Package Exports

epsagon

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (epsagon) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Epsagon Instrumentation for Node.js

This package provides an instrumentation to Node.js code running on functions for collection of distributed tracing and performance monitoring.

Installation

From your project directory:

npm install --save epsagon

Getting started

Simply use the wrapper to send traces from your code:

const epsagon = require('epsagon');
epsagon.init({
    token: 'my-secret-token',
    appName: 'my-app-name',
    metadataOnly: false, // Optional, send more trace data
});

function handler(event, context, callback) {
    callback(null, 'It worked!')
}

handler = epsagon.lambdaWrapper(handler)

Custom labels

You can add custom labels to your traces. Filters can later be used for filtering traces that contains specific labels:

function handler(event, context, callback) {
    epsagon.label('myCustomLabel', 'labelValue');
    callback(null, 'It worked!')
}
