【工具】基准测试工具之sysbench

原创 Linux操作系统 作者:杨奇龙 时间:2013-03-31 16:59:34 0 删除 编辑
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
它主要包括以下几种方式的测试:
1、cpu性能
2、磁盘io性能
3、调度程序性能
4、内存分配及传输速度
5、POSIX线程性能
6、数据库性能(OLTP基准测试)
目前sysbench主要支持 mysql,pgsql,oracle 这3种数据库。
一 前期准备
1 下载 sysbench
  http://sf.net/projects/sysbench/
2 安装:
[root@rac3 ~]# tar zxvf sysbench-0.4.12.tar.gz         
[root@rac3 ~]# cd sysbench-0.4.12
[root@rac3 sysbench-0.4.12]# ls
acinclude.m4  autogen.sh  config     configure.ac  doc      install-sh   Makefile.in  mkinstalldirs  README-WIN.txt  TODO
aclocal.m4    ChangeLog   configure  COPYING       INSTALL  Makefile.am  missing      README         sysbench
[root@rac3 sysbench-0.4.12]# ./autogen.sh 
[root@rac3 sysbench-0.4.12]# 
[root@rac3 sysbench-0.4.12]# ./configure 
--prefix=/usr/local/sysbench \             --指定sysbench的安装目录
--with-mysql-includes=/usr/include/mysql \ --mysql的头文件
--with-mysql-libs=/var/lib/mysql           --mysql 链接库文件
默认是支持mysql的,如果要测试oracle或者pgsql 必须使用--with-oracle ,--with-pgsql 比如:
Note 
如果是oracle,在.bash_profile文件中添加:
export CC=cc
export CXX=c++
export CFLAGS="-m64 -I /opt/oracle/11.2.0/alifpre/rdbms/public"
export CXXFLAGS="$CFLAGS"
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib 
编译sysbench:
[oracle@rac3 sysbench-0.4.12]# ./autogen.sh 
[oracle@rac3 sysbench-0.4.12]# 
[oracle@rac3 sysbench-0.4.12]# ./configure
--prefix=/home/oracle/sysbench 
--with-oracle-libs=/opt/oracle/11.2.0/alifpre/lib 
--with-oracle 
--without-mysql  --可选
make ORA_LIBS=/opt/oracle/11.2.0/alifpre/lib/libclntsh.so && make install 
3 用法
 Usage:
  sysbench [general-options]... --test= [test-options]... command
General options:
  --num-threads=N            number of threads to use [1] 默认为1 
  --max-requests=N           limit for total number of requests [10000] 最大的请求数
  --max-time=N               limit for total execution time in seconds [0] 默认为 0 为无限制
  --forced-shutdown=STRING   达到最大执行时间未结束,则强制关闭。默认是[off]
  --thread-stack-size=SIZE   size of stack per thread [32K]每个线程的stack的大小
  --init-rng=[on|off]        initialize random number generator [off] 
  --test=STRING              测试类型 cpu,fileio,oltp,mutex,memory
  --debug=[on|off]           print more debugging info [off]
  --validate=[on|off]        perform. validation checks where possible [off]
  --help=[on|off]            print help and exit
  --version=[on|off]         print version and exit
Compiled-in tests:
  fileio - File I/O test
  cpu - CPU performance test
  memory - Memory functions speed test
  threads - Threads subsystem performance test
  mutex - Mutex performance test
  oltp - OLTP test
二 测试
前面介绍了sysbench 是一个可以测试 cpu性能,磁盘io性能,调度程序性能,内存分配及传输速度,POSIX线程性能,数据库性能.下面依次介绍
2.1 测试cup,cpu测试主要是进行素数的加法运算,例子中指定了最大的素数为 80000
[root@rac3 kernel]# sysbench --test=cpu --cpu-max-prime=80000 run  
sysbench 0.4.12:  multi-threaded system evaluation benchmark
Running the test with following options:
Number of threads: 1
Doing CPU performance benchmark
Threads started!
Done.
Maximum prime number checked in CPU test: 80000
Test execution summary:
    total time:                          172.6663s
    total number of events:              10000
    total time taken by event execution: 172.6490
    per-request statistics:
         min:                                 17.07ms
         avg:                                 17.26ms
         max:                                 73.72ms
         approx.  95 percentile:              17.62ms
Threads fairness:
    events (avg/stddev):           10000.0000/0.00
    execution time (avg/stddev):   172.6490/0.00
2.2 测试fileio
 选项                      描述                   
--file-num       Number of files to create 默认为128
--file-block-size 读写操作是I/O的操作单位默认为16K
--file-total-size 测试文件的总大小 默认为2G
--file-io-mode   I/O mode. Possible values: sync, async, fastmmap, slowmmap (only if supported by the platform, see above). sync
--file-async-backlog Number of asynchronous operations to queue per thread (only for --file-io-mode=async, see above) 128
--file-extra-flags Additional flags to use with open(2)  
--file-fsync-freq Do fsync() after this number of requests (0 - don not use fsync()) 100
--file-fsync-all Do fsync() after each write operation no
--file-fsync-end Do fsync() at the end of the test yes
--file-fsync-mode Which method to use for synchronization. Possible values: fsync, fdatasync (see above) fsync
--file-merged-requests Merge at most this number of I/O requests if possible (0 - don not merge) 0
--file-rw-ratio  reads/writes ration for combined random read/write test 1.5
--file-test-mode  指定文件测试类型:
seqwr   sequential write
seqrewr sequential rewrite
seqrd   sequential read
rndrd   random read
rndwr   random write
rndrw   combined random read/write
下面的例子 prepare 命令创建了128个文件总共大小为10G ,文件读写模式为随机读写混合方式。run 命令则进行测试,并返回结果,cleanup 删除测试产生的文件!
[root@rac3 ~]# sysbench --num-threads=16 --test=fileio --file-total-size=10G --file-test-mode=rndrw prepare                                                   
sysbench 0.4.12:  multi-threaded system evaluation benchmark
128 files, 81920Kb each, 10240Mb total
Creating files for the test...
[root@rac3 ~]# sysbench --num-threads=16 --test=fileio --file-total-size=10G --file-test-mode=rndrw run

2.6 oltp测试
sysbench 进行oltp 测试的之前,必须创建一个--mysql-db 指定的或者默认的sbtest 数据库,进行prepare的时候,sysbench自动创建一个sbtest表。
[root@rac3 ~]# sysbench --test=oltp --mysql-table-engine=innodb --oltp-table-size=1000000 --mysql-user=root --mysql-host=127.0.0.1  --mysql-db=test prepare
sysbench 0.4.12:  multi-threaded system evaluation benchmark
No DB drivers specified, using mysql
Creating table 'sbtest'...
Creating 1000000 records in table 'sbtest'...  --创建了一个1000000行的表sbtest
进行测试 三种不同的测试模式:semple,complex,nontrx
[root@rac3 ~]# sysbench --test=oltp \
--mysql-table-engine=innodb \
--oltp-table-size=1000000 \
