ANcpSdk.AspNetCore.ServiceDefaults

Runtime library for ASP.NET Core service defaults and OpenTelemetry instrumentation.

Overview

Provides:

  • Service defaults configuration - OpenTelemetry, health checks, resilience
  • Instrumentation runtime - Activity wrappers for GenAI and database calls
  • [OTel] attribute - Marker for compile-time tag generation

Architecture

Instrumentation/
├── ActivitySources.cs       ← Centralized ActivitySource definitions
├── SemanticConventions.cs   ← OTel semantic convention constants
├── OTelAttribute.cs         ← [OTel] marker attribute
├── GenAi/
│   ├── GenAiInstrumentation.cs ← Execute/ExecuteAsync wrappers
│   └── TokenUsage.cs           ← Token count record
└── Db/
    └── DbInstrumentation.cs    ← DbCommand wrappers

Instrumentation

GenAI

Wraps AI SDK calls with OpenTelemetry spans:

// Called by generated interceptors
GenAiInstrumentation.ExecuteAsync(
    provider: "openai",
    operation: "chat",
    model: "gpt-4",
    execute: () => client.CompleteChatAsync(messages),
    extractUsage: r => new TokenUsage(r.Usage.InputTokenCount, r.Usage.OutputTokenCount));

Emits spans with:

  • gen_ai.system - Provider name
  • gen_ai.operation.name - Operation type
  • gen_ai.request.model - Model name
  • gen_ai.usage.input_tokens - Input token count
  • gen_ai.usage.output_tokens - Output token count

Database

Wraps DbCommand methods with OpenTelemetry spans:

// Called by generated interceptors
DbInstrumentation.ExecuteReaderAsync(command, cancellationToken);

Emits spans with:

  • db.system.name - Database system (postgresql, mysql, etc.)
  • db.operation.name - Operation type (ExecuteReader, ExecuteNonQuery, etc.)
  • db.query.text - SQL command text
  • db.namespace - Database name

[OTel] Attribute

Mark properties for automatic tag generation:

using ANcpSdk.AspNetCore.ServiceDefaults.Instrumentation;

public record ChatRequest(
    [OTel("gen_ai.request.model")] string Model,
    [OTel("gen_ai.request.max_tokens")] int? MaxTokens,
    [OTel("gen_ai.request.temperature", SkipIfNull = false)] double? Temperature);

The source generator creates extension methods:

// Generated
activity.SetTagsFromChatRequest(request);

ActivitySources

Source Description
ANcpSdk.GenAi GenAI SDK instrumentation
ANcpSdk.Db Database instrumentation

Infrastructure wiring in ANcpSdkServiceDefaults.cs:

.AddSource("ANcpSdk.*")  // Subscribes to all ANcpSdk sources

Semantic Conventions

Constants in SemanticConventions.cs follow OpenTelemetry standards:

SemanticConventions.GenAi.System       // "gen_ai.system"
SemanticConventions.GenAi.RequestModel // "gen_ai.request.model"
SemanticConventions.Db.SystemName      // "db.system.name"
SemanticConventions.Db.QueryText       // "db.query.text"

Adding New Instrumentation

  1. Add ActivitySource to ActivitySources.cs
  2. Add semantic conventions to SemanticConventions.cs
  3. Create instrumentation class in appropriate subfolder
  4. Subscribe to source in ANcpSdkOpenTelemetryConfiguration.cs
