I’ve developed a Python-based network monitoring tool to help me keep track of the status and performance of devices on my network. At its core, the tool is built to be efficient, scalable, and user-friendly. It utilizes asyncio for efficient asynchronous network operations, tkinter for the graphical user interface (GUI), and subprocess to execute ping commands. These libraries work together seamlessly to provide real-time monitoring without blocking the main thread, ensuring the application remains responsive even when handling multiple devices.

The asyncio library is the backbone of the tool, allowing me to perform network operations like pinging devices and resolving hostnames asynchronously. This means I can monitor multiple devices simultaneously without waiting for one operation to complete before starting the next. For example, the ping_device method uses asyncio.create_subprocess_exec to run ping commands in a non-blocking way, while the resolve_hostname method leverages asyncio to resolve hostnames to IP addresses efficiently.

The tkinter library powers the GUI, providing a clean and intuitive interface for interacting with the tool. I’ve designed the interface to include sections for adding devices (by IP or hostname), setting refresh intervals, and managing custom notes for each device. The Treeview widget is used to display device status, notes, and ping statistics in a sortable table, with color-coded rows to quickly identify online (green) and offline (red) devices. The GUI also includes buttons for starting, stopping, and exporting monitoring logs, making it easy to control the tool and analyze results.

To execute ping commands, I rely on the subprocess library, which allows me to run system-level commands like ping from within the Python script. The tool dynamically adjusts the ping command based on the operating system (Windows or Unix), ensuring compatibility across platforms. For example, on Windows, the command uses -n for the number of packets and -w for the timeout, while on Unix-based systems, it uses -c and -W respectively. The output of the ping command is then parsed using regular expressions to extract key statistics like packet loss and average response time.

Here’s a quick breakdown of how these components work together:

1. Asynchronous Monitoring: The start_monitoring method uses asyncio.gather to ping all devices concurrently, updating the UI in real-time through a thread-safe queue.

2. Data Persistence: The tool automatically saves the list of devices and their notes to a JSON file using Python’s json module. This ensures that my data is preserved between sessions.

3. Error Handling and Logging: I’ve added robust error handling and logging using Python’s logging module, so I can quickly diagnose and resolve any issues that arise.

Overall, this tool has become an essential part of my network management workflow. It’s modular, scalable, and packed with features that make monitoring network devices a breeze. Whether I’m diagnosing connectivity issues or just keeping an eye on network performance, this tool has everything I need to stay on top of things.

This macropad was a very impulsive buy. I was attracted to the aesthetics far before the actual functionality. Even if I didn't get much use out of it, I thought that it's "gadget-like" form would still suffice as a good party trick.

It is compact and customizable, which allows users to create their own custom keyboard shortcuts for various applications. The controller is built around the Raspberry Pi RP2040 microcontroller and features 3x3 keys that can be programmed to perform any desired function.

To program this little beast, you can use any IDE. If you want see it's live functionality without unplugging the device every time to test, you would want to use CircuitPython. You can theoretically program this device using any language, although Python is friendliest the a new user. If you would like to use another language, I would recommend C++.

This gadget turned out to be much more than a piece of nerdy eye candy. I use it everyday for a shortcuts such as snippet, and "replying to all". I use the knob to turn to different profiles as my workflow changes. I test my scripting skills by creating new profiles as I see necessary. Overall I would recommend this to anyone looking to dive into DIY macropads or they just want a cool desk accessory!

Just be ready for some small "script kiddie" like work.
