OpenCensus Object Exporter

OpenCensus Object Trace Exporter allows the user to collect and programmatically access traces with OpenCensus Node.js. This module is useful for when you need to access collected spans programmatically, for example for testing purposes.

Installation

Install OpenCensus Object Trace Exporter with:

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

Usage

For javascript:

const tracing = require('@opencensus/nodejs');
const { ObjectTraceExporter } = require('@opencensus/exporter-object');

const exporter = new ObjectTraceExporter();

Similarly for Typescript:

import * as tracing from '@opencensus/nodejs';
import { ObjectTraceExporter } from '@opencensus/exporter-object';
const exporter = new ObjectTraceExporter();

Now, register the exporter and start tracing.

tracing.start({'exporter': exporter});

or

tracing.registerExporter(exporter).start();

Viewing your traces

exporter.startedSpans.forEach((span: Span)) => {}
exporter.endedSpans.forEach((span: Span)) => {}
exporter.publishedSpans.forEach((span: Span)) => {}

Reset exporter

Empties startedSpans, endedSpans and publishedSpans span stores.

exporter.reset();
