Is there a way to display only changes and errors

salt-stack

You can set state_verbose: False in /etc/salt/master or /etc/salt/minion. If you want to shorten the output to one line per state, set state_output: terse.

You can also pass these filters on command line:

salt --state-output=terse '*' state.highstate

If you only want to see changes, you can use state-output=changes or state-output=mixed. The latter one will show more information on a failure.

See the following answers fore more detail: basepi, psarossy

We've also added state_output: mixed which will give you the same output as terse, except if there's a failure, in which case it will give you the more verbose output.

To actually answer the question, yes, there is an output filter for changes only:

salt '*' state.highstate --state-output=changes

This will display one liners for things that are in the right state and the proper output for the changes. ie:

There are 2 options, first is to change the state_output in master's configuration file, like mentioned in the accepted answer, and it also possible to override the state output in command line, like:

salt --state-output=mixed \* test.version

As of the following PR that was merged into Salt 2015.8.0 (https://github.com/saltstack/salt/pull/26962) it is now possible to toggle the state_verbose flag from command line when running highstate. This overrides the config you can set in /etc/salt/master that was mentioned in previous answers.

The following command should now display only the changes and errors from a highstate run salt '*' state.highstate --state-verbose=False

Is there a way to display only changes and errors
