Profiling and tracing for AWS Lambda

IOpipe Profiler Plugin

This is a profiler and tracing library for use with IOpipe and AWS Lambda.

Installation:

With yarn (recommended) in project directory:

yarn add @iopipe/profiler

With npm in project directory:

npm install @iopipe/profiler

Then include the plugin with IOpipe in your serverless function:

const iopipeLib = require('iopipe');
const profiler = require('@iopipe/profiler');

const iopipe = iopipeLib({
  plugins: [profiler({ enabled: true })]
});

exports.handler = iopipe((event, context) => {
  context.succeed('Wow!');
});

Config

enabled (bool: optional = false)

By default, this plugin will not run the profiler. You must enable profiling on your function either by setting this variable, or setting IOPIPE_ENABLE_PROFILER=true in your environment. The environment variable setting (either true or unset) takes precedence over plugin config.

recSamples (bool: optional = true)

Record samples, defaults to true.

sampleRate (number: optional = 1000)

Change the sampling interval, in microseconds. Defaults to 1000us.

debug (bool: optional = false)

Show debugging logs.

Environment Variables

To enable profiling via environment variable, set IOPIPE_ENABLE_PROFILER to true in your environment.
