Hostnames alternatively and intermittenly displaying in red

Help
1

Hello,

Observation while browsing All Devices page
Sometimes some hostnames are showing in red, but these devices are actually reachable via snmpwalk from LibreNMS server. At a later time, some other hostnames being reachable via snmpwalk display in red.

Q1: hostname displaying in red = polling to these devices in the last polling cycle was failed?

Q2: What could be the root causes of this kind of intermittent failures?

Any help would be much appreciated.

Thanks Kevin.
Found in Eventlog: ‘Device status changed to Down from icmp check’, fake alert though.

You will most likely need to tune something - go check the performance docs

Thanks laf. Looking into it. Fake alerts is a very helpful link that I started with, from fake alert towards performance.
