Microsoft Azure Developer Associate AZ-204 Practice Question
Your production Web App runs on Azure App Service for Windows in the Premium V2 tier. During spikes in traffic, requests occasionally time out. You suspect a thread-pool deadlock and need a full memory and thread dump for offline analysis, but you must avoid recycling the worker process to meet the SLA. Which built-in App Service feature lets you capture the dump directly from the Azure portal without restarting the app?
Diagnose and solve problems - Collect Memory Dump tool
The Diagnose and solve problems blade in the Azure portal includes the Collect Memory Dump tool. This feature captures a full memory and thread dump of the running worker process while the site continues to serve traffic, so no application restart is required. Kudu's WebSSH console can browse the file system and run commands but cannot create process dumps. Log Stream only streams existing logs and error messages; it does not take memory snapshots. Application Insights Profiler records CPU and execution traces, not complete memory dumps needed to inspect thread states.
