Command-line utilities
PRM is a comprehensive product. In addition to an easy-to-use GUI tool for configuration, PRM has
several command-line utilities for administrators and users to control and monitor its operation. The
PRM command-line utilities provide the same control functionality as the PRM GUI, plus additional
monitoring features.
• prmconfig—Enables an administrator or an automated script (with appropriate authorization) to
change the PRM configuration by loading a new PRM configuration definition, enable or disable
individual resource controls, and modify operational parameters for individual resource controls.
prmconfig also displays the current PRM configuration information and operational parameters.
• prmlist—Displays the current PRM configuration information and operational parameters.
• prmmonitor—Displays the resource consumption of the PRM groups.
• prmrun—Invokes the specified application in a specified PRM group. Non-administrative (non-root)
users must have authorization to access the specified PRM group.
• prmmove—Moves the specified process, process group, or user’s processes to the specified PRM
group. Non-administrative (non-root) users must have authorization to access the specified PRM
group.
• prmanalyze—Shows patterns in resource usage to help you fine-tune your PRM configurations. In
addition, it can be used even when you are not using PRM to perform resource use analysis and
capacity planning.
• prmavail—Displays available system CPU, memory, and LVM volume group/VxVM disk group
resources.
The PRM command-line utilities can be executed from properly authorized scripts or applications to
modify PRM operation as needed to adjust to changing workloads and priorities.
Graphical interface
PRM provides a graphical user interface, or GUI, that simplifies the monitoring and configuration of
HP PRM. The PRM GUI, which is integrated with both HP System Management Homepage and HP
Systems Insight Manager, enables you to create and modify configuration information through easy-
to-use dialog screens. The GUI also enables you to control PRM operation by loading configurations
and enabling or disabling individual controls for CPU, memory, and disk I/O bandwidth resources.
