Influx Express Middleware

This repository contains express middleware for logging request and response metrics to InfluxDB.

Usage

First add influx-express to your project:

$ cd /path/to/node/project
$ npm install --save influx-express

To enable the express logging middleware do the following:

var express = require('express')
var influxExpress = require('influx-express')
var app = express()

app.use(influxExpress())

app.get('/', function (req, res) {
  res.send('Hello World!')
})

app.listen(3000)

Changing the client defaults

var influxOpts = {
  protocol: "https",
  host: "fourbyfour-923ah8ar.influxcloud.net",
  port: 8086,
  database: "mydb",
  username: "myuser",
  password: "mypass",
  batchSize: 10,
  measurement: "requests"
}

app.use(influxExpress(influxOpts))
