1 Linux常見(jiàn)基準(zhǔn)測(cè)試工具
FIO
Sysbench
Phoronix Test Suite (moved to it's own page)
IOzone
Ioping
UnixBench
Google's Perfkit Benchmarker
2 FIO
fio算是比較老的io測(cè)試工具了，作者是Jens Axboe。
主頁(yè)https://www.thomas-krenn.com/en/wiki/Fio
fio的安裝
我的測(cè)試環(huán)境有centos7 redhat5因此要下載兩個(gè)版本的fio包
redhat5版本的需要去歸檔站點(diǎn)去下載
http://archives.fedoraproject.org/pub/archive/epel/
下載后的安裝 rpm -ivh fio-1.57-1.el5.x86_64.rpm
centos7則可以去很多鏡像站點(diǎn)下載，站點(diǎn)列表可以查詢
https://admin.fedoraproject.org/mirrormanager/mirrors/EPEL
如果配置了epel的yum源，直接yum install -y fio
fio測(cè)試選項(xiàng)和例子
示例 使用fio測(cè)試磁盤(pán)的隨機(jī)寫(xiě)
fio --name=randwrite --ioengine=libaio --iodepth=1 --rw=randwrite --bs=4k \
--direct=0 --size=512M --numjobs=8 --runtime=240 --group_reporting
--rw=randwrite指定隨機(jī)寫(xiě)
--direct=0指定使用buffered IO還是direct IO。如果使用buffer，注意總大小不要超過(guò)物理內(nèi)存
--numjobs=8啟動(dòng)8個(gè)進(jìn)程
--size=512M每個(gè)進(jìn)程寫(xiě)512M
--group_reporting 將多個(gè)進(jìn)程的統(tǒng)計(jì)結(jié)果進(jìn)行聚合，更易閱讀
--runtime=240持續(xù)運(yùn)行時(shí)間4分鐘
--bs=4k --blocksize=4k (default)
--ioengine=libaio可用的io引擎可以使用 fio --enghelp查看(fio-2.2.8)
--iodepth=1缺省 測(cè)試ssd磁盤(pán)時(shí)，可以擴(kuò)大到32，通常4就夠了
The iodepth option defines the amount of IO units that will continue to hammer a file with requests during the test.
避免使用buffer的方法是指定--direct=1或者使用比物理內(nèi)存大一倍的寫(xiě)文件
fio結(jié)果的重點(diǎn)關(guān)注項(xiàng)目：
iops=1416 iops = 1416
95.00th=[ 2] 95%的IO在2毫秒完成
util=99.62% 設(shè)備繁忙程度
示例 使用fio測(cè)試磁盤(pán)的隨機(jī)讀
fio --name=randread --ioengine=libaio --iodepth=16 --rw=randread --bs=4k \
--direct=0 --size=512M --numjobs=8 --runtime=240 --group_reporting
fio幫助
man fio
fio -h
fio -v
fio命令行中寫(xiě)上選項(xiàng)，也可以將命令行選項(xiàng)寫(xiě)入一個(gè)參數(shù)文件job file中
fio安裝后，自帶了一些樣例

fio輸出結(jié)果的一些注釋
io Number of megabytes of I/O performed.
bw Average data rate (bandwidth).
runt Threads run time.
slat Submission latency minimum, maximum, average and standard deviation. This
is the time it took to submit the I/O.
clat Completion latency minimum, maximum, average and standard deviation. This
is the time between submission and completion.
bw Bandwidth minimum, maximum, percentage of aggregate bandwidth received, average and standard deviation.
The group statistics show:
io Number of megabytes I/O performed.
aggrb Aggregate bandwidth of threads in the group.
minb Minimum average bandwidth a thread saw.
maxb Maximum average bandwidth a thread saw.
mint Shortest runtime of threads in the group.
maxt Longest runtime of threads in the group.
Finally, disk statistics are printed with reads first:
ios Number of I/Os performed by all groups.
merge Number of merges in the I/O scheduler.
ticks Number of ticks we kept the disk busy.
io_queue
Total time spent in the disk queue.
util Disk utilization.

Phoronix測(cè)試套件簡(jiǎn)稱pts,從官網(wǎng)http://phoronix-test-suite.com/?k=downloads下載安裝包 phoronix-test-suite-7.0.1.tar.gz
pts的安裝依賴php-cli等多個(gè)包
tar xvf phoronix-test-suite_6.2.2.tar.gz
cd phoronix-test-suite/

/usr/bin/phoronix-test-suite list-available-tests
phoronix-test-suite info pts/disk
phoronix-test-suite install pts/iozon
phoronix-test-suite install pts/disk
pts/disk包括了fio iozone aio-stress等等多個(gè)工具，pts太過(guò)龐大，install時(shí)因?yàn)榫W(wǎng)速原因，耗時(shí)較長(zhǎng)。這里只使用一個(gè)iozone做個(gè)測(cè)試。
