super-smack压测工具

简介

super-smack是一款开源压测工具,支持MySQL、PostgreSQL、Oracle。本篇主要介绍一下使用super-smack压测MySQL体会。

1.SQL定义

2.数据字典定义

3.表结构

4.自动生成数据

5.SQL执行顺序与次数

6.多终端混合压测

MySQL性能表现与实际业务场景有很大关系。压测结果不代表正式生产环境容量，并且对于不同业务场景来说,QPS、TPS可能不再是决定性的指标。

安装

1. wgethttp://vegan.net/tony/supersmack/super-smack-1.3.tar.gz

2. tar xvzfsuper-smack-1.3.tar.gz

3../configure  --prefix=/usr/local/super-smack--with-mysql \

--with-mysql-lib=/app/mysql/lib\

--with-mysql-include=/app/mysql/include/mysql

4. make

5. make install

本次安装是针对MySQL。通过./configure  --help 可以看到帮助。

--with-mysql            Build with MySQL support

--with-pgsql            Build with PostgreSQL support

--with-oracle           Build with Oracle support

在64位系统面安装需要做一些变量声明修改。在github上面有相应patch

目录结构

gen-data

数据生成工具.用于生成数据表测试数据

./gen-data -n10000000 -f %48-64s%n,%32-64s,%n,%d >words.dat

1.-n 10000000 表示行数

2.-f 表示格式

3.s 表示字符串

4.n 表示序列

5.d 表示数字

super-smack

super-smack 客户主程序。用于发起压力测试，模拟操作客户端.

example smacks

模板文件一般有以下组成部分:

Client

client"admin"

{

user "用户名称";

host "主机";

db "数据库名称";

pass "密码";

socket "mysql  socket ";

}

Table

table "http_auth"

{

client "admin";

create "create table http_auth

(username char(64) not null primary key,

pass char(12),

mail char(16),

uid integer not null,

gid integer not null,

key mail_key (mail)

)";

min_rows"90000";

data_file"words.dat";

gen_data_file"gen-data -n 90000 -f %36-36s%n, %10-10s,%10-10s,%n,%d";

}

dictionary

dictionary"word"

{

type "rand"; //Seq、Unique、Rand

source_type "file"; // file、list、template

source "words.dat";

delim ",";

file_size_equiv "55000";

}

query

query"delete_by_username"

{

query "delete from  http_auth where username = '$word'";

type "delete_index";

has_result_set "y";

parsed "y";

}

smacker

client"smacker"

{

user "用户名称";

pass "用户密码";

host "主机";

db "数据库名称";

socket " mysql  socket ";

query_barrel "5 select_by_username ";

}

注：可以定义多个client.

main

main

{

smacker.init();

smacker.set_num_rounds($2);

smacker.set_num_rounds($2);

smacker.create_threads($1);

smacker.connect();

smacker.unload_query_barrel();

smacker.collect_threads();

smacker.disconnect();

}

注:

1.运行客户需要输入$1、$2 .$2表示循环次数,$1表示线程个数.

2.可以加入多个client

输出

./super-smack -dmysql  update-select-delete.smack -D/data/   10 10

输出结果:[此处我定义两个终端]

Query BarrelReport for client smacker1

connect:max=14ms  min=0ms avg= 6ms from 10clients

Query_type      num_queries     max_time        min_time        q_per_s

delete_index    60                 25              0            329.64

insert_index    50                 31              1            274.70

select_index    100                36              0            549.41

update_index    50                 31              0            274.70

Query BarrelReport for client smacker

connect:max=20ms  min=0ms avg= 5ms from 10clients

Query_type      num_queries     max_time        min_time        q_per_s

delete_index    60                4               0             328.13

insert_index    50                39              1             273.44

select_index    100               1               0             546.88

update_index    50                0               0             273.44

最后

1.可以自定义多个Query；

2.对于不同的查询需要定义多个数据字典；

3.支持多个客户端。
