0 linux io benchmarking storage
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,第二列始终为 1,即 iops 值,并且由于此图形只是一条垂直于 Y 轴的直线。这没有任何意义。我尝试了各种 iodepths、ioengines 但没有用。我使用任何参数(选项)错误吗?
以下是我的工作档案。

根据 fio 手册(man fio),在“FIO 文件格式”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

但是,我认为“偏移量”应该是“IO 大小”。
因此,在您的带宽情况下,它是:
timestamp(ms), bandwidth(KB/sec), R/W, size
