- Ceph: Complete rework with summary cards (storage, clusters, services, pools),
search with type-to-search, proper loading/disconnected/empty states, cluster
overview table, pools table with filtering, health badges with tooltips
- Replication: Add summary cards (total/healthy/issues/next sync), status filter
buttons (All/Healthy/Warning/Error), search with type-to-search, countdown timers
for next sync with overdue/imminent highlighting, row highlighting for problem jobs,
error tooltips, loading state
- Mail Gateway: Add aggregate summary cards across all instances (mail/spam/virus/
quarantine/queue), visual threat rate progress bars, status badges with health
indicators, queue depth tooltips with breakdown, streamlined stats grid with
color-coded threat categories, improved cluster nodes table
All three pages now follow the same design patterns as Dashboard, Hosts, Docker,
and Storage using Card, EmptyState, and consistent styling.
- Add sortable headers to Clusters and Nodes views
- Add ColumnPicker dropdown for Pods view (toggle Namespace, Cluster, Ready, Restarts, Image, Age columns)
- Column visibility persists to localStorage
- Sorting persists across sessions for all views
- Add sortable table headers for Pod and Deployment views
- Click column headers to toggle sort direction
- Sort state persists across sessions
- Add namespace dropdown filter for Pods/Deployments views
- Auto-populates from available namespaces
- Include namespace filter in reset and active filters check
Backend:
- Seed OCI classification from previous state so containers never
'downgrade' to LXC if config fetching intermittently fails
- Prevent type regression in recordGuestSnapshot when OCI was previously detected
- Move metrics zeroing before snapshot recording for cleaner flow
Frontend:
- Add isOCIContainer() memo that checks both type and isOci flag
- Use isOCI helper in Dashboard.tsx for AI context building
- Include oci-container type in useResources container conversion
- Preserve isOci and osTemplate fields through legacy conversion
This ensures OCI containers retain their classification even when
Proxmox API permissions or transient errors prevent config reads.
- Frontend: Add ociImage memo to extract clean image name from osTemplate
- Frontend: Show OCI image name in type badge tooltip
- Frontend: Display OCI image in OS column when no guest agent info available
- Frontend: Include ociImage in AI context data for selected OCI containers
- Backend: Differentiate OCI containers as 'oci_container' type in AI context
- Backend: Add Metadata field to ResourceContext for extensibility
- Backend: Include oci_image in container metadata for AI analysis
- Backend: Update section heading to 'LXC/OCI Containers' in AI context
This follows Docker container patterns to avoid duplicating work.
- Backend: Add IsOCI and OSTemplate fields to Container model
- Backend: Add extractContainerOSTemplate() and isOCITemplate() detection functions
- Backend: Detect OCI containers via ostemplate config and set type to 'oci'
- Frontend: Add isOci and osTemplate to Container interface
- Frontend: Add 'oci-container' to ResourceType with distinct purple badge
- Frontend: Update Dashboard filters to include OCI containers with LXC
- Tests: Add comprehensive unit tests for OCI detection logic
OCI containers are detected by checking the ostemplate for patterns like:
- oci: prefix (e.g., oci:docker.io/library/alpine:latest)
- docker: prefix (e.g., docker:nginx:latest)
- Known registry URLs (docker.io, ghcr.io, gcr.io, quay.io, etc.)
- Local templates with oci- or oci_ filename patterns
- Add DOMPurify sanitization for AI chat markdown rendering (XSS fix)
- Configure DOMPurify to add target=_blank and rel=noopener to links
- Update system prompt to align with command approval policy
- Clarify safe vs destructive commands in prompt
- Improve patrol auto-fix mode guidance with safe operation list
- Add verification requirements for auto-fix actions
- Update observe-only mode to be clearer about read-only restrictions
UX improvement: The Auto-Fix Model dropdown was too far from the
Patrol Auto-Fix toggle, making it hard to find.
Now the flow is:
1. Scroll to 'AI Patrol Behavior' section
2. Check the acknowledgement checkbox
3. Enable 'Patrol Auto-Fix' toggle
4. Model selector appears RIGHT BELOW the toggle
The model dropdown only appears when auto-fix is enabled (since
it's irrelevant otherwise).
Add collapsible panel to display AI-learned intelligence:
Features:
- Failure predictions with time estimates
- Color-coded severity (overdue=red, <3 days=amber, etc.)
- Human-readable event types and confidence percentages
- Resource dependency/correlation display
- Shows source → target relationships with avg delay
- Expandable/collapsible design to save space
Styling:
- Purple gradient theme consistent with AI branding
- Responsive with dark mode support
- Clean card-based layout for predictions
- Badge showing total insight count
Ready to integrate into Alerts page or resource details.
