The Oracle Server Hardware Management Agent (Hardware Management Agent) and associated Oracle Server Hardware SNMP Plugins (Hardware SNMP Plugins) enable you to monitor and manage your server from the operating system (OS).
This in-band functionality enables you to use a single IP address (the host's IP) for monitoring your servers without having to connect the management port of the Oracle Integrated Lights Out Manager (ILOM) SP to the network.
