Adam helped resolved the issue. Document here just in case anyone seeing the same issue.

Wow thank you so much! That was it, the new server has a difference fping path.

/usr/sbin/fping was on CentOS
/usr/bin/fping is on Ubuntu

All,

I'm kind of hitting a wall here. I moved Observium to a new server today and somehow Observium is unable to "ping" any hosts.

sour% ./poller.php -h lab-lightning.sdsc.edu -d         
Observium Poller v0.13.1.3507

DEBUG!
Starting polling run:


SQL[SELECT `device_id` FROM `devices` WHERE `disabled` = 0 AND `hostname` LIKE 'lab-lightning.sdsc.edu' ORDER BY `device_id` ASC] ./poller.php lab-lightning.sdsc.edu January 3, 2013, 17:17 - 0 devices polled in 0.001 secs

MySQL: Cell[0/0s] Row[0/0s] Rows[1/0s] Column[0/0s] Update[0/0s] Insert[0/0s] Delete[0/0s]

However, on the host it self, I can ping or snmpget any devices using the same FQDN name.
