MySQL 事件跟踪器

/*第一步 创建以下两个 日志表 */

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';

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';

/*第二步 在数据库上开启 查询日志 */

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

/*第三步 查询日志 */
select * from mysql.general_log;

/*第四步 在数据库上关闭 查询日志 */

SET global general_log = 0;

/*第五步 清除数据库 日志 */

truncate table mysql.general_log;
