Having issues where some devices are intermittently failing to poll down icmp. Image below shows typical example where device is polling without issues and then suddenly drops offline before later responding again.
Updated to latest version, confirmed validate returns successfully… a little lost!
Can you explain a bit more about your setup, where the device you are polling is in relation to the poller, how many pollers (i.e. is it a distributed install or all on one box?)
Is there any pattern to the devices and have you validated connectivity is working between the poller and the device when librenms is not polling.
