feat: Add base HTML template and implement dashboard, logs, and service views
- Created a base HTML template for consistent layout across pages. - Developed a dashboard page to display backup service metrics and statuses. - Implemented a log viewer for detailed log file inspection. - Added error handling page for better user experience during failures. - Introduced service detail page to show specific service metrics and actions. - Enhanced log filtering and viewing capabilities. - Integrated auto-refresh functionality for real-time updates on metrics. - Created integration and unit test scripts for backup metrics functionality.

# Author: Peter Wood <peter@peterwood.dev>
|
||||
# Description: Lightweight backup metrics tracking for personal backup systems.
|
||||
# Provides essential status tracking without enterprise complexity.
|
||||
#
|
||||
# Features:
|
||||
# - Simple JSON status files (one per service)
|
||||
# - Basic timing and file counting
|
||||
# - Minimal performance overhead
|
||||
# - Easy to debug and maintain
|
||||
# - Web interface ready
|
||||
#
|
||||
# Usage:
|
||||
# source /home/acedanger/shell/lib/unified-backup-metrics-simple.sh
|
||||
#
|
||||
# metrics_backup_start "service-name" "description" "/backup/path"
|
||||
# metrics_update_status "running" "Current operation"
|
||||
# metrics_file_backup_complete "/path/to/file" "1024" "success"
|
||||
# metrics_backup_complete "success" "Backup completed successfully"
