We have a dual Nagios server setup. One is setup for internal server monitoring on our LAN, while the second Nagios server is hosted externally and is used for external checks only such as URL and ping checks form the WAN side.
I was wondering if there is any way to setup cross dependencies... (1 Reply)

Nagios::Object(3pm) User Contributed Perl Documentation Nagios::Object(3pm)
NAME
Nagios::Object - Creates perl objects to represent Nagios objects
DESCRIPTION
This module contains the code for creating perl objects to represent any of the Nagios objects. All of the perl classes are auto-generated
at compile-time, so it's pretty trivial to add new attributes or even entire objects. The following is a list of currently supported
classes:
Nagios::TimePeriod
Nagios::Command
Nagios::Contact
Nagios::ContactGroup
Nagios::Host
Nagios::Service
Nagios::HostGroup
Nagios::ServiceEscalation
Nagios::HostDependency
Nagios::HostEscalation
Nagios::HostGroupEscalation
Nagios::ServiceDependency
-- next two are for status.dat in Nagios 2.x
Nagios::Info
Nagios::Program
EXAMPLE
use Nagios::Object;
my $generic_host = Nagios::Host->new(
register => 0,
parents => undef,
check_command => $some_command,
max_check_attempts => 3,
checks_enabled => 1,
event_handler => $some_command,
event_handler_enabled => 0,
low_flap_threshold => 0,
high_flap_threshold => 0,
flap_detection_enabled => 0,
process_perf_data => 1,
retain_status_information => 1,
retain_nonstatus_information => 1,
notification_interval => $timeperiod,
notification_options => [qw(d u r)],
notifications_enabled => 1,
stalking_options => [qw(o d u)]
);
# this will automatically 'use' $generic_host
my $localhost = $generic_host->new(
host_name => "localhost",
alias => "Loopback",
address => "127.0.0.1"
);
my $hostname = $localhost->host_name();
printf "max check attempts for $hostname is %s.
",
$localhost->max_check_attempts;
$localhost->set_event_handler(
Nagios::Command->new(
command_name => "new_event_handler",
command_line => "/bin/true"
)
);
METHODS
new()
Create a new object of one of the types listed above.
Calling new() on an existing object will use the LHS object as the template for the object being created. This is mainly useful for
creating objects without involving Nagios::Object::Config (like in the test suite).
Nagios::Host->new( ... );
dump()
Output a Nagios define { } block from an object. This is still EXPERIMENTAL, but may eventually be robust enough to use for a
configuration GUI. Passing in a single true argument will tell it to flatten the object inheritance on dump.
print $object->dump();
print $object->dump(1); # flatten
name()
This method is common to all classes created by this module. It should always return the textual name for an object. It is used
internally by the Nagios::Object modules to allow polymorphism (which is what makes this module so compact). This is the only way to
retrieve the name of a template, since they are identified by their "name" field.
my $svc_desc = $service->name;
my $hostname = $host->name;
Which is just short for:
my $svc_desc = $service->service_description;
my $hostname = $service->host_name;
register()
Returns true/undef to indicate whether the calling object is registerable or not.
if ( $object->register ) { print $object->name, " is registerable." }
has_attribute()
Returns true/undef to indicate whether the calling object has the attribute specified as the only argument.
# check to see if $object has attribute "command_line"
die if ( !$object->has_attribute("command_line") );
list_attributes()
Returns a list of valid attributes for the calling object.
my @host_attributes = $host->list_attributes();
attribute_type()
Returns the type of data expected by the object's set_ method for the given attribute. For some fields like notification_options, it
may return "char_flag."
For "name" attributes, it will simply return whatever %setup_data contains.
This method needs some TLC ...
my $type = $host->attribute_type("notification_period");
attribute_is_list()
Returns true if the attribute is supposed to be a list (ARRAYREF).
if ( $object->attribute_is_list("members") ) {
$object->set_members( [$member] );
} else {
$object->set_members( $member );
}
