+### Manual commands
+
+<details>
+<summary>Show manual setup and run steps</summary>
+
+These commands assume you start from the repository root.
+
+1. Start the docker-compose stack.
+
+   The backend requires middleware, including PostgreSQL, Redis, and Weaviate, which can be started together using `docker-compose`.
+
+   ```bash
+   cp docker/middleware.env.example docker/middleware.env
+   # Use mysql or another vector database profile if you are not using postgres/weaviate.
+   docker compose -f docker/docker-compose.middleware.yaml --profile postgresql --profile weaviate -p dify up -d
+   ```
+
+1. Copy env files.
+
+   ```bash
+   cp api/.env.example api/.env
+   cp web/.env.example web/.env.local
+   ```
+
+1. Install UV if needed.
+
+   ```bash
+   pip install uv
+   # Or on macOS
+   brew install uv
+   ```
+
+1. Install API dependencies.
+
+   ```bash
+   cd api
+   uv sync --group dev
+   ```
+
+1. Install web dependencies.
+
+   ```bash
+   cd web
+   pnpm install
+   cd ..
+   ```
+
+1. Start backend (runs migrations first, in a new terminal).
+
+   ```bash
+   cd api
+   uv run flask db upgrade
+   uv run flask run --host 0.0.0.0 --port=5001 --debug
+   ```
+
+1. Start Dify [web](../web) service (in a new terminal).
+
+   ```bash
+   cd web
+   pnpm dev:inspect
+   ```
+
+1. Set up your application by visiting `http://localhost:3000`.
+
+1. Optional: start the worker service (async tasks, in a new terminal).
+
+   ```bash
+   cd api
+   # Note: enterprise_telemetry queue is only used in Enterprise Edition
+   uv run celery -A app.celery worker -P threads -c 2 --loglevel INFO -Q dataset,priority_dataset,priority_pipeline,pipeline,mail,ops_trace,app_deletion,plugin,workflow_storage,conversation,workflow,schedule_poller,schedule_executor,triggered_workflow_dispatcher,trigger_refresh_executor,retention,enterprise_telemetry
+   ```
+
+1. Optional: start Celery Beat (scheduled tasks, in a new terminal).
+
+   ```bash
+   cd api
+   uv run celery -A app.celery beat
+   ```

+
+## Counters
+
+All counters are cumulative and emitted at 100% accuracy.
+
+### Token Counters
+
+| Metric | Unit | Description |
+|--------|------|-------------|
+| `dify.tokens.total` | `{token}` | Total tokens consumed |
+| `dify.tokens.input` | `{token}` | Input (prompt) tokens |
+| `dify.tokens.output` | `{token}` | Output (completion) tokens |
+
+**Labels:**
+
+- `tenant_id`, `app_id`, `operation_type`, `model_provider`, `model_name`, `node_type` (if node_execution)
+
+⚠️ **Warning:** `dify.tokens.total` at workflow level includes all node tokens. Filter by `operation_type` to avoid double-counting.
+
+#### Token Hierarchy & Query Patterns
+
+Token metrics are emitted at multiple layers. Understanding the hierarchy prevents double-counting:
+
+```
+App-level total
+├── workflow          ← sum of all node_execution tokens (DO NOT add both)
+│   └── node_execution ← per-node breakdown
+├── message           ← independent (non-workflow chat apps only)
+├── rule_generate     ← independent helper LLM call
+├── code_generate     ← independent helper LLM call
+├── structured_output ← independent helper LLM call
+└── instruction_modify← independent helper LLM call
+```
+
+**Key rule:** `workflow` tokens already include all `node_execution` tokens. Never sum both.
+
+**Available labels on token metrics:** `tenant_id`, `app_id`, `operation_type`, `model_provider`, `model_name`, `node_type`.
+App name is only available on span attributes (`dify.app.name`), not metric labels — use `app_id` for metric queries.
+
+**Common queries** (PromQL):
+
+```promql
+# ── Totals ──────────────────────────────────────────────────
+# App-level total (exclude node_execution to avoid double-counting)
+sum by (app_id) (dify_tokens_total{operation_type!="node_execution"})
+
+# Single app total
+sum (dify_tokens_total{app_id="<app_id>", operation_type!="node_execution"})
+
+# Per-tenant totals
+sum by (tenant_id) (dify_tokens_total{operation_type!="node_execution"})
+
+# ── Drill-down ──────────────────────────────────────────────
+# Workflow-level tokens for an app
+sum (dify_tokens_total{app_id="<app_id>", operation_type="workflow"})
+
+# Node-level breakdown within an app
+sum by (node_type) (dify_tokens_total{app_id="<app_id>", operation_type="node_execution"})
+
+# Model breakdown for an app
+sum by (model_provider, model_name) (dify_tokens_total{app_id="<app_id>"})
+
+# Input vs output per model
+sum by (model_name) (dify_tokens_input_total{app_id="<app_id>"})
+sum by (model_name) (dify_tokens_output_total{app_id="<app_id>"})
+
+# ── Rates ───────────────────────────────────────────────────
+# Token consumption rate (per hour)
+sum(rate(dify_tokens_total{operation_type!="node_execution"}[1h]))
+
+# Per-app consumption rate
+sum by (app_id) (rate(dify_tokens_total{operation_type!="node_execution"}[1h]))
+```
+
+**Finding `app_id` from app name** (trace query — Tempo / Jaeger):
+
+```
+{ resource.dify.app.name = "My Chatbot" } | select(resource.dify.app.id)
+```

+# Dify Enterprise Telemetry
+
+This document provides an overview of the Dify Enterprise OpenTelemetry (OTEL) exporter and how to configure it for integration with observability stacks like Prometheus, Grafana, Jaeger, or Honeycomb.
