Hi there,

I want to create an alert for "SNAT Port Exhaustion" for 3rd party tool to show it in Azure App service, but there is no such option or query allow me to do it, Meanwhile, I can see SNAT port usage chart under Diagnose and solve problems --> Availability and Performance --> SNAT Port Exhaustion.

How Can I create corresponding Alert?

    Jesse Bai Thanks for reaching here! SNAT Port Usage by the instances are not currently available as a metric, hence it would not be possible to configure an alert for SNAT Port Exhaustion.  

    Its recommend to follow the best practices to ensure that SNAT Port Usage is within the safe limits.

    For more detailed information regarding SNAT in App service, please refer to the following article: SNAT with App Service |
