Metrics Collector
Metrics Collector implements a client to "scrape" or collect data from OpenShift Promethus and performs a push fedration to a Thanos instance hosted by Red Hat Advanced Cluster Management for Kubernetes hub cluster. This project is based on the Telemeter project.
Get started
To execute the unit test suite, run
make -f Makefile.prow test-unit
To build docker image and push to a docker repository, run
docker build -t {REPO}/metrics-collector:latest .
docker push {REPO}/metrics-collector:latest
{REPO} is the docker repository
Integration environment
Prerequisites: Commands kind and kubectl are required to setup an integration environment. To install them, run:
./test/integration/prereq.sh
If the image is pushed to a private repo which requires authentication, need to export the user/password for the docker repository before run setup.sh
export DOCKER_USER=<USER>
export DOCKER_PASS=<PASSWORD>
To launch a self contained integration environment based on the image built above, run:
./test/integration/setup.sh {REPO}/metrics-collector:latest
Above command will create a Kind cluster. Then prometheus and thanos will be deployed in the cluster. Finally, a deployment of metrics collector will be deployed, which will scrape metrics from prometheus and send metrics to thanos server.
To check/operate on the environment, run:
kubectl --kubeconfig $HOME/.kube/kind-config-hub {COMMAND}
{COMMAND} is the target kubectl command. e.g. to check the status for the deployed pods in the Kind cluster, run:
kubectl --kubeconfig $HOME/.kube/kind-config-hub get pods -n open-cluster-management-monitoring
To clean the integration environment, run:
./test/integration/clean.sh
