I’ve a problem with alert notification.
I’ve an alert rule like ports.ifOperStatus = “down” AND ports.ifOperStatus_prev = “up” so if a port goes down it will be notified.
After new poll of device, the alert is in “Recent event” but it’s not visible in the alert list before a lot of minutes (and the port is still down).
Look at this image
First port down is notified after 10 minutes, the second port down (15:40) is not yet notified (30 minutes after)
Check you system time on the server that is hosting LibreNMS and set your timezone inside of php.ini
Also, alert rules can have a delay set in them, check that.
I’ve already check but it does not seem the problem.
I’ve found an error in configuration of alert template html. If i use the defaul template, mail are sent correctly.
Is it correct that a wrong template does not send anything instead of sending a wrong email?
Thanks a lot
Yes, if you have error in the alert templates it will cause the alert transport to stop until you correct the error in the template.
