I just want to reply to my own thread here with an odd update..

Discovery:
There are a couple of devices that aren't getting discovered for some reason. The IP that their hostname resolves to is within the 'nets' arrays configured inside config.php and I have other SNMP devices that reach those boxes, so I know the SNMP side is sound. Likewise, I can see the device in question in the CDP table of an adjacent device, so I know that part is working as well.
I've looked at a ./discovery -d of an adjacent device hoping to see a clue about why the device is being skipped, but nothing is striking out at me.
Miraculously, last night, one of the two devices was discovered. All I can think of that I did that might have triggered something was to run ./discovery.php -h <adjacent_device> -d -- where <adjacent_device> is a) a device that Observium has already discovered and has been polling since last week b) was initially discovered as part of the ./discovery.php -h all that is run after the first ./addhost.php <seed_device> <community> c) is directly connected to the device that was not getting discovered.
There is still no change on the second of the two previously undiscovered devices. Interestingly enough, it too is connected to the same device that I ran the aforementioned -d discovery on yesterday which ultimately led to the first of the two previously undiscovered devices finally being discovered.
Any thoughts? Anything I can do to try to help troubleshoot this?
