using mysql - there tool can show live log of sql commands mysql engine receives?

a. helpfull see explain plan dml commands.
b. helpfull if turned on , off on mysql server no need restart service.
c. open source/free mysql nice.

you first need activate general query log. there must tools around parse log, favourite being :

tail -f /path/to/mysql.log
