Good Day
I am having some problems in the last month where I am monitoring the "ping" probe on my devices on a large Wireless Network. The Dude sometimes thinks they are unreachable, but If I do a ping from "local" I can reach it.
The ping from "server" and from "local" I have done from the server itself. I have also run a ping from Command Prompt and it works as well.
I have tried to do an sqlite3 "vacuum" of the database but this has not helped at all.
To temporarily resolve the problem I have to restart the dude service/server and reprobe all "down" devices.
Please see the screenshot below for my example of a site which is showing as "down" but is infact up
