Question

我正在使用fio进行存储基准测试，fio2gnuplot用于绘制图形，每次运行测试并查看iops的日志文件时，第二个coloumn始终为1，即iops值，并且由于此图形只是一条垂直的直线Y轴。哪个没意义。我试过各种iodepths，ioengines但没有用。我使用任何参数（选项）错了吗？

以下是我的工作档案。

[global]

enter code here

rw=randwrite
size=128m
thread=1
iodepth=2
ioengine=libaio
per_job_logs=0
directory=/home/fio



[job_512]
write_bw_log=logfiles_libaio/fio-test_512
write_iops_log=logfiles_libaio/fio-test_512
write_lat_log=logfiles_libaio/fio-test_512
bs=512b

这是日志文件

1, 1, 0, 512
2, 1, 1, 512
18, 1, 1, 512
19, 1, 0, 512
31, 1, 1, 512
53, 1, 1, 512
55, 1, 1, 512
56, 1, 0, 512
59, 1, 1, 512
63, 1, 1, 512

根据fio手册（man fio），在＆＃34; FIO FILE FORMATS＆＃34;下，它说：

   Fio  supports  a  variety  of log file formats, for logging latencies, bandwidth, and IOPS. The logs
   share a common format, which looks like this:

   time (msec), value, data direction, offset

   Time for the log entry is always in milliseconds. The value logged depends on the type  of  log,  it
   will be one of the following:


   Latency log
          Value is in latency in usecs
   Bandwidth log
          Value is in KB/sec
   IOPS log
          Value is in IOPS

   Data direction is one of the following:


   0      IO is a READ
   1      IO is a WRITE
   2      IO is a TRIM

然而，我认为＆＃39;偏移＆＃39;应该是＆lt; IO尺寸＆＃39;。

所以，在你的带宽情况下，它是：

timestamp(ms), bandwidth(KB/sec), R/W, size
