What should a SysOps administrator do to meet this requirement?
Perform a CloudWatch Logs Insights query that uses the stats command and count function.
Perform a CloudWatch Logs search that uses the groupby keyword and count function.
Perform an Amazon Athena query that uses the SELECT and GROUP BY keywords.
Perform an Amazon RDS query that uses the SELECT and GROUP BY keywords.
Explanations:
Using CloudWatch Logs Insights, the administrator can run a query that employs thestatscommand with thecountfunction to aggregate error counts across multiple log groups. This method is optimized for log data analysis and allows for efficient grouping by error type.
CloudWatch Logs does not support agroupbykeyword in its search functionality. The search capability is limited and does not provide the advanced aggregation features necessary for counting and grouping error types across multiple log groups.
While Amazon Athena can query log data stored in Amazon S3, it is not applicable in this scenario as it specifically mentions querying across CloudWatch Logs log groups. Athena would require exporting logs to S3 first, which adds unnecessary complexity for this task.
Amazon RDS is a relational database service and is not suited for querying CloudWatch Logs. This option is irrelevant to the task, as it does not interact with log data and cannot group or count application errors from the specified log groups.
I classify that the answer is:
Perform a CloudWatch Logs Insights query that uses the stats command and count function.
