Introduction to New Relic for .NET

New Relic's .NET agent monitors your .NET app, giving you an end-to-end view of your app's performance. Once you install the .NET agent, you can:


New Relic's .NET Framework agent works with all .NET compatible languages, such as VB.NET, C#, and CLI. The .NET Core agent takes advantage of the compatibility, speed, expanded API features, and cross-platform capabilities of Microsoft's .NET Core. The .NET Core agent does not support Microsoft .NET Core versions earlier than 2.0.

With New Relic's .NET Core agent, you can easily 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

The .NET Core agent instruments Microsoft .NET Core processes to monitor apps on both Linux and Windows operating systems, including auto-instrumentation of web and external calls, Kestrel web transactions, and more.

Install the agent

Before you install a .NET agent, create your New Relic account. Then, review the .NET Framework agent system requirements or the .NET Core agent system requirements. When you are ready to install, see the .NET agent install overview.

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 to generate traffic for your app, data will appear in the New Relic APM Overview page. If no data appears, or if you encounter other problems, see New Relic's .NET 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 further. For example:

Instrumentation options Comments
Browser instrumentation

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

Custom instrumentation Instrument transactions not captured as part of New Relic's automatic framework instrumentation.
Agent API Refer to 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.
