Jaeger Exporter for OpenTelemetry .NET

NuGet NuGet

The Jaeger exporter converts OpenTelemetry traces into the Jaeger model following the OpenTelemetry specification.

The exporter communicates to a Jaeger Agent through the thrift protocol on the Compact Thrift API port, and as such only supports Thrift over UDP.

Supported .NET Versions

This package supports all the officially supported versions of .NET Core.

For .NET Framework, versions 4.6.1 and above are supported.

Prerequisite

Installation

dotnet add package OpenTelemetry.Exporter.Jaeger

Configuration

You can configure the JaegerExporter through JaegerExporterOptions and environment variables. The JaegerExporterOptions setters take precedence over the environment variables.

Options Properties

The JaegerExporter can be configured using the JaegerExporterOptions properties:

  • AgentHost: The Jaeger Agent host (default localhost).
  • AgentPort: The compact thrift protocol UDP port of the Jaeger Agent (default 6831).
  • MaxPayloadSizeInBytes: The maximum size of each UDP packet that gets sent to the agent (default 4096).
  • ExportProcessorType: Whether the exporter should use Batch or Simple exporting processor (default ExportProcessorType.Batch).
  • BatchExportProcessorOptions: Configuration options for the batch exporter. Only used if ExportProcessorType is set to Batch.

See the TestJaegerExporter.cs for an example of how to use the exporter.

Environment Variables

The following environment variables can be used to override the default values of the JaegerExporterOptions.

Environment variable JaegerExporterOptions property
OTEL_EXPORTER_JAEGER_AGENT_HOST AgentHost
OTEL_EXPORTER_JAEGER_AGENT_PORT AgentPort

FormatException is thrown in case of an invalid value for any of the supported environment variables.