+
+## Overview
+
+Dify Enterprise uses a "slim span + rich companion log" architecture to provide high-fidelity observability without overwhelming trace storage.
+
+- **Traces (Spans)**: Capture the structure, identity, and timing of high-level operations (Workflows and Nodes).
+- **Structured Logs**: Provide deep context (inputs, outputs, metadata) for every event, correlated to spans via `trace_id` and `span_id`.
+- **Metrics**: Provide 100% accurate counters and histograms for usage, performance, and error tracking.
+
+### Signal Architecture
+
+```mermaid
+graph TD
+    A[Workflow Run] -->|Span| B(dify.workflow.run)
+    A -->|Log| C(dify.workflow.run detail)
+    B ---|trace_id| C
+    
+    D[Node Execution] -->|Span| E(dify.node.execution)
+    D -->|Log| F(dify.node.execution detail)
+    E ---|span_id| F
+    
+    G[Message/Tool/etc] -->|Log| H(dify.* event)
+    G -->|Metric| I(dify.* counter/histogram)
+```
+
+## Configuration
+
+The Enterprise OTEL exporter is configured via environment variables.
+
+| Variable | Description | Default |
+|----------|-------------|---------|
+| `ENTERPRISE_ENABLED` | Master switch for all enterprise features. | `false` |
+| `ENTERPRISE_TELEMETRY_ENABLED` | Master switch for enterprise telemetry. | `false` |
+| `ENTERPRISE_OTLP_ENDPOINT` | OTLP collector endpoint (e.g., `http://otel-collector:4318`). | - |
+| `ENTERPRISE_OTLP_HEADERS` | Custom headers for OTLP requests (e.g., `x-scope-orgid=tenant1`). | - |
+| `ENTERPRISE_OTLP_PROTOCOL` | OTLP transport protocol (`http` or `grpc`). | `http` |
+| `ENTERPRISE_OTLP_API_KEY` | Bearer token for authentication. | - |
+| `ENTERPRISE_INCLUDE_CONTENT` | Whether to include sensitive content (inputs/outputs) in logs. | `true` |
+| `ENTERPRISE_SERVICE_NAME` | Service name reported to OTEL. | `dify` |
+| `ENTERPRISE_OTEL_SAMPLING_RATE` | Sampling rate for traces (0.0 to 1.0). Metrics are always 100%. | `1.0` |
+
+## Correlation Model
+
+Dify uses deterministic ID generation to ensure signals are correlated across different services and asynchronous tasks.
+
+### ID Generation Rules
+
+- `trace_id`: Derived from the correlation ID (workflow_run_id or node_execution_id for drafts) using `int(UUID(correlation_id))`
+- `span_id`: Derived from the source ID using the lower 64 bits of `UUID(source_id)`
+
+### Scenario A: Simple Workflow
+
+A single workflow run with multiple nodes. All spans and logs share the same `trace_id` (derived from `workflow_run_id`).
+
+```
+trace_id = UUID(workflow_run_id)
+├── [root span] dify.workflow.run (span_id = hash(workflow_run_id))
+│   ├── [child] dify.node.execution - "Start" (span_id = hash(node_exec_id_1))
+│   ├── [child] dify.node.execution - "LLM" (span_id = hash(node_exec_id_2))
+│   └── [child] dify.node.execution - "End" (span_id = hash(node_exec_id_3))
+```
+
+### Scenario B: Nested Sub-Workflow
+
+A workflow calling another workflow via a Tool or Sub-workflow node. The child workflow's spans are linked to the parent via `parent_span_id`. Both workflows share the same trace_id.
+
+```
+trace_id = UUID(outer_workflow_run_id)     ← shared across both workflows
+├── [root] dify.workflow.run (outer) (span_id = hash(outer_workflow_run_id))
+│   ├── dify.node.execution - "Start Node"
+│   ├── dify.node.execution - "Tool Node" (triggers sub-workflow)
+│   │   └── [child] dify.workflow.run (inner) (span_id = hash(inner_workflow_run_id))
+│   │       ├── dify.node.execution - "Inner Start"
+│   │       └── dify.node.execution - "Inner End"
+│   └── dify.node.execution - "End Node"
+```
+
+**Key attributes for nested workflows:**
+
+- Inner workflow's `dify.parent.trace_id` = outer `workflow_run_id`
+- Inner workflow's `dify.parent.node.execution_id` = tool node's `execution_id`
+- Inner workflow's `dify.parent.workflow.run_id` = outer `workflow_run_id`
+- Inner workflow's `dify.parent.app.id` = outer `app_id`
+
+### Scenario C: Draft Node Execution
+
+A single node run in isolation (debugger/preview mode). It creates its own trace where the node span is the root.
+
+```
+trace_id = UUID(node_execution_id)   ← own trace, NOT part of any workflow
+└── dify.node.execution.draft (span_id = hash(node_execution_id))
+```
+
+**Key difference:** Draft executions use `node_execution_id` as the correlation_id, so they are NOT children of any workflow trace.
+
+## Content Gating
+
+When `ENTERPRISE_INCLUDE_CONTENT` is set to `false`, sensitive content attributes (inputs, outputs, queries) are replaced with reference strings (e.g., `ref:workflow_run_id=...`) to prevent data leakage to the OTEL collector.
+
+**Reference String Format:**
+
+```
+ref:{id_type}={uuid}
+```
+
+**Examples:**
+
+```
+ref:workflow_run_id=550e8400-e29b-41d4-a716-446655440000
+ref:node_execution_id=660e8400-e29b-41d4-a716-446655440001
+ref:message_id=770e8400-e29b-41d4-a716-446655440002
+```
+
+To retrieve actual content when gating is enabled, query the Dify database using the provided UUID.
