Prime Infrastructure/ Assurance is positioned today more towards managing network elements and network performance, rather than server infrastructure. We are in the process of adding Datacenter component support, with more focus on Nexus and UCS- due later this year.
Having said that, Prime Infrastructure allows the system user to add custom SNMP polling templates, which can then be used for polling any SNMP based values from any SNMP enabled device. These can be used to collect the information you specified below and the polled information will be available in dashboards and reports.
