我想将 ansible fact 变量的值存储在其他变量中，并且还想检查 fact 变量是否为空

下面是我的代码，我可以在其中打印 ansible_local 事实变量的值，但我希望将该值存储在另一个变量中，比如 xyz。并且还想检查 ansible_local.sj.inventory.as_tag 变量值是否为空

- name: -> Apply common configuration to {{ target }} nodes
  hosts: "{{ target }}"
  gather_facts: True

  user: root

  pre_tasks:
   - setup:
      filter: ansible_local

 tasks:
   - action: debug msg="{{ ansible_local.sj.inventory.as_tag }}"

样品 O/P：

TASK: [debug msg="{{ansible_local.sj.inventory.as_tag}}"]

我有 hostgroups.cfg 文件，其中我有不同的主机，不同的端口号。我想将每个主机的端口号传递给我放置 check_http 命令的 services.cfg 文件。

由于我的不同主机有不同端口号的不同http进程，所以我想直接从hosts.cfg文件传递端口号。可能吗？

以下是我在 hosts 和 services.cfg 文件中的示例条目

主机文件：

        define host{
          use                    abc
          host_name               test
          alias                   /test/
          address                 192.168.0.24
         hostgroups              testgroup
        }

services.cfg 文件

      define service{
         use                             critical-service
         hostgroup_name                  test
         service_description             HTTP
        check_command                   check_http!8080!7!5
     }

commands.cfg 文件

    define command{
        command_name    check_http
        command_line    $USER1$/check_http -H $HOSTADDRESS$ -p          
                     $ARG1$ --url $HOSTALIAS$ -c $ARG2$ -w $ARG3$
    }

当我从浏览器运行 perl CGI 脚本时，它在 apache 错误日志中给出以下错误。它没有得到服务器的响应。当我从命令提示符运行我的脚本时，它工作正常。

我在我的 perl CGI 脚本中使用下面的代码

my %opts = (
    user        => "uname",
    password    => "password",
    ctl_dir     => "/tmp/.libnet-openssh-perl",
    strict_mode => 0,
);

my $ssh = Net::OpenSSH->new("192.168.0.201",%opts,master_opts => ['-vvv', -o => "StrictHostKeyChecking=no" ] );
    $ssh->system("ls /home/sysadmin/") or
     die "remote command failed: " . $ssh->error;

错误日志：
