Execution events

Each workflow execution produces a detailed log of execution events. Execution events log is disabled by default to protect PII data
and can be turned on by running the instance with profile enable-execution-log turned on.
These include life-cycle events, execution requests, responses, errors, executed commands, results etc.

The execution events are stored in execution_events Kafka topic. They are timestamped and correlated by execution UUID.

When aggregated, execution events can be used for troubleshooting. They can be processed for real-time metrics and analytics purposes.

Execution life-cycle

• Started Event
  produced when execution starts

• Expired Event
  produced when execution expires

• Terminated Event
  produced when execution terminates

Execution requests

• Execute Request

• when a command is executed (CommandEvent)
  • route (RouteEvent)
  • exchange (ExchangeEvent)
  • go back (BackEvent)
• command result is provided
  • route result (RouteResultEvent)
  • exchange result (ExchangeResultEvent)
  • attribute set (AttributeSetterEvent)
• function execution
  • executed (FunctionEvent)
  • result is provided (FunctionResultEvent)
• errors
  • validation error (ValidationErrorEvent)
  • execution error (ErrorEvent)
