License Management

Overview

Project Overview

Section titled “Project Overview”

The License Management project is a comprehensive solution designed to monitor, manage, and provide insights into license server environments. It consists of two complementary applications that work together to deliver a complete license management ecosystem.

Architecture Overview

Section titled “Architecture Overview”

The project follows a distributed architecture pattern with clear separation of concerns:

graph TB
    subgraph "License Servers"
        LS1[FlexLM Server]
        LS2[RLM Server]
        LS3[sesinetd Server]
    end


    subgraph "Monitoring Layer"
        LM[License Monitor]
        LM --> LS1
        LM --> LS2
        LM --> LS3
    end


    subgraph "Web Interface"
        LSD[License Server Detail]
        LSD --> LM
    end


    subgraph "External Systems"
        OKTA[Okta Authentication]
        OTEL[OpenTelemetry]
        GH[GitHub Releases]
    end


    LSD --> OKTA
    LM --> OTEL
    LM --> GH

License Monitor

Section titled “License Monitor”

License Monitor is the core monitoring component built in Rust. It serves as the data collection and API layer for the entire system.

Key Responsibilities

Section titled “Key Responsibilities”
  • Data Collection: Monitors license server logs and executes license management commands
  • API Server: Provides REST endpoints, WebSocket, and Server-Sent Events for real-time data access
  • Real-time Processing: Processes license data and log entries in real-time
  • Self-Management: Handles its own updates via GitHub Releases integration
  • Observability: Exports metrics and logs to OpenTelemetry

Operating Modes

Section titled “Operating Modes”
  1. Command Mode: Executes license manager commands periodically
  2. Tail Mode: Monitors log files in real-time
  3. API Mode: Runs only the web API server
  4. Both Mode: Combines command and tail modes with API server

License Server Detail

Section titled “License Server Detail”

License Server Detail is the web-based management interface built with Next.js. It provides a comprehensive dashboard for monitoring and managing license servers.

Key Responsibilities

Section titled “Key Responsibilities”
  • User Interface: Provides an intuitive web-based interface for license management
  • Authentication: Handles secure user authentication via Okta
  • Real-time Updates: Displays live data from License Monitor via WebSocket/SSE
  • Data Visualization: Presents license information in an easy-to-understand format
  • User Management: Manages user sessions and permissions

Core Features

Section titled “Core Features”
  • Secure Authentication: NextAuth + Okta integration
  • Real-time Streaming: WebSocket pooling and Server-Sent Events
  • Advanced HTTP Client: Retry logic, circuit breaker, and error handling
  • Production Ready: Structured logging and security features

Data Flow

Section titled “Data Flow”

The system follows a clear data flow pattern:

  1. License Servers generate logs and respond to license management commands
  2. License Monitor collects this data through various monitoring modes
  3. License Monitor processes and stores the data, making it available via API
  4. License Server Detail consumes this data through the API and presents it to users
  5. Users interact with the system through the web interface

Use Cases

Section titled “Use Cases”

The License Management project is designed to address several key use cases:

Enterprise License Management

Section titled “Enterprise License Management”
  • Monitor license usage across multiple servers
  • Track license consumption patterns
  • Identify potential license conflicts or shortages
  • Generate reports for license compliance

Real-time Monitoring

Section titled “Real-time Monitoring”
  • Live monitoring of license server health
  • Real-time alerts for license issues
  • Continuous monitoring of license usage patterns
  • Immediate notification of critical events

Centralized Management

Section titled “Centralized Management”
  • Single point of control for multiple license servers
  • Unified interface for different license server types
  • Centralized logging and monitoring
  • Consistent management across distributed environments

Compliance and Reporting

Section titled “Compliance and Reporting”
  • Detailed license usage reports
  • Historical data analysis
  • Compliance tracking and auditing
  • Performance metrics and trends
