signalk-data-logger

A Signal K Node server plugin for logging all Signal K deltas to flat files. The file rotation interval can be configured and the old files are compressed to save space.

Installation

Should be eventually available on the Signal K Appstore.

Configuration

You need to provide a directory for writing the log files. Make sure the Node server process has permissions to write to the defined directory!

Log rotation interval defines how often the destination file is changed. Old files are automatically compressed with Gzip. SK deltas are very repetitive, so the compressed files are only 3.5% of the original file size. If you prefer not to rotate the logs, define an interval of 0.
