Server Only

PSA: This package is for monitoring Node.js server applications with Instana. If you want to monitor JavaScript applications running in a browser, check out our docs on website monitoring.

Installation And Usage

The installation of the Instana Node.js collector is a simple two step process. First, install the @instana/collector package in your application via:

npm install --save @instana/collector

Now that the collector is installed, it needs to be activated from within the application. Do this by requiring and initializing it as the first statement in your application. Please take care that this is the first statement as the collector will otherwise not be able to access certain information.

require('@instana/collector')();

// All other require statements must be done after the collector is initialized.
// Note the () after the require statement of the collector which initializes it.

// const express = require('express');

For more in-depth information, refer to the installation page.

CPU Profiling, Garbage Collection And Event Loop Information

The Node.js collector uses Native addons for some metrics. Check out the native addons documentation for details.

API

In most cases it is enough to require and initialize @instana/collector and let it do its work. However, there is an API for more advanced use cases.
