Make sure your docker containers are up and running.
If they are not, you can start them by running
docker compose up
whilst in the Green Metrics Tool
If you came here from interacting with applications → then
you can also directly use your
Otherwise we will set it up here.
Measuring a simple example load
We will make the most basic example our tool can handle:
- Using alpine base container.
- Add the package
- Just run a 5 seconds stress run with default metrics providers
So let’s start by going to the install folder of the Green Metrics Tool on your system
and then preparing the
cd PATH_TO_GREEN_METRICS_TOOL/docker docker compose up -d cd /tmp mkdir easiest-application cd easiest-application touch usage_scenario.yml git init . git add . git commit -m "All prepared for the energy test"
Now please copy the following code inside the
name: Stress Example author: Arne Tarara <[email protected]> description: Stress container on one core for 5 seconds services: simple-load-container: image: alpine setup-commands: - apk add stress-ng flow: - name: Stress container: simple-load-container commands: - type: console command: stress-ng -c 1 -t 5 -q note: Starting Stress
Under flow you see that we are just calling
stress-ng -c 1 -t 5,
which will stress our CPU for 5 seconds on one core.
cd PATH_TO_GREEN_METRICS_TOOL python3 runner.py --uri /tmp/easiest-application --name testing-my-demo
You should see an example output like so:
Having usage scenario .... .... .... Please access your report with the ID: XXXX-XXXX ...
Now you can view the report as the first item in your metrics dashboard at http://metrics.green-coding.internal:9142/request.html
If you have installed a cronjob → you can insert a new job at http://metrics.green-coding.internal:9142/request.html
It will be automatically picked up and you will get sent an email with the link to the results.
