- Metric was originally added to mig-controller in fusor/mig-controller#379, got feedback from Clayton - Metric name was adjusted after consulting with @lilic and @smarterclayton in fusor/mig-controller#385 - Metric was added to mig-operator in fusor/mig-operator#193 - Metric is intended to help us understand at a high level how customers are using app workload migration tooling (CAM) to move apps and PV data between OpenShift clusters, especially when moving from OpenShift 3->4. Have finished the test of this feature against ocp4.4 + CAM 1.1.2 stage. It seems the feature has worked.
Below are the key test steps:
$oc edit ns openshift-migration
apiVersion: v1
kind: Namespace
metadata:
annotations:
openshift.io/node-selector: ""
labels:
control-plane: controller-manager
controller-tools.k8s.io: "1.0"
openshift.io/cluster-monitoring: "true" // add this line
name: "openshift-migration"
$ oc exec -it migration-controller-6d59b8c4c6-bqmqm /bin/bash
Defaulting container name to cam.
Use 'oc describe pod/migration-controller-6d59b8c4c6-bqmqm -n openshift-migration' to see all of the containers in this pod.
bash-4.4$ curl http://mig-controller-metrics.openshift-migration.svc.cluster.local:2112/metrics
# HELP cam_app_workload_migrations Count of MigMigrations sorted by status and type
# TYPE cam_app_workload_migrations gauge
cam_app_workload_migrations{status="completed",type="final"} 1
cam_app_workload_migrations{status="completed",type="stage"} 0
cam_app_workload_migrations{status="failed",type="final"} 0
cam_app_workload_migrations{status="failed",type="stage"} 0
cam_app_workload_migrations{status="idle",type="final"} 0
cam_app_workload_migrations{status="idle",type="stage"} 0
cam_app_workload_migrations{status="running",type="final"} 0
cam_app_workload_migrations{status="running",type="stage"} 0
open "monitoring/metrics" page in OCP UI, query the metric "cam_app_workload_migrations" from the prometheus UI inside of OpenShift, can get the migration information from UI.
