Amazon provides built-in monitoring functionality through CloudWatch and X-Ray, which enable users to query metrics, logs, and traces for their AWS Lambda functions. CloudWatch collects logs, metrics, and events from Lambda and other AWS services, while X-Ray allows users to trace requests as they invoke Lambda functions, enabling the pinpointing of bottlenecks in application workflows. The AWS Command Line Interface (CLI) can be used to pull metric data, and users can configure CLI settings for their account. CloudWatch divides metrics by namespace and dimension, allowing users to filter their metrics, while logs can be analyzed using query syntax to gain deeper insights into function activity. Alarms can be created in CloudWatch to notify users of issues such as Lambda errors and overprovisioned functions, and X-Ray enables the tracing of requests to identify performance bottlenecks. The AWS CLI provides access to Lambda functions' information, including logs and metrics, while Amazon's native tooling allows for monitoring platforms like Datadog to provide visibility into all components of an application in one place.
