put the ip's in the local host file or register them with reverse dns.

i bet your other ips have reverse dns setup for them so the server can convert the ip to hostnames.

/etc/hosts

192.168.168.168 my.hostname.com

device ip [space] desired hostname

match the hostname to what is in observium.

syslog only works on ip's and needs to reverse them to find the hostname.

Spent hours on this and am at a loss.

Got some hosts that won't have syslog show up in the GUI, digging further the DB shows the IP not the hostname for those records, so that makes sense why they are not showing up.

Looking at the actual data coming over syslog the devices that work and don't work show the exact same format. Nothing different at all, and identical configs on identical devices.

Is there a debug or another log that I am not seeing that would show why these entries are getting inserted into the DB as IP addresses and not being replaced with hostnames?

At a loss, any suggestions would be great!
