- Add PromptGenerationTraceInfo trace entity with operation_type field
- Implement telemetry for rule-generate, code-generate, structured-output, instruction-modify operations
- Emit metrics: tokens (total/input/output), duration histogram, requests counter, errors counter
- Emit structured logs with model info and operation context
- Content redaction controlled by ENTERPRISE_INCLUDE_CONTENT env var
- Fix user_id propagation in TraceTask kwargs
- Fix latency calculation when llm_result is None
No spans exported - metrics and logs only for lightweight observability.
- Create dedicated MeterProvider instance (independent from ext_otel.py)
- Add create_metric_exporter() to _ExporterFactory with HTTP/gRPC support
- Enterprise metrics now work without requiring standard OTEL to be enabled
- Add MeterProvider shutdown to cleanup lifecycle
- Update module docstring to reflect full independence (Tracer, Logger, Meter)
Only export structured telemetry logs, not all application logs. The attach_log_handler method now attaches to the 'dify.telemetry' logger instead of the root logger.
- Add ENTERPRISE_OTLP_PROTOCOL config (http/grpc, default: http)
- Introduce _ExporterFactory class for protocol-agnostic exporter creation
- Support both HTTP and gRPC OTLP endpoints for traces and logs
- Refactor endpoint path handling into factory methods
- Add ENTERPRISE_OTEL_LOGS_ENABLED and ENTERPRISE_OTLP_LOGS_ENDPOINT config options
- Implement EnterpriseLoggingHandler for log record translation with trace/span ID parsing
- Add LoggerProvider and BatchLogRecordProcessor for OTLP log export
- Correlate telemetry logs with spans via span_id_source parameter
- Attach log handler during enterprise telemetry initialization
