Table 2-5. Object Faults States
Badge Icon Description User Action
No faults are registered on the
selected object.
No attention required.
Faults of low importance are
registered on the selected object.
Check and take appropriate
action.
Faults of high importance are
registered on the selected object.
Check and take appropriate
action as soon as possible.
Faults of critical importance are
registered on the selected object.
Act immediately to avoid or
correct problems.
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
Faults badge can indicate a score below 40 instead of 25, as set by default.
Defining Risk to Assess Future Problems in vCenter Operations Manager
The vCenter Operations Manager Risk badge indicates a potential performance problem in the near future that
might affect the virtual environment.
Risk involves the time remaining, capacity remaining, and stress factors that account for the time buffer,
remaining virtual machines, and degree of habitual high workload.
vCenter Operations Manager calculates the risk score using the scores of the sub-badges that the Risk badge
contains. The formula that is applied to calculate the risk score is inverse geometric weighted mean.
The overall Risk score for an object ranges between 0 (no risk) to 100 (serious risk). The badge changes its color
based on the badge score thresholds that are set by the vCenter Operations Manager administrator.
Table 2-6. Object Risk States
Badge Icon Description User Action
The selected object has no
current problems. No problems
are expected in the future.
No attention required.
There is a low chance of future
problems or a potential problem
might occur in the far future.
Check and take appropriate
action.
There is a chance of a more
serious problem or a problem
might occur in the medium-term
future.
Check and take appropriate
action as soon as possible.
The chances of a serious future
problem are high or a problem
might occur in the near future.
Act immediately.
No data is available for any of
the metrics for the time period.
