Monitor a web app with web server logs

  • Artikkeli

In this scenario you will create a resource group, app service plan, web app and configure the web app to enable web server logs. You will then download the log files for review.

If needed, install the Azure PowerShell using the instruction found in the Azure PowerShell guide, and then run Connect-AzAccount to create a connection with Azure.

Sample script

Note

We recommend that you use the Azure Az PowerShell module to interact with Azure. To get started, see Install Azure PowerShell. To learn how to migrate to the Az PowerShell module, see Migrate Azure PowerShell from AzureRM to Az.
