[Observium] Still get alerts on deleted interfaces / vinterfaces

Dear Observium members,

Monitored interfaces went down on our brocade devices, then we deleted the interfaces (because we didn't use them anymore). We are now facing a bug where alerts are still up and still send Email notifications, even if Observium sees the interfaces as deleted.

I have seen there is a "ignore until OK" button in the interface monitoring options but I want it out of alerts.

Question: is this a bug? If yes, has it been fixed? (long not upgraded the files).

Thanks!

Best regards,

Pirmin Sidler
