This post will show you how to get the ARM (also for Bicep, Terraform, etc) names of the diagnostics logs for an Azure resource.
Problem
When you are deploying Azure resources as code, you might need to enable diagnostics logs. This might require you to know the name of each log. Here’s the issue: the names of the logs in the Azure Portal are usually different from the names that are used in the code. Sure, they’ll remove the spaces and use camel-case, but that’s predictable. Often, the logs have completely different names.
Sometimes the names are documented – thank you App Services! Sometimes you cannot find the log names – boo Azure SQL!
Solution
The tip that I’m going to share is useful – this is the second time in a few weeks that I’ve used this approach.
If you know what you are looking for, diagnostics logs in this case, then do a search online for something like “Azure Diagnostics Settings REST API”. This will bring you to a Microsoft page that shares different methods for the API.
I wanted to see what the log names are for an Azure SQL Database. So I manually created the diagnostic setting. After that, grab the resource ID of the Azure SQL Database.
Then I did the above search. I clicked the Get method and then clicked the Try It button. Put the name of the diagnostic setting (that you created) in name. Put the resource ID of the Azure SQL Database in resourceID. And then click Run. A second later, the ARM for the diagnostic setting is presented on a screen below, including all the diagnostics log names.
