The log group is /aws/vpc/flowlogs and default field names are used. Which query meets the requirement?

  • fields srcAddr | stats count(*) as connections by srcAddr | sort connections desc | limit 1

  • fields srcAddr, bytes | filter @timestamp >= ago(1h) | sort bytes desc | limit 1

  • fields srcAddr, bytes | filter @timestamp >= ago(1h) | stats max(bytes) as maxBytes by srcAddr | sort maxBytes desc | limit 1

  • fields srcAddr, bytes | filter @timestamp >= ago(1h) | stats sum(bytes) as totalBytes by srcAddr | sort totalBytes desc | limit 1
