FWIW. Quoting from 'Performance Data Collection Settings for Runner'  
[https://ansible-runner.readthedocs.io/en/stable/intro/#performance-data-collection-settings-for-runner](https://ansible-runner.readthedocs.io/en/stable/intro/#performance-data-collection-settings-for-runner)

&nbsp;&nbsp;"Runner is capable of collecting performance data (namely  
&nbsp;&nbsp;&nbsp;cpu usage, memory usage, and pid count) during the execution of a  
&nbsp;&nbsp;&nbsp;playbook run. Resource profiling is made possible by the use of  
&nbsp;&nbsp;&nbsp;control groups ..."

Hi Dip!

Assuming that you are referring to this code, note that that Ansible will run python on the target node - Python the interpreter itself will consume memory. And then if you run the shell module under Ansible, it will spawn a shell which itself will consume memory as well.

Hi, All!  
My code:

- name: ===== Блок отримання інформації про виділену RAM ==========================================  
block:
- name: ===== Вівід інформації про виділену, використану та залишок пам’яті ===================  
ansible.builtin.debug:  
msg: “Виділена пам’ять: {{ ansible\_memory\_mb.real.total }} | Використана: {{ ansible\_memory\_mb.real.used }} | Залишилось: {{ ansible\_memory\_mb.real.total - ansible\_memory\_mb.real.used }} ({{ ((1-ansible\_memory\_mb.real.used/ansible\_memory\_mb.real.total)\*100)|int }}%)”

**stdout:**  
ok: **[vl-nr-app1]** =\> {  
“msg”: “Виділена пам’ять: **2619** | Використана: **2004** | Залишилось: **615** (23%)”
