+- Update interval in seconds (default: 60)
+- VictoriaMetrics URL (default: http://localhost:8428)
+
+3. **Enable and start the service:**
+```bash
+sudo systemctl enable nationalgrid-monitor.service
+sudo systemctl start nationalgrid-monitor.service
+```
+
+4. **Check service status:**
+```bash
+sudo systemctl status nationalgrid-monitor.service
+```
+
+5. **View logs:**
