A Serverless Framework Plugin allowing to enable Lambda Insights.
A Serverless Framework Plugin allowing to enable Lambda Insights
Enables AWS Lambda Insights (https://aws.amazon.com/blogs/mt/introducing-cloudwatch-lambda-insights/) for the entire Serverless stack functions or individual functions.
CloudWatch Lambda Insights is a monitoring and troubleshooting solution for serverless applications running on AWS Lambda. The solution collects, aggregates, and summarizes system-level metrics including CPU time, memory, disk, and network. It also collects, aggregates, and summarizes diagnostic information such as cold starts and Lambda worker shutdowns to help you isolate issues with your Lambda functions and resolve them quickly.
This Plugin requires a Serverless Framework version of >= 2.0.0.
npm install --save-dev serverless-plugin-lambda-insights
add Plugin to your
serverless.yml in the plugins section.
provider: name: aws plugins: - serverless-plugin-lambda-insights functions: hello: handler: handler.hello lambdaInsights: true
The plugin will enable Lambda Insights by adding a Lambda Layer (see Layer Details and Versions) and adding necessary permissions using the
arn:aws:iam::aws:policy/CloudWatchLambdaInsightsExecutionRolePolicy as a AWS IAM Managed Policy.
You can check in your AWS Console:
go to AWS Lambda -> select your Lambda function -> Configuration tab -> Monitoring tools ->
"CloudWatch Lambda Insights".
lambdaInsights validated to
true for a function,
the checkbox will be checked.

This will deploy a hello-world Lambda function with Lambda Insights enabled.
