Individual 2D Graph Each file is plotted in a separate image file with several option
Grouped 2D graph All files are plotted in a single image to ease the comparaison. The same rendering options as per the individual 2D graph are used :
Grouped 3D graph All files are plotted into a single 3D graph. The 3D plotting generates a 'surface' to estimate how close were the performance. A flat surface means a good coherency between traces. A rugged surface means a lack of coherency between traces
Mathemical Plotting
Average graph A bar graph to show the average performance of each file. A green line is added to show the global average performance. This green line helps at understanding how far from the average is every individual file.
Min graph A green line is added to show the global average of minimal performance. This green line helps at understanding how far from the average is every individual file.
Max graph A bar graph to show the maximum performance of each file. A green line is added to show the global average of maximal performance. This green line helps at understanding how far from the average is every individual file.
Standard Deviation A bar graph to show the standard deviation of each file. A green line is added to show the global average of standard deviation. This green line helps at understanding how far from the average is every individual file.
-h or --help The option -h displays help
-p 'pattern' or --pattern 'pattern' A pattern in regexp to select fio input files. Don't forget the simple quotes to avoid shell's interactions
-b or --bandwidth A predefined pattern for selecting *_bw.log files
-i or --iops A predefined pattern for selecting *_iops.log files
-g or --gnuplot Render gnuplot traces before exiting
-o file or --outputfile file The basename for gnuplot traces (set with the pattern if defined)
-d dir or --outputdir dir The directory where gnuplot shall render files.
-t title or --title title The title of the gnuplot traces. Title is set with the block size detected in fio trace
-G type or --Global type Search for 'type' in .global files match by a pattern. Available types are : min, max, avg, stddev. The .global extension is added automatically to the pattern
-m time or --min_time time Only consider data starting from 'time' seconds. Default is 0
-M time or --max_time time Only consider data ending before 'time' seconds. Default is -1 aka nolimit
-v or --verbose Increasing verbosity
-k or --keep Keep all temporary files from gnuplot's output dir
To plot all the traces named like 'host*_read_4k_iops.log' $ fio2gnuplot -p 'host*_read_4k_iops.log' -g
To plot all IO oriented log files from the current directory $ fio2gnuplot -g -i
To plot all Bandwidth oriented log files from the current directory $ fio2gnuplot -g -b
To plot all Bandwidth oriented log files in a directory name 'outdir' $ fio2gnuplot -g -b -d outdir
