Resolve Debug Monitor
Real-Time Debug Output Monitor for Windows Applications
Overview
Resolve Debug Monitor is a desktop application for capturing and analyzing debug output from Windows applications in real-time. Whether you're monitoring log files or capturing live debug messages, it provides powerful filtering, alerting, and visualization tools to help you identify issues quickly. The application runs quietly in your system tray and can alert you instantly when critical events occur.
Input Modes
Resolve Debug Monitor supports two primary methods for capturing debug output:
File Tail Mode
Continuously monitors a log file on disk, displaying new lines as they are written. Ideal for applications that write debug output to text files.
- Automatically detects file truncation or replacement and reloads from the beginning
- Creates the target directory if it doesn't exist
- Default target: ResolveDebug.txt (configurable via Registry)
DebugView Mode
Captures OutputDebugString messages from any Windows application—the same debug stream shown by Microsoft's DebugView utility.
- Displays process ID, process name, elapsed time, and time delta between messages
- Configurable column ordering and visibility—show only the information you need
- Supports both global capture (for services/session 0) and session-local capture
- Optional timestamp column showing wall-clock time for each message
Severity Indicators & Alerts
Three color-coded severity levels help you quickly identify important events:
- Red (Critical): Highest priority—errors, exceptions, and critical failures
- Orange (Warning): Medium priority—warnings, deprecation notices, potential issues
- Cyan (Info): Lower priority—informational messages, milestones, events of interest
Pattern Matching: Each indicator supports substring, prefix, suffix, and full regular expression matching.
Alert Actions:
- Pop-to-front: Automatically bring the window to the foreground when a match occurs (with cooldown)
- Windows notifications: Toast notifications with priority-based queuing (Red > Orange > Cyan)
SOLO Filtering
SOLO mode isolates log output by severity level, hiding other lines to focus on specific event types.
- Press F1, F2, or F3 to toggle SOLO for Red, Orange, or Cyan events
- Multiple SOLO filters can be active simultaneously to show combined results
- Press F4 to clear all SOLO filters and return to full output
- Double-click a colored line to activate SOLO for that severity (deactivates others)
- Double-click again while in SOLO mode to exit and return to full output
Keyboard Shortcuts
- F1 / F2 / F3: Toggle SOLO filter for Red / Orange / Cyan events
- F4: Clear all SOLO filters
- F5: Toggle between last two window sizes
- F6: Clear terminal output
- F7: Open Highlight Settings dialog
- F8: Start or stop monitoring
- Space: Pause or resume output (monitoring continues in background)
- Ctrl+A: Select all log lines
- Ctrl+C: Copy selected lines to clipboard
- Ctrl+MouseWheel: Zoom font size in or out
- Ctrl+Up / Ctrl+Down: Adjust line spacing density
- Ctrl+0: Reset line spacing to default
- Alt+Up / Alt+Down: Navigate to previous/next severity line
- Home / End: Jump to first/last line
- Shift+?: Show keyboard shortcuts help
- Enter: Activate selected line (same as double-click)
Context Menu Actions
Right-click the output area to access:
- Copy / Copy All: Copy selected lines or entire buffer to clipboard
- Open in Notepad: Open selected lines in Notepad for analysis
- Add to Highlights: Quickly add words under the cursor to highlight patterns
- Select Font: Open the font picker dialog
- Line Spacing: Choose from Normal through Ultra Compact presets
- Configure DebugView Columns: Customize columns in DebugView mode
Remote Monitoring (HTTP Server)
A built-in HTTP server lets you view log output from any device on your local network.
- Access from any web browser via the host machine's IP address and port
- Terminal-style HTML rendering preserves color coding
- Viewport mirror mode (shows GUI view) or full buffer mode
- Configurable port; set to 0 to disable
Display & Appearance
- Font selection: Any installed font with control over weight, style, and stretch
- Proportional scaling: Font size adjusts automatically as you resize the window
- Line spacing presets: Normal, Compact, Super Compact, Hyper Compact, Ultra Compact
- Always-on-top: Keep the window visible above all other applications
- Custom highlights: Define additional patterns beyond the three severity indicators
- Pipe truncation: Hide leading columns in pipe-delimited output
System Tray & Configuration
- Lives in the system tray—stays out of your way while monitoring
- Minimizing hides the window completely; click tray icon to restore
- Right-click tray icon for show/hide, start/stop, and exit
- Single-instance enforcement—only one copy runs at a time
- All settings saved to Windows Registry and restored on launch
