木偶检查是否Nagios的资源存在

问题描述 投票:2回答:2

我有一个包含一个安装在以相同的方式3级的服务器的应用程序的模块的傀儡3.8.5环境。

在模块我有下面的类

class app::monitoring {

include nrpe
include nagios::export

@@nagios_contactgroup:{ 'APP':
  ensure                        =>  present,
  alias                         => 'APP Developer',
  members                       => 'user1, user2',
  target                        => '/etc/nagios/conf.d/contacts.cfg',
  }

@@nagios_contact {'user1':
  ensure                        => present,
  alias                         => 'user1',
  email                         => '[email protected]',
  service_notification_period   => 'workhours',
  host_notification_period      => 'workhours',
  service_notification_commands => 'notify-service-by-email',
  host_notification_commands    => 'notify-service-by-email',
  target                        => '/etc/nagios/conf.d/contacts.cfg',
  }

@@nagios_service { 'check_app_http_${fqdn}':
  ensure                        => present,
  use                           => "local-service',
  host_name                     => $fqdn,
  service_description           => 'Check App - port 8000',
  check_command                 => 'check_http_app!8000',
  notifications_enabled         => '1',
  target                        => '/etc/nagios/conf.d/service.cfg',
  }

  @@nagios_command {"check_http_app":
    ensure                      => present,
    command_line                => '/usr/lib64/nagios/plugins/check_http -H $HOSTADDRESS$ -p $ARG1$',
    target                      => '/etc/nagios/conf.d/commands.cfg',
    }
  }

正如预期的正确所有的作品,当木偶在每台服务器上运行,但失败并重复输入错误当傀儡的Nagios服务器上运行。有没有办法改变的代码,这样,如果/当这是在随后的服务器上运行,我没有得到一个重复的资源错误?

目前,我手动创建

  • nagios_contactgroup,
  • nagios_contact和
  • nagios_command

在/ etc / nagios的/对象的条目,使他们有效地被硬编码到Nagios的。我宁愿要能够完全重建的nagios无需人工干预的能力。

我们遇到了同样的问题,有一个解决办法想出了 - 周围nagios_command等功能的包装:

define ournagios::nagios_command (
  $nagios_title, 
  ... # all other built-in parameters
){
  # some custom code for changing parameters
  # Note that any resource creation here must be
  # wrapped with `if ! defined()`

  if ! defined(Nagios_command["$nagios_title"]) {
    nagios_command { $nagios_title:
      command_name => $command_name,
      ensure       => $ensure,
      command_line => $command_line,
      group        => $group,
      mode         => $mode,
      owner        => $owner,
      poller_tag   => $poller_tag,
      provider     => $provider,
      target       => $_target,
      use          => $use,
    }
  }
}

我们用这样的:

@@ournagios::nagios_command { "check_dns-${::hostname}":
  nagios_title => "check_dns",
  command_line => '$USER1$/check_dns -s \'$HOSTADDRESS$\' -H \'$ARG1$\' -a \'$ARG2$\' -w \'$ARG3$\' -c \'$ARG4$\'',
}

ournagios::nagios_check资源被创建,但他们都有不同的名称和实际nagios_command只创建一次。

你必须确保你有@@出口资源具有唯一的名称,这样,当它们在Nagios的服务器上收集你没有得到重复的资源。
