Nagios::Service|Host|Program::StatusDESCRIPTION
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(),"\n"; $log->update(); print "status of localhost is now ",$localhost->status(),"\n"; # 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.
