| 100 | =head1 NAME | ||
| 101 | |||
| 102 | Monitoring::Plugin::Config - read nagios plugin .ini style config files | ||
| 103 | |||
| 104 | =head1 SYNOPSIS | ||
| 105 | |||
| 106 | # Read given nagios plugin config file | ||
| 107 | $Config = Monitoring::Plugin::Config->read( '/etc/nagios/plugins.ini' ); | ||
| 108 | |||
| 109 | # Search for and read default nagios plugin config file | ||
| 110 | $Config = Monitoring::Plugin::Config->read(); | ||
| 111 | |||
| 112 | # Access sections and properties (returns scalars or arrayrefs) | ||
| 113 | $rootproperty = $Config->{_}->{rootproperty}; | ||
| 114 | $one = $Config->{section}->{one}; | ||
| 115 | $Foo = $Config->{section}->{Foo}; | ||
| 116 | |||
| 117 | =head1 DESCRIPTION | ||
| 118 | |||
| 119 | Monitoring::Plugin::Config is a subclass of the excellent Config::Tiny, | ||
| 120 | with the following changes: | ||
| 121 | |||
| 122 | =over 4 | ||
| 123 | |||
| 124 | =item | ||
| 125 | |||
| 126 | Repeated keys are allowed within sections, returning lists instead of scalars | ||
| 127 | |||
| 128 | =item | ||
| 129 | |||
| 130 | Write functionality has been removed i.e. access is read only | ||
| 131 | |||
| 132 | =item | ||
| 133 | |||
| 134 | Monitoring::Plugin::Config searches for a default nagios plugins file if no explicit | ||
| 135 | filename is given to C<read()>. The current standard locations checked are: | ||
| 136 | |||
| 137 | =over 4 | ||
| 138 | |||
| 139 | =item /etc/nagios/plugins.ini | ||
| 140 | |||
| 141 | =item /usr/local/nagios/etc/plugins.ini | ||
| 142 | |||
| 143 | =item /usr/local/etc/nagios /etc/opt/nagios/plugins.ini | ||
| 144 | |||
| 145 | =item /etc/nagios-plugins.ini | ||
| 146 | |||
| 147 | =item /usr/local/etc/nagios-plugins.ini | ||
| 148 | |||
| 149 | =item /etc/opt/nagios-plugins.ini | ||
| 150 | |||
| 151 | =back | ||
| 152 | |||
| 153 | To use a custom location, set a C<NAGIOS_CONFIG_PATH> environment variable | ||
| 154 | to the set of directories that should be checked. The first C<plugins.ini> or | ||
| 155 | C<nagios-plugins.ini> file found will be used. | ||
| 156 | |||
