Automatic discovery for back-end applications in Windows 🔗

Automatic discovery can detect the following types of applications in your Windows environment:

Automatic discovery and configuration for OpenTelemetry .NET activates automatic instrumentation for .NET applications running on Windows. After installing the package, you must start or restart any .NET applications that you want to instrument.

Note

The SignalFx instrumentation for .NET is deprecated and will reach end of support on February 21, 2025. To learn how to migrate from SignalFx .NET to OpenTelemetry .NET, see Migrate from the SignalFx .NET Instrumentation.

Get started 🔗

To get started with automatic discovery for Windows, follow these steps:

  1. Install the package

  2. Configure the .NET instrumentation

  3. (Optional) Upgrade the package

Install the package 🔗

By default, the installer script only installs the Collector. If you add the with_dotnet_instrumentation parameter, the script also downloads and installs the Splunk Distribution of OpenTelemetry .NET.

Run the PowerShell script with the with_dotnet_instrumentation parameter, as shown in the following example:

& {Set-ExecutionPolicy Bypass -Scope Process -Force; `
$script = ((New-Object System.Net.WebClient).DownloadString('https://dl.signalfx.com/splunk-otel-collector.ps1')); `
$params = @{access_token = "<access_token>"; realm = "<realm>"; mode = "agent"; with_dotnet_instrumentation = "`$true"; deployment_env = "<environment_name>"}; `
Invoke-Command -ScriptBlock ([scriptblock]::Create(". {$script} $(&{$args} @params)"))}

Do the following to customize the command:

  • Replace <environment_name> with the label for the target environment.

  • Replace <access_token> with a valid Splunk Observability Cloud access token. To obtain an access token, see Retrieve and manage user API access tokens using Splunk Observability Cloud.

  • Replace <realm> is the Splunk Observability Cloud realm, for example, us0. To find the realm name of your account, open the navigation menu in Splunk Observability Cloud, select Settings, and then select your username. The realm name appears in the Organizations section.

Configure the .NET instrumentation 🔗

To configure the instrumentation, see Configure the Splunk Distribution of OpenTelemetry .NET.

(Optional) Upgrade the package 🔗

You can upgrade the package by installing a new version of the Splunk Distribution of OpenTelemetry .NET. See Instrument your .NET application for Splunk Observability Cloud (OpenTelemetry).
