Using the Time Remaining Badge Under the Risk Badge
The vCenter Operations Manager Time Remaining badge measures the time before a resource associated with
an object reaches capacity. This badge indicates the available timeframe to provision or load balance the
physical or virtual resources for a selected object.
vCenter Operations Manager calculates the Time Remaining score as a percentage of time that is remaining
for each compute resource compared to the provisioning buffer you set in the Configuration dialog box. By
default, the Time Remaining score provisioning buffer is 30 days. If even one of the compute resources has less
capacity than the provisioned buffer, the Time Remaining score is 0.
For example, if the provisioning buffer is set to 30 days, and the object that you selected has CPU resources for
81 days, memory resources for 5 days, disk I/O resources for 200 days, and network I/O resources for more
than one year, the Time Remaining score is 0, because one of the resources has capacity for less than 30 days.
The Time Remaining 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.
Table 2-7. Time Remaining States
Badge Icon Description User Action
The number of days that remain
is much higher than the score
provisioning buffer you
specified.
No attention required.
The number of days that remain
is higher than the score
provisioning buffer, but is less
than two times the buffer you
specified.
Check and take appropriate
action.
The number of days that remain
is higher than the score
provisioning buffer, but
approaches the buffer you
specified.
Check and take appropriate
action as soon as possible.
The number of days that remain
is lower than the score
provisioning buffer you
specified. The selected object
might have exhausted some of
its resources or will exhaust
them soon.
Act immediately.
No data is available for the Time
Remaining score.
The object is offline.
Using the Capacity Remaining Badge Under the Risk Badge
The vCenter Operations Manager Capacity Remaining badge measures the number of additional virtual
machines that the object can handle before reaching capacity.
The remaining virtual machines count represents the number of virtual machines that can be deployed on the
selected object, based on the current amount of unused resources and the average virtual machine profile for
the last "n" weeks. The remaining virtual machines count is a function of the same compute resources of CPU,
Mem, Disk I/O, Net I/O, and Disk Space that are used to calculate the Time Remaining score.
vCenter Operations Manager calculates the Capacity Remaining score as a percentage of the remaining virtual
machines count compared to the total number of virtual machines that can be deployed on the selected object.
