Bump Azure.Monitor.OpenTelemetry.Exporter from 1.5.0 to 1.6.0

[dependabot]

Updated Azure.Monitor.OpenTelemetry.Exporter from 1.5.0 to 1.6.0.

Release notes

Sourced from Azure.Monitor.OpenTelemetry.Exporter's releases.

1.6.0

1.6.0 (2026-01-16)

Features Added

• Upgraded api-verion to 2025-09-01.
• Make Azure.ResourceManager.Avs AOT-compatible.

1.6.0-beta.2

1.6.0-beta.2 (2026-01-12)

Breaking Changes

• Default Sampler Changed (#​54942): The default sampling behavior has been changed from
  ApplicationInsightsSampler with 100% sampling (all traces sampled) to
  RateLimitedSampler with 5.0 traces per second. This change significantly
  reduces telemetry volume for high-traffic applications and provides better
  cost optimization out of the box.
  Impact: Applications with more than 5 requests per second will see fewer
  traces exported by default.
  Migration: To maintain the previous behavior (100% sampling), explicitly
  configure the sampler:

  // Option 1: Set SamplingRatio and clear TracesPerSecond
  builder.Services.AddOpenTelemetry()
      .UseAzureMonitorExporter(options =>
      {
          options.SamplingRatio = 1.0f;
          options.TracesPerSecond = null;
      });
  // Option 2: Use environment variables
  // OTEL_TRACES_SAMPLER=microsoft.fixed_percentage
  // OTEL_TRACES_SAMPLER_ARG=1.0

Bugs Fixed

• Fixed performance counter metrics not using configured resource attributes
  (cloud_RoleName and cloud_RoleInstance), which previously showed
  "unknown_service:appName" instead of the configured values.
  (#​54944)

1.6.0-beta.1

1.6.0-beta.1 (2025-12-03)

Bugs Fixed

• Added Microsoft override attributes to preserve exact Application Insights
  semantics when exporting telemetry data.
  (#​54023)
  • Request: microsoft.request.name, microsoft.request.url,
    microsoft.request.source, microsoft.request.resultCode
  • Dependency: microsoft.dependency.type, microsoft.dependency.target,
    microsoft.dependency.name, microsoft.dependency.data,
    microsoft.dependency.resultCode
  • Operation: microsoft.operation.name

Other Changes

• Added distinct SDK version labels for all Application Insights shim packages
  to enable accurate attribution and visibility of exporter, distro, and shim
  telemetry during migration and analysis.
  (#​54011)

1.5.1

1.5.1 (2025-11-18)

Features Added
