3. Clawdbot监控指标收集

3.1 创建自定义指标导出器

我们需要创建一个专门的指标导出器来收集Clawdbot的性能数据:

# 创建指标导出器目录
mkdir -p /opt/monitoring/clawdbot-exporter
cd /opt/monitoring/clawdbot-exporter

# 创建Python脚本
cat > clawdbot_exporter.py << 'EOF'
#!/usr/bin/env python3

# 配置日志
logging.basicConfig(level=logging.INFO, format='%(asctime)s - %(levelname)s - %(message)s')
logger = logging.getLogger(__name__)

# 定义监控指标
clawdbot_response_time = Histogram('clawdbot_response_time_seconds', 'Clawdbot response time in seconds', ['agent', 'channel'])
clawdbot_requests_total = Counter('clawdbot_requests_total', 'Total number of requests', ['agent', 'channel', 'status'])
clawdbot_active_sessions = Gauge('clawdbot_active_sessions', 'Number of active sessions')
clawdbot_memory_usage = Gauge('clawdbot_memory_usage_bytes', 'Memory usage in bytes')
clawdbot_cpu_usage = Gauge('clawdbot_cpu_usage_percent', 'CPU usage percentage')

# 监控网关状态
gateway_uptime = Gauge('gateway_uptime_seconds', 'Gateway uptime in seconds')
gateway_connected_clients = Gauge('gateway_connected_clients', 'Number of connected clients')

    """获取Clawdbot进程信息"""
    for proc in psutil.process_iter(['pid', 'name', 'cmdline']):
        try:
            if 'clawdbot' in ' '.join(proc.info['cmdline'] or []):
                return proc
        except (psutil.NoSuchProcess, psutil.AccessDenied):
            continue
    return None

    proc = get_clawdbot_process_info()
    if proc:
        try:
            memory_info = proc.memory_info()
            clawdbot_memory_usage.set(memory_info.rss)
            clawdbot_cpu_usage.set(proc.cpu_percent(interval=1))
        except psutil.NoSuchProcess:
            logger.warning("Clawdbot process not found")
    else:
        logger.warning("Clawdbot process not found")

def parse_logs_for_metrics():
    """解析日志文件获取性能指标"""
    log_file = '/tmp/clawdbot-gateway.log'
    if not os.path.exists(log_file):
        return
    
    # 模拟日志解析,实际应根据日志格式调整
    try:
        with open(log_file, 'r') as f:
            lines = f.readlines()[-100:]  # 读取最后100行
        
        for line in lines:
            if 'response_time' in line:
                # 解析响应时间
                pass
            elif 'session_start' in line:
                clawdbot_active_sessions.inc()
            elif 'session_end' in line:
                clawdbot_active_sessions.dec()
    except Exception as e:
        logger.error(f"Error parsing logs: {e}")

def collect_metrics():
    """收集所有指标"""
    collect_system_metrics()
    parse_logs_for_metrics()
    
    # 模拟一些测试数据
    clawdbot_response_time.labels(agent='main', channel='terminal').observe(0.5)
    clawdbot_requests_total.labels(agent='main', channel='terminal', status='success').inc()
    gateway_uptime.set(3600)  # 假设运行1小时
    gateway_connected_clients.set(3)

if __name__ == '__main__':
    # 启动Prometheus指标服务器
    start_http_server(9091)
    logger.info("Clawdbot exporter started on port 9091")
    
    # 定期收集指标
    while True:
        try:
            collect_metrics()
            time.sleep(5)
        except Exception as e:
            logger.error(f"Error collecting metrics: {e}")
            time.sleep(10)

3.2 增强Clawdbot日志输出

为了获得更准确的性能指标,我们需要增强Clawdbot的日志输出:

# 创建日志增强脚本
cat > /root/clawdbot/logs/enhance-logging.js << 'EOF'
const { createWriteStream } = require('fs');
const { spawn } = require('child_process');

// 重写console.log方法,添加时间戳和性能指标
const originalLog = console.log;
console.log = function(...args) {
  const timestamp = new Date().toISOString();
  const message = args.join(' ');
  originalLog.apply(console, [`[${timestamp}]`, ...args]);
  
  // 检测性能相关的日志
  if (message.includes('response_time') || message.includes('duration')) {
    const logStream = createWriteStream('/tmp/clawdbot-performance.log', { flags: 'a' });
    logStream.write(`${timestamp} ${message}\n`);
    logStream.end();
  }
};

// 监控进程性能
setInterval(() => {
  const memoryUsage = process.memoryUsage();
  console.log(`memory_usage rss=${memoryUsage.rss} heapTotal=${memoryUsage.heapTotal} heapUsed=${memoryUsage.heapUsed}`);
}, 30000);
EOF

# 修改启动脚本,启用增强日志
sed -i 's/node dist\/index.js gateway/node -r \/root\/clawdbot\/logs\/enhance-logging.js dist\/index.js gateway/g' /root/start-clawdbot.sh

# 重启服务
bash /root/restart-gateway.sh

      {
        "title": "响应时间分布",
        "type": "histogram",
        "targets": [
          {
            "expr": "histogram_quantile(0.95, sum(rate(clawdbot_response_time_seconds_bucket[5m])) by (le, agent))",
            "legendFormat": "P95 - {{agent}}"
          },
          {
            "expr": "histogram_quantile(0.50, sum(rate(clawdbot_response_time_seconds_bucket[5m])) by (le, agent))",
            "legendFormat": "P50 - {{agent}}"
          }
        ]
      }
    ]
  }
}
4.2.2 吞吐量监控

监控请求量和成功率:

