Answer: An "Uninteresting Connection" is a connection that isn't doing anything and isn't preventing any other connection from doing anything.

In particular, it's a connection that

• hasn't used any CPU time, issued any new requests, executed any commit or rollback operations or caused any pages to be written to the rollback log for a while,

• isn't holding any locks, and

• isn't blocking any other connections.

For example, if your Foxhound database contains a large amount of Monitor data for idle connections to a target database, check to see if those connections were holding any locks. If so, then the "Uninteresting Connections" purge criteria won't be satisfied; try using the "Purge all sample data: after 1 day ... 1 week ..." criteria instead.
