+
+## Daily Operations Workflow
+
+A recommended daily routine using the Admin Dashboard:
+
+### Morning Check (5 minutes)
+
+1. **Dashboard** → Verify error rate is < 1% and all services are healthy
+2. **DLQ** → Check for overnight failures; investigate and resubmit as needed
+3. **Connectors** → Verify all connectors are healthy (no open circuit breakers)
+4. **In-Flight** → Confirm no stuck messages (no entries older than expected)
+
+### Incident Investigation
+
+1. **Dashboard** → Identify the anomaly (error spike, throughput drop)
+2. **DLQ** → Check error types for the affected time period
+3. **Message Flow** → Trace a specific failing message to find the broken step
+4. **Connectors** → Check if a downstream system is unhealthy
+5. **Audit Log** → Check if any configuration change coincided with the incident
+6. **Control Bus** → Pause affected consumers while investigating (if needed)
+7. **Replay** → Resubmit affected messages after fixing the root cause
+
+### Configuration Change
+
+1. **Config / Feature Flags** → Make the change
+2. **Audit Log** → Verify the change was recorded
+3. **Test Messages** → Submit a test message to verify behavior
+4. **Message Flow** → Track the test message through the pipeline

+```
+
+### Step 4 — Configure Ingress
+
+```yaml
+# deploy/kustomize/overlays/production/ingress.yaml
+apiVersion: networking.k8s.io/v1
+kind: Ingress
+metadata:
+ name: eip-ingress
+ namespace: eip
+ annotations:
+ nginx.ingress.kubernetes.io/rewrite-target: /
+spec:
+ ingressClassName: nginx
+ tls:
+ - hosts:
+ - eip.yourdomain.com
+ secretName: eip-tls
+ rules:
+ - host: eip.yourdomain.com
+ http:
+ paths:
+ - path: /api/gateway
+ pathType: Prefix
+ backend:
+ service:
+ name: gateway-api
+ port:
+ number: 80

+
+## 5. Broker Configuration
+
+The platform supports four message brokers. Choose based on your workload.
+
+### NATS JetStream (Default)
+
+Best for: Local development, cloud deployments, low-latency task delivery.
+
+```json
+{
+ "Broker": {
+ "Type": "nats",
+ "Nats": {
+ "Url": "nats://localhost:4222"
+ }
+ }
+}
+```
+
+### Apache Kafka
+
+Best for: High-throughput event streaming, audit logs, analytics fan-out.
+
+```json
+{
+ "Broker": {
+ "Type": "kafka",
+ "Kafka": {
+ "BootstrapServers": "localhost:9092"
+ }
+ }
+}
+```
+
+### Apache Pulsar
+
+Best for: Large-scale production with recipient-based ordering via Key_Shared subscriptions.
+
+```json
+{
+ "Broker": {
+ "Type": "pulsar",
+ "Pulsar": {
+ "ServiceUrl": "pulsar://localhost:6650"
+ }
+ }
+}
+```
+
+### PostgreSQL
+
+Best for: Simpler deployments without dedicated broker infrastructure.
+
+```json
+{
+ "Broker": {
+ "Type": "postgres",
+ "Postgres": {
+ "ConnectionString": "Host=localhost;Database=eip;Username=eip;Password=secret"
+ }
+ }
+}
+```
+
+### Switching Brokers
+
+The broker is a deployment-time configuration choice. Integration code runs unchanged on all four brokers. Change the `Broker:Type` setting in `appsettings.json` or via environment variable:
+
+```bash
+export Broker__Type=kafka
+```
+
+---
+
+## 6. Infrastructure Services
+
+### Cassandra
+
+The distributed storage layer for message payloads, audit logs, and workflow metadata.
+
+**Keyspace creation** (auto-provisioned on first run in development):
+```cql
+CREATE KEYSPACE IF NOT EXISTS eip_platform
+WITH REPLICATION = {
+ 'class': 'SimpleStrategy',
+ 'replication_factor': 1
+};
+```
+
+**Production keyspace** (NetworkTopologyStrategy):
+```cql
+CREATE KEYSPACE IF NOT EXISTS eip_platform
+WITH REPLICATION = {
+ 'class': 'NetworkTopologyStrategy',
+ 'datacenter1': 3
+};
+```
+
+### Temporal
+
+Workflow orchestration engine. Manages durable workflow execution with automatic retry, compensation, and resume-after-failure.
+
+**Namespace creation:**
+```bash
+temporal operator namespace create eip-production
+```
+
+### Ollama
+
+Self-hosted AI runtime for RAG-powered knowledge retrieval and message trace analysis.
+
+**Verify Ollama is available:**
+```bash
+curl http://localhost:15434/api/version
+```
+
+---
+
+## 7. Admin Web Frontend
+
+The Admin.Web is a Vue 3 single-page application with 19 pages.
+
+### Development Mode
+
+```bash
+cd src/Admin.Web/clientapp
+npm install
+npm run dev
+```
+
+The dev server proxies API calls to Admin.Api automatically.
+
+### Production Build
+
+```bash
+cd src/Admin.Web/clientapp
+npm run build
+```
+
+The built files are served by the Admin.Web ASP.NET host.
+
+### Running Frontend Tests
+
+```bash
+cd src/Admin.Web/clientapp
+npx vitest run
+```
+
+Expected: 100 tests passing across 16 test files.
+
+---
+
+## 8. Security Configuration
+
+### API Key Authentication
+
+The Admin API requires an API key for all requests:
+
+```json
+{
+ "AdminApi": {
+ "ApiKey": "your-secure-api-key-minimum-32-characters"
+ }
+}
+```
+
+Pass the key in requests:
+```bash
+curl -H "X-API-Key: your-secure-api-key" http://localhost:15180/api/admin/status
+```
+
+### Secret Management
+
+Configure a secret provider for production:
+
+**Azure Key Vault:**
+```json
+{
+ "Security": {
+ "Secrets": {
+ "Provider": "AzureKeyVault",
+ "VaultUri": "https://your-vault.vault.azure.net/"
+ }
+ }
+}
+```
+
+**HashiCorp Vault:**
+```json
+{
+ "Security": {
+ "Secrets": {
+ "Provider": "HashiCorpVault",
+ "Address": "https://vault.internal:8200",
+ "MountPath": "secret/eip"
+ }
+ }
+}
+```
+
+### TLS Configuration
+
+For production, enable TLS on all endpoints:
+```json
+{
+ "Kestrel": {
+ "Endpoints": {
+ "Https": {
+ "Url": "https://*:443",
+ "Certificate": {
+ "Path": "/certs/tls.crt",
+ "KeyPath": "/certs/tls.key"
+ }
+ }
+ }
+ }
+}
+```
+
+---
+
+## 9. Observability Stack
+
+### Components
+
+| Component | Purpose | Port |
+|-----------|---------|------|
+| OpenTelemetry Collector | Receives traces, metrics, logs | 4317 (gRPC), 4318 (HTTP) |
+| Loki | Log aggregation and querying | 3100 |
+| Grafana | Dashboards and alerting | 3000 |
+| Jaeger/Tempo | Distributed trace storage and UI | 16686 |

