This function returns the number of attempted connections - both successful and unsuccessful - since SQL Server was last started.
 Transact-SQL syntax conventions
Syntax
@@CONNECTIONS  
Return types
integer
Remarks
Connections are different from users. An application, for example, can open multiple connections to SQL Server without user observation of those connections.
Run sp_monitor for a report containing several SQL Server statistics, including count of connection attempts.
@@MAX_CONNECTIONS is the maximum allowed number of simultaneous connections to the server. @@CONNECTIONS increments with each login attempt; therefore, @@CONNECTIONS can exceed @@MAX_CONNECTIONS.
Examples
This example returns the count of login attempts as of the current date and time.
SELECT GETDATE() AS 'Today''s Date and Time',   
@@CONNECTIONS AS 'Login Attempts';  
Here's the result set.
Today's Date and Time  Login Attempts
