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.
