Prometheus集成实现
1. 依赖安装
# 使用pip安装Prometheus客户端
pip install prometheus-client
2. 指标定义与埋点(以S2版本为例)
在gui_agents/s2/core/engine.py中添加:
from prometheus_client import Counter, Gauge, Histogram, start_http_server
import time
# 定义指标
TASK_SUCCESS_COUNT = Counter('agent_s_task_success_total', 'Total number of successful tasks', ['task_type', 'agent_version'])
TASK_FAILURE_COUNT = Counter('agent_s_task_failure_total', 'Total number of failed tasks', ['task_type', 'error_type'])
TASK_DURATION = Histogram('agent_s_task_duration_seconds', 'Task execution duration in seconds', ['task_type'])
QUEUE_LENGTH = Gauge('agent_s_queue_length', 'Current task queue length')
MEMORY_USAGE = Gauge('agent_s_memory_usage_bytes', 'Memory usage in bytes')
class AgentSEngine:
def __init__(self, agent_version="s2"):
self.agent_version = agent_version
# 启动metrics HTTP服务
start_http_server(8000)
# 启动内存监控线程
self._start_memory_monitor()
def execute_task(self, task_type, task_func, *args, **kwargs):
QUEUE_LENGTH.inc() # 队列长度+1
start_time = time.time()
try:
result = task_func(*args, **kwargs)
TASK_SUCCESS_COUNT.labels(task_type=task_type, agent_version=self.agent_version).inc()
return result
except Exception as e:
TASK_FAILURE_COUNT.labels(
task_type=task_type,
error_type=type(e).__name__,
agent_version=self.agent_version
).inc()
raise e
finally:
QUEUE_LENGTH.dec() # 队列长度-1
TASK_DURATION.labels(task_type=task_type).observe(time.time() - start_time)
def _start_memory_monitor(self):
import threading
def monitor():
import psutil
process = psutil.Process()
while True:
MEMORY_USAGE.set(process.memory_info().rss)
time.sleep(5)
thread = threading.Thread(target=monitor, daemon=True)
thread.start()
3. Prometheus配置文件
创建prometheus.yml:
global:
scrape_interval: 5s
evaluation_interval: 5s
scrape_configs:
- job_name: 'agent-s'
static_configs:
- targets: ['localhost:8000'] # Agent-S metrics端点
labels:
group: 'local'
- job_name: 'agent-s-cluster'
static_configs:
- targets: [
'agent-s-1:8000',
'agent-s-2:8000',
'agent-s-3:8000'
]
labels:
group: 'production'
4. 启动Prometheus
# 拉取镜像
docker pull prom/prometheus:v2.45.0
# 启动容器
docker run -d \
-p 9090:9090 \
-v $(pwd)/prometheus.yml:/etc/prometheus/prometheus.yml \
--name agent-s-prometheus \
prom/prometheus:v2.45.0
Grafana可视化配置
1. 启动Grafana
docker pull grafana/grafana:10.1.0
docker run -d \
-p 3000:3000 \
--name agent-s-grafana \
grafana/grafana:10.1.0
2. 配置Prometheus数据源
- 访问
http://localhost:3000,默认账号密码admin/admin - 导航到Configuration > Data Sources > Add data source
- 选择Prometheus,URL填写
http://agent-s-prometheus:9090 - 点击Save & Test
3. 业务仪表盘设计(JSON片段)

告警规则配置
1. Prometheus告警规则(alert.rules.yml)
groups:
- name: agent-s-alerts
rules:
- alert: HighErrorRate
expr: sum(rate(agent_s_task_failure_total[5m])) / sum(rate(agent_s_task_success_total[5m]) + rate(agent_s_task_failure_total[5m])) > 0.05
for: 2m
labels:
severity: critical
service: agent-s
annotations:
summary: "高任务失败率告警"
description: "任务失败率超过5% (当前值: {{ $value }})"
runbook_url: "https://gitcode.com/GitHub_Trending/ag/Agent-S/wiki/Alert-Runbook-HighErrorRate"
- alert: LongTaskDuration
