<p style='margin-top:0;margin-bottom:10px;'>What is happening: Logger is set to trace so it passes everything, event is formatted, event is discarded by ThresholdFilter.</p>
<p style='margin-top:0;margin-bottom:10px;'>The idea for this configuration is to have several log files with different detalization. I think this is a valid usecase.</p>
