Specific Actions Auto-Discovery in XI Takes?

[matt.uebel]

I am interested in using Nagios to auto-discover frequently as a way of ensuring all our hosts are monitored. It seems that the auto-discovery plugin uses nmap to actually do the discovering part. Has anybody else used this method with success?

What specific nmap command does the plugin end up running?

I am having difficulty finding any documentation apart from initial setup and basic usage of the plugin. Does anybody have a link to good documentation?

The nmap commands are in a protected component, but the commands are:

Code: Select all

sudo /usr/bin/nmap -O -oX <filename> <ip>
/usr/bin/nmap -oX <filename> <ip>

And it also uses a vanilla traceroute command as well.

[matt.uebel]

So it will do a full port scan on each discovered host?

[abrist]

By default, Nmap scans the most common 1,000 ports for each protocol.

Is there any way to stop Nagios Auto-Discovery from doing this?

[abrist]

What would you like it to do instead?

[matt.uebel]

Do ping only for host discovery.

At this point it is not possible, as this is an encrypted file within XI. You certainly can put in a feature request, although something more along the lines of "Allowing additional scan options for nmap, such as ignoring ping up or down, udp scan...." Instead of just asking for the ability to only ping.
