I go for A. 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. After you have installed the Lambda Insights extension on a Lambda function that has been invoked, you can use the CloudWatch console to see your metrics. You can see a multi-function overview, or focus on a single function. https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/Lambda-Insights-view-metrics.html
