I have been experiencing an issue with my instance of LibreNMS version 26.1.1 where a port will go down but it doesn’t alert it as being down.
This issue happens at random and I have been unable to diagnose what is causing it. An example of this is where we had a link between two switches go down and only one side of the link alerted about it. I believe that LibreNMS had picked up that the port had gone down in the event log but just never sent an alert notification.
If someone could shine some light on this or point me in the right direction to figuring out what is going on, it would be appreciated.
