Is it possible to check scale up logs

I've an azure app service, then i want to know when someone scaleup or scales down my service plan i want to know who did that.

I've used the below command but didnt get any logs

az monitor activity-log list --resource-group YourRGName subscriptions/subscription-id/resourceGroups/YourRGName/providers/Microsoft.Web/serverfarms/AppServicePlan --query "[?operationName.value=='Microsoft.Web/serverfarms/write']"

can please someone help me out.

The reason you're not getting the logs is because, the CLI command is missing the --resource-id flag before specifying the resource path.

Use the below command to get the logs without any issues.

az monitor activity-log list --resource-group <resource-group-name> --resource-id /subscriptions/subscription-id/resourceGroups/<resource-group-name>/providers/Microsoft.Web/serverfarms/AppServicePlan --query "[?operationName.value=='Microsoft.Web/serverfarms/write']"

Please refer this Msdoc for Azure CLI command. You can see the logs now.

• LocalizedValue indicates the specific changes made to the Azure App Service Plan.
• Caller shows the username of the individual who performed the scale-up or scale-down action.

You can also view the logs in your Azure app service

Go to App service - > Monitoring -> Diagnostic settings -> follow the below steps

In the activity log of your App Service Plan, you can see who scaled it up or down.
