Possibility to change attributes of existing hosts

[L4aShadow]

Hi,

I wonder if Ansible collection provides the ability to change attributes (tags) only on existing hosts.

I am using the following playbook:

- name: "Sync attribute to CheckMK"
    host:
      server_url: "{{ checkmk_agent_test_server_url }}"
      site: "{{ checkmk_agent_test_site }}"
      automation_user: '{{ checkmk_agent_user }}'
      automation_secret: '{{ checkmk_agent_secret }}'
      name: "{{ inventory_hostname }}"
      update_attributes:
        'tag_backup: "{{ hostvars[inventory_hostname]['cBackup'] }}"
      state: "present"

Works without problem for existing hosts. But if a host does not exist anything in CheckMK, the task creates the host. I was hoping that 'state: "present"' would make this change only take effect for existing hosts. The others are ignored.

But in the script 'host.py' I see from line 349 that the attributes are only changed if "state == "present" and current_state == "present"". If "state == "present" and current_state == "absent"" (line 384) the host is always created with the attributes.

Am I right that with Ansible I have no way to skip attribute changes if the host is not present?

For your information, the list of hosts comes from a CMDB. Therefore it is possible that hosts are queried but not monitored in CheckMK.

Thanks already

Hi @L4aShadow and my apologies for the late response!
We are not monitoring discussions as closely as the issues, as this is more a place for announcements and less important discussions.

We did some work on the host module, so if you are experiencing issues with the latest version still, I would ask you to open an issue, so we can inspect the situation more closely.
