4.16. Integration with CloudWatch Logs#

Starburst’s CloudFormation template automatically integrates with CloudWatch Logs. Logs from Presto nodes are uploaded to log streams in a /starburstdata/presto/STACK_NAME log group. Additionally, log files are stored and rotated on nodes themselves. Log stream names us a 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 the Presto server logs
  • autoconfiguration stream contains auto-configuration script logs
  • security stream contains query and user information for queries issued to the coordinator (see Query Audit)
  • graceful-scaledown stream contains graceful scale down handling script logs (there is a separate stream for each worker instance)
  • ha-heartbeat stream contains HA heartbeat script logs (there is a separate stream for each worker instance)
