🔍 核心监控功能详解

1. 实时状态Socket监控

FieldStation42通过状态Socket文件实时推送播放状态信息,这是最核心的监控机制:

# 状态Socket文件路径(默认)
status_socket = "/tmp/fs42_status.socket"

# 状态信息JSON格式示例
{
    "status": "playing",           # 播放状态:playing/stuck/stopped
    "network_name": "CBS",         # 电视台名称
    "channel_number": 5,           # 频道号
    "title": "Evening News",       # 当前节目标题
    "timestamp": "2024-01-15T19:30:45",  # 时间戳
    "duration": "00:30:00/01:00:00",     # 播放进度/总时长
    "file_path": "/content/CBS/evening_news.mp4"  # 文件路径
}
状态类型说明
状态值含义触发条件严重级别
playing正常播放节目正常播放正常
stuck播放卡住连续2秒无法播放警告
stopped播放停止用户停止或系统关闭信息

2. 系统资源监控API

FieldStation42提供完整的RESTful API接口监控系统资源:

# 获取系统信息
curl http://localhost:8000/player/info

# 响应示例
{
    "temperature_c": 45.2,
    "temperature_f": 113,
    "temp_source": "vcgencmd",
    "memory": {
        "total_gb": 3.8,
        "available_gb": 2.1,
        "used_gb": 1.7,
        "used_percent": 44.7
    },
    "cpu": {
        "cores": 4,
        "load_1min": 0.8,
        "load_5min": 0.6,
        "load_15min": 0.5,
        "load_percent": 20.0
    },
    "system": {
        "platform": "Linux",
        "architecture": "aarch64",
        "hostname": "raspberrypi"
    }
}
监控指标阈值建议
指标正常范围警告阈值危险阈值恢复建议
CPU温度< 60°C60-70°C> 70°C检查散热
内存使用率< 70%70-85%> 85%清理内存
CPU负载< 80%80-90%> 90%优化进程

3. 播放状态API监控

# 获取当前播放状态
curl http://localhost:8000/player/status

# 检查命令队列连接状态
curl http://localhost:8000/player/status/queue_connected

🚨 告警系统实现方案

方案一:基于Shell脚本的简易监控

#!/bin/bash
# fs42_monitor.sh

STATUS_SOCKET="/tmp/fs42_status.socket"
ALERT_EMAIL="admin@example.com"
MAX_STUCK_TIME=300  # 5分钟

# 监控状态变化
monitor_status() {
    while true; do
        if [[ -f "$STATUS_SOCKET" ]]; then
            status_data=$(cat "$STATUS_SOCKET" 2>/dev/null)
            if [[ -n "$status_data" ]]; then
                status=$(echo "$status_data" | jq -r '.status')
                
                case "$status" in
                    "stuck")
                        echo "ALERT: Player stuck at $(date)"
                        send_alert "Player Stuck" "FieldStation42 player is stuck"
                        ;;
                    "stopped")
                        echo "INFO: Player stopped at $(date)"
                        ;;
                esac
            fi
        fi
        sleep 10
    done
}

# 发送告警
send_alert() {
    subject="$1"
    message="$2"
    echo "$message" | mail -s "$subject" "$ALERT_EMAIL"
}

monitor_status

方案二:Python高级监控服务

# advanced_monitor.py
import json
import time
import requests
import logging
from datetime import datetime, timedelta

class FieldStationMonitor:
    def __init__(self, status_socket, api_url="http://localhost:8000"):
        self.status_socket = status_socket
        self.api_url = api_url
        self.stuck_start_time = None
        self.setup_logging()
    
    def setup_logging(self):
        logging.basicConfig(
            level=logging.INFO,
            format='%(asctime)s - %(levelname)s - %(message)s',
            handlers=[
                logging.FileHandler('/var/log/fs42_monitor.log'),
                logging.StreamHandler()
            ]
        )
    
    def read_status_socket(self):
        try:
            with open(self.status_socket, 'r') as f:
                return json.load(f)
        except (FileNotFoundError, json.JSONDecodeError):
            return None
    
    def check_system_health(self):
        try:
            response = requests.get(f"{self.api_url}/player/info", timeout=5)
            if response.status_code == 200:
                return response.json()
        except requests.RequestException:
            return None
    
    def evaluate_health(self, system_info):
        alerts = []
        
        # CPU温度检查
        if system_info.get('temperature_c', 0) > 70:
            alerts.append(f"CPU温度过高: {system_info['temperature_c']}°C")
        
        # 内存使用检查
        memory = system_info.get('memory', {})
        if memory.get('used_percent', 0) > 85:
            alerts.append(f"内存使用率过高: {memory['used_percent']}%")
        
