azure - 触发警报时不会触发操作

Question

使用 Terraform 我创建了警报、操作组和 Logicapp。 (代码1如下所示)

触发警报时触发的操作，其中操作类型之一是逻辑应用程序，这符合预期。当条件为真时，会触发警报，进一步触发逻辑应用操作。

后来，我收到调整警报阈值和频率的要求，并对 Terraform 代码进行了更改，在执行计划/应用时仅注意到警报频率和阈值的变化，这些都是预期的。 (代码2如下所示)

在此更改(更新)警报属性操作后，该操作已停止运行。当警报被触发时，操作不会被触发。

测试 1:检查天气警报本身是否真正触发

• 只是为了测试警报本身是否被触发的功能，我订阅了通知类型以将邮件发送到我的收件箱。这有效，我收到了有关警报的邮件，但警报无法触发操作。

测试 1.2:门户的更改

• 我从 Azure 门户中删除了操作类型下的testing-logicapp(逻辑应用操作)。

• 并在Azure 门户的操作类型下添加了testing-logicapp(逻辑应用操作)。 (如下图JPG-3)

• 这会导致在触发警报时触发操作。

所以，我的疑问是，我应该如何以 terraform 方式处理这种情况。

Answer 1

在 Microsoft 支持团队的帮助下发现了该问题。创建了新的 azurerm_logic_app_trigger_http_request 流。

resource "azurerm_logic_app_trigger_http_request" "logic_app_httptrigger_code" {
  name         = "alertv2httPayload"
  logic_app_id = azurerm_logic_app_workflow.myvm_task_logicapp.id

  schema = data.local_file.httptrigger_code.content
} 

您需要在actiongroup下的Logic_app_receiver中使用azurerm_logic_app_trigger_http_request的callbackurl:

azurerm_logic_app_trigger_http_request.logic_app_httptrigger_code.callback_url

而不是

azurerm_logic_app_workflow.myvm_task_logicapp.access_endpoint
