Hi, 
We are using observium 22.12.12421(stable) over a centos 7 (php 7.0.33), but we have a something problems on tables or alerts.
First: on device properties -> ports, the items (vlan and physical interfaces) are showit order by ifIndex not port name or description, screenshot a Aruba Procurve 2530

Second: in same table, does not showing all ports. that mean on many devices does not show port 1 or other port, but in the summary of ports detail the same port are show correctly. this do not allow to enable notifications on the port.

On referent to first issue (may be): some alerts warning about a port down, but really port down does not exist or other port is down. 

we must update version?
