HP Integrity Essentials Capacity Advisor performs numerous functions. At a fundamental
level, it collects data from utilization monitoring daemons on systems and
workloads. Using this data, it can report on utilization of memory and
core processing units. Based on this data, it can be used to calculate
what the utilization would look like if the load were increased or
decreased. Going further, it can simulate what utilization will 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”).
