Description Sergiusz Urbaniak 2020-02-14 14:04:42 UTC

This bug was initially created as a copy of Bug #1803104

I am copying this bug because: 



Add metric gathering for cam_app_workload_migration_total.

- 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. 

The test logs have logged in https://bugzilla.redhat.com/show_bug.cgi?id=1803104

Approved to merge the new feature to 4.2.z.

Have finished the test of this feature against ocp4.2 + CAM 1.1.2 stage. It seems the feature has worked. 

Below are the key test steps:

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.
