+## Implementation Status: COMPLETED
+
+**Completed Date:** 2025-12-29
+
+### Actual Implementation
+
+The implementation followed a federated query pattern different from the original design:
+
+#### Files Created:
+| File | Description |
+|------|-------------|
+| `src/observability-collector/app/collectors/loki_collector.py` | Loki LogQL collector with auth |
+| `src/observability-collector/app/collectors/tempo_collector.py` | Tempo trace collector with OTLP parsing |
+| `src/observability-collector/app/services/logs_service.py` | Federated log query service |
+| `src/observability-collector/app/services/traces_service.py` | Federated trace query service |
+| `src/observability-collector/app/api/logs.py` | Logs API endpoints |
+| `src/observability-collector/app/api/traces.py` | Traces API endpoints |
+
+#### API Endpoints Implemented:
+- `POST /api/v1/logs/query` - Execute LogQL query
+- `POST /api/v1/logs/query_range` - Execute LogQL range query
+- `GET /api/v1/logs/labels` - Get available labels
+- `GET /api/v1/logs/label/{name}/values` - Get label values
+- `POST /api/v1/traces/search` - Search traces
+- `GET /api/v1/traces/services` - List services with traces
+- `GET /api/v1/traces/operations` - Get operations for service
+- `GET /api/v1/traces/dependencies` - Get service dependency graph
+- `GET /api/v1/traces/{trace_id}` - Get trace by ID
+- `GET /api/v1/traces/{trace_id}/spans` - Get spans for trace
+
+#### Bug Fixed During Testing:
+- Route order issue in traces.py - static routes (`/services`, `/operations`, `/dependencies`) were matched by `/{trace_id}`. Fixed by reordering routes.
+
+#### Sandbox Testing:
+- Deployed to sandbox01.narlabs.io
+- All endpoints tested and working
+- Returns empty data (expected - no clusters with Loki/Tempo configured)

+
+**Completed Date:** 2025-12-29
+
+### Actual Implementation
+
+Enhanced the existing `gpu_collector.py` with real Kubernetes API integration:
+
+#### Key Features:
+1. **Node Discovery**: Lists GPU nodes via `nvidia.com/gpu` resource labels
+2. **Pod Discovery**: Finds nvidia-driver-daemonset pods on GPU nodes

+4. **CSV Parsing**: Parses nvidia-smi CSV output for GPU metrics
+5. **Mock Data Fallback**: Returns mock data when real GPUs unavailable
+
+#### Files Modified:
+| File | Description |
+|------|-------------|
+| `src/observability-collector/app/collectors/gpu_collector.py` | Enhanced GPU collector with real K8s API |
+

+## Implementation Status: COMPLETED
+
+**Completed:** 2025-12-29
+
+### Files Created
+
+| File | Description |
+|------|-------------|
+| `src/realtime-streaming/app/services/heartbeat.py` | HeartbeatManager with 30s ping, 10s pong timeout, 3 missed pong detection |
+| `src/realtime-streaming/app/services/backpressure.py` | BackpressureHandler with 1000 message buffer, high/low watermarks |
+| `src/api-gateway/app/api/websocket_proxy.py` | WebSocket proxy with OAuth authentication |
+
+### Files Modified
+
+| File | Changes |
+|------|---------|
+| `src/realtime-streaming/app/api/websocket.py` | Integrated heartbeat and backpressure managers |
+| `src/realtime-streaming/app/main.py` | Start/stop heartbeat manager in lifespan |
+| `src/realtime-streaming/app/services/__init__.py` | Export new services |
+| `src/api-gateway/app/main.py` | Include WebSocket proxy router |
+
+### Key Implementation Details
+
+1. **HeartbeatManager** (`heartbeat.py`):
+   - Tracks connection state with last_ping_sent and last_pong_received
+   - Async heartbeat loop runs every 30 seconds
+   - Closes connections after 3 consecutive missed pongs
+   - Singleton instance shared across all WebSocket connections
+
+2. **BackpressureHandler** (`backpressure.py`):
+   - Per-connection MessageBuffer with configurable max size (default 1000)
+   - Drop policy: oldest messages dropped when buffer full
+   - High watermark (80%): pauses event production for connection
+   - Low watermark (50%): resumes event production
+   - Tracks consumer metrics: buffer size, dropped messages, average latency
+
+3. **WebSocket Proxy** (`websocket_proxy.py`):
+   - Extracts token from query params or Sec-WebSocket-Protocol header
+   - Validates token via OAuth middleware before accepting connection
+   - Bidirectional message forwarding to backend realtime-streaming service
+   - Fallback handling when websockets library unavailable
