Aggregating debug msg output

[Dimitri Yioulos]

Taking, e.g., the following simple playbook:

---

- hosts: all

  gather_facts: false

  serial: 1

  tasks:

    - name: system date

      command: date

      register: date_out

    - name: print system date

      debug:

        msg: "Hostname is: {{ inventory_hostname }} and System date is: {{ date_out.stdout_lines[0] }}"

Rather than the msg output is interspersed thoughout, I'd like to aggregate all of the debug messages from the various hosts into consecutive lines, like this:

ok: [host1] => (item=Thu Sep 16 12:41:03 EDT 2021) => {

    "msg": "Hostname is: host1 and System date is: Thu Sep 16 12:41:03 EDT 2021"

}

ok: [host2] => (item=Thu Sep 16 12:41:03 EDT 2021) => {

    "msg": "Hostname is: host2 and System date is: Thu Sep 16 12:41:03 EDT 2021"

}

I hope I'm clear on my ask.  Is this possible and, if so, how do I do it?

Thanks!

Hello,

Not sure whether I'll got the point. However, using a template file you could collect the fact sysdate on every host and print the hostname and all sysdate in a task delegated to localhost.

 ... additions to playbook ...

    - set_fact: sysdate={{ date_out.stdout_lines[0] }}

    - name: dump to /tmp/DUMP

      template:

        src: dump.j2

        dest: /tmp/DUMP

      delegate_to: localhost

Template named "dump.j2" as referred in playbook. It's located in same directory as the playbook.

{% for host in ansible_play_hosts  %}

Hostname is: {{ host }} and System date is: {{ sysdate }}

{% endfor %}

There is also a possibility to loop over the hosts in a delegated_to task, but I don't remember the syntax at the moment.

BR,

Roland

Thanks, Roland.  The fact is, I'd like to "aggregate" (for lack of a better term) any debug msg output, regardless of what information the playbook is trying to gather.  The one I posted above is for descriptive purposes.  Rather than have output of the playbook look like this:

PLAY [all] *********************************************************************

TASK [system date] *************************************************************

Thursday 16 September 2021  11:49:07 -0400 (0:00:00.037)       0:00:00.037 ****

changed: [host1]

TASK [print system date] *******************************************************

Thursday 16 September 2021  11:49:08 -0400 (0:00:00.889)       0:00:00.927 ****

ok: [host1] => {

    "msg": "Hostname is: host1 and System date is: Thu Sep 16 11:49:08 EDT 2021"

}

PLAY [all] *********************************************************************

TASK [system date] *************************************************************

---

Thursday 16 September 2021  11:49:08 -0400 (0:00:00.059)       0:00:00.986 ****

changed: [host2]

TASK [print system date] *******************************************************

Thursday 16 September 2021  11:49:09 -0400 (0:00:00.965)       0:00:01.951 ****

ok: [host2] => {

    "msg": "Hostname is: host2 and System date is: Thu Sep 16 11:49:09 EDT 2021"

}

PLAY RECAP *********************************************************************

~

I'd want the to look like this:

PLAY [all] *********************************************************************

TASK [system date] *************************************************************

---

Thursday 16 September 2021  11:49:08 -0400 (0:00:00.059)       0:00:00.986 ****

changed: [host1]

Thursday 16 September 2021  11:49:07 -0400 (0:00:00.037)       0:00:00.037 ****

changed: [host2]

TASK [print system date] *******************************************************

ok: [host1] => (item=Thu Sep 16 12:41:03 EDT 2021) => {

    "msg": "Hostname is: host1 and System date is: Thu Sep 16 12:41:03 EDT 2021"

}

ok: [host2] => (item=Thu Sep 16 12:41:03 EDT 2021) => {

    "msg": "Hostname is: host2 and System date is: Thu Sep 16 12:41:03 EDT 2021"

}

PLAY RECAP *********************************************************************

Is that possible?

Save all your output to the file and assemble it using assemble module. 

[Oskar Almlöv]

If I’m correctly understanding what it is you want I suggest that you look into the “throttle” keyword. It can be used for serial like behavior but on individual tasks or blocks.
