Monitoring and troubleshooting Lambda functions
Amazon Lambda integrates with other Amazon services to help you monitor and troubleshoot your Lambda functions. Lambda automatically monitors Lambda functions on your behalf and reports metrics through Amazon CloudWatch. To help you monitor your code when it runs, Lambda automatically tracks the number of requests, the invocation duration per request, and the number of requests that result in an error.
You can use other Amazon services to troubleshoot your Lambda functions. This section describes how to use these Amazon services to monitor, trace, debug, and troubleshoot your Lambda functions and applications. For details about function logging and errors in each runtime, see individual runtime sections.
