Using the Reclaimable Waste Badge Under the Efficiency Badge
The vCenter Operations Manager Reclaimable Waste badge accounts for resource types such as CPU, memory,
or disk, and measures the extent of excessive provisioning for an object. It also identifies the amount of
resources that you can reclaim and provision to other objects in your virtual environment.
The Reclaimable Waste score ranges between 0 (good) and 100 (bad). The badge changes its color based on the
badge score thresholds that are set by the vCenter Operations Manager administrator.
Table 2-11. Reclaimable Waste States
Badge Icon Description User Action
No resources are wasted on the
selected object.
No attention required.
Some resource can be used
better.
Select Planning > Views to
identify underused resources.
Many resources are underused. Select Planning > Views to
identify underused resources.
Most of the resources on the
selected object are wasted.
Select Planning > Views to
identify underused resources.
No data is available for any of
the metrics for the time period.
The object is offline.
A vCenter Operations Manager administrator can change the badge score thresholds. For example, a green
badge can indicate a score below 50 instead of 75, as set by default.
Using the Density Badge Under the Efficiency Badge
The vCenter Operations Manager Density badge measures consolidation ratios to assess cost savings. You can
assess the behavior and performance of a virtual machine and related applications to maximize the
consolidation ratio without affecting the performance or service level agreements.
The density score is the ratio of the actual density to an ideal density based on the demand, the amount of
virtual capacity, and the amount of physical usable capacity. Density calculates the amount of resources that
you can provision before contention or conflict for a resource occurs between objects. The ratios account for
the number of virtual machines to host, the number of virtual CPUs to physical CPU, and the amount of virtual
memory to physical memory.
The Density score ranges between 0 (bad) and 100 (good). The badge changes its color based on the badge
score thresholds that are set by the vCenter Operations Manager administrator.
