Site Monitor

SiteMonitor is a lightweight Python application that provides real-time monitoring of multiple websites via a small, transparent Tkinter GUI overlay.

It’s designed for minimal system impact while offering adaptive checks, performance tracking, and instant visual feedback.

Features⚓︎

  • Real-time Monitoring: Checks HTTP/HTTPS endpoints continuously.
  • Adaptive Backoff: Sites with repeated failures are checked less frequently.
  • Performance-Based Status: Response times are color-coded:
  • Fast: Green
  • Moderate: Yellow
  • Slow: Blue
  • Failed: Red
  • Minimal GUI: Transparent, draggable overlay with minimal controls.
  • Threaded Checking: Non-blocking checks for multiple sites.
  • Smart Retry Logic: Exponential backoff for failed sites.
  • Low Dependencies: Uses only Python standard library1.

Installation⚓︎

  1. Clone the repository:

    curl -L -o site_monitor.pyw https://raw.githubusercontent.com/abhilashreddysh/AutomationScripts/main/Python/site_monitor.pyw

    wget -O site_monitor.pyw https://raw.githubusercontent.com/abhilashreddysh/AutomationScripts/main/Python/site_monitor.pyw

  2. Run the monitor:

    python site_monitor.pyw

    (or)

    Simply double-click site_monitor.pyw in File Explorer.

    Requires Python 3.9 or later to be installed.

Configuration⚓︎

Most parameters are defined at the top of monitor.py:

CHECK_INTERVAL = 30          # Seconds between checks
REQUEST_TIMEOUT = 2.5        # HTTP request timeout in seconds
MAX_THREADS = 5              # Max simultaneous checks
UPDATE_INTERVAL = 200        # GUI refresh interval in ms
BACKOFF_FACTOR = 1.5         # Adaptive retry multiplier
MAX_BACKOFF = 300            # Max retry delay in seconds
CHANGE_DETECTION_ONLY = True # Only redraw UI on status change

You can also define the websites to monitor:

ENVIRONMENTS = {
    "Google": "https://www.google.com",
    "Example": "https://example.com",
    "GitHub": "https://github.com",
    "StackOverflow": "https://stackoverflow.com",
}

Usage⚓︎

  • The GUI will appear as a small overlay on your desktop.
  • Drag: Right-click2.
  • Close: Left-click2.
  • The color-coded labels indicate the status of each site in real-time.

Architecture⚓︎

  • ConnectionManager: Handles HTTP requests, redirects, and SSL.
  • check_site / check_site_threaded: Perform individual site checks in threads.
  • check_sites_batch: Batch checks with adaptive intervals and thread limiting.
  • process_updates: Efficient GUI update with batching.
  • monitor_loop: Background daemon thread running continuous monitoring.
  • Tkinter GUI: Minimal, draggable, and transparent overlay with dynamic label updates.