+
+### Grafana Dashboards
+
+Pre-built dashboards are in `deploy/grafana/`:
+
+- **Platform Overview** — Message throughput, error rates, latency percentiles
+- **Broker Health** — Consumer lag, partition distribution, throughput per topic
+- **Workflow Metrics** — Active workflows, execution duration, failure rates
+- **Connector Health** — Delivery success rate, latency, circuit breaker status
+
+### Import Dashboards
+
+```bash
+# Copy dashboards to Grafana provisioning directory
+cp deploy/grafana/*.json /var/lib/grafana/dashboards/
+```
+
+Or import via Grafana UI: Dashboards → Import → Upload JSON.
+
+---
+
+## 10. Verification
+
+After installation, verify the platform is working correctly.
+
+### Health Checks
+
+```bash
+# Gateway API
+curl http://localhost:15100/health/ready
+# Expected: {"status":"Healthy"}
+
+# Admin API
+curl http://localhost:15180/health/ready
+# Expected: {"status":"Healthy"}
+```
+
+### Submit a Test Message
+
+```bash
+curl -X POST http://localhost:15100/api/gateway/submit \
+ -H "Content-Type: application/json" \
+ -d '{
+ "messageType": "HealthCheck",
+ "payload": { "test": true },
+ "businessKey": "install-verify",
+ "priority": "Normal",
+ "intent": "Event"
+ }'
+```
+
+### Run Tests
+
+```bash
+# Unit tests (1995+ tests)
+dotnet test tests/UnitTests
+
+# Contract tests (57 tests)
+dotnet test tests/ContractTests
+
+# Tutorial labs (526 tests)
+dotnet test tests/TutorialLabs

+
+## What You'll Build
+
+By the end of this guide you will have:
+
+1. A running Enterprise Integration Platform on your machine
+2. A message submitted through the Gateway API
+3. That message routed, transformed, and tracked in the Admin Dashboard
+
+---
+
+## Step 1 — Install Prerequisites (5 minutes)
+
+### .NET 10 SDK
+
+```bash
+# Check if installed
+dotnet --version
+# Should start with 10. If not, install:

+```bash
+dotnet new install Aspire.ProjectTemplates
+```
+
+---
+
+## Step 2 — Clone and Build (3 minutes)
+
+```bash
+# Clone the repository
+git clone
+cd My3DLearning/EnterpriseIntegrationPlatform
+
+# Restore NuGet packages
+dotnet restore
+
+# Build the entire solution
+dotnet build
+```
+
+You should see `Build succeeded. 0 Warning(s) 0 Error(s)`.

