Update incorrect statement about webapp restart when adding diagnostic settings. The event is actually akin to a web recycle and is zero downtime. A restart would be an outage. A recycle is not an outage. This should be clear. We have tested this to be the case on a Linux Container Based WebApp.

Pull request overview

Note

Copilot was unable to run its full agentic suite in this review.

Updates App Service diagnostics documentation to clarify that adding Azure Monitor diagnostic settings triggers an application recycle (not a full restart/outage), aligning the wording with observed behavior.

Changes:

  • Replaced “app restart” wording with “zero downtime application recycle” language
  • Added a reference to the UpdateWebSite event in the Activity log as supporting detail

💡 Add Copilot custom instructions for smarter, more guided reviews. Learn how to get started.

## Send logs to Azure Monitor

With [Azure Monitor integration](https://aka.ms/appsvcblog-azmon), you can [create diagnostic settings](https://azure.github.io/AppService/2019/11/01/App-Service-Integration-with-Azure-Monitor.html#create-a-diagnostic-setting) to send logs to storage accounts, event hubs, and Log Analytics workspaces. When you add a diagnostic setting, App Service adds app settings to your app, which triggers an app restart.
