Hi, I'm not sure if this have been solved since 12.2.4. The same code occurs in a different file in Github https://github.com/ceph/ceph/blob/ 50412f7e9c2691ec10132c8bf9310a05a40e9f9d/src/pybind/mgr/status/module.p y The ZeroDivisionError occurs when the dashboard is open, and there is a network outage (link between 2 datacenters is broken). I'm not sure about the behaviour of the actual UI in the dashboard at the same time.
