§Debug Service
Provides a diagnostic stage that passes data through unchanged while emitting metrics to Prometheus for real-time monitoring and debugging.
§Purpose
Debug stages are useful for:
- Detecting Data Corruption: Calculate checksums at intermediate points
- Performance Analysis: Measure throughput between stages
- Pipeline Debugging: Monitor data flow through complex pipelines
- Production Monitoring: Real-time visibility into processing
§Metrics Exposed
Each DebugStage emits to Prometheus:
debug_stage_checksum{label, chunk_id}- SHA256 of chunk datadebug_stage_bytes{label, chunk_id}- Bytes processed per chunkdebug_stage_chunks_total{label}- Total chunks processed
§Label Uniqueness
Each DebugStage is automatically assigned a ULID label during creation, ensuring no metric name conflicts when multiple debug stages exist in a pipeline.
§Usage
# Create pipeline with debug stages at key points
pipeline create --name test --stages base64,debug,brotli,debug,encryption
# Monitor via Prometheus
curl http://localhost:9091/metrics | grep debug_stageStructs§
