Windows Disk collections failing after registration

After registering a Windows application, Disk and/or Disk I/O collections may not be available. The Windows application has 2 different methods for collecting Disk data, and 3 different methods for collecting Disk I/O data. When a Windows application is registered, Longitude will make a best guess as to which version of collector to use, but may need to use an alternate collector if the initial collector fails. After several consecutive collection failures, the Disk or Disk I/O collection method will failover to an alternate method. Since Windows Disk Collections are scheduled every hour, it may take several hours for the collection method to be modified.
