Retrieves Apparent Wind and Atmospheric Pressure data from Influx database and writes it to MRTG style SVG graphs.
The apparent wind data is inserted into the database from an existing SignalK https://github.com/SignalK instance recieving data from the instruments on my boat.
Usage: /usr/local/bin/influxdbwindsvg [options]
InfluxDBWindSVG Version 3.20240121.1 Built on: Jan 21 2024 at 14:56:22
Options:
-? | --help Print this message
-v | --verbose level stdout verbosity level [1]
-W | --wind monitor environment.wind.speedApparent
-P | --pressure monitor environment.outside.pressure
-s | --svg name SVG output directory [""]
-x | --minmax graph Draw the minimum and maximum temperature and humidity status on SVG graphs. 1:daily, 2:weekly, 4:monthly, 8:yearly
-h | --host name InfluxDBHost []
-p | --port number InfluxDBPort [0]
-d | --database name InfluxDBDatabase []
-c | --cache name InfluxDBCacheDirectory [""]
If both wind and pressure are selected, a combined graph is produced as well as the individual graphs. It is most interesting at the weekly scale.
I started all of this trying to use https://www.influxdata.com/blog/getting-started-c-influxdb/ as a starting point.
It required getting https://github.com/offa/influxdb-cxx up and running, which required this as a prerequisite: https://github.com/libcpr/cpr
