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.
The Capacity 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 2‑8. Object Capacity States
Icon Description User Action
The capacity remaining for
the object is at normal
level.
No attention required.
The capacity remaining for
the object is less than the
normal level.
Check and take appropriate action.
