OpenCensus Agent Exporter for Node.js

OpenCensus Agent Exporter allows the user to send collected traces with OpenCensus Node.js to the OpenCensus Agent or Collector.

The library is in alpha stage and the API is subject to change.

Installation

Install OpenCensus Agent Exporter with:

npm install @opencensus/nodejs
npm install @opencensus/exporter-ocagent

Usage

Instance the exporter on your application. For javascript:

const tracing = require('@opencensus/nodejs');
const ocagent = require('@opencensus/exporter-ocagent');

const exporter = new ocagent.OCAgentExporter({

Similarly for Typescript:

import * as tracing from '@opencensus/nodejs';
import { OCAgentExporter } from '@opencensus/exporter-ocagent';
