82 | =head1 DESCRIPTION | ||
83 | |||
84 | This is the place for common routines when writing Nagios plugins. The idea is to make it as | ||
85 | easy as possible for developers to conform to the plugin guidelines | ||
86 | (http://nagiosplug.sourceforge.net/developer-guidelines.html). | ||
87 | |||
88 | =head1 DESIGN | ||
89 | |||
90 | To facilitate object oriented classes, there are multiple perl modules, each reflecting a type of data | ||
91 | (ie, thresholds, ranges, performance). However, a plugin developer does not need to know about the | ||
92 | different types - a "use Nagios::Plugin" should be sufficient. | ||
93 | |||
94 | There is a Nagios::Plugin::Export. This holds all internals variables. You can specify these variables | ||
95 | when use'ing Nagios::Plugin | ||
96 | |||
97 | use Nagios::Plugin qw(%ERRORS) | ||
98 | print $ERRORS{WARNING} # prints 1 | ||
99 | |||
100 | =head1 VERSIONING | ||
101 | |||
102 | Only methods listed in the documentation for each module is public. | ||
103 | |||
104 | These modules are experimental and so the interfaces may change up until Nagios::Plugin | ||
105 | hits version 1.0, but every attempt will be made to make backwards compatible. | ||
106 | |||
107 | =over 4 | ||
108 | |||
109 | =head1 STARTING | ||
110 | |||
111 | =item use Nagios::Plugin qw(%ERRORS) | ||
112 | |||
113 | Imports the %ERRORS hash. This is currently the only symbol that can be imported. | ||
114 | |||
115 | =head1 CLASS METHODS | ||
116 | |||
117 | =item Nagios::Plugin->new( shortname => $$ ) | ||
118 | |||
119 | Initializes a new Nagios::Plugin object. Can specify the shortname here. | ||
120 | |||
121 | =head1 OBJECT METHODS | ||
122 | |||
123 | =item set_thresholds( warning => "10:25", critical => "25:" ) | ||
124 | |||
125 | Sets the thresholds, based on the range specification at | ||
126 | http://nagiosplug.sourceforge.net/developer-guidelines.html#THRESHOLDFORMAT. | ||
127 | Returns a Nagios::Plugin::Threshold object, which can be used to input a value to see which threshold | ||
128 | is crossed. | ||
129 | |||
130 | =item add_perfdata( label => "size", value => $value, uom => "kB", threshold => $threshold ) | ||
131 | |||
132 | Adds to an array a Nagios::Plugin::Performance object with the specified values. | ||
133 | |||
134 | This needs to be done separately to allow multiple perfdata output. | ||
135 | |||
136 | =item die( return_code => $ERRORS{CRITICAL}, message => "Output" ) | ||
137 | |||
138 | Exits the plugin and prints to STDOUT a Nagios plugin compatible output. Exits with the specified | ||
139 | return code. Also prints performance data if any have been added in. | ||
