2.5.5 Persona 的TCPP-MySQL测试工具

安装(在shell中执行)

 
wget https://github.com/Percona-Lab/tpcc-mysql 
unzip master.zip

#准备环境变量
export MYSQL_HOME=/usr/local/mysql/
export C_INCLUDE_PATH=$MYSQL_HOME/include
export PATH=$MYSQL_HOME/bin:$PATH
export LD_LIBRARY_PATH=$MYSQL_HOME/lib

cd tpcc-mysql-master/src
make all
cd ..

测试

查看数据库统计情况（自己总结的语句）

 
select TABLE_NAME, TABLE_ROWS,data_length/1024/1024 AS DATA_MB,index_length/1024/1024 as INDEX_MB ,(data_length+index_length)/1024/1024 as TOTAL_MB,TABLE_COLLATION   from information_schema.tables where table_schema='tpcc1000' order by TABLE_ROWS desc;

3.3.2 剖析单条性能

使用SHOW PROFILE

在会话级别使用

set profiling = 1;
show profiles;
show profile for query 1;

以上是默认输出，若要手动则执行以下语句：

select state ,sum(duration) as total_r ,
      round(
        100 * sum(duration) /
          (select sum(duration)
           from information_schema.profiling
           where query_id = @query_id
        ),2 ) as pct_r ,
      count(*) as calls,
      sum(duration) / count(*) as "R/Call"
     from information_schema.profiling
     where query_id =  @query_id
     group by state
     order by total_r desc;