Add configurable model specifically for automatic remediation actions:
Backend (internal/config/ai.go):
- Add AutoFixModel field to AIConfig
- Add GetAutoFixModel() getter with fallback chain:
AutoFixModel -> PatrolModel -> Model
Frontend (AISettings.tsx, types/ai.ts):
- Add auto_fix_model to AISettings types
- Add Auto-Fix Model dropdown (only shows when patrol_auto_fix enabled)
- Falls back to patrol model if not set
API (ai_handlers.go):
- Add auto_fix_model to response and update request
- Handle saving/loading the new field
Rationale:
- Auto-fix takes real actions, may warrant a more capable model
- Patrol observation can use cheaper models for cost savings
- Gives users granular control over model costs vs reliability
- Model hierarchy: Chat > AutoFix > Patrol > Default
When there's only 1 day of AI usage data, the sparkline was invisible
because a single point draws at x=0 with no width. Now draws a
horizontal line across the full width so users can see the value.
This happens when AI has just been enabled and there's only one
day of recorded usage so far.
Phase 2 of Pulse AI differentiation:
- Create internal/ai/baseline package for learned baselines
- Implement statistical baseline learning with mean, stddev, percentiles
- Add z-score based anomaly detection with severity classification
(low, medium, high, critical based on standard deviations)
- Integrate baseline provider into context builder
- Wire baseline store into patrol service with adapters
- Add anomaly enrichment to resource contexts
Key features:
- Learn computes baseline from historical metric data points
- IsAnomaly and CheckAnomaly detect deviations from normal
- Persists baselines to disk as JSON for durability
- Formatted anomaly descriptions for AI consumption
Example: 'Memory is high above normal (85.2% vs typical 42.1% ± 8.3%)'
The baseline store needs to be initialized and triggered to learn
from metrics history. Next step is adding the learning loop.
All tests passing.
- Add exponential backoff retry for Docker agent startup (main.go)
- Fix Docker resource/image column widths with proper truncation
- Unify IP tooltip styling across hosts and guests with detailed network info
- Improve column visibility defaults and sticky column handling
- Various component refinements for Dashboard, Storage, and Backups views
- Changed patrol schedule from preset dropdown to freeform number input
- Users can now set any interval (min 10 minutes, max 7 days, or 0 to disable)
- Added patrol_interval_minutes to API request/response (preset is now deprecated)
- Backend validates: min 10 minutes when enabled, max 10080 (7 days)
- Frontend shows human-readable duration next to input (e.g., '6h', '2h 30m')
Also improved Auto-Fix Mode safety:
- Removed '(recommended)' from preset options (was subjective)
- Added 'I understand the risks' acknowledgement checkbox
- Toggle is disabled until user explicitly acknowledges the risks
- Shows prominent warning when Auto-Fix is enabled
- Acknowledgement is session-based (must re-acknowledge on page reload)
- Add 'content' type to StreamDisplayEvent for tracking text chunks
- Track content events in streamEvents array for chronological display
- Update render to use Switch/Match for cleaner conditional rendering
- Interleave thinking, tool calls, and content as they stream in
- Add fallback for old messages without streamEvents for backwards compat
Previously, tool/command outputs stayed at top while AI text responses
accumulated at the bottom. Now all events appear in order like a
normal chatbot.
- Remove model references from provider labels ('OpenAI' not 'OpenAI (GPT-4)')
- Remove DEFAULT_MODELS usage in form initialization
- Use generic placeholders instead of specific model names
- Models are now fetched dynamically from each provider's API
- UI won't become outdated when new models are released
- Show number of configured providers and available models
- Display friendly model name (without provider prefix)
- Better status message: 'Ready • 1 10 models'provider
- Adds 'Refresh Models' button next to Default Model label
- Spinning icon animation during loading
- Allows manual refresh after configuring new providers
- Add clear_anthropic_key, clear_openai_key, clear_deepseek_key, clear_ollama_url flags to API
- Backend handles clearing with confirmation prompt

- Clear button requires confirmation before removing credentials
- Frontend automatically refreshes settings after clearing
- Add /api/ai/test/{provider} endpoint for testing individual providers
- Add 'Test' button to each provider accordion (visible when configured)
- Shows test result inline (success/error message)
- Update help links with direct URLs to API key pages:
- Anthropic: console.anthropic.com/settings/keys
- OpenAI: platform.openai.com/api-keys
- DeepSeek: platform.deepseek.com/api_keys
- Ollama: ollama.ai
Backend:
- Add per-provider API key fields to AIConfig (AnthropicAPIKey, OpenAIAPIKey, DeepSeekAPIKey, OllamaBaseURL, OpenAIBaseURL)
- Add NewForProvider() and NewForModel() factory functions for multi-provider instantiation
- Update ListModels() to aggregate models from all configured providers with provider:model format
- Update Execute/ExecuteStream to dynamically create provider based on selected model
- Update TestConnection to use multi-provider aware provider creation
- Add helper functions: HasProvider(), GetConfiguredProviders(), GetAPIKeyForProvider(), GetBaseURLForProvider(), ParseModelString(), FormatModelString()
Frontend:

- Enhance AIChat with patrol status and manual trigger controls
- Add resource store improvements for AI context building
- Expand Alerts page with AI-powered analysis integration
- Add Vite proxy config for AI API endpoints
- Support both Anthropic and OpenAI providers with streaming
Keep only the simple AI-powered approach:
- set_resource_url tool lets AI save discovered URLs
- Users ask AI directly: 'Find URLs for my containers'
- AI uses its intelligence to discover and set URLs
Removed:
- URLDiscoveryService (rigid port scanning)
- Bulk discovery API endpoints
- Frontend discovery button
The AI itself is smart enough to iterate through resources
and discover URLs when asked.
