Saltstack Query
-
Salt does not store the data about the clients in a database. If you want something like that, you have to build a database yourself and populate it with data pulled from SaltStack. SaltStack maintains, in state files, a list of how you want machines to be configured. It does not maintain a list of how they are configured. It's a tool that is meant to be combined with other things.
-
So to get this information, you would use SaltStack, as Dustin pointed out, to query each Minion and ask it if a package is installed or not. Then you'd use either your eyes to do it manually, or script something to process the resulting list. If you have twenty or even fifty machines, you might just look at the results. If you have hundreds or thousands, you likely want to process it. If you need to do this task all of the time, you might want to do something more.
-
You could of course pipe the output of SaltStack into a csv and then just grab that CSV to do more filtering. But you need to get the data first.

@DustinB3403 Damn, I was trying too hard. I can use that and filter through grep. Thanks DustinB3403!

I believe if you supply the package name in place of foo that you wouldn't need to do any additional filtering.

@scottalanmiller That make more sense. So my saltmaster may be in control but it needs to pull specific information on configuration directly from the minions. That explains why I couldn't find the database. I appreciate the clarity.

Correct. No problem.
My team at SodiumSuite (currently unavailable as it is being re-written) does exactly this, making a SaltStack management system that contains that configuration data on the back end and uses SS as just part of the tooling for a more general management and monitoring solution - specifically because SaltStack lacks that visibility and monitoring on its own.

@DustinB3403 The problem is that this command pulls information on pkgs installed on the saltmaster. I would need to go to each of 200 machines and run it to get that machines software list unless there is a way to direct that command to a list of minions. Then I could produce a list of all minions and create a for loop to query each one and output results to a text file, or am I overthinking again?

The
'*'should target all of your minions by default. . . -

Salt command run against the Minions. The master might be one of the minions, but also may not be.

@scottalanmiller OK, I see what is happening; I have a very complete list of installed software but only a few of the minions. The last three minion names did not respond (probably turned off). Does the command abort after a certain number of failures?
-
Does the SaltMaster maintain a list of all the minions?
-
@roninmage it shouldn't just abort, instead it tells every minion to report back.
How many minions do you have?
-
@roninmage run this to list all minions
salt-run manage.up -
@DustinB3403 Somewhere from 350 - 500

Does the output you received have your minion list? You said "OK, I see what is happening; I have a very complete list of installed software but only a few of the minions. The last three minion names did not respond (probably turned off)."

Yes, it only tries for so long, but it can be a while.

Yes, it has to, or else it couldn't reach them.

@scottalanmiller OK, my screw-up. I just found out there are two saltmasters. One for Windows systems and the other for Linux boxes. That explains things. Only about 150 Windows systems. That may be all I need to address. I ran the command on the Windows saltmaster and have a nice list to work with. I appreciate all the help guys. This would have taken me many hours without your assistance.

No problem. Glad that we could help.
