For gen8 and higher you also need to configure the ILO for AMS monitoring and datacollection, AMS stands for Agrntless Management Service. For older generations you need the snmpd, snmp agents and Systrm managrment homepage.
The snmpd can be the net-snmp package,you need to configure snmp to let SIM access it, do you know how to do this?
For the AMS you only need the ams service and also the settings in the ILO like ams on, snmp community and destination.
