Description

Get-AzSubscriptionActivityLog retrieves events from the Activity Log in an Azure subscription using the REST API. Caller identities are translated to their friendly names from their GUIDs. Requires the Az.Accounts module for authentication in the current context.
Note by default, operations with 'List' or 'Get token' in the name are excluded from the results as these can be numerous. To include them, use the -IncludeListAndGetOperations parameter

Permissions

Requires at least a Reader role in the Azure subscription.
Requires Directory.Read.All permission in Microsoft Graph.

Install

Install the script from the PowerShell gallery:
Install-Script Get-AzSubscriptionActivityLog -Force

Connect to Azure

if you haven't already authenticated to Azure, run the Connect-AzAccount cmdlet first, eg
Connect-AzAccount -Subscription "e7b7fedf-90ab-4b0c-913b-a08ccd060d9a"
