Is there a limit on the number of servers or instances that uploads data to Project Lucy for a given User?
There is absolutely no limit on the number of instances that will automatically upload data to Project Lucy. However, this only applies to SQL Server and Windows servers. SQL Azure, Replication, Analysis Services and VMWare data are not used.
The XML files are created every 6 hours in the Lucy folder under the Diagnostic Server and are then zipped into one *.zip file at 3am when this file is uploaded to Lucy.
