Introduction The HP iLO Management Engine includes HP Agentless Management (referred to as “Agentless Management” in this document), the Active Health System, Intelligent Provisioning, as well as the traditional remote management and control capabilities delivered with the new, improved iLO 4 management processor. iLO 4 and Agentless Management are components of the HP ProActive Insight architecture 1 and integrated lifecycle automation built into HP ProLiant Gen8 servers.

• The capability for the iLO 4 to behave as a “Network Management Stack” firewall between network management protocol requests and the host-based applications/data stores. The exception here occurs when you use the SNMP pass-thru option. Client SNMP requests sent to iLO over the network pass to the host OS. The responses then pass to iLO and return to the client over the network. Alerts are not affected. The iLO Management Engine includes monitoring, diagnostic, and support capabilities.

The AMS is part of the HP Service Pack for ProLiant (SPP) which installs AMS by default and needs no additional configuration.

Management and maintenance When the iLO 4 default configuration for Agentless Management occurs, the iLO Management Engine alerts HP SIM 7. This is the preferred configuration and eliminates any potential for duplicate information from the managed server. Management with HP SIM 7 To manage a ProLiant Gen8 server using Agentless Management, your management server must use HP SIM 7.0 or later. You also need to configure SNMP parameters so that HP SIM can exchange information with the server.
PAGE 7
When to use to OS-based agents In some cases Agentless Management is not the best choice. This section expands on the information in Table 1 using examples of cases when OS-based agents continue to be the best monitoring and reporting solution. Monitoring performance If you want to detect, analyze, and explain hardware performance bottlenecks on HP ProLiant servers, Insight Control performance management (ICperf) is an effective software solution to accomplish those objectives.
