I have 2 Palo Alto firewalls which dropped off the map at the same time about 25 days ago. I think it may have coincided with an Observium upgrade; but I didn't write down update particulars and I don't think Observium maintains a history?
When I run discovery with debug there is a SQL query posted (which fails) attempting to lookup the device:
SQL[SELECT * FROM `devices` WHERE `disabled` = 0 AND `hostname` LIKE 'vpn01-p.{redacted}' AND `status` = '1' AND `poller_id` = '0' ORDER BY `last_discovered_timetaken` ASC]
In this case, the query fails because "status" is actually set to 0.
So what is the "status" field for in the "devices" table and how is it set 'wrong?'
There is a "statuses" tab in the web GUI for the device's "properties", but in this case (a PAN firewall) there are 2 MIB entries for indicating the fail-over status of the device pair ("HA State" and "HA Peer State"); so I don't think they have anything to do with the "status" field in the DB.
