Azure Diagnostic Settings

This module is based on work from Innovation Norway.

This Terraform enables the Diagnostic Settings on a given Azure resource.

Note for EventHub usage in destination

If you want to specify an Azure EventHub to send logs and metrics to in logs_destinations_ids, you need to provide a formated string with both the EventHub Namespace authorization send ID and the EventHub name (name of the queue to use in the Namespace) separated by the | character.

Please refer to the example below for a detailed implementation.

Usage

This module is optimized to work with the Claranet terraform-wrapper tool which set some terraform variables in the environment needed by this module. More details about variables set by the terraform-wrapper available in the documentation.

⚠️ Since modules version v8.0.0, we do not maintain/check anymore the compatibility with Hashicorp Terraform. Instead, we recommend to use OpenTofu.

  location            = module.azure_region.location
