8 Fine-tuning your PRM
configuration
This chapter describes the optional step of fine-tuning your PRM
configuration.
To adjust your configuration, you may need to perform several iterations
of identifying resource use and assigning groups. Fundamentally, you
need to understand what processes are run by what users and the
percentages of resources they consume. How you collect this data
depends on how your processes or system load varies from day to day.
You can use the following tools to track resource use:
• PRM monitor (accessed by the prmmonitor command) shows the
percentage of CPU, memory, and disk bandwidth resources allocated
to and used by PRM groups.
• prmanalyze analyzes accounting files for data on resource usage and
contention.
• PerfView Analyzer analyzes how your system resources are used
over time.
• GlancePlus pinpoints resource use in real-time and sets alarms.
• acctcom displays process accounting record information.
• PRM memory message logging.
This chapter discusses the use of prmanalyze, GlancePlus, and message
logging.
