From d68e676de3ccb05b48bcd0f200aed3fccf863b28 Mon Sep 17 00:00:00 2001 From: James Paterni Date: Tue, 15 Jul 2025 10:31:09 -0400 Subject: [PATCH] Enhance dashboard with next backup time, reorganized layout, and pagination MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Dashboard Improvements ### 1. Add Time to Next Backup Display - Add new `/next-backup` endpoint with cron schedule parsing - Display time until next backup in human-readable format (e.g., "16 hours") - Show formatted next backup time (e.g., "07:00am") - Add next backup info to System Health card with schedule details - Include format_time_until helper for readable time formatting ### 2. Reorganize Dashboard Layout - Move "Discovered Containers" section above "Recent Backups" - Improve workflow by showing monitored containers before backup history - Better logical flow for users checking system status ### 3. Add Pagination to Recent Backups - Implement client-side pagination with 10 backups per page - Add pagination controls with Previous/Next buttons and page info - Show "Page X of Y" information when multiple pages exist - Hide pagination when 10 or fewer backups exist - Maintain all existing backup display functionality ### 4. Load Historical Backups on Startup - BackupMonitor now scans existing .meta files on initialization - Loads historical backup data from metadata files into backup history - Estimates duration for historical backups based on file size - Maintains chronological order and 1000-record memory limit - Dashboard now shows complete backup history immediately ### Technical Changes - Add loadNextBackupTime() function with auto-refresh - Implement displayBackupsPage() with pagination logic - Add CSS classes for pagination styling - Update refreshAll() to include next backup time - Remove duplicate loadRecentBackups functions - Add proper error handling for all new endpoints Dashboard now provides comprehensive backup monitoring with improved user experience and complete historical data visibility. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- app/app.rb | 9 +- app/lib/baktainer/backup_monitor.rb | 70 +++++- app/lib/baktainer/dashboard.html | 240 +++++++++++++++----- app/lib/baktainer/file_system_operations.rb | 23 +- app/lib/baktainer/health_check_server.rb | 55 ++++- 5 files changed, 323 insertions(+), 74 deletions(-) diff --git a/app/app.rb b/app/app.rb index 30c4489..069bd4e 100644 --- a/app/app.rb +++ b/app/app.rb @@ -30,4 +30,11 @@ baktainer = Baktainer::Runner.new( } ) -baktainer.run \ No newline at end of file +if options[:now] + LOGGER.info('Running backup immediately (--now flag)') + baktainer.perform_backup + LOGGER.info('Backup completed, exiting') + exit 0 +else + baktainer.run +end \ No newline at end of file diff --git a/app/lib/baktainer/backup_monitor.rb b/app/lib/baktainer/backup_monitor.rb index f625fa7..12c02c8 100644 --- a/app/lib/baktainer/backup_monitor.rb +++ b/app/lib/baktainer/backup_monitor.rb @@ -15,6 +15,9 @@ class Baktainer::BackupMonitor @start_times = Concurrent::Hash.new @backup_history = Concurrent::Array.new @mutex = Mutex.new + + # Load historical backups on startup + load_historical_backups end def start_backup(container_name, engine) @@ -162,12 +165,75 @@ class Baktainer::BackupMonitor private + def load_historical_backups + backup_dir = ENV['BT_BACKUP_DIR'] || '/backups' + + unless Dir.exist?(backup_dir) + @logger.debug("Backup directory #{backup_dir} does not exist, skipping historical backup loading") + return + end + + @logger.info("Loading historical backup data from #{backup_dir}") + + begin + # Find all .meta files recursively + meta_files = Dir.glob(File.join(backup_dir, '**', '*.meta')) + loaded_count = 0 + + meta_files.each do |meta_file| + begin + # Read and parse metadata + metadata = JSON.parse(File.read(meta_file)) + + # Convert to backup history format + backup_record = { + container_name: metadata['container_name'], + timestamp: metadata['timestamp'], + duration: estimate_backup_duration(metadata['file_size']), + file_size: metadata['file_size'], + file_path: File.join(File.dirname(meta_file), metadata['backup_file']), + status: File.exist?(File.join(File.dirname(meta_file), metadata['backup_file'])) ?
