Love this, but a question: the possible chart types are hardcoded, right? E.g., comparing by iodepth or numjobs.

How about if I want to vary other parameters, e.g., see how IOPS vary with block size?

I just saw the -C option, it may be what I want...

Will close this if so.

It may be that the compare option is not flexible enough to display blocksizes on the axes, unfortunately the metrics are fixed. It makes total sense to allow Fio users to plot arbitrary metricsz

Hello Travis, You can use -C to compare IOPS and latency for different block sizes.

Hello Louwrentius, I want to compare bandwidth for different block sizes. looks like -C option only supports IOPS and latency. -t option can specify bandwidth, but it isn't compatible with -C. Is there an way to do this?

travisdowns commented 2 years ago

Yeah it turns out -C wasn't what I wanted.

Because the bench-fio tool creates folders for each block size tested, it's now possible to do a -C compare graph and adjust the label such that the block size is included.

~/projects/fio-plot/bin/fio-plot -i PMEM0_1_RR_15M/pmem0.1/1k/ PMEM0_1_RR_15M/pmem0.1/4k/ PMEM0_1_RR_15M/pmem0.1/8k/ -T "Test" -C -r randread --xlabel-parent 0

However, comparing bandwidth with particular block-sizes can't be done, only be inferred. The IOPS and Latency columns are still hard-coded.
