Flogger for Node-Red

This Node-Red module makes logging much easier and more granulated than the debug window of Node-Red. Please install it and see the help in the info-pane of Node-Red.

With flogger you can log to multiple logfiles from everywhere in your flows. It's easy to keep logging your flows without clogging up the Node-Red debug pane.

You can define different output formats like plain textfile or JSON format like NLOG.

Logrotation with/without compression can be enabled.

Here is an example of how to use the logger:

A log config - most people probably only need one:

A log node:

Example output ~/logs/logfile1:
