how to use when condition in ansible - ansible

Question

I have the part of the script:
- name: To Display SPLUNK Status
shell: service splunk status | grep PID
register: STATUS
- name: Showing SPLUNK Status
debug: var=STATUS.stdout_lines
- name: Getting Process IDs of the SPLUNK
shell: ps -ef|grep -i splunk
register: pids_of_SPLUNK
- name: Printing the process IDs obtained
debug: var=pids_of_SPLUNK.stdout_lines
#- name: SPLUNK is NOT running
- debug: msg="Splunk is NOT running"
when: not STATUS.stat.exists
#- name: SPLUNK is Running
- debug: msg="Splunk is Restarted and Running"
that line getting me the error: when: not STATUS.stat.exists
when splunk is running it has the status:
Splunk status:
splunkd is running (PID: 7198).
splunk helpers are running (PIDs: 7200).
When splunk is not running:
Splunk status:
splunkd is not running.
how I can use: when condition for it ?
Thank you.

Use service_facts. For example
vars:
my_services:
- 'splunk'
- 'apache2'
- 'ssh'
tasks:
- service_facts:
- debug:
msg: "Service {{ item }} is not available."
loop: "{{ my_services }}"
when: item not in ansible_facts.services.keys()|list
- debug:
msg: "Service {{ item }} is available."
loop: "{{ my_services }}"
when: item in ansible_facts.services.keys()|list
- debug:
msg: "{{ item }} is {{ ansible_facts.services[item].state }}"
loop: "{{ my_services }}"
when: item in ansible_facts.services.keys()|list
give
"msg": "Service splunk is not available."
"msg": "Service apache2 is available."
"msg": "Service ssh is available."
"msg": "apache2 is stopped"
"msg": "ssh is running"
