Ceph » mgr

k8sevents module is introduced in this PR: https://github.com/ceph/ceph/pull/29520

Start mgr in a non Kubernetes spawned cluster and find these lines in log:

2019-09-10T04:29:36.219+0000 7f2747939d40 -1 mgr[py] Module not found: 'k8sevents'

The behavior is correct since mgr is not in a Kubernetes spawned cluster.
But handling these exceptions will be nice.
