主机名、操作系统、架构、运行时间 + +所有数据使用 `gopsutil` 库采集。 + +### 性能优化 + +#### 自适应采集频率 + +**位置**: `internal/agent/adaptive.go` + +```go +// 根据 CPU 使用率动态调整采集频率 +func (ac *AdaptiveCollector) AdjustInterval(cpuPercent float64) time.Duration { + if cpuPercent > 70 { + return 30 * time.Second // 高负载，降低频率 + } else if cpuPercent < 30 { + return 2 * time.Second // 低负载，提高频率 + } + return 5 * time.Second // 正常频率 +} +``` + +#### 内存池优化 + +**位置**: `internal/agent/mempool.go` + +```go +// JSON 序列化使用内存池，减少内存分配 +func OptimizedJSONMarshal(v interface{}) ([]byte, error) { + buf := GlobalMemoryPool.GetBuffer() + defer GlobalMemoryPool.PutBuffer(buf) + + encoder := json.NewEncoder(buf) + err := encoder.Encode(v) + return append([]byte(nil), buf.Bytes()...), err +} +``` + +## 2. 数据传输阶段 + +### 发送队列机制 + +**位置**:

Dashboard 接收流程 + +**位置**: `internal/dashboard/websocket_manager.go` + +```go +// Melody 处理消息 +func (wm *WebSocketManager) HandleMessage(s *melody.Session, msg []byte) { + // 1. 反序列化 + var serverInfo

wm.saveServerInfo(&serverInfo) + + // 4. 广播到前端 + wm.broadcastToFrontend(&serverInfo) + + // 5. 更新统计 + wm.updateStats(s, len(msg)) +} +``` + +### 内存存储 + +**位置**: `internal/dashboard/global/global.go` + +```go +// 使用并发安全的 Map 存储 +var ServerStatusInfoMap = cmap.New[*model.ServerInfo]() + +// 保存数据 +func (wm *WebSocketManager) saveServerInfo(info *model.ServerInfo) { + ServerStatusInfoMap.Set(info.ServerId, info) +} + +// 查询数据 +func GetServerInfo(serverID string) (*model.ServerInfo, bool) { + return ServerStatusInfoMap.Get(serverID) +} +``` + +### 连接状态跟踪 + +```go

+type ConnectionInfo struct { + ServerID string + ConnectAt time.Time + LastSeen time.Time + MessageCount int64 + BytesReceived int64 +} +``` + +## 4. 数据广播阶段 + +### 前端 WebSocket 管理 + +**位置**: `internal/dashboard/frontend_websocket_manager.go` + +```go +// 广播到所有前端连接 +func (fwm *FrontendWebSocketManager) BroadcastServerInfo(info *model.ServerInfo) { + data, err := json.Marshal(info) + if err

+``` + +### 触发时机 + +``` +Agent 上报数据 + ↓ +Dashboard 接收 + ↓ +立即广播到前端 ←─ 实时性保证 + ↓ +所有前端连接收到更新 +``` + +## 5. 前端展示阶段 + +### WebSocket 客户端 + +**位置**: `web/src/api/websocket.ts` + +```typescript +class WebSocketClient { + private ws: WebSocket | null = null; + + connect(url: string) { + this.ws = new WebSocket(url); + + this.ws.onmessage = (event) => { + const data = JSON.parse(event.data); + // 更新 Vue 状态 + store.updateServerInfo(data); + }; + } +} +``` + +### Vue 状态更新 + +**位置**: `web/src/stores/serverStore.ts` + +```typescript +export const useServerStore = defineStore('server', { + state: ()

+sudo systemctl enable sss-dashboard +sudo systemctl status sss-dashboard +``` + +--- + +## 📱 第二步：部署 Agent + +### 方式 1：使用安装脚本（推荐） + +#### Linux / macOS / FreeBSD + +```bash +# 一键安装 +curl -fsSL https://raw.githubusercontent.com/ruanun/simple-server-status/main/scripts/install-agent.sh | sudo bash +``` + +安装完成后，编辑配置文件： + +```bash +sudo nano /etc/sssa/sss-agent.yaml +``` + +**必须修改的配置项：** + +```yaml +# Dashboard 地址（替换为你的 Dashboard IP 或域名） +serverAddr: ws://your-dashboard-ip:8900/ws-report + +# 服务器唯一标识符（必须与 Dashboard 配置中的 servers.id 一致） +serverId: web-server-01 + +# 认证密钥（必须与 Dashboard 配置中的 servers.secret 一致） +authSecret: "your-strong-secret-key-here" + +# 可选配置 +logLevel: info +disableIP2Region: false +``` + +启动 Agent： + +```bash +sudo systemctl start sssa +sudo systemctl enable

+修改配置后，通过服务管理器启动 SSSA 服务： + +```powershell +# 启动服务 +Start-Service -Name "SSSA" + +# 查看服务状态 +Get-Service -Name "SSSA" +``` + +### 方式 2：手动安装 + +手动安装的详细步骤请参考：[手动安装指南](deployment/manual.md) + +--- + +## ✅ 第三步：验证连接 + +### 3.1 检查 Dashboard + +1. 访问 Dashboard Web 界面：`http://your-server-ip:8900` +2. 检查服务器是否显示为**在线**状态 +3. 查看是否有实时数据更新 + +### 3.2 检查 Agent + +**Linux / macOS / FreeBSD:** + +```bash +# 查看 Agent 状态 +sudo systemctl status sssa + +# 查看日志（应该看到 "连接成功" 的消息） +sudo journalctl -u sssa -n 50 +``` + +**Windows:** + +```powershell +# 查看服务状态 +Get-Service -Name "SSSA" + +# 查看 Windows 事件日志 +Get-EventLog -LogName Application -Source "SSSA" -Newest 20 +``` + +### 3.3 连接失败排查 + +如果服务器显示离线，请按以下步骤排查： + +#### ① 检查 Dashboard 是否正常运行 + +```bash +# Docker +docker ps | grep sssd +docker logs sssd + +# 二进制 +sudo systemctl status sss-dashboard +sudo journalctl -u sss-dashboard -n 50 +``` + +#### ② 检查 Agent 是否正常运行 + +```bash +# Linux +sudo systemctl status sssa +sudo journalctl -u sssa -n 50 + +# Windows +Get-Service -Name "SSSA" +``` + +#### ③ 验证配置文件 + +确认以下配置项完全一致： + +- Dashboard 的 `servers.id` ↔ Agent 的 `serverId` +- Dashboard 的 `servers.secret` ↔ Agent 的 `authSecret` +- Agent 的 `serverAddr` 格式正确：`ws://dashboard-ip:8900/ws-report` +- `serverAddr` 路径与 Dashboard 的 `webSocketPath` 一致（默认 `/ws-report`） + +#### ④ 检查网络连接 + +```bash +# 测试 Dashboard 端口是否可访问 +telnet your-dashboard-ip 8900 +# 或 +nc -zv your-dashboard-ip 8900 +``` + +#### ⑤ 检查防火墙 + +```bash +# Ubuntu/Debian +sudo ufw status +sudo ufw allow 8900 + +# CentOS/RHEL +sudo firewall-cmd --list-all +sudo firewall-cmd
