Hello! Subscriber here... One of our Observium instances has stopped alerting on the port down alert/checker. Specifically, it will still alert in ports we had configured already when this instance of Observium was installed, but it will not alert on any new ports we configure/add to the infrastructure. I.e. switch1 port1 was set up right after install, tested, good, and still alerts if it goes down. switch1 port2 was added to observium at a later date due to a new server install, and if it goes down it will not alert. We had 8 switches at the time, and this behavior seems to be equal across all 8 (not had time for thorough testing, which I would normally do except for the discovery of the below error).
It has been going on for a few months that we know of, but this has not yet bubbled to the top of our list of things to tackle. But we are now adding new infrastructure to that particular datacenter, and while I am mucking about there I thought I would take a look.
I found the observium and housekeeping logs seemingly normal, but the db log is full of the below error (and nothing else):
[2023/01/17 22:53:56 +0000] index.php(40131): Failed dbQuery (#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'AND 0 GROUP BY `group_id`' at line 1), Query: SELECT COUNT(*) AS `count`, `group_id` FROM `group_table` WHERE AND 0 GROUP BY `group_id`
I thought this may have started when I did an update several months ago, but it is possible it has been doing this since inception. I did do an update today, thinking perhaps I missed running discovery.php -u when I did that update, but alas that did not help.
Help please. 😀
