Melic.AgentFramework.Observability

OpenTelemetry-native observability for the Microsoft Agent Framework (MAF). Adds session identity tracking, per-session token aggregation, custom business tags, optional session-scoped parent spans, tool-call span enrichment, and export-boundary telemetry redaction — all without modifying MAF internals.

Packages

Package Purpose
Melic.AgentFramework.Observability Recommended metapackage — installs Sessions, Tools, and Redaction together
Melic.AgentFramework.Observability.Abstractions Shared attribute constants (SessionAttributeNames, ToolAttributeNames) and adapter contracts
Melic.AgentFramework.Observability.Sessions Session lifecycle tracing — enriches every invoke_agent span with genai.session.* tags
Melic.AgentFramework.Observability.Tools Tool-call tracing — enriches MAF execute_tool spans with bounded payload and retry attributes
Melic.AgentFramework.Observability.Redaction Export-boundary trace redaction — masks selected sensitive span attributes before export

Quick Start

using Melic.AgentFramework.Observability.Redaction;
using Melic.AgentFramework.Observability.Sessions;
using Melic.AgentFramework.Observability.Tools;
using OpenTelemetry;
using OpenTelemetry.Trace;

// Register the middleware (order matters: UseOpenTelemetry must be outermost)
var agent = new AIAgentBuilder(innerAgent)
    .UseOpenTelemetry()       // outermost — creates the invoke_agent span
    .UseSessionTelemetry()    // innermost — enriches the open span
    .UseToolTelemetry()       // enriches execute_tool spans for tools
    .Build();

// Each AgentSession gets a stable, auto-generated session ID automatically.
// Optionally assign your own:
session.AssignSessionId("order-42");

// Optionally attach business context tags:
session.SetSessionTag("tenant.id", "contoso");
session.SetSessionTag("user.tier", "premium");

using var tracerProvider = Sdk.CreateTracerProviderBuilder()
    .AddSource("Experimental.Microsoft.Agents.AI")
    .AddSource("Melic.AgentFramework.Observability.Sessions")
    .AddSource("Melic.AgentFramework.Observability.Tools")
    .AddTelemetryRedaction()
    .AddConsoleExporter()
    .Build();

Installing the metapackage is the recommended entrypoint for most consumers. If you only want part of the suite, you can still install Sessions, Tools, and Redaction individually.

Key Features

  • Zero-config session IDs — every session gets a stable genai.session.id automatically
  • Token aggregation — genai.session.input_tokens and genai.session.output_tokens accumulate across all turns
  • Custom tags — attach arbitrary genai.* business context to every span in a session
  • Mode B tracing — opt-in explicit parent span via BeginSessionTrace() for visual trace trees
  • Tool-call enrichment — adds stable genai.tool.* attributes to MAF execute_tool spans
  • Payload diagnostics — optional valid-JSON input and output capture with bounded size
  • Retry detection — repeated tool call ids are marked with retry attributes within the current invocation
  • Telemetry redaction — selected high-risk tool and GenAI attributes can be masked before export
  • OTel-only dependencies — depends only on OpenTelemetry.Api, no MAF internals
