HP Systems Insight Manager 7.2 Technical Reference Guide

The provider package can supply the following categories of information in response to WBEM
queries. For more information see the HP WBEM Provider Data Sheets available separately.
• Power supplies: Name, ID, description, status, and availability
• Disk SMART sensors: System and state (online, failed/asserted, or unknown)
• Disk drives: ID, capabilities, size, and block size
• Disk partitions, logical systems, and logical disks: ID, bootable, and type
• Physical memory: Description, bank label, capacity, and memory type
• Physical memory statistical information: Single-bit errors, double-bit errors, and predictive
failure indicator
• Network adapters: Address, speed, maximum speed, duplex indicator, and count of octets
transmitted and received
• PCI systems: ID, vendor, grant time, and latency
• Physical media: Name, hot swap capability, capacity, manufacturer, model, serial number,
version, and other information
• SCSI controllers: ID, name, description, and protocol
HP WBEM Management Providers are available from the Linux link at http://www.software.hp.com.
WBEM providers for other HP equipment and operating systems are also available separately.
WBEM is a replacement for the SNMP network management protocol. WBEM providers perform
a similar role to SNMP agents of publishing information about a managed system. HP Integrity
servers can also be remotely managed using the HP SNMP Agents, which are available separately
from http://www.software.hp.com.

Process Resource Manager (HP PRM)
Process Resource Manager (HP PRM) enables you to focus the appropriate amount of system
resources exactly where you need them. This powerful resource management tool runs as in addition
to HP-UX. When PRM is enabled, groups of users or applications are guaranteed a specified
portion of the total system CPU processing cycles, of the available real memory resources, and of
the disk bandwidth to logical volume-managed (LVM) systems.
HP PRM is a resource management tool used to control the amount of resources that processes use
during peak system load (at 100% CPU, 100% memory, or 100% disk bandwidth utilization).
PRM can guarantee a minimum allocation of system resources available to a group of processes
through the use of PRM groups.
An HP PRM group is a collection of users and applications that are joined together and assigned
certain amounts of CPU, memory, and disk bandwidth. There are two types of PRM groups:
• FSS PRM groups
An FSS PRM group is a traditional PRM group, whose CPU entitlement is specified in shares.
This group uses the Fair Share Scheduler (FSS) in the HP-UX kernel within the system's default
processor set (PSET).
• PSET PRM groups
A PSET PRM group is a PRM group whose CPU entitlement is specified by assigning it a subset
of the system's processors (PSET). Processes in a PSET have equal access to CPU cycles on
their assigned CPUs through the HP-UX standard scheduler.
