# OpenTelemetry Collector Configuration
# This is a standalone service that receives traces from Dexto and forwards them to backends
# Flow: Dexto app → Collector (this config) → Jaeger/other backends

# ===== RECEIVERS =====
# How the collector RECEIVES telemetry data from Dexto
receivers:
  otlp:
    protocols:
      http:
        endpoint: "localhost:4318"  # Dexto sends traces here via OTLPHttpExporter
      grpc:
        endpoint: "localhost:4317"  # Alternative: gRPC protocol

# ===== PROCESSORS =====
# How the collector PROCESSES data before forwarding (optional transformations)
processors:
  batch:
    send_batch_size: 1000  # Batch up to 1000 spans before sending
    timeout: 5s            # Or send after 5 seconds, whichever comes first

# ===== EXPORTERS =====
# Where the collector SENDS processed telemetry data
exporters:
  debug:
    verbosity: detailed    # Print traces to collector's console (for debugging)

  otlp:
    endpoint: jaeger:4317  # Send to Jaeger backend via OTLP gRPC
    tls:
      insecure: true       # Disable TLS for local development (use TLS in production)

# ===== SERVICE PIPELINES =====
# Wire together: receivers → processors → exporters
service:
  pipelines:
    traces:
      receivers: [otlp]              # Accept OTLP traces from Dexto
      processors: [batch]            # Batch them for efficiency
      exporters: [debug, otlp]       # Send to console AND Jaeger
