Gitter chat Node Version NPM Published Version dependencies Status devDependencies Status Apache License

The OpenCensus Prometheus Exporter allows the user to send collected stats with OpenCensus Node.js to Prometheus.

This package is still at an early stage of development, and is subject to change.

Installation

Install OpenCensus Prometheus Exporter with:

npm install @opencensus/core
npm install @opencensus/exporter-prometheus

Usage

Instance the exporter on your application.

For javascript:

const { Stats } = require('@opencensus/core');
const { PrometheusStatsExporter } = require('@opencensus/exporter-prometheus');

// Add your port and startServer to the Prometheus options
const exporter = new PrometheusStatsExporter({
  port: 9464,
  startServer: false
});

Now, register the exporter.

// Our Stats manager
const stats = new Stats();

// Pass the created exporter to Stats
stats.registerExporter(exporter);

// Run the server
exporter.startServer(function callback() {
  // Callback
});

Similarly for Typescript (Since the source is written in TypeScript):

import { PrometheusStatsExporter } from '@opencensus/exporter-prometheus';
import { Stats } from '@opencensus/core';

// Add your port and startServer to the Prometheus options
const options = {port: 9464, startServer: false};
const exporter = new PrometheusStatsExporter(options);

// Our Stats manager
const stats = new Stats();

// Pass the created exporter to Stats
stats.registerExporter(exporter);

Viewing your metrics:

With the above you should now be able to navigate to the Prometheus UI at: http://localhost:9464/metrics
