This object reports CPU utilization averaged over the trailing five minutes, giving a longer-window smoothed trend than the one-minute average reported elsewhere in this MIB. An admin compares this to the 1-minute figure to see whether load is rising, falling, or steady over a slightly longer horizon before deciding whether to act. For example, a 5-minute average of 40 alongside a 1-minute average of 90 would indicate a load spike that just started, rather than a sustained high-CPU condition.
