Trace FastAPI with Jaeger through OpenTelemetry Python API and SDK.

Hello there 👋

Hi, I am @Blueswen (Yi-Wei, Liu), a Software Engineer focus on Web Application, DevOps, Cloud Native and Developer Experience.

Want to be a full stack developer, but just a stack overflow developer right now.

fastapi-jaeger's Issues

Error decoding 'jaeger' for 'exporters' in otel-collector-config.yaml

2023-11-17 16:32:30 Error: failed to get config: cannot unmarshal the configuration: 1 error(s) decoding:

small error for method name `error_test`

@app.get("/error_test")
async def random_sleep(response: Response):

it shall be error_test

f"http://localhost:8000/" here f is not needed.

[question] container names for compose from `app_b` -> `fastapi-jaeger_app-b_1`

Don't know what's the wrong with my env? I use podman-compose @ Mac, but it shall be the same.

forget how to fix it, I got the container name is fastapi-jaeger_app-a_1 with extra prefix fastapi-jaeger and suffix _1.

I have to change in all related areas to make it work as expected

• main.py like TARGET_ONE_HOST = os.environ.get("TARGET_ONE_HOST", "fastapi-jaeger_app-b_1") // from app_b
• docker-compose.yaml for naming
• config under etc

But I think it shall not work like this, what's wrong with my env? I use podman-compose @ Mac, but it shall be the same

Can you paste your console out in the readme, I got it like below.

$ podman ps

How to combine SPM with grafana?

Fantastic repo. I want to know if there's a way to show SPM in grafana?

Upload container image to repository

inject `TARGET_ONE_HOST` in `app_a` for customization

services:
  app-a:
    build: .
    ports:
      - "8000:8000"
    volumes:
      - ./src/fastapi_jaeger:/app
    environment:
      TARGET_ONE_HOST: "fastapi-jaeger_app-b_1"
      TARGET_TWO_HOST: "fastapi-jaeger_app-c_1"

In the docker-composer.yaml, it is better to inject above configurations (TARGET_ONE_HOST & TARGET_TWO_HOST

related with #2 (app_b could be good enough)
