Yes, I know how that sounds. But testing in my case is installing
slim Debian, apache on top of it and running some light web application
for a few hours. Nothing intensive. Just to have fresh machine with
nothing on it. But if running it sounds too bad I could just run it
somewhere else. Thanks for your advice, Martin!
On the other hand, monitoring has to be here, no place else to put it.
