Which solution will meet these requirements with the LEAST effort?
Use AWS Glue and write custom scripts to query CloudTrail logs for the errors.
Use AWS Batch and write custom scripts to query CloudTrail logs for the errors.
Search CloudTrail logs with Amazon Athena queries to identify the errors.
Search CloudTrail logs with Amazon QuickSight. Create a dashboard to identify the errors.
Explanations:
Using AWS Glue and custom scripts is complex and requires more setup and maintenance than necessary.
AWS Batch with custom scripts also involves a high degree of customization and is more effort-intensive.
Amazon Athena allows direct querying of CloudTrail logs with SQL-like syntax, offering simplicity and efficiency.
Amazon QuickSight is a visualization tool, not optimized for log searching and querying for specific errors.
I surmise that the answer is:
Search CloudTrail logs with Amazon Athena queries to identify the errors.
