OpenClaw 简介
OpenClaw 是一个开源的分布式任务调度与监控系统,主要用于:

- 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:
- 多维度监控:API、CLI、Web控制台
- 实时更新:WebSocket推送进度变化
- 灵活告警:自定义告警规则和通知方式
- 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。