- Add host metadata API for custom URL editing on hosts page
- Enhance AI routing with unified resource provider lookup

- Add comprehensive test coverage for new features
- Improve frontend sparklines and metrics history handling
- Fix navigation issues and frontend reload loops
Replaced 18+ console.log statements in AI-related files with
logger.debug/warn/error calls. This ensures debug output only
appears in development mode, keeping production logs clean.
Files updated:
- frontend-modern/src/api/ai.ts (15 statements)
- frontend-modern/src/components/AI/AIChat.tsx (4 statements)
This cleanup addresses transition debt from the unified resources migration:
Frontend cleanup:
- Move all Resource→Legacy type conversions to useResourcesAsLegacy() hook
- Add asNodes() and asDockerHosts() adapter functions to the hook
- Simplify DockerRoute, HostsRoute, DashboardView to use the centralized hook
- Remove ~300 lines of duplicated adapter code from App.tsx
- Remove debug console.log statements from Dashboard.tsx
- Fix CPU value conversion (divide by 100) for Dashboard compatibility
Backend fixes (from previous session):
- Fix parentID format in converters (VM, Container, Storage) to match Node.ID
- Format changed from 'instance/node/nodename' to 'instance-nodename'
- Update tests to match new parentID format
This consolidates all legacy type conversion logic in one place,
making future cleanup easier when components are migrated to use
unified resources directly.
- Removed /resources page and associated frontend components
- Removed ResourcesOverview.tsx, UnifiedResourceRow.tsx, columns.ts
- Removed frontend types/resource.ts
- Updated unified-resource-architecture.md to mark Phase 4 as ABANDONED
- Removed unified-view-migration-plan.md
- Backend unified resource model remains for AI context
This is a checkpoint before attempting full frontend migration to unified model.
This implements Phase 4 of the Unified Resource Architecture - the frontend
unified resources view.
New Features:
- Unified resources page at /resources route
- Fetches from /api/resources REST endpoint
- Auto-refreshes every 10 seconds
- Filtering by search, type, platform, status
- Grouping by type, platform, or parent
- Status indicators with alert badges
- CPU/Memory/Disk progress bars
Files Added:
- frontend-modern/src/types/resource.ts - TypeScript types matching Go backend
- frontend-modern/src/components/Resources/ResourcesOverview.tsx - Main component
Files Modified:
- frontend-modern/src/App.tsx - Added lazy import and route for ResourcesOverview
- .gemini/docs/unified-resource-architecture.md - Updated Phase 4 status
Access the unified view by navigating to /resources directly.
The route is not yet in the main navigation (power user feature).
- Extended AI context selection to host rows in HostsOverview

- 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
Simplified OS display to plain "Windows" and "Linux" text labels.
Previous icon attempts were rejected as too complex or unclear.
Text labels are cleaner and more universally recognizable.
- Extract ostype from LXC container config (debian, ubuntu, alpine, etc.)
- Map ostype values to human-readable names (e.g., "debian" -> "Debian")
- Add OSName field to Container model and ContainerFrontend
- Add icons for NixOS, openSUSE, and Gentoo in frontend
- LXC containers now show OS icons alongside VMs in the dashboard
Supported LXC OS types: alpine, archlinux, centos, debian, devuan,
fedora, gentoo, nixos, opensuse, ubuntu, unmanaged
- Add OSInfoCell component with OS-specific icons (Windows, Ubuntu,
Debian, Alpine, CentOS/RHEL, Fedora, Arch, FreeBSD, generic Linux)
- Each OS type has a distinct color for quick visual identification
- Portal tooltip shows full OS name, version, and guest agent version
- Much more compact than text strings like "Microsoft Windows Server 2022"
OS info requires guest agent to be installed and configured, so most
guests won't have this data. Move to detailed tier so it only shows
on extra-wide screens or when explicitly enabled by user.
