Microsoft OpenTelemetry Distro

Systemkrav: Python 3.10 eller senare.

pip install microsoft-opentelemetry

Systemkrav: Node.js 18 eller senare. ESM-appar kräver Node.js 20.6.0 eller senare.

npm install @microsoft/opentelemetry

node --import @microsoft/opentelemetry/loader ./dist/index.js

Installera paketet Microsoft.OpenTelemetry NuGet. Detta enda paket inkluderar Agent 365 runtime för överskådlighet, hostingintegrering, autoinstrumentering för stödda AI-ramverk samt standard OpenTelemetry-bibliotek.

<PackageReference Include="Microsoft.OpenTelemetry" />

Eller använd .NET CLI:

dotnet add package Microsoft.OpenTelemetry

Anropa use_microsoft_opentelemetry() för att aktivera observerbarhet.

from microsoft.opentelemetry import use_microsoft_opentelemetry
from microsoft.opentelemetry.a365.hosting.token_cache_helpers import AgenticTokenCache

token_cache = AgenticTokenCache()

use_microsoft_opentelemetry(
    enable_a365=True,
    a365_token_resolver=lambda agent_id, tenant_id: (
        (t := asyncio.run(token_cache.get_observability_token(agent_id, tenant_id)))
        and t.token or None
    ),
)

För anpassad tokenupplösning (istället för standardtokenlösare), se Manual token resolver.

Du kan anpassa exporterbeteendet genom att skicka valfria a365_* kwargs till use_microsoft_opentelemetry().

Använd ObservabilityManager tillsammans med AgenticTokenCacheInstance för att hantera token-cache automatiskt:

import { useMicrosoftOpenTelemetry, AgenticTokenCacheInstance } from '@microsoft/opentelemetry';
import { resourceFromAttributes } from '@opentelemetry/resources';

useMicrosoftOpenTelemetry({
  resource: resourceFromAttributes({
    'service.name': 'Default Token Cache Sample',
    'service.version': '1.0.0',
  }),
  azureMonitor: {
    enabled: Boolean(process.env.APPLICATIONINSIGHTS_CONNECTION_STRING),
  },
  instrumentationOptions: {
    http: { enabled: false },
  },
  a365: {
    enabled: process.env.ENABLE_A365_OBSERVABILITY_EXPORTER !== 'false',
    tokenResolver: (agentId, tenantId) =>
      AgenticTokenCacheInstance.getObservabilityToken(agentId, tenantId) ?? '',
  },
});

För anpassad tokenupplösning (istället för standardtokenlösare), se Manual token resolver.

Du kan konfigurera exportörens beteende genom att ange valfria egenskaper på a365-objektet.

För fullständiga konfigurationsalternativ och miljövariabler, se README-filen i JavaScript-repositoryt.

I Program.cs, anropa UseMicrosoftOpenTelemetry() för att aktivera observerbarhet. Uppräkningen ExportTarget styr var telemetrin skickas – kombinera mål med | (till exempel ExportTarget.Console | ExportTarget.Agent365).

Auto (DI) token-cache (rekommenderas för Agent Framework-appar):

Om du inte anger TokenResolver registreras IExporterTokenCache<AgenticTokenStruct> automatiskt av distron via DI. Din agent anropar RegisterObservability() under körning för att tillhandahålla autentiseringsuppgifter, och cachen hanterar tokenhämtning och uppdatering.

// Program.cs — no TokenResolver needed
builder.UseMicrosoftOpenTelemetry(o =>
{
    o.Exporters = ExportTarget.Agent365;
    // TokenResolver is auto-registered via the agentic token cache in DI, with required imports in the next code snippet.
});

using Microsoft.Agents.A365.Observability.Hosting.Caching;
using Microsoft.Agents.A365.Observability.Runtime.Common;

// In your agent class
public class MyAgent : AgentApplication
{
    private readonly IExporterTokenCache<AgenticTokenStruct> _agentTokenCache;

    public MyAgent(AgentApplicationOptions options,
        IExporterTokenCache<AgenticTokenStruct> agentTokenCache) : base(options)
    {
        _agentTokenCache = agentTokenCache;
    }

    protected async Task MessageActivityAsync(
        ITurnContext turnContext, ITurnState turnState, CancellationToken cancellationToken)
    {
        _agentTokenCache.RegisterObservability(
            turnContext.Activity.Recipient.AgenticAppId,
            turnContext.Activity.Recipient.TenantId,
            new AgenticTokenStruct(
                userAuthorization: UserAuthorization,
                turnContext: turnContext,
                authHandlerName: "AGENTIC"),
            EnvironmentUtils.GetObservabilityAuthenticationScope());
    }
}

    .build()
):
    # Any spans started in this context will receive these as attributes
    pass

För att automatiskt fylla i BaggageBuilder från TurnContext, använd hjälpredan populate i paketet microsoft-opentelemetry. Hjälparen extraherar automatiskt detaljer om uppringare, agent, tenant, kanal och konversation från aktiviteten.

from microsoft.opentelemetry.a365.core import BaggageBuilder
from microsoft.opentelemetry.a365.hosting.scope_helpers.populate_baggage import populate

builder = BaggageBuilder()
populate(builder, turn_context)

with builder.build():
    # Baggage is auto-populated from the TurnContext activity
    pass

import { BaggageBuilder, InvokeAgentScope, ExecuteToolScope } from '@microsoft/opentelemetry';

