- Add Claude OAuth authentication support with hybrid API key/OAuth flow
- Implement Docker container historical metrics in backend and charts API
- Add CEPH cluster data collection and new Ceph page
- Enhance RAID status display with detailed tooltips and visual indicators
- Fix host deduplication logic with Docker bridge IP filtering
- Fix NVMe temperature collection in host agent
- Add comprehensive test coverage for new features
- Improve frontend sparklines and metrics history handling
- Fix navigation issues and frontend reload loops
- Implement 'Show Problems Only' toggle combining degraded status, high CPU/memory alerts, and needs backup filters
- Add 'Investigate with AI' button to filter bar for problematic guests
- Fix dashboard column sizing inconsistencies between bars and sparklines view modes
- Fix PBS backups display and polling
- Refine AI prompt for general-purpose usage
- Fix frontend flickering and reload loops during initial load
- Integrate persistent SQLite metrics store with Monitor
- Fortify AI command routing with improved validation and logging
- Fix CSRF token handling for note deletion
- Debug and fix AI command execution issues
- Various AI reliability improvements and command safety enhancements
- Replace standard disk metric bar with StackedDiskBar in HostsOverview
- Show detailed per-disk usage breakdown on hover
- Use Portal for tooltips to ensure correct positioning and z-index
- Add class prop support to MetricBar
- Cap progress bars at 140px max-width for better readability
- Constrain shell layout to 1400px max-width, centered
- Fix metric columns (CPU, Memory, Disk) at 156px
- Give name/resource columns extra space via flex
- Remove Docker Disk column (data rarely available from API)
- Remove fixed percentage widths from backups table for auto-sizing
- Improve text contrast in progress bar labels
Use ResizeObserver to track container width and estimate text width
based on character count. When the full text (percentage + sublabel)
won't fit, only the percentage is shown to prevent text clipping.
- Implemented adaptive layout for NodeSummaryTable with responsive columns and sticky name column.
- Fixed GuestRow background display issues.
- Added IsLegacy field to Host and DockerHost models to flag legacy agents (version < 1.0.0).
- Updated monitor to populate IsLegacy based on agent version.
Add comprehensive sparkline chart support as an alternative to progress bars
for CPU, Memory, and Disk metrics across all tables.
Features:
- Toggle between bars/trends view modes (persisted to localStorage)
- 30-second sampling with 2-hour retention window using ring buffer
- Canvas-based rendering with shared requestAnimationFrame for efficiency
- Hover tooltips showing exact values and timestamps
- Threshold reference lines (warning/critical) for context
- localStorage persistence survives page refreshes (12-hour max age)
- Dynamic width adaptation to column size
- Namespaced resource IDs prevent collisions
- Lifecycle cleanup prevents memory leaks
Performance optimizations:
- Decoupled sampling from WebSocket handler (6x reduction in recording)
- O(1) ring buffer insertions (no array cloning)
- Batched canvas rendering (single rAF for all sparklines)
- Debounced localStorage writes
- Automatic pruning of removed resources
UI improvements:
- Consistent radio toggle styling matching other filters
- Fixed column widths prevent layout shift during toggle
- Fixed row heights prevent vertical size changes
- Sparklines fill available column width proportionally
