Observability Guide

2. OpenTelemetry Integration​

FlowForge has native support for OpenTelemetry (OTel). When enabled, your workflows contribute to distributed traces.

Configuration (Spring Boot)​

flowforge:
  tracing:
    opentelemetry:
      enabled: true

What gets captured?​

  1. Workflow Span: A parent span representing the total execution time.
  2. Task Spans: Child spans for each task.
  3. Dependency Links: When a task depends on another, FlowForge adds a Span Link. This allows visualization tools (like Jaeger or Honeycomb) to reconstruct the DAG accurately, even with parallel branches.

Span Attributes​

Each span is enriched with library-specific attributes:

  • flowforge.workflow.id
  • flowforge.task.id
  • flowforge.execution.id
  • flowforge.task.input.type
  • flowforge.task.output.type
  • flowforge.task.status (SUCCESS, ERROR, SKIPPED)
