Signal K Node server plugin to write all simple numeric Signal K values to InfluxDB, a time series database.
Once the data is in InfluxDb you can use for example Grafana to draw pretty graphs of your data.
The plugin assumes that the database you specify exists. You can create one with
curl -X POST http://localhost:8086/query?q=CREATE+DATABASE+boatdata
The plugin writes only self data. It converts Signal K paths to InfluxDb measurement keys in CamelCase format, eg. navigationPosition.
Adding support for non-self data would be pretty easy by adding context as InfluxDB tags.
If you want to try this out I suggest you try InfluxCloud (have not tried yet myself) or run InfluxDb locally with Docker by using ready made Dockerfiles.
Compatible with InfluxDB 1.x.
