Limited Visibility of Systems/Scenarios Monitoring

Hi all,

I am looking for build a role for our Help Desk. This role should allow to access Technical Monitoring but only for a group of systems or technical scenarios. For instance the user created in the configuration SM_L1_<SID> matchs with my requirement but it is not posible to restrict the systems and technical scenarios.

Do you know which standard role or authorization object I can use for that?

Thanks in advanced.
