.NET agent v8.25.214.0

New Features

• Thread profiling support for Linux

  Thread profiling on Linux will be supported on .NET Core 3.0 or later applications when running .NET agent version 8.23 or later. Triggering a thread profile is done from the Thread profiler page in APM.

• Accessing Span-Specific information using the .NET Agent API

  New property, CurrentSpan has been added to IAgent and ITransaction. It returns an object implementing ISpan which provides access to span-specific functions within the API.

• Adding Custom Span Attributes using the .NET Agent API

  New method, AddCustomAttribute(string, object) has been added to ISpan.

  • This new method accepts and supports all data-types.
  • Further information may be found within .NET Agent API documentation.
  • Adding custom attributes to spans requires distributed tracing and span events to be enabled. See .NET agent configuration

Fixes

• Fixes issue where adding multiple custom attributes on a Transaction using ITransaction.AddCustomAttribute causes the agent to ignore additional attempts to add custom attributes to any transaction.
• Fixes issue that prevented Custom Events from being sent to New Relic until the agent shuts down.
• Fixes issue that can cause asynchronous Redis calls in an ASP.NET MVC application to report an inflated duration.

• Follow standard procedures to update the .NET agent.
