Discover new devices not including in monitored devices?!

[xpertech]

Is there any tool which I can discover new devices connected to network and not including in already monitored devices?

arpwatch is a simple tool which sends email notifications for new devices that show up on the network. It records IP, MAC address, and NIC vendor if it recognizes it.

Otherwise you an also run the auto-discovery wizard periodically against certain subnets, this will only detect open ports to monitor as well.

Thanks for the reply. I prefer using Nagios XI plugins or wizards, but auto-discovery wizard can only find new hosts in the moment I run it, what I want is Nagios XI plugin or wizard can auto find new host and send Email alert. The check_find_new_hosts seems good to me, but hard to configure... (http://exchange.nagios.org/directory/Pl ... ts/details)

xpertech,

You could use check_logfiles to monitor the logfiles created by arpwatch.

Heres a document describing how to configure host and service emails (which would be your check_logfiles service)
