After a series of recent changes t o the API, the company has observed issues with the applicatio n. The company needs to gather a metric for each AP I operation by response code for each version of the application that is in use. A DevOps engineer has m odified the Lambda function to extract the API operation na me, version information from the user-agent header and response code. Which additional set of actions shou ld the DevOps engineer take to gather the required metrics?
