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 this new feature to 4.3.z.
