I believe this can be marked as resolved.
All of our devices were listed as offline this morning, which was caused by the following: http://www.observium.org/wiki/FAQs#All_my_hosts_seem_down_to_Observium_.2F_S...
I followed the guide, and removed .index from the noted directory.
As soon as I did that, everything started polling again. At around the same time, I also found this: http://www.observium.org/wiki/Poller-wrapper.py
Our poller was set to use 3 threads, so I bumped it up to 12. After review, I found that my alert checker was now listing devices as checking in and passing the offline test. I faked an outage on a test device, which triggered the e-mail alert.
Thanks again for the assistance on this. I'll have to dig into the snmp bug a little bit, but all is now working as it should.

Tom,
Thank you very much for looking at my configuration. I failed to note earlier, that I receive the same results when I change the delay of this alert back down to 0.
For the sake of my own sanity though, I went back and changed it just now. I triggered a false device outage, which failed to trigger the alert.
Something odd I am seeing, is that Observium is now listing 8 devices as having passed the alert check, with 464 devices still listed as never checked.
As you can see from my screen shots earlier, that the alert checked never listed any devices as having been successfully checked. They were all greyed out.
As you've confirmed that the alert checker is configured correctly, I'm somewhat stumped.
I'll keep digging, as this is a feature I'd really like to get working.
Side Note:
Our CPU and RAM are not hitting 100% utilization on our host, so now I'm suspicious of we're just pushing the Observium platform a little too hard.
There are occasions when loading Observium takes longer than expected. When I create a new alert and regenerate them, the page seems to timeout.
(I've included the graphs of our disk I/O, as It's been suggested before as something to keep an eye on.)
Any other thoughts or insight on this would be greatly appreciated.
Thanks again for your time on both the project and on this thread.

Hi Nate,
You set the "delay" to 1 which means Observium will wait 1 extra poll to see if the alert condition restores itself (which it seems to do judging by your alert log - hence no alert).

Good evening all,
After much trial and error, I?ve been unsuccessful in implementing a
simple up/down device alert within Observium.
As I searched around the web for a solution, It seemed as though this
hasn?t been much of an issue for most users.
Here?s some additional documentation I followed to try and fix it myself:
http://www.maartenmoerman.nl/?p=612(Nice work on this one)
https://www.mail-archive.com/observium@observium.org/msg05915.html
I?m starting think that my configuration file (config.php) could have
something to do with it. I?ve included it, along with multiple
snip-its to try and assist you in seeing my work.
If anyone has any suggestions on this, they would be greatly
appreciated. I?ve been working on this on and off for the past few
days now, and I?ve had no success in generating an offline alert.The
alert log shows the test as failed, but delayed. It never actually
send out an e-mail. My apologies in advance, if this turns out to be
user error.
Thanks in advance for any time put into this. If there is anything
else I can provide to further assist in troubleshooting, please let me
know.
I?d be more than happy to provide it.
*Omitted config.php:*
*?*
// Enable alerter
$config['poller-wrapper']['alerter']= TRUE;
// Disable page refresh

$config['email']['default_only']= TRUE;
$config['email']['enable']= TRUE;// Disables OLD alerting system
