NAME

Monitoring::Generator::TestConfig - generate monitoring configurations (nagios/icinga/shinken)

SYNOPSIS

use Monitoring::Generator::TestConfig;
my $ngt = Monitoring::Generator::TestConfig->new( 'output_dir' => '/tmp/test_monitoring' );
$ngt->create();

DESCRIPTION

This modul generates test configurations for your monitoring. This can be useful if you want for doing load tests or testing addons and plugins.

METHODS

create

create()

generates and writes the configuration
Returns true on success or undef on errors.

EXAMPLE

OMD Users

Using OMD makes generating test configs really easy:

#> create site test
#> su - test
OMD[test]:~$ cpan
...
Would you like me to configure as much as possible automatically? [yes] <enter>
...
cpan[1]> install Monitoring::Generator::TestConfig
...
cpan[2]> exit
OMD[test]:~$ ./local/lib/perl5/bin/create_monitoring_test_config.pl

After the first installation, configuration can be adjusted in the recreate.pl in your SITE directory.

Sample Script

Create a sample config with manually overriden host/service settings:

use Monitoring::Generator::TestConfig;
my $mgt = Monitoring::Generator::TestConfig->new(
                    'output_dir'                => '/tmp/test-conf',
                    'verbose'                   => 1,
