AWS Certified Data Engineer Associate DEA-C01 Practice Question

An AWS Glue ETL job writes driver logs to the log group /aws-glue/jobs/output in JSON format. Each log event contains the fields level, message, and jobRunId. You must use CloudWatch Logs Insights to quickly show a count of unique jobRunId values that logged the string "ERROR TimeoutException" during the last 24 hours, while minimizing query cost. Which query meets these requirements?

  • filter message like /ERROR TimeoutException/ | stats count(jobRunId)

  • fields message, jobRunId | filter message like /ERROR TimeoutException/ | stats count_distinct(jobRunId) as affectedRuns

  • fields @timestamp, jobRunId, message | filter message like /TimeoutException/ | stats count_distinct(message)

  • fields @timestamp, jobRunId, message | sort @timestamp desc | filter message like /ERROR TimeoutException/ | limit 1000 | stats count_distinct(jobRunId)
