17 \fBfio2gnuplot\fP analyze a set of fio's log files to turn them into a set of graphical traces using gnuplot tool.
18 Several flavor of plotting are produced
22 Each file is plotted in a separate image file with several option
25 raw : Plot the exact reported performance. This plotting could be difficult to read
27 smooth :a smoother version of the raw print
28 Using csplines option of gnuplot, the rendering is
29 filtered to get an easier to read graph.
31 trend : an even smoother version of the raw print to get trends
32 Bezier's curves makes much more filtered plots
33 The resulting graph helps at understanding trends.
38 All files are plotted in a single image to ease the comparaison. The same rendering options as per the individual 2D graph are used :
50 All files are plotted into a single 3D graph.
51 The 3D plotting generates a 'surface' to estimate how close were
53 A flat surface means a good coherency between traces.
54 A rugged surface means a lack of coherency between traces
62 A bar graph to show the average performance of each file.
63 A green line is added to show the global average performance.
64 This green line helps at understanding how far from the average is
65 every individual file.
69 A green line is added to show the global average of minimal performance.
70 This green line helps at understanding how far from the average is
71 every individual file.
75 A bar graph to show the maximum performance of each file.
76 A green line is added to show the global average of maximal performance.
77 This green line helps at understanding how far from the average is
78 every individual file.
82 A bar graph to show the standard deviation of each file.
83 A green line is added to show the global average of standard deviation.
84 This green line helps at understanding how far from the average is
85 every individual file.
89 \fB-h\fP or \fB--help\fP
90 The option \fB-h\fP displays help
93 \fB-p\fP '\fIpattern\fP' or --\fIpattern\fP '\fIpattern\fP'
94 A \fIpattern\fP in regexp to select fio input files.
95 Don't forget the simple quotes to avoid shell's interactions
98 \fB-b\fP or \fB--bandwidth\fP
99 A predefined \fIpattern\fP for selecting *_bw.log files
102 \fB-i\fP or \fB--iops\fP
103 A predefined \fIpattern\fP for selecting *_iops.log files
106 \fB-g\fP or \fB--gnuplot\fP
107 Render gnuplot traces before exiting
110 \fB-o\fP file or --\fIoutputfile\fP file
111 The basename for gnuplot traces (set with the \fIpattern\fP if defined)
114 \fB-d\fP dir or \fB--outputdir\fP dir
115 The directory where gnuplot shall render files.
118 \fB-t\fP \fItitle\fP or --\fItitle\fP \fItitle\fP
119 The \fItitle\fP of the gnuplot traces.
120 Title is set with the block size detected in fio trace
123 \fB-G\fP \fItype\fP or \fB--Global\fP \fItype\fP
124 Search for '\fItype\fP' in .global files match by a \fIpattern\fP.
125 Available types are : min, max, avg, stddev.
126 The .global extension is added automatically to the \fIpattern\fP
129 \fB-m\fP time or --\fImin_time\fP time
130 Only consider data starting from 'time' seconds. Default is 0
133 \fB-M\fP time or --\fImax_time\fP time
134 Only consider data ending before 'time' seconds. Default is \fB-1\fP aka nolimit
137 \fB-v\fP or \fB--verbose\fP
141 \fB-k\fP or \fB--keep\fP
142 Keep all temporary files from gnuplot's output dir
146 To plot all the traces named like 'host*_read_4k_iops.log'
147 $ \fBfio2gnuplot\fP \fB-p\fP 'host*_read_4k_iops.log' \fB-g\fP
150 To plot all IO oriented log files from the current directory
151 $ \fBfio2gnuplot\fP \fB-g\fP \fB-i\fP
154 To plot all Bandwidth oriented log files from the current directory
155 $ \fBfio2gnuplot\fP \fB-g\fP \fB-b\fP
158 To plot all Bandwidth oriented log files in a directory name 'outdir'
159 $ \fBfio2gnuplot\fP \fB-g\fP \fB-b\fP \fB-d\fP outdir
