Assorted Linux RedHat 7.x MRTG stand-alone configurations for graphing system activity incl network traffic without using SNMP

Assorted Linux RedHat 7.x MRTG stand-alone configurations for graphing system activity incl network traffic without using SNMP

I spent a day looking for a simple way to MRTG graph my local server
bandwidth, and found nothing, so I learned the config, whipped up the
answer, and thought I'd save you all from reinventing my same wheel.

This config has sections to graph ethernet traffic, system memory and
swap space usage, temperature, CPU Utilisation, disk IO, swap and
paging activity, and disk space. It should work on any RedHat 7+
system, and probably on 6.x too, and possibly on other unicies.

Use as many or as few as you wish.

(here's the stuff below in plain text:)
