Hi @sreejeet nambiar ,
that is correct and this is also clearly listed here:
Enable Service Log on for run as accounts
Earlier version of Operations Managers has Allow log on locally as the default log on type. Operations Manager 2019 uses Service Log on by default. This leads to the following changes:
Health service uses log on type Service by default. Operations Manager 1807 and earlier versions, it was Interactive.
Operations Manager action accounts and service accounts now have Log on as a Service permission.
Action accounts and Run As accounts must have Log on as a Service permission to execute MonitoringHost.exe.
