1 | NAME |
2 | fio2gnuplot - Render fio's output files with gnuplot | |
3 | SYNOPSIS | |
4 | fio2gnuplot [-ghbiodvk] [-t title] [-o outputfile] | |
5 | [-d output_dir] [-p pattern] | |
6 | [-G type] [-m min_time] [-M max_time] | |
7 | ||
8 | DESCRIPTION | |
9 | fio2gnuplot analyze a set of fio's log files to turn them into a set of graphical traces using gnuplot tool. | |
10 | Several flavor of plotting are produced | |
11 | ||
12 | Individual 2D Graph | |
13 | Each file is plotted in a separate image file with several option | |
14 | - raw : Plot the exact reported performance. This plotting could be difficult to read | |
15 | - smooth :a smoother version of the raw print | |
16 | Using csplines option of gnuplot, the rendering is | |
17 | filtered to get an easier to read graph. | |
18 | - trend : an even smoother version of the raw print to get trends | |
19 | Bezier's curves makes much more filtered plots | |
20 | The resulting graph helps at understanding trends. | |
21 | ||
22 | Grouped 2D graph | |
23 | All files are plotted in a single image to ease the comparaison. The same rendering options as per the individual 2D graph are used : | |
24 | - raw | |
25 | - smooth | |
26 | - trend | |
27 | ||
28 | Grouped 3D graph | |
29 | All files are plotted into a single 3D graph. | |
30 | The 3D plotting generates a 'surface' to estimate how close were | |
31 | the performance. | |
32 | A flat surface means a good coherency between traces. | |
33 | A rugged surface means a lack of coherency between traces | |
34 | ||
35 | Mathemical Plotting | |
36 | Average graph | |
37 | A bar graph to show the average performance of each file. | |
38 | A green line is added to show the global average performance. | |
39 | This green line helps at understanding how far from the average is | |
40 | every individual file. | |
41 | ||
42 | Min graph | |
43 | A green line is added to show the global average of minimal performance. | |
44 | This green line helps at understanding how far from the average is | |
45 | every individual file. | |
46 | ||
47 | Max graph | |
48 | A bar graph to show the maximum performance of each file. | |
49 | A green line is added to show the global average of maximal performance. | |
50 | This green line helps at understanding how far from the average is | |
51 | every individual file. | |
52 | ||
53 | Standard Deviation | |
54 | A bar graph to show the standard deviation of each file. | |
55 | A green line is added to show the global average of standard deviation. | |
56 | This green line helps at understanding how far from the average is | |
57 | every individual file. | |
58 | ||
59 | OPTIONS | |
60 | -h or --help | |
61 | The option -h displays help | |
62 | ||
63 | -p 'pattern' or --pattern 'pattern' | |
64 | A pattern in regexp to select fio input files. | |
65 | Don't forget the simple quotes to avoid shell's interactions | |
66 | ||
67 | -b or --bandwidth | |
68 | A predefined pattern for selecting *_bw.log files | |
69 | ||
70 | -i or --iops | |
71 | A predefined pattern for selecting *_iops.log files | |
72 | ||
73 | -g or --gnuplot | |
74 | Render gnuplot traces before exiting | |
75 | ||
76 | -o file or --outputfile file | |
77 | The basename for gnuplot traces (set with the pattern if defined) | |
78 | ||
79 | -d dir or --outputdir dir | |
80 | The directory where gnuplot shall render files. | |
81 | ||
82 | -t title or --title title | |
83 | The title of the gnuplot traces. | |
84 | Title is set with the block size detected in fio trace | |
85 | ||
86 | -G type or --Global type | |
87 | Search for 'type' in .global files match by a pattern. | |
88 | Available types are : min, max, avg, stddev. | |
89 | The .global extension is added automatically to the pattern | |
90 | ||
91 | -m time or --min_time time | |
92 | Only consider data starting from 'time' seconds. Default is 0 | |
93 | ||
94 | -M time or --max_time time | |
95 | Only consider data ending before 'time' seconds. Default is -1 aka nolimit | |
96 | ||
97 | -v or --verbose | |
98 | Increasing verbosity | |
99 | ||
100 | -k or --keep | |
101 | Keep all temporary files from gnuplot's output dir | |
102 | ||
103 | EXAMPLE | |
104 | To plot all the traces named like 'host*_read_4k_iops.log' | |
105 | $ fio2gnuplot -p 'host*_read_4k_iops.log' -g | |
106 | ||
107 | To plot all IO oriented log files from the current directory | |
108 | $ fio2gnuplot -g -i | |
109 | ||
110 | To plot all Bandwidth oriented log files from the current directory | |
111 | $ fio2gnuplot -g -b | |
112 | ||
113 | To plot all Bandwidth oriented log files in a directory name 'outdir' | |
114 | $ fio2gnuplot -g -b -d outdir | |
