how to group results by value

[Heiner W]

Hi List!

i usually check if all my systems are configured equally before modifying any config on those systems. Or sometimes i find a system with wrong config and need to know if/which other systems are also affected.

Is there a clever way of comparing the results of salt commands given to multiple clients?

e.G.:

If i execute # salt multipleclients*  grains.get virtual on master i would like salt to group results by values (in our case one group for "physical" and one for "VMware").

hey there. there is a nifty runner that can be used for this.

https://docs.saltproject.io/en/latest/ref/runners/all/salt.runners.survey.html

here is an example output

root@salt00:~# salt-run survey.hash \* grains.get pythonversion

      - dbz.novalocal
      - devbox.novalocal
      - ipa.wolfnet.bad4.us
      - media.wolfnet.bad4.us
      - zabbix.novalocal
  result:
      [3, 6, 8, 'final', 0]
