Explanation:

When Foxhound is successfully gathering samples there is always at least one connection to the target database: the connection from Foxhound itself.

However, information about individual connections may not be recorded because it has been deleted or it was never recorded in the first place.

If that is the case, the blocked connections and current connections sections will display these messages:

   No detailed information about blocked connections is recorded for the sample taken at ...
   No detailed information about the ... connection(s) is recorded for the sample taken at ... 

Here are the reasons information about individual connections may not be recorded.

   The number of connections exceeded the Foxhound Options - Connection Sampling Threshold when the sample was recorded.
   The Monitor Options - Connection Sample Schedule was set to skip connections when the sample was recorded.
   The Foxhound Options - Purge process has deleted all the connection information for the sample.
