Creating a Controller Node CPU Performance Report
The Controller Node CPU Performance report displays CPU time, interrupts, and context switches
in various service time buckets. CPU time is displayed as a percentage of user, system, and idle
mode, with each mode shown in a different color on the same chart. Charts can be generated for
values over a time interval or at a specified time. The X-axis (category) represents time, and the
Y-axis (value) indicates a percentage or number, depending on the type of chart.
Y-Axis Units Chart Type
Percentage of time in user, system, and idle mode. CPU Time
Number of interrupts per second. CPU Interrupts
Number of context switches per second. CPU Context Switches
A table below the charts lists the chart data time increments within the selected time interval. For
values at a specified time chart types, the table may also contain the node number and CPU
number.
