logging module

[Werner F. Bruhin]

I am starting to use the logging module.

Simple log to file and/or console work very nicely.

Even managed to get TimedRotatingFileHandler to work.

The problem I am trying to solve.

1. I would like to have a "log viewer" a wxPython based app to be able
to look at a log generated by another script.

Did a little test for this.
- log_testing.py attached is generating the log entries
- log_viewerConsole.py is trying to attach to the same logger (would
convert/change this to a wxPython app)

The log_viewerConsole script only sees the logs it generates. Does this
script have to be started by the first one to get the same logger?

Any hints on how to solve my problem would be very appreciated.

Running in a separate process? That isn't possible. Okay, well, it
isn't possible without doing a fair amount of work on your own. You
would probably need to create a handler that writes everything to a
pipe or a socket, and then have your second application read from the
pipe/socket and display it. I don't think that feature exists right
now though.

Yes, it does, it's easy, and it's one of the examples included in the
logging documentation.