+
+---
+
+## Step 3 — Start the Platform (2 minutes)
+
+```bash
+cd src/AppHost
+dotnet run
+```
+
+Watch the console output. Aspire will:
+
+1. Pull and start Docker containers (Kafka, NATS, Temporal, Cassandra, Ollama, Loki, Grafana)
+2. Start all platform services (Gateway.Api, Admin.Api, Admin.Web, OpenClaw.Web, workers)
+3. Display the **Aspire Dashboard URL** — open it in your browser
+
+The Aspire Dashboard shows all running services, their health status, logs, and traces.
+
+> **Tip:** First run takes longer because Docker pulls container images. Subsequent starts are much faster.
+
+---
+
+## Step 4 — Submit Your First Message (2 minutes)
+
+Open a new terminal and send a message to the Gateway API:
+
+```bash
+curl -X POST http://localhost:15100/api/gateway/submit \
+ -H "Content-Type: application/json" \
+ -d '{
+ "messageType": "OrderCreated",
+ "payload": {
+ "orderId": "ORD-001",
+ "customer": "Alice",
+ "total": 99.99,
+ "items": [
+ { "sku": "WIDGET-A", "quantity": 2, "price": 49.99 }
+ ]
+ },
+ "businessKey": "ORD-001",
+ "priority": "Normal",
+ "intent": "Event"
+ }'
+```
+
+You'll get a response like:
+
+```json
+{
+ "messageId": "abc123-...",
+ "correlationId": "def456-...",
+ "status": "Accepted"
+}
+```
+
+The Gateway has:
+- ✅ Validated your request
+- ✅ Applied rate limiting
+- ✅ Wrapped the payload in an `IntegrationEnvelope`
+- ✅ Published to the message broker
+- ✅ Returned the `MessageId` and `CorrelationId` for tracking
+
+---
+
+## Step 5 — Track Your Message (3 minutes)
+
+### Via OpenClaw ("Where Is My Message?")
+
+Open the OpenClaw web UI (check the Aspire Dashboard for its URL, typically `http://localhost:15300`).
+
+Enter your business key `ORD-001` or the `correlationId` from the response. You'll see:
+
+- Full lifecycle timeline (received → validated → routed → transformed → delivered)
+- Current status
+- AI-generated trace analysis (when Ollama is available)
+
+### Via the Admin Dashboard
+
+Open the Admin.Web dashboard (check the Aspire Dashboard for its URL, typically `http://localhost:15200`).
+
+Navigate to:
+
+1. **Dashboard** — See the message count increment in real-time
+2. **Message Flow** — See your message's flow through the pipeline on a visual timeline
+3. **Messages** — Search by message ID or correlation ID to inspect the full envelope
+4. **In-Flight** — See currently processing messages (if you send multiple quickly)
+
+### Via the Admin API
+
+```bash
+# Track by correlation ID
+curl http://localhost:15180/api/admin/messages/correlation/{correlationId}
+
+# Track by business key
+curl http://localhost:15180/api/admin/messages/business/ORD-001
+```
+
+---
+
+## What Just Happened?
+
+Here's the end-to-end flow your message took:
+
+```
+Your curl request
+ │
+ ▼
+┌──────────────────┐
+│ Gateway.Api │ Validated, rate-limited, wrapped in IntegrationEnvelope
+└────────┬─────────┘
+ │
+ ▼
+┌──────────────────┐
+│ Message Broker │ Published to NATS JetStream (default broker)
+│ (NATS/Kafka) │
+└────────┬─────────┘
+ │
+ ▼
+┌──────────────────┐
+│ Temporal │ Workflow started: validate → route → transform → deliver
+│ Workflow │
+└────────┬─────────┘
+ │
+ ▼
+┌──────────────────┐
+│ Activities │ Content-based routing, transformations, enrichment
+└────────┬─────────┘
+ │
+ ▼
+┌──────────────────┐
+│ Connector │ Delivered to target system (HTTP, SFTP, Email, or File)
+└────────┬─────────┘
+ │
+ ▼
+┌──────────────────┐
+│ Cassandra │ Message, audit trail, and lifecycle events stored
+└──────────────────┘
+```
+
+Every step was:
+- **Traced** — OpenTelemetry captured distributed traces across all services
+- **Logged** — Structured logs correlated with trace IDs stored in Loki
+- **Metered** — Prometheus metrics recorded throughput, latency, and error rates

+
+---
+
+## Troubleshooting
+
+### Aspire fails to start
+
+1. **Docker not running** — Start Docker Desktop first
+2. **Port conflict** — Check that nothing is using the 15xxx port range
+3. **Missing SDK** — Run `dotnet --list-sdks` and verify .NET 10.x is installed
+
+### curl returns connection refused
+
+The Gateway.Api may still be starting. Wait 30 seconds after Aspire starts and try again. Check the Aspire Dashboard for service health.
+
+### "No brokers available" error
+
+Docker containers are still starting. Wait for the Aspire Dashboard to show all services as "Running" before submitting messages.
+
+### Vue frontend not loading
+
+```bash
+cd src/Admin.Web/clientapp
+npm install
+npm run build
+```
+
+Then restart the Aspire AppHost.
