Oracle Server Management Agents

Oracle Server Management Agents provide operating-system-specific agents to enable management and configuration of your Oracle servers.

Oracle Server Management Agents provides the following software:

• Oracle Server Hardware Management Agent

• Oracle Server Hardware SNMP Plugins

• The itpconfig tool enables you to configure a trap proxy to send traps between Oracle ILOM and the host server over the Host-to-ILOM Interconnect

This section contains a description of each of these parts.

Oracle Server Hardware Management Agent

The Oracle Server Hardware Management Agent (Hardware Management Agent) and associated Oracle Server Hardware SNMP Plugins (Hardware SNMP Plugins) provide a way to monitor and manage your server and server module's hardware using an operating system native agent. This in-band functionality enables you to use a single IP address (the host's IP) for monitoring your servers and blade server modules, without having to connect the management port of the Oracle Integrated Lights Out Manager (ILOM) service processor to the network.

The Hardware Management Agent and Hardware SNMP Plugins run on the host operating system of your Oracle servers, communicating with the Oracle ILOM service processor. The Hardware Management Agent daemon, called hwmgmtd, regularly polls the service processor for information about the current state of the server. Hardware Management Agent can poll the service processor for hardware information over either the Host-to-ILOM Interconnect, available on Oracle latest servers, or KCS interface on previous generation servers. This information is then made available by Hardware Management Agent over SNMP using the Hardware SNMP Plugins.

In addition, the Hardware Management Agent provides sensor and indicator readings by reading System Event Log (SEL) records stored on the service processor. The SEL records hardware events such as temperatures crossing a threshold. The Hardware Management Agent reads the service processor's SEL records and the host operating system's syslog and sends the appropriate SNMP traps using the OS-native SNMP daemon. Finally, the Hardware Management Agent also maintains a separate log that contains information about the Hardware Management Agent status, which can be used for troubleshooting.

Oracle Server Hardware SNMP Plugins

The Oracle Server Hardware SNMP Plugins consists of Net-SNMP plugins, that are compiled versions of hardware-specific Management Information Bases (MIB) which have been designed to enable you to monitor your Oracle servers effectively.

The sunHwMonMIB describes the state of sensors and alarms on your servers and provides the following information:

• Overall system alarm status

• Aggregate alarm status by device type

• FRU Alarm status

• Lists of sensors, sensor types, sensor readings, and sensor thresholds

• Indicator states

• System locator control

• Inventory including basic manufacturing information

• Product and chassis inventory information (such as serial number and part numbers)

• Per-sensor alarm status

The sunHwTrapMIB describes a set of traps for hardware events that can be generated by an Oracle server and provides the following information:

• Conditions affecting the environmental state of the server (such as temperature, voltage, and current out-of-range conditions)

• Error conditions affecting the hardware components in the server such as FRU insertion and removal and security intrusion notification

The sunStorageMIB provides the following information about system storage:

• Basic manufacturing information, properties, and alarm status for controllers

• Properties and alarm status for disks

• Properties and alarm status for RAID volumes

• Status of logical components

itpconfig and the ILOM Trap Proxy

The itpconfig command-line interface (CLI) tool configures Oracle ILOM to forward SNMP traps to the host over the Host-to-ILOM Interconnect, available on servers with the necessary hardware. See your server documentation to check if your server supports Host-to-ILOM Interconnect. You can also use itpconfig to configure the Host-to-ILOM Interconnect between Oracle ILOM service processors and the host.
