Ansible parse debug output - ansible

Question

I have this ansible output got from 3 different hosts, using ansible debug module:
TASK [debug] ***************************************************************************************************************************************************************************************
ok: [10.240.22.44] => {
"msg": {
"changed": true,
"msg": "All items completed",
"results": [
{
"_ansible_ignore_errors": true,
"_ansible_item_result": true,
"_ansible_no_log": false,
"_ansible_parsed": true,
"changed": true,
"cmd": "/opt/confluent/bin/nodefirmware smm1",
"delta": "0:00:00.128325",
"end": "2020-02-05 11:22:19.435049",
"failed": false,
"invocation": {
"module_args": {
"_raw_params": "/opt/confluent/bin/nodefirmware smm1",
"_uses_shell": true,
"chdir": null,
"creates": null,
"executable": null,
"removes": null,
"stdin": null,
"warn": true
}
},
"item": "10.240.18.20",
"rc": 0,
"start": "2020-02-05 11:22:19.306724",
"stderr": "",
"stderr_lines": [],
"stdout": "smm1: SMM: 1.10 (TESM14F)\nsmm1: PSOC: 0.7",
"stdout_lines": [
"smm1: SMM: 1.10 (TESM14F)",
"smm1: PSOC: 0.7"
]
},
{
"_ansible_ignore_errors": true,
"_ansible_item_result": true,
"_ansible_no_log": false,
"_ansible_parsed": true,
"changed": true,
"cmd": "/opt/confluent/bin/nodefirmware smm1",
"delta": "0:00:00.096292",
"end": "2020-02-05 11:22:22.847949",
"failed": false,
"invocation": {
"module_args": {
"_raw_params": "/opt/confluent/bin/nodefirmware smm1",
"_uses_shell": true,
"chdir": null,
"creates": null,
"executable": null,
"removes": null,
"stdin": null,
"warn": true
}
},
"item": "10.240.19.21",
"rc": 0,
"start": "2020-02-05 11:22:22.751657",
"stderr": "",
"stderr_lines": [],
"stdout": "smm1: SMM: 1.10 (TESM14F)\nsmm1: PSOC: 0.7",
"stdout_lines": [
"smm1: SMM: 1.10 (TESM14F)",
"smm1: PSOC: 0.7"
]
}
]
}
}
I'm trying to parse this output and display in the end, for each hosts, strictly the:
"stdout_lines": [
"smm1: SMM: 1.10 (TESM14F)",
"smm1: PSOC: 0.7"
The playbook that shows the above output is this:
- debug:
msg: "{{ smm_output }}"
when: "('primary' in default_hostname or 'Primary' in default_hostname)"
tags: ['ic', 'smm']
I tried with "{{ smm_output.stdout_lines }}" but says there's not such dict object
Any clues?

You are registering the output of a looping task. Quoting the documentation:
When you register a variable in a task with a loop, the registered variable contains a value for each item in the loop. The data structure placed in the variable during the loop will contain a results attribute, that is a list of all responses from the module. For a more in-depth example of how this works, see the Loops section on using register with a loop.
To debug each stdout_lines of your respective results in smm_output you can use the following task:
- name: debug result
debug:
var: item.stdout_lines
loop: "{{ smm_output.results }}"
