I am facing an issue in LibreNMS while monitoring multiple devices, and I would like your suggestions.
For example, one of my devices (Mikrotik CRS-504) has been added and monitored for over a year. Recently, I noticed that one of its SFP interfaces/ports was automatically deleted during the 15-minute discovery process. After that, the port is no longer visible in LibreNMS.
The same behavior is occurring on multiple devices. We also tried replacing the SFP module and swapping the interface, but the problem continues—the new interface also gets deleted after discovery.
I would like to understand what could be causing this issue so that we can fix it. Has anyone else faced a similar problem? Any guidance or resolution would be highly appreciated.
Thanks in advance.
