Few of my devices (Mikrotik’s) are faling for ICMP checks and being marked as “Device status changed to Down from icmp check”. This happening few time’s a day. Devices are not gonig down, up time is high, only fails for ICMP check by librenms.
Could You please help me resolve this issue?
Either your LibreNMS box is under too much load or your device is genuinely dropping icmp packets. When it happens, we show a new tab for the device which will have a traceroute output, see if that shows anything.
