Overview
This timeline analysis breaks the observation session duration into a number of (approximately) fixed-length, chronological time intervals. Each line represents one of these intervals. By default, 15 intervals are reported, each representing approximately the same number of samples. This illustrates any progressive CPU usage trends, such as blocks of intensive consumption or long periods of waits. The percentage value and the graph quantify CPU usage for an interval. The percentage is derived by dividing the number of samples CPU activity was observed by the number of samples in the interval. This, effectively, is the percentage of time the CPU was executing instructions.
A sample CPU Usage Timeline report is shown here:
