For query execution statistics, you need to log slow queries. To do so,
enable following two directives in my.cnf file
long_query_time = 2
log-slow-queries = /var/log/mysql/mysql_slow_query.log
This configuration will log all queries that take more than 2 sec in the
file /var/log/mysql/mysql_slow_query.log
And monitor the logs.
Parsing the logs from human eyes is bit trivial. You can user this

perl
script to parse slow-queries.
