7 Add the datastore capacity chart to the charts.
a In the topology map, double-click the host.
The topology map refreshes with the host as the focus object.
b Click the datastore.
c In the metric list, which is updated to display datastore metrics, select Capacity > Available Space
(GB) and double-click the metric name.
8 Review the datastore capacity chart to determine if sucient capacity is available on the datastore to
support increasing the disk space on the virtual machine.
You know that you need to increase the size of the virtual disk on the virtual machine.
What to do next
Expand the virtual disk on the virtual machine and assign it to stressed partitions. Click Actions, located on
the object title bar, and open the virtual machine in the vSphere Web Client.
Creating and Using Object Details
The views and heat map details provide you with specic data about the object. You use this information to
evaluate problems in more detail. If the current views or heat maps do not provide the information that you
need, you can create one to use as tool as you investigate your specic problem.
Working with Heat Maps
With the vRealize Operations Manager heat map feature, you can locate trouble areas based on the metric
values for objects in your virtual infrastructure. vRealize Operations Manager uses analytics algorithms that
you can use to compare the performance of objects across the virtual infrastructure in real time using heat
maps.
You can use predened heat maps or create your own custom heat maps to compare the metric values of
objects in your virtual environment. vRealize Operations Manager has predened 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 dierent 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.
vRealize Operations Manager updates the heat maps in real time as new values are collected for each object
and metric. The colored bar below the heat map is the legend. The legend identies the values that the
endpoints represent and the midpoint of the color range.
Heat map objects are grouped by parent. For example, a heat map that shows virtual machine performance,
groups the virtual machines by the ESX hosts on which they run.
Create a Custom Heat Map
You can dene an unlimited number of custom heat maps to analyze exactly the metrics that you need.
Procedure
1 In the left pane of vRealize Operations Manager, click Environment.
2 Select an object to inspect from an inventory tree.
