Overview

The miner worker system is built on a hierarchical class structure designed to manage and control mining devices in a distributed infrastructure. This documentation covers the abstract class hierarchy and key implementations for the miner worker system.

Architecture

The following is a fragment of MiningOS object model that contains the abstract class representing Miner (highlighted in blue). The rounded nodes reprsent abstract classes and the square nodes represent a concrete classes:

Check out concrete implementations of Miner here:

• miningos-wrk-miner-avalon
• miningos-wrk-miner-whatsminer
• miningos-wrk-miner-antminer

Key Methods:

• init(): Initializes storage and network facilities
• getRpcKey(): Returns the RPC server public key
• getRpcClientKey(): Returns the RPC client public key
• _startRpcServer(): Starts the RPC server
• _start(cb): Starts the worker with RPC endpoints

Configuration:

• Sets up storage directory based on environment
• Configures logging with Pino
• Initializes network facilities for RPC communication

Methods to be overridden by children classes:

• getThingType(): Returns the type of thing (e.g., 'miner')
• getThingTags(): Returns default tags for the thing type
• selectThingInfo(): Selects additional info to include in responses
• collectThingSnap(thg): (Must be overridden: original implementation throws error) Collects a snapshot of the thing's current state
• connectThing(thg): Establishes connection to the thing
• disconnectThing(thg): Disconnects from the thing

Lifecycle Hooks:

• registerThingHook0(thg): Called when registering a new thing
• updateThingHook0(thg, thgPrev): Called when updating a thing
• forgetThingHook0(thg): Called when removing a thing
• setupThingHook0(thg): Called during thing setup

Core Features:

Thing Management:

• Registration: Add new devices to the system
• Updates: Modify device configuration and info
• Deletion: Remove devices from management
• Querying: Search and filter devices

Data Collection:

• Periodic snapshot collection
• Historical data logging (5-minute intervals)
• Alert processing based on snapshots

RPC Endpoints:

• getRack: Get rack information
• queryThing: Query individual thing methods
• listThings: List all managed things
• registerThing: Register new thing
• updateThing: Update existing thing
• forgetThings: Remove things
• applyThings: Apply methods to multiple things
• tailLog: Retrieve historical logs

Miner Worker Implementation

WrkMinerRack

• Source: rack.miner.wrk.js
• Extends: WrkProcVar
• Purpose: Concrete implementation for managing mining devices

Miner-Specific Features:

IP Address Management:

• Static IP assignment support
• Dynamic IP allocation
• IP release on device removal or maintenance

Validation:

• Prevents duplicate serial numbers
• Prevents duplicate MAC addresses
• Prevents duplicate container positions
• Prevents duplicate IP addresses

Miner Properties:

{
  opts: {
    address: string,    // IP address
    port: number,       // Connection port
    forceSetIp: boolean // Force IP assignment
  },
  info: {
    serialNum: string,  // Device serial number
    macAddress: string, // Network MAC address
    pos: string,        // Position in container
    container: string,  // Container ID
    location: string    // Physical location
  }
}
