Update of the MCS templates failed after upgrade to UIM 8.51 SP1.
activate_template callback in mon_config_service probe fails after upgrade to 8.51 SP1 with the error message
"Failed to execute probe callback activate_template against probe /<domain>/<hub>/<robot>/mon_config_service. Received the following error: Callback error"
it has been identified that the cause is the problem is that the version column in the SSRV2Template table was not converted from "decimal" to "string" during the upgrade from UIM 8.51 to 8.51 SP1
the hotfix mon_config_service-8.5.2-HF1 resolves this case. It can be requested through a support case.
