Why doesn't debug get me the output of these commands

[Pro Va]

Hello All ,

I am trying to run a playbook that gets me the status of Postfix instances running on an email relay server.

my playbook looks like this :

******************************************************************************

  - name: checking status of Inbound Instance

    command: postmulti -i postfix-in-1 -p status

    register: result

    ignore_errors: yes

    changed_when: False

    become: yes

  - name: showing in-1 status

    debug:

     var: result.stdout

  - name: checking status of Outbound Instance

    shell: /usr/sbin/postmulti -i postfix-out-1 -p status

    register: result2

    become: yes

    changed_when: False

  - debug: msg="{{ result2.stdout }}"

*******************************************************************************

i am expecting an output like this , which normally gets written to screen when run on the server :

postfix-in-1/postfix-script: the Postfix mail system is running: PID: 8218

postfix-out-1/postfix-script: the Postfix mail system is running: PID: 7321

but ansible playbook has a null stdout or stdout_lines .

any suggestions appreciated : ) .

Which command did you run, and what output did you get from that (copied as text, not as images/attachments/screenshots)?

Thanks for your response , if i run this command on email relay server running postfix 

" postmulti -i postfix-in-1 -p status " >> it gives me the following output >> " postfix-in-1/postfix-script: the Postfix mail system is running: PID: 8218 "

this tells me the instance is running , now i wanted my playbook to run the same command on the server and capture the output .

I basically wanted to run this playbook on a group of mail servers to check if postfix instance is running .

Ty.

My ansible playbook output is like this :

ok: [192.x.x.x] => {

    "msg": ""

}

ok: [192.x.x.x] => {

    "msg": ""

}

ok: [192.x.x.x] => {

    "msg": ""

}

ok: [192.x.x.x] => {

    "msg": ""

}

so it tells me the command is executed but doesn't capture the output of the command as stdout.

For some reason postmulti's output is sent to stderr instead of stdout.
