Accessing the API logs and metrics

API logs are published to Amazon CloudWatch with a retention of 30 days. To retrieve the LogGroup name associated with an API deployment, run the following command:

$ REGION=<region>
$ API_STACK_NAME=<stack-name>
$ aws cloudformation describe-stacks --region ${REGION} --stack-name ${API_STACK_NAME} --query "Stacks[0].Outputs[?OutputKey=='ParallelClusterLambdaLogGroup'].OutputValue" --output text

Lambda metrics, logs and AWS X-Ray trace logs can be also accessed through the Lambda console. To retrieve the ARN of the Lambda function associated with an API deployment run the following command:

$ REGION=<region>
$ API_STACK_NAME=<stack-name>
$ aws cloudformation describe-stacks --region ${REGION} --stack-name ${API_STACK_NAME} --query "Stacks[0].Outputs[?OutputKey=='ParallelClusterLambdaArn'].OutputValue" --output text
