NodeJS

Library

Overview

The Node.js integration allows you to collect and monitor your Node.js application logs, traces, and custom metrics.

Setup

Metric collection

The Node.js integration enables you to monitor a custom metric by instrumenting a few lines of code. For instance, you can have a metric that returns the number of page views or the time of any function call.

Instrumentation can be implemented using hot-shots, an open source DogStatsD client for Node.js.

For additional information about the Node.js integration, refer to this guide on submitting metrics.

1. Install hot-shots with npm:

   npm install hot-shots

2. Start instrumenting your code:

   var StatsD = require('hot-shots');
   var dogstatsd = new StatsD();
   
   // Increment a counter.
   dogstatsd.increment('page.views')
   

Trace collection

See the dedicated documentation for instrumenting your Node.js application for sending traces to Datadog.

Log collection

Available for Agent v6.0+

See the dedicated documentation to set up Node.js log collection for forwarding your logs to Datadog.
