DumbMonit 监控的内容
The health of an Azure subscription: resources that Azure reports as unavailable or degraded, and the Azure Monitor alerts that are fired and not closed. DumbMonit reads two lists on management.azure.com, once a minute: Resource Health (Microsoft.ResourceHealth/availabilityStatuses, API 2022-10-01), the availability that the Azure platform announces for each resource, and the Azure Monitor alerts (Microsoft.AlertsManagement/alerts, API 2019-05-05-preview) that are fired and either new or acknowledged.

设置步骤: Create a read-only application for DumbMonit
In the Azure portal, open Microsoft Entra ID > App registrations > New registration, name it DumbMonit, keep single tenant, then Register.
On the Overview page, copy the Application (client) ID and the Directory (tenant) ID.
Open Certificates & secrets > New client secret, choose a lifetime, then copy the secret Value: it is shown once.
Open Subscriptions > your subscription > Access control (IAM) > Add > Add role assignment, pick the Reader role, select the DumbMonit application, then Review + assign.
Copy the Subscription ID from the subscription Overview page.
In DumbMonit, enter management.azure.com as address, paste the client ID and secret, and fill the Tenant ID and Subscription ID options.
注意. A stopped or deallocated virtual machine is reported by Azure as unavailable on the user's request: it is counted apart and raises no alert. Azure Monitor alerts need the Microsoft.AlertsManagement resource provider registered on the subscription; without it only Resource Health is monitored.
