Microsoft.Extensions.Telemetry

This library provides advanced logging and telemetry enrichment capabilities for .NET applications. It allows for detailed and configurable enrichment of log entries, along with enhanced latency monitoring and logging features. It is built for applications needing sophisticated telemetry and logging insights.

Install the package

From the command-line:

dotnet add package Microsoft.Extensions.Telemetry

Or directly in the C# project file:

<ItemGroup>
  <PackageReference Include="Microsoft.Extensions.Telemetry" Version="[CURRENTVERSION]" />
</ItemGroup>

Usage

Service Log Enrichment

Enriches logs with application-specific information based on ApplicationMetadata information. The bellow calls will add the service log enricher to the service collection.

// Add service log enricher with default settings
builder.Services.AddServiceLogEnricher();

// Or configure with options
builder.Services.AddServiceLogEnricher(options =>
{
    options.ApplicationName = true;
    options.BuildVersion = true;
    options.DeploymentRing = true;
    options.EnvironmentName = true;
});

Latency Monitoring

Provides tools for latency data collection and export. The bellow example uses the built-in Console exporter, but custom exporters can be created by implementing the ILatencyDataExporter interface.

// Add latency console data exporter with configuration
builder.Services.AddConsoleLatencyDataExporter(options =>
{
    options.OutputCheckpoints = true;
    options.OutputMeasures = true;
    options.OutputTags = true;
});

In order for the latency data to be exported, a call to ILatencyDataExporter.ExportAsync() is required. This can either be called manually, or by using the Request Latency Middleware inside the Microsoft.AspNetCore.Diagnostics.Middleware package by adding:

// Add Latency Context
builder.Services.AddLatencyContext();

// Add Checkpoints, Measures, Tags
builder.Services.RegisterCheckpointNames("databaseQuery", "externalApiCall");
builder.Services.RegisterMeasureNames("responseTime", "processingTime");
builder.Services.RegisterTagNames("userId", "transactionId");

// Add Console Latency exporter.
builder.Services.AddConsoleLatencyDataExporter();
// Optionally add custom exporters.
builder.Services.AddSingleton<ILatencyDataExporter, MyCustomExporter>();

// Add Request latency telemetry.
builder.Services.AddRequestLatencyTelemetry();

// ...

// Add Request Latency Middleware which will automatically call ExportAsync on all registered latency exporters.
app.UseRequestLatencyTelemetry();

Logging Enhancements

Offers additional logging capabilities like stack trace capturing, exception message inclusion, and log redaction.

// Enable log enrichment.
builder.Logging.EnableEnrichment(options =>
{
    options.CaptureStackTraces = true;
    options.IncludeExceptionMessage = true;
    options.MaxStackTraceLength = 500;
    options.UseFileInfoForStackTraces = true;
});

builder.Services.AddServiceLogEnricher(); // <- This call is required in order for the enricher to be added into the service collection.

// Enable log redaction
builder.Logging.EnableRedaction(options =>
{
    options.ApplyDiscriminator = true;
});

builder.Services.AddRedaction(); // <- This call is required in order for the redactor provider to be added into the service collection.
