barnacles-influxdb2
barnacles-influxdb2 writes ambient IoT timeseries data to InfluxDB v2.
barnacles-influxdb2 ingests a real-time stream of dynamb objects from barnacles which it writes to a given InfluxDB v2 instance. It couples seamlessly with reelyActive's Pareto Anywhere open source IoT middleware.
barnacles-influxdb2 is a lightweight Node.js package that can run on resource-constrained edge devices as well as on powerful cloud servers and anything in between.
Pareto Anywhere integration
A common application of barnacles-influxdb2 is to write IoT data from pareto-anywhere to an InfluxDB v2 timeseries database. Simply follow our Create a Pareto Anywhere startup script tutorial using the script below:
#!/usr/bin/env node
const ParetoAnywhere = require('../lib/paretoanywhere.js');
// Edit the options to specify the InfluxDB v2 instance
const BARNACLES_INFLUXDB2_OPTIONS = {};
// ----- Exit gracefully if the optional dependency is not found -----
let BarnaclesInfluxDB2;
try {
BarnaclesInfluxDB2 = require('barnacles-influxdb2');
}
catch(err) {
console.log('This script requires barnacles-influxdb2. Install with:');
console.log('\r\n "npm install barnacles-influxdb2"\r\n');
return console.log('and then run this script again.');
}
// -------------------------------------------------------------------
let pa = new ParetoAnywhere();
pa.barnacles.addInterface(BarnaclesInfluxDB2, BARNACLES_INFLUXDB2_OPTIONS);
