Running state.apply or state.highstate on minions can result in hundreds of lines in output. Sometimes only one minion can be enough.

...
Summary for my_minion
--------------
Succeeded: 112 (changed=78)
Failed:      6
Warnings:    1
--------------
Total states run:     118
Total run time:     4.958 s

Is there a way to show only failed and warnings in the output?

I fail to call a single state of an sls file.

Whole sls file works

This works:

salt-ssh w123 state.sls monitoring

This works:

salt-ssh w123 state.show_sls monitoring

One item of above output:

monitoring_packages:
    ----------
    __env__:
        base
    __sls__:
        monitoring.packages
    pkg:
        |_
          ----------
          pkgs:
              - python-psutil
        - installed
        |_
          ----------
          order:
              10000

What I tried

Now I want to call only monitoring_packages, not the whole sls file:

Fails:

salt:/srv # salt-ssh w123 state.sls_id monitoring_packages  monitoring
w123:
    Data failed to compile:
----------
    No matching sls found for 'monitoring' in env 'base'

Fails:

salt:/srv # salt-ssh w123 state.single monitoring.monitoring_packages
w123:
    TypeError encountered executing state.single: single() takes at least 2 arguments (1 given)

Question

How to call my single state monitoring_packages?

Version

salt:/srv # salt-ssh --version
salt-ssh 2015.8.3 (Beryllium)

What I'd like to do is generate multiple configuration files for each openvpn user. I have the IP address and additional configuration in pillar.

For example:

openvpn:
  - user1:
    ip: 1.2.3.4
    config:
      - line1
      - line2

In the SLS I'd like to do something like:

{% for vpnuser in salt['pillar.get']('openvpn') %}
/etc/openvpn/ccd/{{ vpnuser }}:
  file.managed:
    - template: jinja
    - source: salt://openvpn/ccdtemplate
{% endfor %}

and in the ccdtemplate I'd like to generate the config depending on the user and the config data for this user stored in pillar.

But therefor I would need to know the content of the variable 'vpnuser' from the state.

Is it possible to pass variables from a state to the jinja template?

I have to execute a state only once. I couldn't find a simple way to do this.

Now, the context

I install two MySQL servers through salt. I want to make one a slave of the other.

In order to setup the slave, I need to get the master status informations at the end of the master installation:

SHOW MASTER STATUS;

Now, I can use a custom state executing the mysql.query function to get it.

mysql_master_status:
  mystate.query:
    - query: SHOW MASTER STATUS

But it will be executed every time the highstate is executed for my server. Thus giving different master information every time.

I tried to use a file existence as a flag:

/tmp/only_once:
  file.missing: []
mysql_master_status:
  mystate.query:
    - query: SHOW MASTER STATUS
    - require:
      - file: /tmp/only_once

It's working but I was not happy since I now have two failing states every time.

My custom solution

I ended with a new parameter for mystate, flag that create a flag file the first time it is executed, and returns with success if the file exists:

mysql_master_status:
  mystate.query:
    - query: SHOW MASTER STATUS
    - flag:  /tmp/only_once

And the question again

Still, I'd like to know if, and how, one would execute a state only once.

Sometimes my saltmaster hangs for a while on salt '*' test.ping waiting for downed minions to reply. Is there a way so see a list of connected minions, regardless of whether they respond to test.ping?
