6.3

Only resource containers enabled for the capacity computations have relevant metrics. Not all metric types
are generated for all resource containers. For example, if CPU or memory resource containers are enabled in
a policy for density, but the network resource container is not, then cpu|density and mem|density metrics
are calculated but network|density metrics are not.
A capacity metric denition includes resource containers that act as a consumer or a provider. For example
in vSphere, the virtual machines are consumers of CPU and memory that the ESX host provides.

Metric Key Metric Name Generated for Description
capacityRemainingUsingConsumers_averag
e
Capacity
Remaining for
Average
Consumer
Prole
Provider Number of average-size consumers
that can t into the capacity
remaining. An average-size consumer
demands 50% of total capacity.
capacityRemainingUsingConsumers_small Capacity
Remaining for
Small
Consumer
Prole
Provider Number of small-size consumers that
can t into the capacity remaining. A
small-size consumer demands 0 - 33%
of the total capacity.
capacityRemainingUsingConsumers_mediu
m
Capacity
Remaining for
Medium
Consumer
Prole
Provider Number of medium-size consumers
that can t into the capacity
remaining. A medium-size consumer
demands 33-66% of the total capacity.
capacityRemainingUsingConsumers_large Capacity
Remaining for
Large
Consumer
Prole
Provider Number of large-size consumers that
can t into the capacity remaining. A
large-size consumer demands
66-100% of the total capacity.
capacityRemaining Capacity
Remaining (%)
Both Percent capacity remaining in the
resource container. For example, if the
resource container is memory and 2
GB out of 10 GB of memory is free,
the capacityRemaining = 20%.
underusedpercent Under used
(%)
Both Percent capacity not being used.
idletimepercent Idle time (%) Both Percent time a resource is idle based
on use over time. Time is a policy
seing. If not set, the default period is
30 days. For example, if a resource is
idle for a total of 6 days out of 30
days, idletimepercent = 20%.
wasteValue Reclaimable
Capacity
Both Amount of reclaimable capacity
based on consumer demand over
time. Time is a policy seing. If not
set, the default period is 30 days. For
example, if a vSphere host is
congured with 10 GB of memory but
only 2 GB of memory is used on
average over 30 days, then
wasteValue = 8 GB.
size.recommendation Recommended
Size
Both Capacity recommendation based on
demand over time. Time is a policy
seing. If not set, the default period is
30 days. For example, if consumer
demand is 2 GB of memory on
average over 30 days, then the
capacity recommendation is 2 GB.
