In order to shrink some of the reports, we renamed the templates from IIS - Internet Information Services to just IIS.
I thought this would change it on each of the nodes that were assigned to that template, but it didn't. They kept their old name. So I went into each one and renamed them individually to just IIS.
Then I noticed that each one that had be renamed, it no longer appeared in the Top 10 reports when you click on IIS under Applications tab. Things like Top 10 Processes by CPU Load or Top 10 Components by Statistic Data. They are all empty.
The only way to get data to show in those reports again is to rename each one back to the original name. It appears that these canned reports are actually tied to the original application monitor name instead of some other manner.
Any ideas? To test, look at one of your top 10 results for an application (IIS, SQL, Windows, etc). Rename the application monitor name for that node and it will disappear from the list.