        # CPU负载检查
        cpu = system_info.get('cpu', {})
        if cpu.get('load_percent', 0) > 90:
            alerts.append(f"CPU负载过高: {cpu['load_percent']}%")
        
        return alerts
    
    def monitor_loop(self):
        while True:
            # 检查播放状态
            status = self.read_status_socket()
            if status and status.get('status') == 'stuck':
                if self.stuck_start_time is None:
                    self.stuck_start_time = datetime.now()
                    logging.warning("播放器卡住检测")
                else:
                    stuck_duration = (datetime.now() - self.stuck_start_time).total_seconds()
                    if stuck_duration > 300:  # 5分钟
                        logging.error("播放器长时间卡住,需要干预")
                        self.trigger_recovery()
            else:
                self.stuck_start_time = None
            
            # 检查系统健康
            system_info = self.check_system_health()
            if system_info:
                alerts = self.evaluate_health(system_info)
                for alert in alerts:
                    logging.warning(alert)
                    self.send_alert(alert)
            
            time.sleep(30)
    
    def trigger_recovery(self):
        try:
            # 尝试重启播放器
            requests.post(f"{self.api_url}/commands/stop", timeout=5)
            logging.info("已发送停止命令,等待系统自动重启")
        except requests.RequestException:
            logging.error("无法连接到API服务器进行恢复")
    
    def send_alert(self, message):
        # 实现告警发送逻辑(邮件、短信、Webhook等)
        print(f"ALERT: {message}")

if __name__ == "__main__":
    monitor = FieldStationMonitor("/tmp/fs42_status.socket")
    monitor.monitor_loop()

方案三:Docker容器化监控

# Dockerfile for FS42 Monitor
FROM python:3.9-slim

WORKDIR /app
COPY requirements.txt .
RUN pip install -r requirements.txt

COPY advanced_monitor.py .
COPY config.yaml .

CMD ["python", "advanced_monitor.py"]
# config.yaml
monitoring:
  status_socket: "/tmp/fs42_status.socket"
  api_url: "http://host.docker.internal:8000"
  check_interval: 30
  alert_thresholds:
    cpu_temp: 70
    memory_usage: 85
    cpu_load: 90
    stuck_time: 300

alerts:
  email:
    enabled: true
    smtp_server: "smtp.example.com"
    smtp_port: 587
    username: "alert@example.com"
    password: "password"
    recipients: ["admin@example.com"]
  
  webhook:
    enabled: true
    url: "https://hooks.slack.com/services/XXX"
  
  sms:
    enabled: false

🛠️ 告警规则配置表

告警类型触发条件严重级别自动恢复动作通知方式
播放卡住status=stuck持续>5min重启播放器邮件+短信
高温告警CPU温度>70°C降低负载/关机邮件+Webhook
内存不足使用率>85%清理缓存邮件
高负载CPU负载>90%调整优先级邮件
API不可用连接超时重试连接日志记录

📈 监控仪表板实现

使用Grafana监控面板

  "dashboard": {
    "title": "FieldStation42 Monitoring",
    "panels": [
      {
        "title": "播放状态",
        "type": "stat",
        "targets": [{
          "expr": "fs42_status{status=\"playing\"}",
          "legendFormat": "正常播放"
        }]
      },
      {
        "title": "系统温度",
        "type": "graph", 
        "targets": [{
          "expr": "fs42_temperature_c",
          "legendFormat": "CPU温度"
        }]
      }
    ]
  }
}

Prometheus监控配置

# prometheus.yml
scrape_configs:
  - job_name: 'fieldstation42'
    static_configs:
      - targets: ['localhost:8000']
    metrics_path: '/player/info'
    params:
      format: ['prometheus']

自动化恢复脚本

#!/bin/bash
# auto_recovery.sh

# 检查播放状态
check_status() {
    local status_file="/tmp/fs42_status.socket"
    if [[ -f "$status_file" ]]; then
        status=$(jq -r '.status' "$status_file" 2>/dev/null)
        if [[ "$status" == "stuck" ]]; then
            # 检查卡住时间
            timestamp=$(jq -r '.timestamp' "$status_file")
            stuck_time=$(date -d "$timestamp" +%s)
            current_time=$(date +%s)
            if (( current_time - stuck_time > 300 )); then
                return 1  # 需要恢复
            fi
        fi
    fi
    return 0  # 状态正常
}

# 执行恢复
perform_recovery() {
    echo "$(date): 执行FieldStation42恢复操作"
    
    # 优雅停止
    curl -X POST http://localhost:8000/commands/stop || true
    sleep 5
    
    # 强制终止残留进程
    pkill -f "python.*field_player" || true
    pkill -f "python.*station_42" || true
    sleep 2
    
    # 重新启动
    cd /path/to/FieldStation42
    nohup python field_player.py >> /var/log/fs42.log 2>&1 &
    
    echo "$(date): 恢复操作完成"
}

# 主监控循环
while true; do
    if ! check_status; then
        perform_recovery
    fi
    sleep 60
done

🎯 最佳实践总结
