Several properties are shared between the different drilldowns. Modifying thresholds in one counter is not reflected in same counters in other drilldowns.
As an example the Information Store 'Receive Queue' and 'Send Queue' is on both the Main drilldown and the Storage Group drilldown. However, modifying the thresholds on the main drilldown is not reflected on the Storage Group drilldown.
STATUS.
This is currently a limitation of Spotlight on Messaging. Waiting for a fix in a future release of the Spotlight on Messaging
WORKAROUND
None. Thresholds have to be modified individually.
