We have upgraded UIM 8.5.1 to UIM 9.0.2. On Primary, service_host probe failed whereas on UMP, dashboard_engine probe failed.
Release : 9.0.2
Component : UNIFIED INFRASTRUCTURE MGMT
The service_host and dashboard_engine (and dap) probes were deprecated some time ago and they are not used in 9.x.
service_host was replaced by the wasp probe on the Primary hub.
These probes can be deactivated, then deleted.
