Maximum Fragmentation percent value of indexes does not match drilldown data.
On Spotlight dashboard the "Large Index Files" of "Maximum Fragmentation" percentage shows (79.6) a different percentage than what is shown in Fragmented Indexes drilldown. When user opens drilldown with the Show Details option, in Fragmented Indexes tab the highest percentage of "Average Fragmentation" column shows 5%. User expects that the alert would show the average for indexes over a certain number of pages (as seen in the "Show Details").
Issue fixed in the current release of Spotlight on SQL Server Enterprise. Latest version of Spotlight can be downloaded from here.
