Only show output for changed things?

[Josh Smift]

Is there a way to tell Ansible to only show output for things that have
changed? We've got playbooks that include roles and run dozens of tasks,
and often want to check to see what's going to happen before we actually
run them (because we share some common code between a couple of sites,
each of which has its own Ansible servers, so things sometimes drift over
time), and that'd be easier to do if the output wasn't full of "ok:"
reports. (It also seems nicely consistent with the Unix principle that
silence == success, which isn't always what you want, but which is nice to
be able to get when it *is* what you want.)

Ansible will print everything, because it's important to know when things come back.

If you want a good way to skim status for changed, not changed, and filter, etc, sometimes a command line can break down and not be the best fit.

Ansible Tower, particularly in version 2.0, provides a very nice UI for exploring that kind of info, for those interested - http://ansible.com/tower.

Otherwise, no, there's not a way to shut it off.

I am hesitant to provide it because I think knowing when hosts return is important.

In our usage, we frequently don't care at all when things come back: We
have a playbook that we know is going to take several minutes to run
(dozens of tasks on dozens of hosts), so we fire it off, go do something
else, and check back a while later to see what it did. If the recap at the
bottom looks like we expect, that's great; if it doesn't, it'd be really
useful to just see the failures, so we could quickly see what went wrong.

(This is for things like system configuration management, the "make sure
everything on this system is configured like it's supposed to be" sort of
playbook.)

You might want to consider using Tower.  It makes it easy to delve in to specific results and the 2.0 version has a very very nice view for this.

You can quickly ignore things you don't care about.

CLI output is great -- we don't hamstring it, but somethings are hard to dig through.

I do not think making a way to turn off non-changed server info coming back is a good idea - if something didn't come back, you would not easily know.

You could also consider using callback plugins to form up your own alternative log.
