Queries that ran, and the number of times they ran

Question

I want to profile a running web application in dev on a mysql 5.5 database. The web application uses hibernate and I am able to see that a rather large number of queries are run against the database.

I'm able to see long running queries with logging, but that is not a concern as they are all running fairly quickly.

What I would like to know is, what queries are being run, and how many times they are run.

for the query monitoring you have two solutions from MySQL level:

solution 1:

create log file for the query by editing my.ini or my.cnf

slow_query_log_file = "C:/slowquery.log"
log = log_file_name

solution 2:

Create log tables:

Slow queries:

CREATE TABLE `slow_log` (
   `start_time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP 
                          ON UPDATE CURRENT_TIMESTAMP,
   `user_host` mediumtext NOT NULL,
   `query_time` time NOT NULL,
   `lock_time` time NOT NULL,
   `rows_sent` int(11) NOT NULL,
   `rows_examined` int(11) NOT NULL,
   `db` varchar(512) NOT NULL,
   `last_insert_id` int(11) NOT NULL,
   `insert_id` int(11) NOT NULL,
   `server_id` int(10) unsigned NOT NULL,
   `sql_text` mediumtext NOT NULL,
   `thread_id` bigint(21) unsigned NOT NULL
  ) ENGINE=CSV DEFAULT CHARSET=utf8 COMMENT='Slow log'

General queries

CREATE TABLE `general_log` (
   `event_time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP
                          ON UPDATE CURRENT_TIMESTAMP,
   `user_host` mediumtext NOT NULL,
   `thread_id` bigint(21) unsigned NOT NULL,
   `server_id` int(10) unsigned NOT NULL,
   `command_type` varchar(64) NOT NULL,
   `argument` mediumtext NOT NULL
  ) ENGINE=CSV DEFAULT CHARSET=utf8 COMMENT='General log'


  SET global general_log = 1;
SET global log_output = 'table';

To show the log use the following command:

select * from mysql.general_log;

if you want the slow query:

select * from mysql.slow_log;

To count the number of query executing:

show session status like "Queries";

Queries that ran, and the number of times they ran
