Datadog Serverless Plugin

This serverless framework plugin automatically instruments your Python and NodeJS Lambda functions with Datadog's native Lambda Layers. You can use this function to collect traces, and custom metrics.

Installation

You can install the plugin with one of the following commands. Keep in mind, you will need to bundle this package with your function manually.

yarn add --dev serverless-plugin-datadog         # Yarn users
npm install --save-dev serverless-plugin-datadog # NPM users

Then in your serverless.yml add the following:

plugins:
  - serverless-plugin-datadog

How it works

This plugin attaches the Datadog Lambda Layers for Node.js and Python to your functions. At deploy time, it generates new handler functions that wrap your existing functions and initializes the Lambda Layers.

Configurations

You can configure the library by add the following section to your serverless.yml:

Datadog Log Forwarder

Default

custom:
  datadog:
    # Whether to add the Lambda Layers, or expect the user to bring their own
    addLayers: true
    # Datadog API Key, only necessary when using metrics without log forwarding
    apiKey: ""
    # Whether the log forwarder integration is enabled by default
    flushMetricsToLogs: false

All Options

custom:
  datadog:
    # Add one of the following variables to override it's default

    # Whether to add the Lambda Layers, or expect the user to bring their own
    addLayers: true

    # Datadog API Key, only necessary when using metrics without log forwarding
    apiKey: ""

    # Datadog API Key encrypted using KMS, only necessary when using metrics without log forwarding
    apiKMSKey: ""

    # Which Site to send to, (should be datadoghq.com or datadoghq.eu)
    site: datadoghq.com

    # The log level, (set to DEBUG for extended logging)
    logLevel: "info"

    # Whether the log forwarder integration is enabled by default
    flushMetricsToLogs: false

FAQ

What if I want to provide my own version of `datadog-lambda-layer-js` or `datadog-lambda-layer-python`?

You can use your own version of those libraries by setting 'addLayers' to false in the datadog configuration block. Just make sure to bundle those libaries with your Lambda functions.
