Salt is very well structured. A very important functionality is represented by the execution modules. They are the main entry point into the Salt world. The execution modules are Python modules, and are very easy to read (and eventually write) by anyone with basic Python programming knowledge. Everything is linear, which makes them flexible and easy to understand; in general, they consist only of simple functions.
For complete list of modules – refer to Salt Module Index. It’s respective python repository can be found at Github.
Refer to below image for “salt” cli syntax.
In this post, we will look at the most frequently used module
Grains Module
Function: “items”
Purpose: To collect all grains from the managed system.

Note: When devices is managed by NAPALM i.e. in this case “Router1” – additional grains are collected. Details of these grains can found at Saltstack documentation.
We can also observe that not many grains are found on WLC i.e. “wlc1”. Because of following reasons
- It is managed by “netmiko”
- By default – there is not any existing module for grains collected by “netmiko”
