kubernetes/test/instrumentation

This directory contains the regression test for controlling the list of stable metrics

If you add or remove a stable metric, this test will fail and you will need to update the golden list of tests stored in testdata/. Changes to that file require review by sig-instrumentation.

To update the list, run

./hack/update-generated-stable-metrics.sh

Add the changed file to your PR, then send for review.

If you want to test the stability framework, you can add metrics to the file in test/instrumentation/testdata/pkg/kubelet/metrics/metrics.go and run test verification via:

./test/instrumentation/test-verify.sh

To update the golden test list, you can run:

./test/instrumentation/test-update.sh

To update the list of documented metrics, please run:

./test/instrumentation/update-documentation-metrics.sh

To update the documented list of metrics for k8s/website, please run:

./test/instrumentation/update-documentation.sh

Then you need to copy the output to the appropriate website directory. Please define the directory in which the website repo lives in an env variable like so:

export WEBSITE_ROOT=<path to website root>

And then from the root of the k8s/k8s repository, please run this command:

cp ./test/instrumentation/documentation/documentation.md $WEBSITE_ROOT/content/en/docs/reference/instrumentation/metrics.md
