clusterlifecycle-state-metrics

This project generates a number of metrics used for business analysis.

Available Metrics

• acm_managed_cluster_info

testing

1. make run
2. curl http://localhost:8080/metrics

Generated metrics:

curl http://localhost:8080/metrics
# HELP acm_managed_cluster_info Managed cluster information
# TYPE acm_managed_cluster_info gauge
acm_managed_cluster_info{hub_cluster_id="faddba46-201e-4d5d-bf52-9918517a9e6a",managed_cluster_id="faddba46-201e-4d5d-bf52-9918517a9e6a",vendor="OpenShift",cloud="Amazon",version="v1.16.2",created_via="Other",vcpu="4"} 1

Build/Push/Deploy on RHACM

Each steps can be run separatly:

Prereqs

1. oc login your hub RHACM cluster.
2. Set in the kustomization.yaml the namespace where you want the collector to be deployed.
3. Same for servicemonitor.yaml and clusterrole_binding.yaml
4. Set the following IMG environment variable, this is the name of the image and where it will be pushed.

export QUAY_USER=<your_user>
export IMG_TAG=<tag_you_want_to_use>
export IMG=quay.io/${QUAY_USER}/clusterlifecycle-state-metrics:${IMG_TAG}
make docker-build docker-push deploy

build

make docker-build

push

make docker-push

Deploy

make deploy

It also creates an ingress which allows to retrieve the infomration from outside of the cluster.

The metrics then will appear on prometheus.

promql examples:

1. Retrieve the number of imported clusters per hub:

sum by (hub_cluster_id) (
   acm_managed_cluster_info 
) 

and per vendor:

sum by (hub_cluster_id, vendor) (
   acm_managed_cluster_info 
) 

and per cloud:

sum by (hub_cluster_id, cloud) (
   acm_managed_cluster_info 
) 

and per version:

sum by (hub_cluster_id, version) (
   acm_managed_cluster_info 
)
