select concat('update performance_schema.setup_instruments set enabled=''',enabled,''' where name=''',name,''';')
from performance_schema.setup_instruments where enabled='NO';
-- 备份setup_consumers
select concat('update performance_schema.setup_consumers set enabled=''',enabled,''' where name=''',name,''';')
from performance_schema.setup_consumers where enabled='NO';
-- commit
select 'commit;';
二、执行setup.txt文件，备份performance_schema的配置。
mysql -h localhost -P 3306 -u root -pmysql -D test -s < d:\atmp\backup_perf_setup.sql > d:\ATMP\restore_perf_setup.sql
三、开启所有的setup配置进行监控。
update performance_schema.setup_instruments set enabled='YES' where enabled='NO'; update performance_schema.setup_consumers set enabled='YES' where enabled='NO'; commit;
四、监控完成后，还原performance_schema的配置。
D:\software\mysql\mysql-5.6.14-win32\bin>mysql -h localhost -P 3306 -u root -pmysql -D test -s < d:\ATMP\restore_perf_setup.sql
五、清空performance_schema的监控表的记录。
SELECT CONCAT('truncate table performance_schema.',table_name,';')
FROM information_schema.TABLES
WHERE table_schema='performance_schema'
AND table_name NOT LIKE 'setup%'
AND table_name NOT LIKE '%instances'
AND table_name NOT LIKE '%attrs'
AND table_name NOT IN ('performance_timers', 'threads');声明：本网页内容旨在传播知识，若有侵权等问题请及时与本网联系，我们将在第一时间删除处理。TEL:177 7030 7066 E-MAIL:11247931@qq.com
