Oracle Hardware Management Pack features two components: an SNMP monitoring agent and a family of cross-operating system command-line interface tools (CLI Tools) for managing your system.
Hardware Management Agent SNMP Plugins – SNMP is a standard protocol that monitors or manages a system. With the Hardware Management Agent SNMP Plugins, you can use SNMP to monitor Oracle systems in your data center with the advantage of not having to connect to two management points: the host and Oracle ILOM. This functionality enables you to use a single IP address (the host’s IP address) to monitor multiple systems.
The SNMP Plugins run on the host OS of Oracle systems. The SNMP Plugin extends the native SNMP agent in the host OS to provide additional Oracle MIB capabilities. Oracle Hardware Management Pack itself does not contain an SNMP agent. For Oracle Linux, a module is added to the net-snmp agent. For Microsoft Windows, the plugin extends the native SNMP service. Any security settings related to SNMP for the Oracle Hardware Management Pack are determined by the settings of the native SNMP agent or service, and not by the plugin.
Note that SNMPv1 and SNMPv2c provide no encryption and use community strings as a form of authentication. SNMPv3 is more secure and is the recommended version to use because it employs encryption to provide a secure channel, as well as individual user names and passwords.
