Working with Heat
Maps
With the
VMware Aria
Operations
heat map feature, you can locate trouble areas based on the metric
values for objects in your virtual infrastructure. VMware Aria
Operations
uses analytics algorithms that you can use to compare the
performance of objects across the virtual infrastructure in production using heat maps. You can use predefined heat maps or create your own
custom heat maps to compare the metric values of objects in your virtual environment.
VMware Aria
Operations
has predefined heat maps on the Details
tab that you can
use to compare commonly used metrics. You can use this data to plan to reduce waste and
increase capacity in the virtual infrastructure. What a Heat Map
Shows
A heat map contains
rectangles of different sizes and colors, and each rectangle represents an
object in your virtual environment. The color of the rectangle represents the
value of one metric, and the size of the rectangle represents the value of
another metric. For example, one heat map shows the total memory and percentage
of memory use for each virtual machine. Larger rectangles are virtual machines
with more total memory, green indicates low memory use, and red indicates high
use.
VMware Aria
Operations
updates the heat maps automatically as new
values are collected for each object and metric. The colored bar below the heat map
is the legend. The legend identifies the values that the endpoints represent and the
midpoint of the color range. Heat map objects group by
parent. For example, a heat map that shows virtual machine performance, groups
the virtual machines by the ESX hosts on which they run.
