 # Implementation Hints and Learnings
 
+## Network Metrics Implementation (2025-06-23)
+
+### SmartProxy Metrics API Integration
+- Updated to use new SmartProxy metrics API (v19.6.7)
+- Use `getMetrics()` for detailed metrics with grouped methods:
+  ```typescript
+  const metrics = smartProxy.getMetrics();
+  metrics.connections.active()      // Current active connections
+  metrics.throughput.instant()      // Real-time throughput {in, out}
+  metrics.connections.topIPs(10)    // Top 10 IPs by connection count
+  ```
+- Use `getStatistics()` for basic stats
+
+### Network Traffic Display
+- All throughput values shown in bits per second (kbit/s, Mbit/s, Gbit/s)
+- Conversion: `bytesPerSecond * 8 / 1000000` for Mbps
+- Network graph shows separate lines for inbound (green) and outbound (purple)
+- Throughput tiles and graph use same data source for consistency
+
+### Requests/sec vs Connections
+- Requests/sec shows HTTP request counts (derived from connections)
+- Single connection can handle multiple requests
+- Current implementation tracks connections, not individual requests
+- Trend line shows historical request counts, not throughput
+
