printer
  Print server
  Proxy server
  Remote management

Does Nagios have a stance on the support of discovery or is it just whatever NMAP can pick up? In other words, is Nagios doing anything proprietary with the results to improve discovery beyond what NMAP provides?

Hi @GeneralCuriosity
Regarding the internal workings of Auto-Discovery that's really a developer question, but what I can tell is that you are correct, the component uses systems tools like namp, traceroute and ping to help discover devices on your network. It's an approximation as to the operating systems and services based on tests and public ports. Consequently, we don't have a position on what operating system or services it can accurately detect.

Hope that helps and let me know if you have any other questions.
