Which action will meet this requirement in the MOST operationally efficient manner?
Use Amazon Athena to query the Amazon CloudWatch logs that are associated with the Lambda function.
Use Amazon Athena to query the AWS CloudTrail logs that are associated with the Lambda function.
Use Amazon CloudWatch Logs Insights to query the associated Lambda function logs.
Use Amazon OpenSearch Service (Amazon Elasticsearch Service) to stream the Amazon CloudWatch logs for the Lambda function.
Explanations:
Athena can query CloudWatch logs, but it is not the most operationally efficient method for querying Lambda logs. CloudWatch Logs Insights is more optimized for this use case.
CloudTrail logs are useful for tracking API calls and user actions, not specifically for querying Lambda function logs, making this option unsuitable.
CloudWatch Logs Insights is specifically designed for querying logs in an efficient manner, including Lambda logs, and provides powerful query capabilities.
OpenSearch is more suitable for searching and visualizing logs, but it requires more setup and is less operationally efficient for simple log queries.
