请参阅下面我用来添加诊断设置以将应用服务日志发送到日志分析工作区的配置。

https://registry.terraform.io/providers/hashicorp/azurerm/latest/docs/resources/monitor_diagnostic_setting

    resource "azurerm_app_service" "webapp" {
      for_each = local.apsvc_map_with_locations
    
      name                = "${var.regional_web_rg[each.value.location].name}-${each.value.apsvc_name}-apsvc"
      location            = each.value.location
      resource_group_name = var.regional_web_rg[each.value.location].name
      app_service_plan_id = azurerm_app_service_plan.asp[each.value.location].id
      https_only          = true
           
      identity {
        type         = "UserAssigned"
        identity_ids = each.value.identity_ids
      }
    }
    
    resource "azurerm_monitor_diagnostic_setting" "example" {
      for_each = local.apsvc_map_with_locations
    
      name                       = "example"
      target_resource_id         = "azurerm_app_service.webapp[${each.value.location}-${each.value.apsvc_name}].id"
      log_analytics_workspace_id = data.terraform_remote_state.pod_bootstrap.outputs.pod_log_analytics_workspace.id
      log {
        category = "AuditEvent"
        enabled  = false
    
        retention_policy {
          enabled = false
        }
      }
    
      metric {
        category = "AllMetrics"
    
        retention_policy {
          enabled = false
        }
      }
    }

错误：

Can not parse "target_resource_id" as a resource id: Cannot parse Azure ID: parse "azurerm_app_service.webapp[].id": invalid URI for request

【解决方案1】：

您可以尝试以下方法：

target_resource_id         = azurerm_app_service.webapp["${each.value.location}-${each.value.apsvc_name}"].id

代替：

target_resource_id         = "azurerm_app_service.webapp[${each.value.location}-${each.value.apsvc_name}].id"
