【Azure Developer】使用 Azure Python 查看 Azure 所有的 Alert rule

问题描述

在Azure Alert 门户中，可以列举出所有Azure资源的Alert rule信息，如下图：

如果像通过Python SDK来获取所有的Alert Rule，有什么可以参考的代码吗？

 

问题分析

由于Azure Alert门户是把所有的资源中配置了Alert Rule都进行了汇总显示，而SDK中并没有一个方法客户获取到所有Azure资源的Alert。所以需要先知道需要什么资源的Alert，然后再Github Python的开源代码库中寻找正确的Package 和 方法。

 

1) 可以在Alert Rule页面中发现需要查看Rule的Type，页面上可以过滤的值有： Metrics，Activity Log， Application Insights， Log ... 

 

2) Clone azure-sdk-for-python （https://github.com/Azure/azure-sdk-for-python/tree/azure-monitor-query_1.0.1/sdk/monitor/azure-monitor-query/samples）并在Source中查看对应Provider的示例代码

  

3）编写自己的Python 代码，如下的示例中，包含了获取获取Classic， Log Search， Activity 和 Metrics的Alert Rule信息。

from azure.mgmt.monitor import MonitorManagementClient
from azure.identity import DefaultAzureCredential
from msrestazure.azure_cloud import AZURE_CHINA_CLOUD as CLOUD
import os


os.environ["SUBSCRIPTION_ID"] = "xxxxxxyour-subidxxxxxx"
os.environ["AZURE_TENANT_ID"] = "your tenant idxxxxx"
os.environ["AZURE_CLIENT_ID"]  = "client_id_sp"
os.environ["AZURE_CLIENT_SECRET"]  = "pw_sp"

subscription_id = os.environ["SUBSCRIPTION_ID"]
credential = DefaultAzureCredential(authority=CLOUD.endpoints.active_directory)

# create client
client1 = MonitorManagementClient(
    credential,
    subscription_id,
    base_url=CLOUD.endpoints.resource_manager,
    credential_scopes=[CLOUD.endpoints.resource_manager + "/.default"]
)

#classic
my_alerts1 = client1.alert_rules.list_by_subscription()

for j in my_alerts1:
    print(j)

#log search alerts
client2 = MonitorManagementClient(
    credential,
    subscription_id,
    base_url=CLOUD.endpoints.resource_manager,
    credential_scopes=[CLOUD.endpoints.resource_manager + "/.default"]
)
my_alerts2 = client2.scheduled_query_rules.list_by_subscription()
for j in my_alerts2:
    print(j)

#activity alerts
client3 = MonitorManagementClient(
    credential,
    subscription_id,
    base_url=CLOUD.endpoints.resource_manager,
    credential_scopes=[CLOUD.endpoints.resource_manager + "/.default"],
    api_version="2017-04-01"
)

my_alerts3 = client3.activity_log_alerts.list_by_subscription_id()
for j in my_alerts3:
    print(j)

#metric alerts
client4 = MonitorManagementClient(
    credential,
    subscription_id,
    base_url=CLOUD.endpoints.resource_manager,
    credential_scopes=[CLOUD.endpoints.resource_manager + "/.default"]
)

my_alerts4 = client4.metric_alerts.list_by_subscription()
for j in my_alerts4:
    print(j)
