NAME

SYNOPSIS

9         use Messaging::Message::Generator;
10
11         # create the generator
12         $mg = Messaging::Message::Generator->new(
13             "text"                 => "0-1",
14             "body-length"          => "0-1000",
15             "body-entropy"         => "1-4",
16             "header-count"         => "2^6",
17             "header-name-length"   => "10-20",
18             "header-name-entropy"  => "1-2",
19             "header-name-prefix"   => "rnd-",
20             "header-value-length"  => "20-40",
21             "header-value-entropy" => "0-3",
22         );
23
24         # use it to generate 10 messages
25         foreach (1 .. 10) {
26             $msg = $mg->message();
27             ... do something with it ...
28         }

DESCRIPTION

31       This module provides a versatile message generator that can be useful
32       for stress testing or benchmarking messaging brokers or libraries.
33

METHODS

35       The following methods are available:
36
37       new([OPTIONS])
38           return a new Messaging::Message::Generator object (class method)
39
40       message()
41           return a newly generated Messaging::Message object
42

OPTIONS

44       When creating a message generator, the following options can be given:
45
46       text
47           integer specifying if the body is text string (as opposed to binary
48           string) or not; supported values are 0 (never text), 1 (always
49           text) or "0-1" (randomly text or not)
50
51       body-length
52           integer specifying the length of the body
53
54       body-entropy
55           integer specifying the entropy of the body
56
57       header-count
58           integer specifying the number of header fields
59
60       header-name-prefix
61           string to prepend to each header field name
62
63       header-name-length
64           integer specifying the length of each header field name (prefix not
65           included)
66
67       header-name-entropy
68           integer specifying the entropy of each header field name
69
70       header-value-prefix
71           string to prepend to each header field value
72
73       header-value-length
74           integer specifying the length of each header field value (prefix
75           not included)
76
77       header-value-entropy
78           integer specifying the entropy of each header field value
79
80       All the options default to 0 or the empty string.
81
82       All the integer options can be given either:
83
84       •   a positive integer "X", meaning exactly this value
85
86       •   a "X-Y" range, meaning a discrete uniform distribution between the
87           two given integers, bounds included
88
89       •   a "X^Y" range, meaning a pseudo normal distribution between the two
90           given integers, bounds included
91
92       All the entropy options interpret their integer value this way:
93
94       •   0 means a single character, repeated
95
96       •   1 means hexadecimal characters
97
98       •   2 means Base64 characters (with "-" instead of "/" and "_" instead
99           od "+")
100
101       •   3 means printable 7-bit ASCII characters
102
103       •   4 means random characters (including Unicode, except for binary
104           bodies)
105
