Unknown means the device hasn't been polled yet since the alert check was updated, which might mean it's offline/unreachable, which might mean your original alert was fine. I'm guessing there is an ACL or other issue preventing your Observium server from getting ICMP and/or SNMP to these devices.

Try to ping one from the observium server, and do a manual discovery on one to see if it can be reached, I'd bet they can't.

You can delete it and recreate it or just fix the broken conditions.

This device isn't "showing down", an alert that you've called "device up/down" which may or may not correctly track a device being up/down has failed for these devices, seemingly all of your devices.

It's most likely that your alert conditions are broken and are just always returning failed.

Hi Team,

We have problem with device alerts. Due to this we can't monitor our network. Actually, our devices are online but, in the alerts, it will be showing down. I have tried to forceful discover but still same. I think it will be software bug then i will update to latest version but at here also same issue. If anyone have solution, please let me know. Thanks in advance.
