我使用fio进行存储基准测试，使用fio2gnuplot绘制图形，每次我运行测试并查看iops的日志文件时，第二列总是1，这是iops值，由于这个图形只是一条垂直于Y轴的直线，这没有意义。我尝试了各种iodepth,ioengines，但都没有用。我是否使用了错误的参数(选项)?
下面是我的jobfile.
[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" fio文件格式"下面写着:
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
但是，我认为'offset'应该是'IO size'。
在带宽的情况下，它是:
timestamp(ms), bandwidth(KB/sec), R/W, size
