This page is limited to documentation for ingesting AWS Lambda metrics from Amazon CloudWatch. See the Datadog Serverless documentation for collecting telemetry directly from your Lambda functions in real time.

Overview

AWS Lambda is a compute service that runs code in response to events and automatically manages the compute resources required by that code.

Enable this integration to begin collecting CloudWatch metrics. This page also describes how to set up custom metrics, logging, and tracing for your Lambda functions.

Setup

Installation

If you haven’t already, set up the Amazon Web Services integration first.

Metric collection

AWS Lambda metrics

  1. In the AWS integration page, ensure that Lambda is enabled under the Metric Collection tab.

  2. Add the following permissions to your Datadog IAM policy to collect AWS Lambda metrics. For more information, see the Lambda policies on the AWS website.

    AWS PermissionDescription
    lambda:List*List Lambda functions, metadata, and tags.
    tag:GetResourcesGet custom tags applied to Lambda functions.
    cloudtrail:LookupEventsUse CloudTrail History to detect changes to lambda functions
  3. Install the Datadog - AWS Lambda integration.

Once this is completed, view all of your Lambda Functions in the Datadog Serverless view. This page brings together metrics, traces, and logs from your AWS Lambda functions running serverless applications into one view. Detailed documentation on this feature can be found in the Datadog Serverless documentation.

Data Collected

When using AWS Lambda extensions, the duration metric reported by AWS includes the post_runtime_extensions_duration consumed by Lambda extensions performing activities after the function response is returned. To monitor the actual performance of the function, use duration - post_runtime_extensions_duration or the Datadog enhanced metric aws.lambda.enhanced.runtime_duration.

Each of the metrics retrieved from AWS is assigned the same tags that appear in the AWS console, including but not limited to function name, security-groups, and more.

Events

The AWS Lambda integration collects Lambda deployment events from AWS CloudTrail if Datadog serverless deployment tracking is enabled.

Service Checks

The AWS Lambda integration does not include any service checks.

Lambda@Edge

Datadog automatically adds tags at_edge, edge_master_name, and edge_master_arn tags on your Lambda metrics to get an aggregated view of your Lambda function metrics and logs as they run in Edge locations.

Distributed tracing is not supported for Lambda@Edge functions.
