基础告警创建
from airflow import DAG from airflow.providers.opsgenie.operators.opsgenie import OpsgenieCreateAlertOperator from datetime import datetime, timedelta default_args = { 'owner': 'airflow', 'depends_on_past': False, 'start_date': datetime(2024, 1, 1), 'retries': 1, 'retry_delay': timedelta(minutes=5), } with DAG('opsgenie_alert_demo', default_args=default_args, schedule_interval='@daily', catchup=False) as dag: create_alert = OpsgenieCreateAlertOperator( task_id='create_opsgenie_alert', opsgenie_conn_id='opsgenie_default', message='数据管道执行失败告警', description='ETL数据处理任务执行失败,请立即检查', priority='P1', # 高优先级 tags=['etl', 'data-pipeline', 'critical'], responders=[ { "name": "数据工程团队", "type": "team" } ], details={ "dag_id": "{{ dag.dag_id }}", "execution_date": "{{ ds }}", "error_message": "{{ ti.xcom_pull(task_ids='process_data') }}" } )智能告警路由与升级
from airflow import DAG from airflow.providers.opsgenie.operators.opsgenie import OpsgenieCreateAlertOperator from airflow.operators.python import PythonOperator from airflow.exceptions import AirflowException def process_data(**context): try: # 数据处理逻辑 if some_condition: raise AirflowException("数据处理异常:数据质量校验失败") except Exception as e: # 根据异常类型设置不同的告警级别和路由 error_type = type(e).__name__ if "Connection" in error_type: priority = "P1" responders = [{"name": "基础设施团队", "type": "team"}] elif "DataQuality" in error_type: priority = "P2" responders = [{"name": "数据质量团队", "type": "team"}] else: priority = "P3" responders = [{"name": "开发团队", "type": "team"}] context['ti'].xcom_push(key='alert_priority', value=priority) context['ti'].xcom_push(key='alert_responders', value=responders) raise with DAG('smart_alert_routing', default_args=default_args) as dag: process_task = PythonOperator( task_id='process_data', python_callable=process_data, provide_context=True ) alert_task = OpsgenieCreateAlertOperator( task_id='send_smart_alert', opsgenie_conn_id='opsgenie_default', message='智能告警:{{ ti.xcom_pull(task_ids="process_data", key="error_type") }}', description='{{ ti.xcom_pull(task_ids="process_data", key="error_message") }}', priority='{{ ti.xcom_pull(task_ids="process_data", key="alert_priority") }}', responders='{{ ti.xcom_pull(task_ids="process_data", key="alert_responders") }}', trigger_rule='one_failed' ) process_task >> alert_task告警关闭自动化
from airflow.providers.opsgenie.operators.opsgenie import OpsgenieCloseAlertOperator def recovery_process(**context): # 恢复逻辑 alert_alias = f"data_alert_{context['ds_nodash']}" context['ti'].xcom_push(key='alert_alias', value=alert_alias) return "恢复完成" with DAG('alert_recovery_workflow', default_args=default_args) as dag: recovery_task = PythonOperator( task_id='execute_recovery', python_callable=recovery_process, provide_context=True ) close_alert_task = OpsgenieCloseAlertOperator( task_id='close_opsgenie_alert', opsgenie_conn_id='opsgenie_default', identifier='{{ ti.xcom_pull(task_ids="execute_recovery", key="alert_alias") }}', identifier_type='alias', note='数据管道已恢复运行,告警关闭', user='airflow-automation' ) recovery_task >> close_alert_task高级路由策略
基于时间的路由
from datetime import datetime def get_time_based_responders(): current_hour = datetime.now().hour if 9 <= current_hour < 18: # 工作时间:路由到值班团队 return [{"name": "Day-Shift", "type": "team"}] elif 18 <= current_hour < 24: # 晚间:路由到on-call工程师 return [{"name": "Night-OnCall", "type": "user"}] else: # 深夜:升级到管理团队 return [ {"name": "Emergency-Response", "type": "team"}, {"name": "Manager-OnDuty", "type": "user"} ]多级升级策略
监控与治理
告警指标收集
from airflow import DAG from airflow.operators.python import PythonOperator from airflow.providers.opsgenie.operators.opsgenie import OpsgenieCreateAlertOperator from prometheus_client import Counter, Gauge # 定义监控指标 ALERT_COUNTER = Counter('airflow_opsgenie_alerts_total', 'Total OpsGenie alerts sent', ['priority', 'team']) ALERT_DURATION = Gauge('airflow_alert_resolution_seconds', 'Time to resolve alerts') def track_alert_metrics(priority, team, duration=None): ALERT_COUNTER.labels(priority=priority, team=team).inc() if duration: ALERT_DURATION.set(duration) with DAG('alert_monitoring_dag', default_args=default_args) as dag: monitor_task = PythonOperator( task_id='monitor_alert_metrics', python_callable=track_alert_metrics, op_args=['P2', 'data-team', 3600] )告警治理看板
| 指标 | 目标值 | 实际值 | 状态 |
|---|---|---|---|
| 平均响应时间 | < 15分钟 | 12分钟 | ✅ |
| 告警解决率 | > 95% | 97% | ✅ |
| 误报警比例 | < 5% | 3% | ✅ |
| 升级事件数 | < 10/月 | 8 | ✅ |
最佳实践
1. 告警模板标准化
def create_standard_alert_template(alert_type, context): templates = { 'data_quality': { 'message': '数据质量告警: {{ dag_id }}', 'priority': 'P2', 'tags': ['data-quality', 'automated'] }, 'infrastructure': { 'message': '基础设施告警: {{ resource }}', 'priority': 'P1', 'tags': ['infra', 'critical'] }, 'performance': { 'message': '性能告警: {{ metric }}阈值超出', 'priority': 'P3', 'tags': ['performance', 'monitoring'] } } template = templates.get(alert_type, templates['performance']) return { **template, 'description': context.get('description', ''), 'details': context.get('details', {}) }2. 告警抑制机制
from airflow.providers.opsgenie.hooks.opsgenie import OpsgenieAlertHook def should_suppress_alert(alert_key, time_window_minutes=30): hook = OpsgenieAlertHook('opsgenie_default') recent_alerts = hook.get_conn().list_alerts( query=f'alias:"{alert_key}" AND createdAt > {get_timestamp(time_window_minutes)}' ) return len(recent_alerts) > 03. 自动化根本原因分析
def perform_rca(alert_context): # 分析告警根本原因 analysis_results = { 'root_cause': identify_root_cause(alert_context), 'impact_assessment': assess_impact(alert_context), 'recommended_actions': generate_recommendations(alert_context) } # 更新告警详情 update_alert_details(alert_context['alert_id'], analysis_results) return analysis_results故障排除
常见问题及解决方案
| 问题现象 | 可能原因 | 解决方案 |
|---|---|---|
| 告警发送失败 | API密钥无效 | 检查OpsGenie连接配置 |
| 响应团队未通知 | 路由配置错误 | 验证团队名称和类型 |
| 告警重复发送 | 缺乏抑制机制 | 实现告警去重逻辑 |
| 升级策略不生效 | 优先级设置错误 | 检查优先级映射关系 |
调试技巧
# 启用详细日志 import logging logging.basicConfig(level=logging.DEBUG) # 测试连接 hook = OpsgenieAlertHook('opsgenie_default') try: response = hook.get_conn().get_alert(alert_id='test') print(f"连接测试成功: {response}") except Exception as e: print(f"连接测试失败: {e}")总结
