Table 2-2. Object Health States (Continued)
Badge Icon Description User Action
The object might have serious
problems.
Check and take appropriate
action as soon as possible.
The object is either not
functioning properly or will stop
functioning soon.
Act immediately.
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
Health badge can indicate a score above 80 instead of 75, as set by default.
Using the Workload Badge Under the Health Badge
The vCenter Operations Manager Workload badge measures how hard an object must work for resources. A
workload score of 0 indicates that a resource is not being used and a score that approaches or exceeds 100 might
cause performance problems.
Workload is an absolute measurement that calculates the demand for a resource divided by the capacity of an
object. Resources might include CPU, memory, disk I/O, or network I/O.
The Workload score ranges from 0 (good) to over 100 (bad). The badge changes its color based on the badge
score thresholds that are set by the vCenter Operations Manager administrator.
Table 2-3. Object Workload States
Badge Icon Description User Action
Workload on the object is not
excessive.
No attention required.
The object is experiencing some
high resource workloads.
Check and take appropriate
action.
Workload on the object is
approaching its capacity in at
least one area.
Check and take appropriate
action as soon as possible.
Workload on the object is at or
over its capacity in one or more
areas.
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
Workload badge can indicate a score below 80 instead of 85, as set by default.
