Table 4-2. Detailed Collection State Information (Continued)
Field Description
Last Collection Duration Length of time of the last collection cycle.
Metric Sparklines Graphical representations of the last collection cycle duration and the number of
metrics and resources that the adapter collected during that cycle.
Collection Status Values
The collection status value for a resource indicates whether vCenter Operations Manager is receiving data for
the resource. Collection status values appear in a pop-up window when you point to an icon in the Collection
Status column in the resource list on the Environment Overview page.
If vCenter Operations Manager collects metrics for a resource through more than one adapter instance, a
separate icon appears for each adapter instance in the Collection Status column.
A resource has a status value only if its collection state is Collecting. For information about collection states,
see “Collection States,” on page 28.
