How to check the size of a file list - ansible

Question

With Ansible, I need to check if files in directory are bigger than 50M.
I do a set_fact with result of ls and then I loop to stat all files. This works, but I am not able to parse the result to create a fail condition when files are bigger than 50M.
I do this :
- shell: ls -1 "{{ logs_directory }}"*.log
register: list_logs
- set_fact:
list_logs: "{{ list_logs.stdout_lines }}"
- debug:
msg: "{{ list_logs}}"
- name: Get size
stat:
path: "{{ item }}"
with_items: "{{ list_logs }}"
register: size_log
- name: debug
fail:
msg: "Problem with log size > 50M"
when: 'size_log.stat.size / 1024 / 1024 | int > 50'
It works if I have only 1 file, but with multiple servers and multiple files, it doesn't work... How to parse the size_log_result?
Here an example of output size_log :
ok: [192.168.1.2] => {
"msg": {
"changed": false,
"msg": "All items completed",
"results": [
{
"ansible_loop_var": "item",
"changed": false,
"failed": false,
"invocation": {
"module_args": {
"path": "/var/logs/admin.log"
}
},
"item": "/var/logs/admin.log",
"stat": {
"size": 21711,
}
},
{
"ansible_loop_var": "item",
"changed": false,
"failed": false,
"invocation": {
"module_args": {
"path": "/var/logs/database.log"
}
},
"item": "/var/logs/database.log",
"stat": {
"size": 11162,
}
}
]
}
}
ok: [192.168.1.5] => {
"msg": {
"changed": false,
"msg": "All items completed",
"results": [
{
"ansible_loop_var": "item",
"changed": false,
"failed": false,
"invocation": {
"module_args": {
"path": "/var/logs/database.log"
}
},
"item": "/var/logs/database.log",
"stat": {
"size": 128453958,
}
}
]
}
}

It looks to me like you are reinventing the wheel here, when the find module seems to answer you use case perfectly already.
Given:
- hosts: localhost
gather_facts: no
tasks:
####
## You do not need this task, it is just to create a file
## big enough for demonstration purpose
####
- community.general.filesize:
path: /var/log/heavy.log
size: 51m
- find:
paths: /var/log
patterns: '*.log'
size: 51m
register: _logs
- fail:
msg: >-
Due to file(s): {{
_logs.files | map(attribute='path') | join(', ')
}}
when: _logs.files | length > 0
This will yield:
TASK [community.general.filesize] *********************************
ok: [localhost]
TASK [find] *******************************************************
ok: [localhost]
TASK [fail] *******************************************************
fatal: [localhost]: FAILED! => changed=false
msg: 'Due to file(s): /var/log/heavy.log'
