FAQPage Schema
How do I capture crash dumps automatically for a .NET CoreCLR application?▼

To capture crash dumps automatically for a .NET CoreCLR application, you can configure the runtime to generate a dump file upon crashing. This requires identifying the specific platform to select the appropriate collection method like dotnet-dump or procdump.

Can I collect crash dumps from a .NET app running in a Kubernetes container?▼

Yes, you can collect crash dumps from a .NET application running in a Kubernetes container. The dump collection process supports containerized environments, allowing you to automatically generate or manually trigger dumps within Docker and Kubernetes deployments.

How do I trigger an on-demand dump from a running .NET process?▼

To trigger an on-demand dump from a running .NET process, you can use collection tools like dotnet-dump, gcore, or procdump. This manual capture method extracts a dump file from a live process for immediate troubleshooting.

Does dump collection work with NativeAOT applications?▼

Yes, dump collection works with NativeAOT applications. The process configures and collects crash dumps for modern .NET applications, including both CoreCLR and NativeAOT runtimes, by selecting the appropriate method based on the identified runtime environment.

What is the best way to configure .NET crash dumps on Linux?▼

The best way to configure .NET crash dumps on Linux is to identify the CoreCLR or NativeAOT runtime and use compatible tools like dotnet-dump, gcore, or procdump. This ensures the correct automatic collection method is applied for your environment.
