Introduction to New Relic for .NET

With APM for .NET, you can monitor your .NET applications and services. In this introduction to APM for .NET, you'll learn the reasons to use this product, and how to get started using it.

Features

After you install the New Relic .NET agent, you can:

Support for both .NET Framework and .NET Core

New Relic's .NET agent supports both .NET Framework and .NET Core, and it works with all .NET compatible languages, such as VB.NET, C#, and CLI.

The agent's support for .NET Core takes advantage of the compatibility, speed, expanded API features, and cross-platform capabilities of Microsoft's .NET Core. The agent does not support Microsoft .NET Core versions earlier than 2.0.

With New Relic's support for .NET, you can monitor your apps in dynamic or distributed environments, such as:

  • Cloud-managed server VM images
  • On-host VM servers
  • Microsoft Azure App Services
  • Self-hosted Windows and Linux systems
  • Amazon AWS EC2 VMs

Install the agent

Before you install the .NET agent, create your New Relic account. Then, review the requirements for .NET Framework or the requirements for .NET Core.

When you are ready to install, use our launcher or see the install instructions appropriate for your operating system: Windows or Linux.



To stay up-to-date with new features and bug fixes, see the .NET agent release notes.

After you install the agent and wait a few minutes for your app to generate traffic, data will appear in the APM Summary page. If no data appears, or if you encounter other problems, see New Relic's .NET agent troubleshooting procedures.

Configure the agent

The most important part of agent configuration is to give your app a descriptive name. New Relic uses this app name to aggregate metrics when you have multiple apps or hosts. The agent also includes a variety of configuration options to further customize your installation.

Extend your instrumentation

After installing the .NET agent, extend the agent's instrumentation with one or more of these methods:

Instrumentation options Details
Browser instrumentation

Integrate the .NET agent with Browser monitoring to gain visibility into end-user activity.

Custom instrumentation Instrument transactions not captured as part of New Relic's automatic framework instrumentation.
Agent API See the .NET agent API guide to learn how to customize the agent's behavior. For example, you can collect custom metrics, flag an error, or ignore a particular transaction entirely.
Custom attributes Customize the attributes attached to transactions. Customizing attributes allows you to avoid sending sensitive attributes, or to collect additional attributes for deeper visibility into your transactions.
Distributed tracing Enable distributed tracing to understand activity across a complex, distributed system that uses many services and microservices.
Open source telemetry Explore these tools: OpenTelemetry exporter and .NET Telemetry SDK.

Check the source code

The .NET agent is open source software. That means you can browse its source code and send improvements, or create your own fork and build it. For more information, see the README.
