  • 自动化任务调度
  • 任务执行状态跟踪
  • 分布式任务管理
  • 实时进度监控

环境准备

安装与配置

# 使用Docker快速部署
docker run -d --name openclaw \
  -p 8080:8080 \
  -e REDIS_HOST=redis-server \
  openclaw/openclaw:latest
# 或从源码安装
git clone https://github.com/openclaw/openclaw
cd openclaw
pip install -r requirements.txt
python setup.py install

基本配置

# config.yaml
server:
  host: 0.0.0.0
  port: 8080
  debug: false
redis:
  host: localhost
  port: 6379
  db: 0
storage:
  type: mysql
  host: localhost
  database: openclaw

任务定义与提交

创建任务

from openclaw.client import OpenClawClient
client = OpenClawClient("http://localhost:8080")
# 定义任务
task = {
    "name": "data_processing_task",
    "command": "python process_data.py",
    "arguments": {"input": "/data/input.csv", "output": "/data/output.csv"},
    "priority": "high",
    "max_retries": 3,
    "timeout": 3600  # 秒
}
# 提交任务
task_id = client.submit_task(task)
print(f"任务ID: {task_id}")

批量任务

tasks = []
for i in range(10):
    tasks.append({
        "name": f"batch_task_{i}",
        "command": "python batch_job.py",
        "arguments": {"index": i}
    })
task_ids = client.submit_batch(tasks)

进度监控方法

Web 控制台监控

  • 访问 http://localhost:8080
  • 主要功能区域:
    • 仪表盘:全局任务统计
    • 任务列表:所有任务状态
    • 实时日志:任务执行日志
    • 性能图表:CPU/内存使用率

API 监控接口

# 获取任务状态
status = client.get_task_status(task_id)
print(f"状态: {status['state']}")
print(f"进度: {status['progress']}%")
print(f"开始时间: {status['start_time']}")
print(f"运行时长: {status['duration']}")
# 获取任务列表
tasks = client.list_tasks(
    state="running",  # 过滤条件:running, pending, completed, failed
    limit=50,
    offset=0
)
# 实时进度订阅
def progress_callback(progress_data):
    print(f"进度更新: {progress_data}")
client.subscribe_progress(task_id, progress_callback)

CLI 命令行监控

# 查看任务状态
openclaw task status <task_id>
# 查看任务列表
openclaw task list --state running
# 查看任务日志
openclaw task logs <task_id> --tail 100
# 实时监控
openclaw task watch <task_id>

自定义监控脚本

import time
from openclaw.client import OpenClawClient
class TaskMonitor:
    def __init__(self, api_url):
        self.client = OpenClawClient(api_url)
    def monitor_task(self, task_id, interval=5):
        """监控指定任务进度"""
        while True:
            status = self.client.get_task_status(task_id)
            # 打印进度条
            self.print_progress_bar(
                status['progress'],
                status['name'],
                status['state']
            )
            # 检查任务是否完成
            if status['state'] in ['completed', 'failed', 'cancelled']:
                print(f"\n任务 {status['state']}!")
                break
            time.sleep(interval)
    def print_progress_bar(self, progress, name, state):
        """打印进度条"""
        bar_length = 50
        filled_length = int(bar_length * progress / 100)
        bar = '█' * filled_length + '░' * (bar_length - filled_length)
        print(f'\r{name} [{bar}] {progress:.1f}% | {state}', end='')
    def alert_on_completion(self, task_id, email):
        """任务完成时发送通知"""
        status = self.client.wait_for_completion(task_id)
        if status['state'] == 'completed':
            self.send_email(
                email,
                f"任务完成通知: {status['name']}",
                f"任务ID: {task_id}\n完成时间: {status['end_time']}"
            )
# 使用监控器
monitor = TaskMonitor("http://localhost:8080")
monitor.monitor_task("task-123")

Prometheus 集成

# OpenClaw Prometheus配置
metrics:
  enabled: true
  port: 9091
  path: /metrics
# 示例监控指标
# openclaw_tasks_total{state="running"}
# openclaw_tasks_duration_seconds
# openclaw_tasks_retries_total

告警配置

# alerts.yaml
alerts:
  - name: "task_timeout"
    condition: "duration > timeout * 1.2"
    actions:
      - type: "email"
        recipients: ["admin@example.com"]
      - type: "webhook"
        url: "https://hooks.slack.com/services/..."
  - name: "high_failure_rate"
    condition: "failed_tasks / total_tasks > 0.1"
    actions:
      - type: "sms"
        phone: "+1234567890"

最佳实践

监控策略建议

  • 关键任务:设置更短的监控间隔(1-5秒)
  • 批量任务:使用聚合监控,关注整体进度
  • 长时任务:设置检查点和进度保存
  • 依赖任务:监控任务依赖关系图

性能优化

# 使用批量查询减少API调用
def monitor_multiple_tasks(task_ids):
    """批量监控多个任务"""
    statuses = client.batch_get_status(task_ids)
    # 使用异步IO提高效率
    import asyncio
    async def async_monitor():
        tasks = [asyncio.create_task(get_status_async(tid)) for tid in task_ids]
        await asyncio.gather(*tasks)

故障处理

class ResilientMonitor:
    def __init__(self, client):
        self.client = client
        self.retry_count = 0
    def safe_monitor(self, task_id):
        """带重试的监控"""
        try:
            return self.monitor_task(task_id)
        except ConnectionError:
            self.retry_count += 1
            if self.retry_count < 3:
                time.sleep(5)
                return self.safe_monitor(task_id)
            else:
                raise

常见问题排查

任务状态异常

# 查看详细错误信息
openclaw task debug <task_id>
# 检查Worker日志
docker logs openclaw-worker-1
# 验证Redis连接
redis-cli ping

监控数据延迟

  • 检查网络连接
  • 调整WebSocket心跳间隔
  • 增加监控服务资源

内存使用过高

  • 减少历史数据保留时间
  • 调整监控采样频率
  • 使用外部存储(如Redis)缓存数据

扩展与集成

与CI/CD集成

# .gitlab-ci.yml
stages:
  - deploy
  - monitor
monitor_deployment:
  stage: monitor
  script:
    - task_id=$(openclaw submit --name "deploy_${CI_COMMIT_SHA}")
    - openclaw task watch $task_id --timeout 300
  rules:
    - when: on_success

自定义监控插件

# custom_monitor.py
from openclaw.plugins import MonitorPlugin
class CustomMonitor(MonitorPlugin):
    def on_task_start(self, task):
        self.send_slack(f"任务开始: {task['name']}")
    def on_progress_update(self, task, progress):
        if progress == 50:
            self.send_slack("任务过半!")
    def on_task_complete(self, task):
        self.send_slack(f"任务完成: {task['name']}")
# 注册插件
plugin_manager.register(CustomMonitor())

OpenClaw 提供了全面的任务进度监控方案,通过:

  1. 多维度监控:API、CLI、Web控制台
  2. 实时更新:WebSocket推送进度变化
  3. 灵活告警:自定义告警规则和通知方式
  4. 易于扩展:插件系统支持自定义监控逻辑

建议根据具体业务需求选择合适的监控策略,并定期优化监控配置以确保系统高效稳定运行。
