Amazon 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.
If you haven’t already, set up the Amazon Web Services integration first.
In the AWS integration tile, ensure that Lambda is checked under metric collection.
Add the following permissions to your Datadog IAM policy to collect Amazon Lambda metrics. For more information on Lambda policies, review the documentation on the AWS website.
| AWS Permission | Description |
|---|---|
lambda:List* | List Lambda functions, metadata, and tags. |
tag:GetResources | Get custom tags applied to Lambda functions. |
cloudtrail:LookupEvents | Use CloudTrail History to detect changes to lambda functions |
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.

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.
Custom metrics are only tagged with function name.
The AWS Lambda integration does not include any events.
The AWS Lambda integration does not include any service checks.
Datadog generates real-time Lambda runtime metrics out-of-the-box for Node.js, Python, and Ruby runtimes. Refer to updated Serverless documentation to learn more.

Datadog supports distributed tracing for your AWS Lambda functions using either Datadog APM or AWS X-Ray. You can use either set of client libraries to generate traces, and Datadog APM will connect traces from applications running on hosts, containers, and serverless functions automatically. Refer to updated Serverless documentation to learn more.
The Datadog Node.js, Python, and Ruby tracing libraries support distributed tracing for AWS Lambda, with more runtimes coming soon. The easiest way to add tracing to your application is with the Datadog Lambda Library, which includes the Datadog tracing library as a dependency. Refer to updated Serverless documentation to learn more.
When applicable, Datadog merges AWS X-Ray traces with native Datadog APM traces. This means that your traces will show the complete picture of requests that cross infrastructure boundaries, whether it be AWS Lambda, containers, on-prem hosts, or managed services. Refer to updated Serverless documentation to learn more.
Any tag applied to your Lambda function automatically becomes a new dimension on which your can slice and dice your traces. Refer to updated Serverless documentation to learn more.
The following Lambda function integrations provide additional functionality for monitoring serverless applications. Refer to the corresponding Serverless documentation to learn more.
Install the Datadog Lambda Library to collect and send custom metrics. Refer to updated Serverless documentation to learn more.
With distribution metrics, you select the aggregation when graphing or querying it instead of specifying it at submission time. Refer to updated Serverless documentation to learn more.

In your function code, you must import the necessary methods from the Lambda Layer and add a wrapper around your function handler. Refer to updated Serverless documentation to learn more.