expr: histogram_quantile(0.95, sum(rate(agent_s_task_duration_seconds_bucket[5m])) by (le, task_type)) > 60
for: 5m
labels:
severity: warning
service: agent-s
annotations:
summary: "任务执行时间过长"
description: "{{ $labels.task_type }}任务95分位耗时超过60秒 (当前值: {{ $value }})"
- alert: HighQueueLength
expr: max(agent_s_queue_length) > 100
for: 1m
labels:
severity: critical
service: agent-s
annotations:
summary: "任务队列堆积"
description: "任务队列长度超过100 (当前值: {{ $value }})"
2. Alertmanager配置(alertmanager.yml)
global:
resolve_timeout: 5m
route:
group_by: ['alertname', 'service']
group_wait: 10s
group_interval: 10s
repeat_interval: 1h
receiver: 'dingtalk'
receivers:
- name: 'dingtalk'
webhook_configs:
- url: 'http://dingtalk-webhook:8060/dingtalk/webhook1/send'
send_resolved: true
3. 启动Alertmanager
docker run -d \
-p 9093:9093 \
-v $(pwd)/alertmanager.yml:/etc/alertmanager/alertmanager.yml \
-v $(pwd)/alert.rules.yml:/etc/prometheus/alert.rules.yml \
--name agent-s-alertmanager \
prom/alertmanager:v0.25.0
多版本适配指南
S1版本适配
在gui_agents/s1/core/AgentS.py中添加指标暴露:
# S1版本没有独立的Engine类,直接在AgentS主类中添加
def __init__(self):
# 原有初始化代码...
from prometheus_client import start_http_server
start_http_server(8000)
self._init_metrics()
def _init_metrics(self):
self.task_counter = Counter('agent_s_task_total', 'Total tasks processed', ['status', 'task_type'])
def execute_task(self, task):
try:
# 原有任务执行代码...
self.task_counter.labels(status='success', task_type=task.type).inc()
except:
self.task_counter.labels(status='failure', task_type=task.type).inc()
raise
S2.5版本适配
S2.5版本已有模块化设计,可在core/module.py中添加MetricsModule:
class MetricsModule(BaseModule):
def __init__(self, agent):
super().__init__(agent)
self._register_metrics()
self._start_server()
def _register_metrics(self):
self.resource_usage = Gauge('agent_s_resource_usage', 'System resource usage', ['resource_type'])
def _start_server(self):
start_http_server(8000)
def update_metrics(self):
# 定期更新系统资源指标
self.resource_usage.labels(resource_type='cpu').set(self._get_cpu_usage())
self.resource_usage.labels(resource_type='memory').set(self._get_memory_usage())
高级特性:异常检测告警
1. 安装Prometheus Anomaly Detector
git clone https://gitcode.com/GitHub_Trending/ag/Agent-S.git
cd Agent-S/monitoring/anomaly-detector
pip install -r requirements.txt
2. 启动异常检测服务
python detector.py --prometheus-url http://localhost:9090 --alertmanager-url http://localhost:9093
3. 异常检测算法配置
# anomaly_detector/config.py
ALGORITHMS = {
'cpu_usage': {
'type': 'isolation_forest',
'window_size': 300, # 5分钟窗口
'contamination': 0.01, # 异常比例阈值
'sensitivity': 0.85
},
'task_duration': {
'type': 'stl_decomposition',
'seasonal_periods': 360, # 1小时周期
'threshold': 3.0 # 3倍标准差
}
}
部署与运维最佳实践

启动命令:docker-compose up -d
2. 监控系统自监控
| 监控项 | 指标名称 | 告警阈值 | 解决措施 | |
|---|---|---|---|---|
| Prometheus健康状态 | up{job="prometheus"} | == 0 | 重启Prometheus服务 | |
| Grafana可用性 | probe_success{job="grafana"} | == 0 | 检查Grafana容器状态 | |
| 磁盘空间使用率 | node_filesystem_avail_bytes{fstype!~"tmpfs | devtmpfs"} | < 10% | 清理磁盘空间 |
| 内存使用率 | node_memory_MemAvailable_bytes / node_memory_MemTotal_bytes * 100 | < 15% | 增加内存或优化应用 |
