- 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
Enables distributed tracing for nested workflows across all trace providers
(Langfuse, LangSmith, community providers). When a workflow invokes another
workflow via workflow-as-tool, the child workflow now includes parent context
attributes that allow trace systems to reconstruct the full execution tree.
Changes:
- Add parent_trace_context field to WorkflowTool
- Set parent context in tool node when invoking workflow-as-tool
- Extract and pass parent context through app generator
This is a community enhancement (ungated) that improves distributed tracing
for all users. Parent context includes: trace_id, node_execution_id,
workflow_run_id, and app_id.
When setting a new default credential in enterprise mode, the code was
only clearing is_default for credentials matching the current user_id.
This caused issues when:
1. Enterprise credential A (synced with system user_id) was default
2. User sets local credential B as default
3. A still had is_default=true (different user_id)
4. Both A and B were considered defaults
The fix removes user_id from the filter only for enterprise deployments,
since enterprise credentials may have different user_id than local ones.
Non-enterprise behavior is unchanged to avoid breaking existing setups.
Fixes EE-1511
