SysBench系统性能基准测试工具

SysBench系统性能基准测试工具

一. 简介SysBench是一个模块化的、跨平台、多线程基准测试工具，主要用于评估测试各种不同系统参数下的数据库负载情况。当前功能允许测试的系统参数有：file I/O performance （文件I / O性能）scheduler performance （调度性能）memory allocation and transfer speed （内存分配和传输速度）POSIX threads implementation performance （POSIX线程执行绩效）database server performance (OLTP benchmark) （数据库服务器性能）SysBench运行指定数目的线程，他们都是并行的执行请求。实际工作量的请求产生依赖于指定的测试模式（在编译中添加测试模块）。可以限制请求总数或总时间为基准，或两者。

问题二：./sysbench: error while loading shared libraries: libmysqlclient.so.16: cannot open shared object file: No such file or directory解决办法：# ln -s /usr/local/mysql-5.5.8/lib/libmysqlclient.so.16 /lib64/libmysqlclient.so.16

通用选项:--num-threads=N 创建测试线程的数目。默认为1.--max-requests=N 请求的最大数目。默认为10000，0代表不限制。--max-time=N 最大执行时间，单位是s。默认是0,不限制。--forced-shutdown=STRING 超过max-time强制中断。默认是off。]--thread-stack-size=SIZE 每个线程的堆栈大小。默认是32K。--init-rng=[on|off] 在测试开始时是否初始化随机数发生器。默认是off。--test=STRING 指定测试项目名称。--debug=[on|off] 是否显示更多的调试信息。默认是off。--validate=[on|off] 在可能情况下执行验证检查。默认是off。
