AWS

A company has a mobile application that makes HTTP API calls to an Application Load Balancer (ALB). The ALB routes requests to an AWS Lambda function. Many different versions of the application are in use at any given time, including a subset of versions that are in testing by a subset of users. The version of the application is defined in the user-agent header that is sent with all API requests to the API. After a recent series of changes to the API, the company has observed issues with the operation of the application. The company needs to take action to gather required metrics from the response by the Lambda function code. Which additional set of actions should the DevOps engineer take to gather the metrics?. Modify the Lambda function code to write the operation name, response code, and version number as a CloudWatch Logs log line to an Amazon CloudWatch Logs log group. Configure a CloudWatch Logs metric filter that increments a metric for each API operation name. Specify response code and application version as dimensions for the metric. Modify the Lambda function code to write the operation name, response code, and version number as a log line to an Amazon CloudWatch Logs log group. Configure a CloudWatch Logs Insights query to populate CloudWatch metrics from the log lines. Specify response code and application version as dimensions for the metric. Configure ALB access logs to write to an Amazon CloudWatch Logs log group. Modify the Lambda function code to respond to the ALB with the API operation name, response code, and version number as response metadata. Configure a CloudWatch Logs metric filter that increments a metric for each API operation name. Specify response code and application version as dimensions for the metric. Configure AWS X-Ray integration on the Lambda function. Modify the function code to create an X-Ray subsegment with the API operation name, response code, and version number. Configure X-Ray insights to extract an aggregated metric for each API operation name and to publish the metric to Amazon CloudWatch. Specify response code and application version as dimensions for the metric.
