Monitor a web app with web server logs
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 you don't have an Azure subscription, create a free account before you begin.
Launch Azure Cloud Shell
The Azure Cloud Shell is a free Bash shell that you can run directly within the Azure portal. It has the Azure CLI preinstalled and configured to use with your account. Click the Cloud Shell button on the menu in the upper-right of the Azure portal.
The button launches an interactive shell that you can use to run the steps in this topic:
If you choose to install and use the CLI locally, this topic requires that you are running the Azure CLI version 2.0 or later. Run
az --version to find the version. If you need to install or upgrade, see Install Azure CLI 2.0.
