Wrong upload and download speed measurement

[iAmSaugata]

Describe the bug
I have configured the setup with available docker image and managed to pull the data from Prometheus, but the speedtest data looks odd, I have 100 MBPS up/down fiber connection, and with this the download speed is showing in between 40-67 Mbps and upload speed only showing 600 to 800 Kbps. It looks like it is not generating the result properly, probably using old binary.

If you are having same problem, please use this Fork. You have to build your docker image from this, and this will use latest version of speedtest-go from https://github.com/showwin/speedtest-go

https://github.com/olqs/speedtest_exporter

Note : If you are using Raspberry Pi 64 Bit, then you have to change ENV GOARCH=amd64 to ENV GOARCH=arm64 in Dockerfile.

This works fine, but still the internet speed test result are not 100% correct, and it is because of speedtest-go implementation.

Thanks for olqs for this update.

Hi

Thanks for your answer. I have tried the recommended repo and I see, that the speedtest always use the same speedtest server now, and the speeds are also higher. But not such as I expected.

I'm writing instructions for those, who are not familiar with Docker and need to rebuild that repo.

I have built the repo for arm64 (Raspberry PI 4) - you can use this link https://hub.docker.com/r/mathosk/speedtest_exporter/tags

Instructions - if you want to use my arm64 rpi 4 docker image:

Do changes in locally fetched https://github.com/danopstech/starlink project

Turn off the starlink project
sudo docker-compose down

vim docker-compose.yaml

Rewrite the compose - use my prebuilded image:

  speedtest_exporter:
    image: "mathosk/speedtest_exporter:arm64_latest"
    #entrypoint: ["/speedtest_exporter", "-server_id", "11213", "-server_fallback"]
    restart: always
    ports:
      - "9092:9090"

Pull the new docker image
sudo docker-compose pull

Start the project
sudo docker-compose up --remove-orphan

Instructions - if you want to rebuild the repo

Login to your raspberry pi

mkdir ~/docker-builds
cd ~/docker-builds
wget https://github.com/olqs/speedtest_exporter
cd speedtest_exporter

vim Dockerfile
If you are using Raspberry Pi 64 Bit, then you have to change ENV GOARCH=amd64 to ENV GOARCH=arm64 in Dockerfile.

Build the image
sudo docker build --no-cache -t YOUR_DOCKER_HUB_USER/speedtest_exporter:arm64_latest .

If you want to push the image to your Docker Hub account (optional), login
sudo docker login --username=YOUR_DOCKER_HUB_USER

Note: you do not need to push the image to Docker Hub. You can use your locally builded image instead - skip this step in such a situation
sudo docker push YOUR_DOCKER_HUB_USER/speedtest_exporter:arm64_latest

Logout from Docker hub, only if you was logged in
sudo docker logout

Do changes in locally fetched https://github.com/danopstech/starlink project, in docker-compose.yaml

Rewrite the docker-compose - use YOUR prebuilded image source - change YOUR_DOCKER_HUB_USER to the value you set for docker build step

  speedtest_exporter:
    image: "YOUR_DOCKER_HUB_USER/speedtest_exporter:arm64_latest"
    #entrypoint: ["/speedtest_exporter", "-server_id", "11213", "-server_fallback"]
    restart: always
    ports:
      - "9092:9090"

optional - you have the repo available locally already
sudo docker-compose pull

start the project
sudo docker-compose up --remove-orphan
