Grains provide information about the hardware of a client. This includes the operating system, IP addresses, network interfaces, and memory.
When you run a Salt command any modules and functions are run locally from the system being called.
Salt modules are stored on clients and the SUSE Manager Server within the
List all available grains with the
salt '*' grains.ls
You can also use
grains.ls to list collected grain system data:
salt '*' grains.items

States are configuration templates. They allow you to describe what each of your systems should look like, including the applications and services that are installed and running.
States are written, and then applied to the target systems. This automates the process of bringing a large number of systems into a known state, and then maintaining them.
For more information on states, see https://docs.saltstack.com/en/latest/topics/tutorials/starting_states.html.

Pillars are created on the SUSE Manager Server. They contain information about a client or group of clients.
Pillars allow you to send confidential information to a targeted client or group of clients. Pillars are useful for sensitive data, configuration of clients, variables, and any arbitrary data.
For more information on pillars, see https://docs.saltstack.com/en/latest/topics/tutorials/pillar.html.
Beacons allow you to use the Salt event system to monitor non-Salt processes. Clients can use beacons to connect to various system processes for constant monitoring. When a monitored activity occurs, an event is sent on the Salt event bus that can then trigger a reactor.
To use beacons on SUSE Linux Enterprise Server Salt clients, install the
For Red Hat Enterprise Linux systems, install the

The Salt broker allows clients to pass commands to each other.
The Salt broker acts like a switch, therefore peer communication will only work for clients on the same network, or connected to the same proxy.
For more information on Salt and peer communication, see https://docs.saltstack.com/en/latest/ref/peer.html.
SUSE Manager implements Salt with a single environment. Multiple Salt environments are not supported.
