NAME

Nagios::Config - Parse Nagios configuration files

SYNOPSIS

  use Nagios::Config ;
  my $nc = new Nagios::Config("/usr/local/nagios/etc/nagios.cfg") ;
  foreach my $object ($nc->get_objects('host')){
    print $object->get('host_name') . "\n" ;
  }

DESCRIPTION

Nagios::Config parses the Nagios configuration files in order to extract all information about nagios.cfg, resource.cfg and template-based objects. All template values are merged recursively, meaning that each object has all its attributes present, even those that were defined in templates.

Note: Nagios::Config assumes that your Nagios configuration is valid and may react unexpectedly if it is not. Please check your configuration using the "nagios -v" command prior to using Nagios::Config on it.

CONSTRUCTOR

new ([FILE])

Creates a Nagios::Config, which will parse the contents of FILE assuming it is a Nagios Main Configuration File. FILE can be a file name or a reference to an already opened filehandle. If FILE is false, it will default to "/usr/local/nagios/etc/nagios.cfg"

METHODS

get_object_types ()

Returns a list of all the object types that where encountered during the parse.

Ex: my @types = $nc->get_object_types() ;

get_object_files ()

Returns a list of all the template object files (as Nagios::Config::ObjectFile objects) that where parsed.

Ex: my @files = $nc->get_object_files() ;

get_objects ([TYPE])

Returns a list of all the objects of type TYPE that where found during the parse. Each of these objects will be blessed in the Nagios::Config::Object::TYPE package, which inherits from Nagios::Config::Object.

Ex: my @hosts = $nc->get_objects('host') ;

get_object_hash ([TYPE], [KEY])

Returns a hash of all the objects of type TYPE that where found during the parse, using attribute KEY as the hash key. Make sure that the value of KEY is unique for each object, or else you will not get all the objects in the hash. Each of these objects will be blessed in the Nagios::Config::Object::TYPE package, which inherits from Nagios::Config::Object.

Ex: my %hosts = $nc->get_object_hash('host', 'host_name') ;

find_objects ([TYPE], [ATTR], [QUERY], [SPLIT])

Returns a list of all the objects of type TYPE that where found during the parse, where ATTR "matches" QUERY. QUERY can be a regular expression (i.e. qr/.../) or a scalar. If SPLIT is true, the values will be split on /\s*,\s*/ and each of the resulting values will be compared separately. Also, if the value of the ATTR is '*', the object is returned regardless of the value of QUERY. Each of these objects will be blessed in the Nagios::Config::Object::TYPE package, which inherits from Nagios::Config::Object.

Ex: my %my_host_services = $nc->get_object_hash('service', 'host_name', 'my_host', 1) ;

get_nagios_cfg ()

Returns the Nagios::Config::File object corresponding to nagios.cfg.

get_resource_cfg ()

Returns the Nagios::Config::File object corresponding to resource.cfg.
