Customized error message on failed task?

[John Harmon]

I have googled this, and found I am not the first to ask.  I have the following:

- name: Check if NetworkManager is running
  shell: "systemctl status NetworkManager"
  register: nm_status
  changed_when: false
  ignore_errors: yes
  when: ansible_distribution_major_version == '7'

When it errors out, thanks to systemd, there is a whole bunch of garbage.  I would like the following instead
msg: "NetworkManager not enabled"

I haven't been able to get this to work yet with what I have googled....  anyone else been able to do something like this?

I can suppress it with the following, but I haven't been able to customize it

no_log: true

You would need to write you own callback plugin, or check the included
ones to see if one of them suit your need.
