A small application that generates different kinds of logs to the standard output for testing of log aggregation systems. It will print a predefined set of log messages at different levels, with a formatting of your choice.
The simplest way to run it is to use the published Docker image dolittle/logfeeder, for example:
$ docker run dolittle/logfeeder

This program does not really have a purpose, I will just sit here and print log messages forever. If you were expecting something else, you should probably run another program. But I can't really help you figure out which one. If you find out, please let me know 👍
