======= poor man's monitoring: GKrellM =======
* https://en.wikipedia.org/wiki/GKrellM – GKrellM
* a GKrellMd (daemon) runs wherever – on a production server, an embedded device
* the respective GKrellM front end communicates with the daemon
* there is also an implementation of the GKrellM front end available for Windows

======= taking "poor man's monitoring" a little further =======
* you may have quite a few servers to survey, so you also got quite a few front ends
* you may find it a nuisance to start the front ends "again and again"
* so you can just as well run the front ends within a VNC server, so the front ends can just run for the time being …
* of course the VNC server may run itself within a VM
* and you connect to the VNC server using a VNC viewer – on whatever platform (within your LAN)
