As per above article we have provided least privileges for monitoring account on both SQL and Windows level.

After these changes we observer that we could not see any data under 'SQL Agent Jobs' 

As per the KB we have provided required permissions on MSDB. 

SQL agent job monitoring did not work even after reverting the permissions ( providing sysadmin on SQL).

Need your help to fix this issue. Because I did see any error around this.
