Percent (%) CPU Utilization
Displays total system and process CPU consumption.
Guidelines
• Percentages are displayed as number of CPUs x 100%.
• Excessive use of CPU resources (greater than 80% of the total number of CPUs) may indicate
that the application load limit is close, even though the application may appear to be
performing well. At higher consumption rates, CPU consumption can become a bottleneck
to good performance.
• When system CPU consumption is significantly higher than process consumption, this may
indicate that “alien” or undesired processes are using CPU resources that the preferred
application could be using. It may also indicate that the application is abusing the operating
system kernel.
