Sounds nice, but why does it need to run on each backend?
Actually, it doesn't. Just on systems where you want to monitor something. It's a more generic solution that can be used for more than just MythTV. The code will eventually allow people to write simple plug-ins to monitor whatever their hearts desire.

Why would you need new database tables. I haven't looked into the job
status, but all the other things are easily retrieved through the
backend protocol. The guide data status has been in there since Isaac
accepted my patch adding it to the backend server.
All the new tables except one, hold configuration data for the various things you want to monitor. The other table holds the results of all the analysis.

Hmm, same here. Actually I use bicolor LEDs for each of the 8 tuners
(green=tuner available but not recording, red=tuner recording, off=no
tuner or tuner error), and have a system status light that comes on if
guide data < 7 days or will flash on low disk space or guide data < 3
days. I almost forgot, there is also a buzzer inside that will start
beeping if communications with the backend are lost. The tuner LEDs do
support tuners on slave backends.
Your solution looks beautiful. But seems beyond my target budget (<$10) and diffently beyond my soldering skills. The parallel port, resistor, LED solution is supper easy and cheap.
Check out the link in my sig for pictures of the LEDs and the source
code for the monitor program which runs on the frontend (and doesn't
require any database or backend changes).
This is a really nice looking box! I wish I weren't cheap :)
Of course, the OP was asking for something simple... oops :-)
