Install Dynatrace Extension On Azure Function & App Service using Terraform

Terraform is a programming language to provision cloud infrastructure (Infrastructure as Code). IaC is all about deploying infrastructure through software. It helps achieve consistent and predictable environments.

The most significant advantage of Terraform is the concept of state files. The state file allows Terraform to deploy the differential. In this way, the provisioning of resources is faster than using other IaC toolsets like ARM or Az Cli.

Dynatrace is a monitoring tool. It provides an in-depth analysis and reporting of the health of enterprise systems.

In this article, I will show how to install the Dynatrace extension via Terraform. Dynatrace is a monitoring tool. It provides an in-depth analysis and reporting of the health of enterprise systems. To enable the monitoring of Azure functions & Azure app service, we can install the Dynatrace extension.

Dynatrace extension on Azure function

We can install the extension from the Azure portal as well. View the link below for detailed steps.

Please note that the below solution will work only for Azure function on Windows.

Step 1 – Create an Azure Resource Group

Step 2 – Create a Storage account

Azure function needs a storage account. It's used for triggers, bindings, and states but there are other usages as well. In case you need detailed information on why Azure function needs a storage account. Read Storage considerations for Azure Functions | Microsoft Learn

Step 3 – Create an App Service Plan(ASP)

An Azure service plan provides the compute for the Azure function.

Step 4 – Create an Azure function

The next step is to create an azure function

We can see a couple of configurations. These are Dynatrace environment-specific configurations to send monitoring information to the Dynatrace server. The configurations are:

• "DT_API_TOKEN"    - PaaS token
• "DT_TENANT"    - Environment ID          

Step 6 – Install DT extension

The last step is to install the DT extension using azapi_resource. azapi_resource does not come as part of azurerm provider. It comes as part of azapi provider. Hence our provider block will look like the below:

The resource block to install the Dynatrace extension is below:

The AzAPI provider is a very thin layer on top of the Azure ARM REST APIs. It complements the AzureRM provider for Azure resources that are not yet supported. If you want to read more on this. See link below:

Dynatrace extension on Azure App Service

In this section, I will cover installation for an Azure App service. We can install the extension from the Azure portal as well. View the link below for detailed steps.

Please note that the below solution will work only for Azure app service on Windows.

Step 1 — Create an Azure Resource Group
