Jaeger Tracing with OpenTelemetry and AspNetCore

Jaeger Tracing with OpenTelemetry and ASP.NET Core

This is an example on how OpenTelemetry can be set up using Jaeger on ASP.NET Core

• Uses envoy proxy as ingress gateway
• Uses MassTransit and RabbitMQ as for messaging
• Traces are correlated end-to-end using JaegerPropagator

Running the solution

docker-compose up -d --build

Jaeger: http://localhost:16686

RabbitMq: http://localhost:15672 (guest/guest)

Telemetry Web Swagger (through Envoy proxy): http://localhost:10000/swagger/index.html

Monitoring service logs:

docker logs -f telemetry_web

docker logs -f telemetry_worker

docker logs -f envoy_proxy

Control the sampling rate

Jaeger client libraries ensure traces are always complete (includes all services end-to-end). Sampling decisions are propegated through service executions

Docs

On envoy/front-envoy-jaeger.yaml configure the sampler

See the Jaeger docs

100%:

sampler:
    type: const
    param: 1

10%:

sampler:
    type: probabilistic
    param: 0.1

2 requests per second:

sampler:
    type: ratelimiting
    param: 2.0
