Collecting error messages generated during fact gathering

Get Help
1

I’m writing a playbook to install a software on 5000 machines. The hosts are added to a group dynamically and the later jobs are running on each host in the group. My question is, during the fact gathering process, if some of the hosts are not responding or something wrong happened which caused the fact gathering failed. I want to collect the error messages and use these messages in the later plays.

I’m wondering how to implement it. An example code would be very appreciated.

Hi,

# hosts
[all]
localhost ansible_connection=local
8.8.8.8


# test.yml
---
- hosts: all
  gather_facts: false
  tasks:
    - name: Gather
      ansible.builtin.setup:
      ignore_errors: true
      ignore_unreachable: true
      register: _g

    - name: Debug failed
      ansible.builtin.debug:
        var: _g
      when: (ansible_facts | length) == 0

Running ansible-playbook -i hosts test.yml yields:

PLAY [all] ***********************************************************************************************************

        "unreachable": true
    }
}

localhost                  : ok=1    changed=0    unreachable=0    failed=0    skipped=1    rescued=0    ignored=0

I hope this helps
