Linux Best Management Practices

Overview

One of the most significant new features of the HPE ProLiant Gen8 servers is support of Agentless Management. Prior to introducing this feature, traditional management systems required SNMP agents and similar software to run on the OS. Now, when iLO 4 is configured for Agentless Management, it runs an SNMP agent, allowing the HPE ProLiant Gen8 host to be agentless (no SNMP agent needs to run on the host OS). HPE ProLiant Gen8 Servers provide SNMP v1 agents that run on the Integrated Lights-Out 4 (iLO 4) management controller. The iLO SNMP management agents provide access to SNMP elements that are important to the overall condition of the server, even when the server is powered off or in the process of starting the operating system. Once the iLO network cable is plugged in and the server powered up, the server is inherently manageable via iLO. The iLO monitors the health of the server and sends SNMP alerts.
HPE provides an Agentless Management Service (AMS) for Red Hat Enterprise Linux that allows iLO 4 to support host-related SNMP entities. The iLO 4 SNMP agent communicates with HPE AMS on the Red Hat Enterprise Linux host. The Agentless Management Service provides iLO 4 with valuable information about the operating system.
