4.15. Integration with CloudWatch Logs

Starburst’s CloudFormation template automatically integrates with CloudWatch Logs. Logs from Presto nodes will be uploaded to log streams in /starburstdata/presto/STACK_NAME log group. Additionally, log files are still stored and rotated on nodes themselves. Log stream names are of format STREAM-ROLE-INSTANCEID where:

  • ROLE is either coordinator or worker
  • INSTANCEID is an instance ID designated by AWS

STREAM can be one of:

  • presto stream contains Presto server logs
  • autoconfiguration stream contains Starburst autoconfiguration script logs
  • security stream contains query and user information for queries that were issued to coordinator (see Security Audit)
  • graceful-scaledown stream contains Starburst graceful scaledown handling script logs (there is a separate stream for each worker instance)
  • ha-heartbeat stream contains Starburst HA heartbeat script logs (there is a separate stream for each worker instance)
