iopipe-plugin-trace

IOpipe Trace Plugin

Create marks and measures for arbitrary units of time. Measure latency of database calls, third party requests, or code blocks and visualize them in IOpipe!

Requirements

• Node >= 4.3.2
• NPM >= 2.14.12
• IOpipe >= 0.8.0

Install

With yarn (recommended) in project directory:

yarn add iopipe-plugin-trace

With npm in project directory:

npm install iopipe-plugin-trace

Then include the plugin with IOpipe in your serverless function:

const iopipeLib = require('iopipe');
const tracePlugin = require('iopipe-plugin-trace');

const iopipe = iopipeLib({
  plugins: [tracePlugin()]
});

// wrap your lambda handler
exports.handler = iopipe((event, context) => {
  context.iopipe.mark.start('database');
  // after database call is finished
  context.iopipe.mark.end('database');

  context.iopipe.mark.start('analytics');
  // after analytics call is finished
  context.iopipe.mark.end('analytics');
  context.succeed('Wow!');
});

Methods

// create the start mark
// the string argument is a name you are assigning the particular trace
context.iopipe.mark.start('db');

// create the end mark
// pass the name of the trace that you want to end
context.iopipe.mark.end('db');

// create an custom measurement between start:init and end:db
context.iopipe.measure('custom', 'init', 'db');

Config

autoMeasure (bool: optional = true)

By default, the plugin will create auto-measurements for marks with matching mark.start and mark.end. These measurements will be displayed in the IOpipe Dashboard. If you'd like to turn this off, set autoMeasure: false.

const iopipe = iopipeLib({
  plugins: [tracePlugin({
    autoMeasure: false
  })]
});
