I’ve been playing around with LibreNMS but I noticed that it took some time for LibreNMS to detect a network failure (interface down, cable disconnected, etc.).
For example, when I disconnect a cable from the router, it takes usually more than 5 minutes for LibreNMS to detect that the route is down and to turn everything related to red.
Is this normal, or is this a hardware problem, or perhaps something else?
Thanks in advance.
