expected output.

Hostname : test

httpd --> Running
ntpd --> Running

Below are the playbook.

---
- hosts: test
become: true
gather_facts: false
tasks:
- name: Service facts
service_facts:

\- set\_fact:
   elk\_app1: "\{\{ ansible\_facts\.services\[item \+ '\.service'\]\.name\}\} Running"
  when: ansible\_facts\.services\[item \+ '\.service'\]\.state == 'running'
  with\_items:
    \- httpd
    \- ntpd
  register: foo\_result

\- debug: msg="\{\{ foo\_result \}\}"

Hello Kumar,

if you use set_fact with a loop, you need to reference the variable on the right hand side:

set_fact:
  elk_app1: "{{ elk_app1 | default('') + ansible_facts.services[item + '.service'].name + ' Running\n' }}"

The default filter is necessary as the variable is undefined on the first iteration of the loop.

Hello Kumar,

use the YAML callback plugin, e.g in ansible.cfg:

# Use the YAML callback plugin.
stdout_callback = yaml

This changes the output to look like as follows:

ok: [buster-test-box] =>
  elk_app1: |-
    sympa.service Running
    wwsympa.service Running
