▲ 7 ▼ A minimalistic 12 factor log router written in Go

The 12 factor rule for logging says that an app "should not attempt to write to or manage logfiles. Instead, each running process writes its event stream, unbuffered, to stdout." The execution environment should take care of capturing the logs and perform further processing with it. Funnel is meant to be a replacement for your app's "logger + logrotate" pipeline. Think of it as a fluentd/logstash replacement(with minimal features!) but having only stdin as an input. All you need to do is just print to stdout and pipe it to funnel. And let it take care of the rest.
