If you have an ACL-entry for that particular host you can use "show access-list" where you see the hit-count at the end of the ACE.
The more general way is to enable logging to a SYSLOG-server, where you can filter for "build connections" and your IP.
If you want a free graphical user-interface you could try PLA (PIX logging architecture). This software is not maintained for many years but still works fine.
