You probably want to use ansible.builtin.stat which will tell you both whether the file exists (find doesn't find it if it doesn't) and what size it is.
- name: Get stat for /var/log/messages
ansible.builtin.stat:
path: /var/log/messages
register: messages_files
- name: What to do about missing /var/log/messages?
ansible.builtin.debug:
msg: '{{ inventory_hostname }} has no /var/log/messages. Now what?'
when: not messages_files.stat.exists
- name: Restart syslog if /var/log/messages is zero-length
ansible.builtin.service:
name: syslog
state: restarted
when: messages_files.stat.exists and messages_files.stat.size == 0
There's no need to start another play to do the service restarts.

Well, the set_fact is supposed to only register or select anything where the size parameter of the files attributes is 0. The ones that are printing just [] don't fit that criteria, and therefore, shouldn't be included in the debug output. Yet they are, so that's what I'm trying to fix/clean up first.Thanks, HarryOn Wednesday, April 24, 2024 at 3:51:55 PM UTC-4 dulh...@mailbox.org wrote:1) How can I NOT print what server2 is printing/showing?I'd say add a when clause to the task, like: - name: Print results ansible.builtin.debug: msg: "{{ zero }}" when: "some condition here" so the print only happens when the condition is met. The condition might be some value from the message_files variable Or maybe something like: when: meages_files.ssfiles | selectattr('size', '==', 0) not sure about that though because I don't understand really what meages_files.ssfiles | selectattr('size', '==', 0) does On 4/24/24 9:26 PM, lift...@gmail.com wrote:I have a playbook I'm developing where I'm trying to find any server that has a 0 length /var/log/messages files.