// Create and apply baggage context
const baggageScope = new BaggageBuilder()
  // Core identifiers
  .tenantId('tenant-123')
  .agentId('agent-456')
  .conversationId('conv-789')
  .build();

// Execute operations within the baggage context
baggageScope.run(() => {
  // All spans created within this context will inherit the baggage values

  // Invoke another agent
  const agentScope = InvokeAgentScope.start(request, scopeDetails, agentDetails);
  // ... agent logic

  // Execute tools
  const toolScope = ExecuteToolScope.start(request, toolDetails, agentDetails);
  // ... tool logic
});

För att automatiskt fylla i BaggageBuilder från TurnContext, använd hjälpredan fromTurnContext i paketet @microsoft/opentelemetry. Hjälparen extraherar automatiskt detaljer om uppringare, agent, tenant, kanal och konversation från aktiviteten.

import { BaggageBuilder, BaggageBuilderUtils } from '@microsoft/opentelemetry';

const baggageScope = BaggageBuilderUtils.fromTurnContext(new BaggageBuilder(), context)
  .invokeAgentServer(context.activity.serviceUrl, 3978)
  .build();

baggageScope.run(() => {
  // Baggage is auto-populated from the TurnContext activity
});

using Microsoft.Agents.A365.Observability.Runtime.Common;

using var baggageScope = new BaggageBuilder()
    .TenantId("tenant-123")
    .AgentId("agent-456")
    .ConversationId("conv-789")
    .Build();
// Any spans started in this context will receive them as attributes.

För att automatiskt fylla i BaggageBuilder från ITurnContext, använd tilläggsmetoden FromTurnContext i paketet Microsoft.Agents.A365.Observability.Hosting. Denna metod extraherar automatiskt information om uppringare, agent, klientorganisation, kanal och konversation från aktiviteten.

using Microsoft.Agents.A365.Observability.Runtime.Common;
using Microsoft.Agents.A365.Observability.Hosting.Extensions;

using var baggageScope = new BaggageBuilder()
    .FromTurnContext(turnContext)
    .Build();

I Python registrerar du baggage-mellanprogrammet genom ObservabilityHostingManager.configure() istället för direkt på adaptern.

from microsoft.opentelemetry.a365.hosting import ObservabilityHostingManager, ObservabilityHostingOptions

options = ObservabilityHostingOptions(enable_baggage=True)
ObservabilityHostingManager.configure(adapter.middleware_set, options)

Mellanvaran hoppar över att sätta baggage för asynkrona svar (händelser av typ ContinueConversation) för att undvika att skriva över baggage som den ursprungliga förfrågan redan satt.

Registrera BaggageMiddleware på adaptern. Den extraherar automatiskt information om uppringare, agent, tenant, kanal och konversation från varje inkommande TurnContext och omsluter begäran i en baggage-omfattning.

import { BaggageMiddleware } from '@microsoft/opentelemetry';

// Option 1: Register middleware directly on the adapter
adapter.use(new BaggageMiddleware());

Alternativt kan du använda ObservabilityHostingManager för att konfigurera baggage-middleware tillsammans med andra hostingfunktioner.

import { ObservabilityHostingManager } from '@microsoft/opentelemetry';

const manager = new ObservabilityHostingManager();
manager.configure(adapter, { enableBaggage: true });

Mellanvaran hoppar över att sätta baggage för asynkrona svar (händelser av typ ContinueConversation) för att undvika att skriva över baggage som den ursprungliga förfrågan redan satt.

Registrera BaggageTurnMiddleware på adaptern. Den extraherar automatiskt information om uppringare, agent, tenant, kanal och konversation från varje inkommande ITurnContext och omsluter begäran i en baggage-omfattning.

using Microsoft.Agents.A365.Observability.Hosting.Middleware;

adapter.Use(new BaggageTurnMiddleware());

Mellanvaran hoppar över att sätta baggage för asynkrona svar (händelser av typ ContinueConversation) för att undvika att skriva över baggage som den ursprungliga förfrågan redan satt.

Om du behöver bagage på HTTP-nivå (till exempel för att ange tenant- och agent-ID innan Bot Framework-pipelinen körs), registrera ObservabilityBaggageMiddleware i ASP.NET Core-pipelinen med hjälp av UseObservabilityRequestContext extension-metoden. Du måste tillhandahålla en resolverfunktion som extraherar tenant-ID och agent-ID från HTTP-kontexten.

using Microsoft.Agents.A365.Observability.Hosting.Middleware;

app.UseObservabilityRequestContext((httpContext) =>
{
    // Extract tenant and agent IDs from your request context
    var tenantId = GetTenantIdFromContext(httpContext);
    var agentId = GetAgentIdFromContext(httpContext);
    return (tenantId, agentId);

När du ställer in TokenResolver explicit registreras inte den automatiska DI-token-cachen — din resolver används istället.

Använd configureA365Hosting för att registrera A365 middleware på adaptern. Denna mellanvara hanterar bagage och token-rörmos automatiskt.

import { configureA365Hosting } from "@microsoft/opentelemetry";

configureA365Hosting(adapter, {
  enableBaggage: true,
  enableOutputLogging: false,
});

Sätt enableOutputLogging: false om svarsinnehåll inte ska fångas som spanattribut.

// Program.cs — no TokenResolver needed
builder.UseMicrosoftOpenTelemetry(o =>

    o.Exporters = ExportTarget.Agent365;

});
