MeasureWare Data Walkthrough:Global CPU Graph• GBL_CPU_SYS_MODE_UTIL• Percentage of time the CPU was in system mode during the interval.• This metric is a subset of the GBL_CPU_TOTAL_UTIL percentage.• A UNIX process operates in either system mode (also called kernelmode) or user mode. When a process requests services from theoperating system with a system call, it switches into the machine'sprivileged protection mode and runs in system mode.• This is NOT a measure of the amount of time used by systemdaemon processes, since most system daemons spend part of theirtime in user mode and part in system calls, like any other process.• On a system with multiple CPUs, this metric is normalized. That is,the CPU used over all processors is divided by the number ofprocessors online. This represents the usage of the total processingcapacity available.March 2004 Copyright © 2004 HP corporate presentation. All rights reserved. 46
MeasureWare Data Walkthrough:Global CPU Graph• GBL_CPU_USER_MODE_UTIL• The percentage of time the CPU was in user mode during the interval.• This metric is a subset of the GBL_CPU_TOTAL_UTIL percentage.• On a system with multiple CPUs, this metric is normalized. That is,the CPU used over all processors is divided by the number ofprocessors online. This represents the usage of the total processingcapacity available.• High user mode CPU percentages are normal for computationintensiveapplications. Low values of user CPU utilization comparedto relatively high values for GBL_CPU_SYS_MODE_UTIL canindicate an application or hardware problem.• User CPU is the time spent in user mode at a normal priority, at realtimepriority, and at a nice priority.March 2004 Copyright © 2004 HP corporate presentation.
