signalk-to-influxdb-v2-buffering

Plugin that saves data to an influxdbv2 database - buffers data without internet connection

The plugin is designed to do batch writes to a cloud hosted influxdb2.0 data base. The Plugin now uses the https://github.com/influxdata/influxdb-client-js library. If the conenction to the influxdb is down the batch of metrics should be buffered and re uploaded when the internet connection is re-established

Influx Measurement format

It is storing the metrics in the following format eg:

propulsion.port.transmission.oilPressure = 30.0
navigation.position.latitude = -19.26

The field is always 'value'

Paths Supported

Currently the pulgin is only supporting all paths that have a numrical value (also position and attitude).
