I have a Python script which is designed to run continuously, outputting status messages to the console and to a logfile via logger instances.
This is fine as such.
What I would really love, however, is to condense the most important details into an always-visible "dashboard" at the bottom of the console. Something like this:
Timestamp - Logger info - Minor status update 1
Timestamp - Logger info - Status has changed
Timestamp - Logger info - Status has changed again
Timestamp - Logger info - Successfully opened file
Timestamp - Logger info - Successfully closed file
Timestamp - Logger info - Never gonna give you up
Timestamp - Logger info - Never gonna let you down...
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
+ Statistics: Critical errors so far: 0. Processing: 12 units/second. +
+ Current running time: 44839 seconds. Foos barred: 3. Bars fooed: 11. +
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Is there a good way to do this? I haven't been able to find any...
I know it's doable, tools like wget do it all the time:

I am specifically NOT looking for a web based tool or a graphical interface like most people who seem to be asking about "dashboards"... just a command line interface oriented way to extend what I'm already doing a little.
One way to do this would be with ANSI control characters -- but I am worried that would throw off the logger output (which I want to keep!).
The best solution I've found so far is tqdm which is a pure progress bar... unfortunately I am not trying to "measure progress," just display a few vital statistics persistently at the bottom of the display. And, as sexy as it is, I'm not sure if it will play well with logger!