{
  "title": "请求吞吐量",
  "type": "graph",
  "targets": [
    {
      "expr": "sum(rate(clawdbot_requests_total{status='success'}[5m])) by (channel)",
      "legendFormat": "成功 - {{channel}}"
    },
    {
      "expr": "sum(rate(clawdbot_requests_total{status='error'}[5m])) by (channel)",
      "legendFormat": "失败 - {{channel}}"
    }
  ]
}
4.2.3 系统资源监控

监控Clawdbot的资源使用情况:

{
  "title": "系统资源使用",
  "type": "stat",
  "targets": [
    {
      "expr": "clawdbot_memory_usage_bytes / 1024 / 1024",
      "legendFormat": "内存使用 (MB)"
    },
    {
      "expr": "clawdbot_cpu_usage_percent",
      "legendFormat": "CPU使用率 (%)"
    }
  ]
}

4.3 设置告警规则

配置关键指标的告警规则,及时发现问题:

# 在Prometheus配置文件中添加告警规则
cat > /opt/monitoring/prometheus/alerts.yml << 'EOF'
groups:
- name: clawdbot_alerts
  rules:
  - alert: HighResponseTime
    expr: histogram_quantile(0.95, rate(clawdbot_response_time_seconds_bucket[5m])) > 5
    for: 2m
    labels:
      severity: warning
    annotations:
      summary: "高响应时间警报"
      description: "Clawdbot 95%响应时间超过5秒,当前值: {{ $value }}s"

  - alert: HighErrorRate
    expr: rate(clawdbot_requests_total{status="error"}[5m]) / rate(clawdbot_requests_total[5m]) > 0.1
    for: 2m
    labels:
      severity: critical
    annotations:
      summary: "高错误率警报"
      description: "Clawdbot错误率超过10%,当前值: {{ $value }}"

  - alert: HighMemoryUsage
    expr: clawdbot_memory_usage_bytes / (1024 * 1024) > 1024
    for: 5m
    labels:
      severity: warning
    annotations:
      summary: "高内存使用警报"
      description: "Clawdbot内存使用超过1GB,当前值: {{ $value }}MB"
EOF

# 更新Prometheus配置引用告警规则
echo "rule_files:
  - 'alerts.yml'" >> /opt/monitoring/prometheus/prometheus.yml

# 重启Prometheus
systemctl restart prometheus

5. 实战监控与性能分析

5.1 生成测试负载

为了测试监控系统的有效性,我们可以生成一些测试负载:

# 创建性能测试脚本
cat > /root/clawdbot/performance-test.sh << 'EOF'
#!/bin/bash

# 性能测试参数
REQUESTS=${1:-100}
CONCURRENCY=${2:-5}
AGENT="main"

echo "开始性能测试: $REQUESTS 请求, 并发数: $CONCURRENCY"

for i in $(seq 1 $REQUESTS); do
  # 并行发送请求
  for j in $(seq 1 $CONCURRENCY); do
    (
      START_TIME=$(date +%s%N)
      RESPONSE=$(cd /root/clawdbot && node dist/index.js agent --agent $AGENT --message "测试消息 $i-$j" --thinking minimal 2>/dev/null)
      END_TIME=$(date +%s%N)
      DURATION=$((($END_TIME - $START_TIME)/1000000))
      
      echo "请求 $i-$j: $DURATION ms"
    ) &
  done
  wait
  sleep 1
done

echo "性能测试完成"
EOF

chmod +x /root/clawdbot/performance-test.sh

5.2 分析监控数据

运行测试后,在Grafana中观察各项指标的变化:

  1. 响应时间分析:查看P95和P50响应时间是否在可接受范围内
  2. 吞吐量分析:观察每秒处理的请求数量和处理成功率
  3. 资源使用分析:监控CPU和内存使用情况,确认是否存在瓶颈
  4. 错误率分析:检查错误率是否异常升高

5.3 优化建议

根据监控数据,可以给出针对性的优化建议:

# 基于监控结果的优化脚本
cat > /root/clawdbot/optimize-based-on-metrics.sh << 'EOF'
#!/bin/bash

# 获取当前性能指标
RESPONSE_TIME=$(curl -s http://localhost:9090/api/v1/query?query=histogram_quantile\(0.95,rate\(clawdbot_response_time_seconds_bucket\[5m\]\)\) | jq -r '.data.result[0].value[1]')
ERROR_RATE=$(curl -s http://localhost:9090/api/v1/query?query=rate\(clawdbot_requests_total{status=\"error\"}\[5m\]\)/rate\(clawdbot_requests_total\[5m\]\) | jq -r '.data.result[0].value[1]')
MEMORY_USAGE=$(curl -s http://localhost:9090/api/v1/query?query=clawdbot_memory_usage_bytes/1024/1024 | jq -r '.data.result[0].value[1]')

echo "当前性能指标:"
echo "响应时间(P95): ${RESPONSE_TIME}s"
echo "错误率: ${ERROR_RATE}"
echo "内存使用: ${MEMORY_USAGE}MB"

# 根据指标给出优化建议
if (( $(echo "$RESPONSE_TIME > 3" | bc -l) )); then
    echo "建议: 响应时间较高,可以考虑使用更小的模型或优化提示词"
fi

if (( $(echo "$ERROR_RATE > 0.1" | bc -l) )); then
    echo "建议: 错误率较高,请检查模型服务和网络连接"
fi

if (( $(echo "$MEMORY_USAGE > 1024" | bc -l) )); then
    echo "建议: 内存使用较高,可以考虑重启服务或优化配置"
fi
EOF

chmod +x /root/clawdbot/optimize-based-on-metrics.sh
