It's definitely limited. Goal was to only show already available/easy to reach additional info.
@Tom When hovering with mouse over mac address in device > port > FDB table, eth board manufacturer is show in a popup. Patch adds IP and DNS name to the popup.

And especially since this is only really useful for ports the observium server itself can see, it's of very limited usefulness.

only convenience - I don't need to ssh and grep 'manually'. Usage scenario would be something like:
- "slow internet" complains
- one edge port has high utilization.
- MACs on the port are show
- If also PC IP/name is shown (hopefully with descriptive name), you
can immediately see who is the problematic user.

I'm not sure how useful it is to get information about the hosts that the Observium server itself can see at layer 2.

Hi
I here and there search for IP address belonging to certain MAC address. Below is a tiny patch to show that info in observium. Data is read from arpwatch datafile (path to datafile is set in config.php): // enable arpwatch $config['arpwatch']['datafile'] = "/var/lib/arpwatch/arp.dat";
And once IP is known, reverse DNS name is informative too. Patch acceptable for inclusion?
