I already wasted days to look for a very minimalist (cpu/ram/ping/ssh/disks) monitoring tools that discover hosts by itself instead of installing a client application on each host. (I can accept giving a temporary account with ssh-key) but not any local binaries installation. (because the solution have to be movable from a LAN to another or another or another for few days only)
I did not find any? Do you know such product?
Currently I use a boring MySQL/Nagios couple of docker containers but this solution is very bad because it doesn't do discovering (so I can only monitor hosts that client knows/remember existence) & I lose half a day to one day to setup it specially for the concerned LAN...
Do you know a solution corresponding to my needs?
