Dump

The Steeltoe thread dump endpoint can be used to generate a snapshot of information about all the threads in your application. That snapshot includes several bits of information for each thread, including the thread's state, a stack trace, any monitor locks held by the thread, any monitor locks the thread is waiting on, and other details.

NOTE: At this time, thread dumps are only possible on the Windows operating system. When integrating with the TAS Apps Manager, you will not have the ability to obtain thread dumps from apps running on Linux cells.

Configure Settings

The following table describes the settings that you can apply to the endpoint:

Key	Description	Default
id	The ID of the thread dump endpoint	dump
enabled	Whether to enable the thread dump management endpoint	true
sensitive	Currently not used	false

Note: Each setting above must be prefixed with management:endpoints:dump.

Enable HTTP Access

The default path to the Thread Dump endpoint is computed by combining the global path prefix setting together with the id setting from above. The default path is /actuator/dump.

The coding steps you take to enable HTTP access to the Thread Dump endpoint differs depending on the type of .NET application your are developing. The sections which follow describe the steps needed for each of the supported application types.

ASP.NET Core App

To add the Thread dump actuator to the service container, use the AddThreadDumpActuator() extension method from EndpointServiceCollectionExtensions.

To add the Thread dump actuator middleware to the ASP.NET Core pipeline, use the UseThreadDumpActuator() extension method from EndpointApplicationBuilderExtensions.

ASP.NET 4.x App

To add the Thread Dump actuator endpoint, use the UseThreadDumpActuator() method from ActuatorConfigurator.

ASP.NET OWIN App

To add the Thread Dump actuator middleware to the ASP.NET OWIN pipeline, use the UseThreadDumpActuator() extension method from ThreadDumpEndpointAppBuilderExtensions.
