SOLMAN Monitoring: SAP Business Objects + Nagios Integration

Hello SAP Solution Manager experts,

we are using System monitoring function (RZ20) within SAP Solution Manager (EHP1, SPS 25).

We have following questions:

1) what is the possibility of monitoring of SAP Business Objects within SAP Solution Manager (SMSY, RZ20, Installation of agents)?

2) what it the procedure of integration of Nagios within SAP Solution Manager?

Thank you very much!
