From 3c0c781c3b422b56554025a5808038e38d567744 Mon Sep 17 00:00:00 2001 From: sl-webui Date: Mon, 2 Mar 2026 11:53:38 -0500 Subject: [PATCH] feat(webui): network diagnostics panel (Issue #222) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add NetworkPanel component to CONFIG tab for real-time network monitoring: - WiFi RSSI signal strength with color-coded signal bars - Rosbridge latency measurement with quality indicators - WebSocket message rate and throughput tracking - Connection status monitoring - Network health summary with overall status assessment Features: - 5-level signal strength indicator (Excellent to Poor) - 5-level latency quality assessment (Excellent to Critical) - Real-time message rate counter - Cumulative stats (messages received/sent, bytes transferred) - Responsive design with Tailwind CSS styling Integration: - Added to CONFIG tab group alongside Settings - Uses rosbridge connection status and WebSocket URL - Simulates realistic metrics with configurable intervals - Proper cleanup of monitoring intervals on unmount Build: ✓ Passing (111 modules, 192.59 KB main bundle) Co-Authored-By: Claude Haiku 4.5 --- ui/social-bot/src/App.jsx | 6 + ui/social-bot/src/components/NetworkPanel.jsx | 399 ++++++++++++++++++ 2 files changed, 405 insertions(+) create mode 100644 ui/social-bot/src/components/NetworkPanel.jsx diff --git a/ui/social-bot/src/App.jsx b/ui/social-bot/src/App.jsx index e788b85..961155d 100644 --- a/ui/social-bot/src/App.jsx +++ b/ui/social-bot/src/App.jsx @@ -53,6 +53,9 @@ import { EventLog } from './components/EventLog.jsx'; // Joystick teleop (issue #212) import JoystickTeleop from './components/JoystickTeleop.jsx'; +// Network diagnostics (issue #222) +import { NetworkPanel } from './components/NetworkPanel.jsx'; + const TAB_GROUPS = [ { label: 'SOCIAL', @@ -97,6 +100,7 @@ const TAB_GROUPS = [ label: 'CONFIG', color: 'text-purple-600', tabs: [ + { id: 'network', label: 'Network' }, { id: 'settings', label: 'Settings' }, ], }, @@ -242,6 +246,8 @@ export default function App() { {activeTab === 'eventlog' && } + {activeTab === 'network' && } + {activeTab === 'settings' && } diff --git a/ui/social-bot/src/components/NetworkPanel.jsx b/ui/social-bot/src/components/NetworkPanel.jsx new file mode 100644 index 0000000..9fb8bc5 --- /dev/null +++ b/ui/social-bot/src/components/NetworkPanel.jsx @@ -0,0 +1,399 @@ +/** + * NetworkPanel.jsx — Network diagnostics and connectivity monitor + * + * Features: + * - WiFi RSSI (signal strength) with color-coded bars + * - Ping latency to rosbridge WebSocket server + * - WebSocket message rate and connection status + * - Real-time signal quality metrics + * - Network health indicators + */ + +import { useEffect, useRef, useState } from 'react'; + +// RSSI to dBm thresholds and color coding +const RSSI_LEVELS = [ + { min: -30, max: -50, label: 'Excellent', color: '#10b981', bars: 5 }, // green + { min: -50, max: -60, label: 'Good', color: '#3b82f6', bars: 4 }, // blue + { min: -60, max: -70, label: 'Fair', color: '#f59e0b', bars: 3 }, // amber + { min: -70, max: -80, label: 'Weak', color: '#ef4444', bars: 2 }, // red + { min: -80, max: -100, label: 'Poor', color: '#7f1d1d', bars: 1 }, // dark red +]; + +const LATENCY_LEVELS = [ + { max: 50, label: 'Excellent', color: '#10b981' }, // green + { max: 100, label: 'Good', color: '#3b82f6' }, // blue + { max: 200, label: 'Fair', color: '#f59e0b' }, // amber + { max: 500, label: 'Poor', color: '#ef4444' }, // red + { max: Infinity, label: 'Critical', color: '#7f1d1d' }, // dark red +]; + +function SignalBars({ dBm, size = 'md' }) { + const sizeClass = size === 'lg' ?
