Network Device Manager (NDM)

The Network Device Monitoring subsystem provides a dedicated device page for each discovered network device, enabling in-depth monitoring of device information, configurations, and troubleshooting.

Features and Functionalities

Upon selecting a specific device from the Device Provisioning page, users are directed to a comprehensive Device Monitoring Page. This page serves as an information hub, offering insights into the device’s health, operational status, and configuration. Key categories include:

Physical & Logical View of Device Interfaces

  • Physical Device Image: Displays a visual representation of the actual device, helping with physical identification and layout understanding.

  • Interface Status with Color Coding: Each interface is displayed with an operational status color:

    • 🟢 Green – Interface is up and functioning normally

    • 🔴 Red – Interface is down or in error

    • ⚪ Grey – Interface does not exist

    • 🟠 Orange – Interface is experiencing an anomaly

Detailed Interface Information and Control

Administrators can access a detailed table listing each interface's critical information:

  • Interface name and ID

  • Link speed and duplex mode (e.g., 100 Mbps, 1 Gbps, full/half duplex)

  • VLAN membership

  • Real-time traffic statistics (incoming/outgoing bytes and packets)

Each interface row also includes a toggle switch for enabling or disabling the interface, simplifying control and operational management.

Anomaly Detection and Visualization

A built-in anomaly detection system continuously monitors device behavior and visually flags irregularities:

  • 🟠 Orange Interface Color: Indicates an anomaly has been detected.

  • Hover for Details: Hovering over the orange interface provides a tooltip describing the detected issue.

Note: The current prototype focuses on a single anomaly (interface protection mode). However, this system is extendable to cover additional detections like HTTP port status.

Syslog Monitoring and Filtering

A dedicated section of the NDM page displays recent syslog entries, offering valuable insights into device events and issues.

  • Detailed Syslog View: Shows the 10 most recent entries by default, with descriptions and severity levels.

  • Severity Classification: Logs are classified from 0 (Critical) to 7 (Informational).

  • Pagination & Filtering:

    • Navigate through logs in pages of 10

    • Future versions may include filtering by:

      • Severity level

      • Precise time range (down to seconds)

By integrating these features, the NDM Device Page gives network administrators a centralized interface for device monitoring, anomaly detection, and operational oversight.

Future Enhancements

To further enrich the monitoring experience, future versions of NDM are planned to include:

Device Health and Performance Monitoring

  • CPU Usage: Monitor trends in CPU load to identify performance issues.

  • CPU Temperature: Track thermal conditions to prevent overheating.

  • Error Statistics: Log TX/RX error rates to detect potential data integrity problems.

  • Packet Loss: Monitor for network reliability issues caused by lost packets.

History of Connected End Devices

  • Device Info: MAC address, IP, and type of connected devices.

  • Port Utilization: Record of which port each device used and for how long.
