Python Netmon 1.2

v1.2 - SNMP, SQLLite, Plugins
Release Date: 9/2/2024

Core Enhancements

SNMP Integration:

• Implemented SNMP monitoring using the NetOpsSNMP class.
• Added SNMP status checks to determine device reachability, with fallback to ping if SNMP fails.
• Configurable SNMP community strings via config.ini.

SQLite Integration:

• Integrated SQLite database for storing device information, logs, and status updates.
• Introduced SystemLog class to manage program logs, including error handling and informational messages.
• Environment setup now ensures database and required folders are created if they do not exist.

Plugins Architecture

Plugin System:

• Introduced a plugins folder for modular functionality.
• Dynamic Tools menu loads and executes plugins at runtime.

Syslog Plugin:

• Developed a Syslog server plugin that listens for syslog messages and stores them in SQLite.
• Integrated Syslog Viewer in the Tools menu to display and filter syslog messages.

Speed Test Plugin:

• Added a speed test plugin utilizing speedtest-cli.
• GUI for running speed tests and displaying download, upload speeds, and ping.
• Thread-safe GUI updates within the plugin.
• Performance and Stability Improvements

Thread-Safe Queue Management:

• Implemented a thread-safe queue (update_queue) for managing GUI updates from background threads.
• Ensured all GUI interactions from background threads are routed through this queue.

Device Status Tracking:

• Introduced counters for tracking consecutive successes and failures for device checks to prevent intermittent "flashing" statuses.
• Threshold-based mechanism for determining device reachability based on multiple checks.

Error Handling and Logging:

• Improved error handling across modules, with comprehensive logging for easier troubleshooting.
• Enhanced System Log viewer with log level filters and search functionality.
• User Interface and Usability

Reduced Application Size:

• Optimized the codebase, reducing the overall size by approximately 50%.
• Simplified GUI code while adding new features, ensuring a cleaner and more maintainable codebase.

Improved Device Management:

• Streamlined device management dialogs (add, edit, delete) for easier interaction.
• Correctly tracks and highlights acknowledged devices in the Treeview.

Enhanced Visual Feedback:

• Improved visual indicators in the Treeview for device statuses, with color-coding for reachable and unreachable devices.
• Added a countdown timer and progress bar for refresh intervals, giving users clear feedback on the next check.

Environment Setup

Automated Setup:

• Automated environment setup ensures all necessary Python packages are installed.
• Added firewall configuration steps for both Windows and Linux to allow Syslog traffic on UDP port 514.
