On a recent install of observium, I’ve noticed some oddities with Syslog collection… Some devices are being collected just fine, but others are not. 

In the example screenshot included below, my firewall ***10, and one switch ***04 are both being collected just fine. But the switches 75***** and *****50 are not.

One thing I noticed was that someone had turned on “service sequence-numbers” on the ****04 switch. (The ASA has no such feature that I know of.. ) When I disabled this service, the collection stopped working on that device! Example here…http://i.imgur.com/HViWcTk.png

Thoughts? Thanks!!
