Pattern: Disabled failed request tracing for Azure App Service

Issue: -

Description

Detailed tracing information on failed requests, including a trace of the IIS components used to process the request and the time taken in each component. It's useful if you want to improve site performance or isolate a specific HTTP error. One folder is generated for each failed request, which contains the XML log file, and the XSL stylesheet to view the log file with.

Resolution: enable failed_request_tracing_enabled.

Examples

Example of incorrect code:

resource "azurerm_app_service" "bad_example" {
  name                = "example-app-service"
  location            = azurerm_resource_group.example.location
  resource_group_name = azurerm_resource_group.example.name
  app_service_plan_id = azurerm_app_service_plan.example.id
}

Example of correct code:

resource "azurerm_app_service" "good_example" {
  name                = "example-app-service"
  location            = azurerm_resource_group.example.location
  resource_group_name = azurerm_resource_group.example.name
  app_service_plan_id = azurerm_app_service_plan.example.id

  logs {
    failed_request_tracing_enabled = true
  }
