SQL Server Services monitoring for non-admin account

Are you able to see some services but not others (like when using Add Other Monitoring)? Some services may require modifying their own ACLs on top of modifying scmanager's, and sometimes you need special permissions to even make those changes. I only played with Service SDDLs a little bit so don't know much myself. I would try looking at the thread below, especially comments by Barb that might cover it in a bit more detail. The thread well predates LM's official support page so I don't know how well they align though.
