LangfuseServiceCollectionExtensions

NexusLabs.Needlr.AgentFramework.Langfuse ¶

LangfuseServiceCollectionExtensions Class¶

Registers Langfuse OTLP export on an Microsoft.Extensions.DependencyInjection.IServiceCollection for ASP.NET Core and generic-host applications.

public static class LangfuseServiceCollectionExtensions

Inheritance System.Object 🡒 LangfuseServiceCollectionExtensions

Remarks¶

Unlike Start(LangfuseOptions) — which builds standalone providers for evals and console apps — this integrates with the host's AddOpenTelemetry() pipeline so the tracer and meter providers share the application lifecycle. When the supplied options are not configured (for example, missing credentials), registration is skipped and the application starts normally without exporting.

Methods¶

LangfuseServiceCollectionExtensions.AddNeedlrLangfuse(this IServiceCollection, Action<LangfuseOptions>) Method¶

Adds Langfuse OTLP/HTTP export of Needlr agent telemetry to the host's OpenTelemetry pipeline.

public static Microsoft.Extensions.DependencyInjection.IServiceCollection AddNeedlrLangfuse(this Microsoft.Extensions.DependencyInjection.IServiceCollection services, System.Action<NexusLabs.Needlr.AgentFramework.Langfuse.LangfuseOptions>? configure=null);
