Nagios::StatusLog(3pm) User Contributed Perl Documentation Nagios::StatusLog(3pm)
NAME
Nagios::StatusLog, Nagios::(Service|Host|Program)::Status - Perl objects to represent the Nagios status file
DESCRIPTION
Reads the Nagios status log and returns ::Status objects that can be used to get status information about a host. For Nagios version 2.x
logs, pass in the Version => 2.0 parameter to new(). And similarly, pass in the Version => 3.0 parameter to new() for Nagios version 3.x
logs.
my $log = Nagios::StatusLog->new(
Filename => "/var/opt/nagios/status.log",
Version => 1.0
);
$localhost = $log->host( "localhost" );
print "status of localhost is now ",$localhost->status(),"
";
$log->update();
print "status of localhost is now ",$localhost->status(),"
";
# for Nagios v2.0
my $log = Nagios::StatusLog->new(
Filename => "/var/cache/nagios2/status.dat",
Version => 2.0
);
# for Nagios v3.0
my $log = Nagios::StatusLog->new(
Filename => "/var/cache/nagios3/status.dat",
Version => 3.0
);
METHODS
new()
Create a new Nagios::StatusLog instance. The object will be initialized for you (using $self->update()).
Nagios::StatusLog->new( "/var/opt/nagios/status.log" );
update()
Updates the internal data structures from the logfile.
$log->update();
service()
Returns a Nagios::Service::Status object. Input arguments can be a host_name and description list, or a Nagios::Service object.
my $svc_stat = $log->service( "localhost", "SSH" );
my $svc_stat = $log->service( $localhost_ssh_svc_object );
Nagios::Service::Status has the following accessor methods (For V1):

STRUCTURE
This module contains 4 packages: Nagios::StatusLog, Nagios::Host::Status, Nagios::Service::Status, and Nagios::Program::Status. The latter
3 of them are mostly generated at compile-time in the BEGIN block. The accessor methods are real subroutines, not AUTOLOAD, so making a
ton of calls to this module should be fairly quick. Also, update() is set up to only do what it says - updating from a fresh logfile
should not invalidate your existing ::Status objects.
