daald/munin-server repository overview

A docker container with minimal resource footprint. Capable for small servers like NAS or Raspberry Pie. Webserver and cron are replaced by small executables. FastCGI is not used. Instead, we use CGI which doesn't need a pooled processes. Sure, this is not fast. But it's still faster than every prometheus instance on the same machine. Munin itself saves its data in RRD files which themselves have a very low footprint. Sure, the grephs are not as fancy as with other tools, but most people need them only very rarely anyway.
