Mark Downie is a program manager on the Visual Studio Production Diagnostics team. He blogs about how you can use Visual Studio to get to the bottom of gnarly issues in production.
Snapshot Debugger is built for production so you can set Snappoints and Logpoints in code, like debugger breakpoints and tracepoints. However, when a Snappoint is hit in an AKS Linux Docker container, a snapshot is dynamically created without stopping the process. You are then able to attach to these snapshots using Visual Studio.
The Time Travel Debugging (TTD) preview in Visual Studio Enterprise 2019 provides the ability to record a Web app running on a Azure Virtual Machine (VM) and then accurately reconstruct and replay the execution path. TTD integrates with our Snapshot Debugger offering and allows you to rewind and replay each line of code however many times you want, helping you isolate and identify problems that might only occur in production environments.
We are excited to announce that in Visual Studio Enterprise 2019 we are expanding Snapshot Debugger support beyond Azure App Services hosting ASP.NET Core and ASP.NET applications to also include Azure Virtual Machines (VM), Azure Virtual Machine scale sets (VMSS) and Azure Kubernetes Services (AKS).
