HP Capacity Advisor performs numerous functions.
At a fundamental level, it collects data from utilization monitoring
daemons on systems and workloads. Using this data, Capacity Advisor can
report on utilization of memory, core processing units, I/O bandwidth,
and power. It can calculate what resource utilization would look like
if the load were increased or decreased. Further, it can simulate
what resource utilization might look like if loads are combined. This
goes beyond simple addition of maximum loads to provide a dynamic
addition of components based on the time sequence of utilization measurements
taken from the actual loads running on real systems (see “Peaks and Sums”).
