Monitoring and Troubleshooting Lambda Applications
AWS Lambda automatically monitors Lambda functions on your behalf, reporting metrics through Amazon CloudWatch. To help you monitor your code as it executes, Lambda automatically tracks the number of requests, the execution duration per request, and the number of requests resulting in an error and publishes the associated CloudWatch metrics. You can leverage these metrics to set CloudWatch custom alarms. For more information about CloudWatch, see the Amazon CloudWatch User Guide.
You can view request rates and error rates for each of your Lambda functions by using the AWS Lambda console, the CloudWatch console, and other AWS resources. The following topics describe Lambda CloudWatch metrics and how to access them.
You can insert logging statements into your code to help you validate that your code
is working as expected.
Lambda automatically integrates with Amazon CloudWatch Logs and pushes all logs from
your code to a CloudWatch Logs group associated with a
Lambda function (/aws/lambda/<function name>). To learn more about log groups and
accessing them through the CloudWatch console, see the Monitoring
System, Application, and Custom Log Files in the Amazon CloudWatch User Guide. For information
about how to access CloudWatch log entries, see Accessing Amazon CloudWatch Logs for AWS Lambda.
