I would be worried about one of the processes having a database password or something like that as a parameter...

Neat thanks!

You can generate HTML (and from that png or whatever) with http://www.pixelbeat.org/scripts/ansi2html.sh like

    $ COLUMNS=80 timeout 1 htop > t.ansi
    $ ansi2html.sh --bg=dark  t.html

I've requested a -b, --batch option for htop, to simplify this mode of operation. https://github.com/hishamhm/htop/issues/282 Then you could just:

    $ COLUMNS=80 htop -b | ansi2html.sh ...

Even though some software does replace the password, it would be better not to use passwords like that at all anyway. Just to be sure.

Good point. I think we should be caeful what we do, while administrating the server.

Maybe we could build some automatism which stops the screenshot service while an ssh session is established.

Would be more interesting if the background is live, like updating itself every second or half a second.

I wonder how https://github.com/ansilove/AnsiLove-C would fare for generating the PNG compared to the current solution.

Nice idea although a bit dangerous! I wonder if it would be better to use as background the output of a program like gotty, which streams a terminal's output as a web page.
