Oracle Hardware Management Pack for Oracle Solaris includes a Server Management Agent to help you monitor your Oracle servers.
Oracle Server Management Agent includes following components:
Oracle Server Hardware Management Agent
Oracle Server Hardware SNMP Plugins
itpconfig, a tool that enables you to forward traps generated by an Oracle ILOM service processor over the Host-to-ILOM Interconnect.
The Oracle Server Hardware Management Agent (Hardware Management Agent), called svc:/system/sp/management:default (called hwmgmtd in Oracle Solaris versions earlier than 11.2), enables you to monitor and manage your server and server module hardware from the OS. By default, the Hardware Management Agent manages the storage poller and provides Oracle ILOM information about storage devices in the system including any changes to these devices.
The default Hardware Management Agent configuration for polling provides the optimal functionality in systems where SNMP monitoring is not used.
Where host-based SNMP monitoring is used the Hardware Management Agent and associated Oracle Server Hardware SNMP Plugins (Hardware SNMP Plugins) run on the host operating system of your Oracle servers. The Hardware Management Agent regularly polls the Oracle ILOM service processor (SP) for information about the current state of the server. Collected information is then made available by Hardware Management Agent over SNMP using the Hardware SNMP Plugins.
The Hardware Management Agent polls the SP for hardware information either over the Host-to-ILOM Interconnect, available on Oracle's latest servers, or keyboard controller-style (KCS) interface on previous generation servers. 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) SP to the network.
In addition, the Hardware Management Agent maintains a separate log that contains information about the Hardware Management Agent status, which can be used for troubleshooting.
The Oracle Server Hardware SNMP Plugins consists of OS-native SNMP plugins and hardware-specific Management Information Base (MIB) files which have been designed to enable you to monitor your Oracle servers effectively using SNMP.
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
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. It 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
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 SP and the host.
In Oracle Hardware Management for Oracle Solaris 11.3 SRU 18, a feature was added that allows the trap proxy to notify the Hardware Management Agent when Oracle ILOM has sent a trap. Instead of regularly polling Oracle ILOM for information, detection of a trap will initiate an update cycle to get the newest data from Oracle ILOM. By default, if no traps trigger a polling cycle then Oracle ILOM is polled by the Hardware Management Agent once per hour. For more about this feature, see Hardware Management Agent Configuration File in Oracle Server Management Agent for Oracle Solaris 11.3 User’s Guide.
