Splunk OpenTelemetry Zero Configuration Auto Instrumentation for .NET 🔗

Splunk OpenTelemetry Zero Configuration Auto Instrumentation for .NET provides a package that automatically instruments your local ASP.NET applications to capture and report distributed traces to the Splunk Distribution of OpenTelemetry Collector, and then on to Splunk APM.

The Zero Configuration package provides the following benefits:

  • You can start streaming traces and monitor distributed applications with Splunk APM in minutes.

  • You don’t need to configure or instrument your .NET back-end services or applications before deployment.

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 SignalFx Instrumentation for .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 SignalFx Instrumentation for .NET.

Upgrade the package 🔗
