Take a look at the sap_basis probe, it has the capability to monitor SAP HANA Metrics
sap_basis Metrics - CA Unified Infrastructure Management Probes - CA Technologies Documentation
I don't see the option to monitor MaxDB database, only Oracle and DB2 are available using the sap_basis probe as of now
There use to be another probe developed by a partner for SAP monitoring ,I remember it use to support the MaxDB monitoring . Not sure this one is still available
