Ansible to consolidate service status on multiple servers - ansible

Question

Below playbook works where inventory groups has multiple servers and to check the status of each service and display its status on console.
Problem is, I wanted to consolidate the status of each service on every server and send in an email, but it seems array (uistatus_app, uistatus_status, uistatus_print) gets re-initiated for each server run.
Is there any way where I can store the status in the global variable of each run and display?
for example:
server1: nginx is active
server1: PHP is active
server2: nginx is active
server2: PHP is unknown
Thanks.
- name: checking services
shell: 'systemctl is-active {{item}}'
with_items:
- nginx
- php74-php-fpm
failed_when: false
register: uistatus
when: 'inventory_hostname in groups[''stg-ui]'
- name: get ui status in arrray
set_fact:
uistatus_app: '{{uistatus_app}}+[ ''{{item.item}}'']'
uistatus_status: '{{uistatus_app}}+[ ''{{item.stdout}}'']'
with_items: '{{ uistatus.results }}'
when: 'inventory_hostname in groups[''stg-ui]'
- name: consolidate
set_fact:
uistatus_print: '{{uistatus_print}}+{{inventory_hostname}}: {{item[0]}} is item[1]}}]'
loop: '{{ query(''together'',uistatus_app, uistatus.status }}'
when: 'inventory_hostname in groups[''stg-ui]'

Set the variable with the list of the statuses in each host, e.g.
- hosts: all
tasks:
- name: checking services
command: "echo {{ item }} is active"
loop:
- nginx
- php74-php-fpm
failed_when: False
register: uistatus
when: inventory_hostname in groups.stg_ui
- set_fact:
my_services: "{{ uistatus.results|default([])|
map(attribute='stdout')|
list }}"
- debug:
var: my_services
gives
ok: [server1] =>
my_services:
- nginx is active
- php74-php-fpm is active
ok: [server2] =>
my_services:
- nginx is active
- php74-php-fpm is active
Then run_once, extract the lists and create the dictionary all_services, e.g.
- set_fact:
all_services: "{{ dict(ansible_play_hosts|zip(stats)) }}"
vars:
stats: "{{ ansible_play_hosts|
map('extract', hostvars, 'my_services')|
list }}"
run_once: true
- debug:
var: all_services
run_once: true
gives
ok: [server1] =>
all_services:
server1:
- nginx is active
- php74-php-fpm is active
server2:
- nginx is active
- php74-php-fpm is active
The dictionary is available to all hosts in the playbook.
