+# Metrics in the Project
+
+## How Metrics Work
+The project uses Prometheus for metrics collection and Grafana for visualization. Metrics are collected using Pushgateway.
+
+## Metrics Collection Architecture:
+1. Workers (C++) collect local counters:
+    - `packets_received`- packets received
+    - `packets_passed `- packets allowed through
+    - `packets_dropped` - packets blocked
+2. MetricsCollector periodically (every 5 seconds) pushes metrics to Pushgateway via HTTP POST
+3. Prometheus scrapes Pushgateway (every 5 seconds) and stores metrics in a time-series database
+4. Grafana connects to Prometheus and displays metrics on dashboards
+
+## Metrics Format:
+```text
+packets_received{worker_id="worker-1"} 12345
+packets_passed{worker_id="worker-1"} 10000
+packets_dropped{worker_id="worker-1"} 2345
+```
+
+# How to View Metrics
+
+## Via Grafana
+
+
+**On our test stand**:  
+Open in browser: http://localhost:3000
+
+**On the board**:  
+Open in browser: http://<BOARD_IP>:3000  
+Where <BOARD_IP> is the IP address of the board where Grafana is deployed.  
+Default login: `admin / admin`  
+Available dashboards:
+- Overall statistics across all workers
+- Detailed analysis per worker
+- Real-time graphs
