Users can analyze the CPU load average by Trend or by % Change. The load averages are displayed for 1, 5, and 15 minute intervals. Here is an example of the UI.
The key notion to remember between the 1, 5 and 15 minute averages is the fact that these numbers are averages collected over time. This means that a high number for the 1 minute average is less significant than a high average in the 5 and 15 minute ranges, because it may just be a “spike” and may resolve itself soon enough.
