Monitoring, debugging, and troubleshooting Lambda Event Functions

Amazon Lambda integrates with other Amazon Web Services services to help you monitor and troubleshoot your Lambda Event Functions. Lambda automatically monitors Event 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 Web Services services to troubleshoot your Lambda Event Functions. This section describes how to use these Amazon Web Services services to monitor, trace, debug, and troubleshoot your Lambda Event Functions and applications. For details about Event Function logging and errors in each runtime, see individual runtime sections. Topics include application monitoring, Application Signals, and logging Lambda API calls with CloudTrail.