- Add checkmark icon for fresh backups
- Add warning triangle for stale backups
- Add X icon for critical/never backups
- Use consistent Portal-based tooltip matching other columns
- Show formatted date, time, and relative age in tooltip
Replace drawer-based info display with inline columns that can be toggled:
- Add IP, Uptime, Node, Backup, OS, Tags columns (user-toggleable)
- Add ColumnPicker dropdown to show/hide columns with localStorage persistence
- Columns auto-show based on screen width using priority system
- Remove GuestDrawer - all info now visible inline or via tooltips
Rich hover tooltips:
- Disk bar: Shows all mount points with usage %, color-coded by severity
- Memory bar: Shows used/free/balloon/swap breakdown
- IP column: Shows network icon + count, hover for interfaces, MACs, IPs, traffic
Also:
- Create useColumnVisibility hook for responsive column management
- Create ColumnPicker component for column toggle UI
- Update drawer layouts in Hosts/Docker tabs for consistency
The StatusDot component was computing variant, size, and className once
at mount time, not reactively. When a VM transitioned from stopped to
running, the tooltip updated (it accessed props.title directly) but the
dot color stayed red because className was stale.
Fix: Convert plain variable assignments to getter functions that access
props reactively, and call them in the JSX template.
- Add AI service with Anthropic, OpenAI, and Ollama providers
- Add AI chat UI component with streaming responses
- Add AI settings page for configuration
- Add agent exec framework for command execution
- Add API endpoints for AI chat and configuration
The max-width:0 CSS trick from d3f22f06 caused the resource column
content to overlap with the TYPE badge. Use a proper max-w-[300px]
class instead to constrain long container names while maintaining
proper column spacing.
Related to #810, #789
The test was using getByRole('checkbox') which now matches multiple
elements after adding the "Skip certificate verification" checkbox.
Use name matcher to select the specific Docker monitoring checkbox.
Adds a checkbox in Settings → Host Agents that enables insecure mode for
users running Pulse behind self-signed HTTPS certificates.
When enabled:
- Adds -k flag to curl commands for downloading the install script
- Adds --insecure flag to the agent for connecting back to Pulse
Related to #806
Add max-width constraint to the resource column in the Docker table to
ensure very long container names (like Kubernetes UUID-based names) are
properly truncated instead of extending the table width.
Related to #789
When new nodes are added to a Proxmox cluster after Pulse was
initially configured, they weren't showing up in Settings. The
existing "Refresh" button only triggered network discovery, not
cluster membership re-detection.
Changes:
- Add POST /api/config/nodes/{id}/refresh-cluster endpoint
- Add "Refresh" button in cluster node panel in Settings
- Re-detect cluster membership and update stored endpoints
Related to #799
StackedMemoryBar.tsx:
- Fixed 'props.balloon' possibly undefined error by adding fallback
to second comparison in Show condition
Settings.tsx:
- Fixed 'systemSettings' scope error by using updateChannel() signal
instead of referencing out-of-scope variable from previous try block
Both files now pass strict TypeScript checks.
Changed from warning (amber) to danger (red) tone and added:
- Dynamic description based on reconnecting status
- Manual "Reconnect now" button when not auto-reconnecting
- Consistent "Connection lost" title
All 7 major pages now have unified connection lost UX:
Dashboard, Storage, Backups, Replication, Hosts, Docker, Mail Gateway
Docker/Containers page now shows a clear error state when WebSocket
connection is lost, with a manual "Reconnect now" button. This
matches the pattern established across all other major pages.
Connection lost UX is now consistent across: Dashboard, Storage,
Backups, Replication, Hosts, and Docker.
Hosts page now shows a clear error state when WebSocket connection
is lost, with a manual "Reconnect now" button. Also improved loading
state logic to differentiate between initial loading and connection
loss after having received data.
This completes the connection lost UX consistency across all major
pages: Dashboard, Storage, Backups, Replication, and now Hosts.
Both pages now show a consistent disconnect state with:
- Dynamic description based on reconnecting status
- Manual "Reconnect now" button when not auto-reconnecting
This matches the Dashboard and Storage page behavior, providing a
consistent UX across all main pages when connection is lost.
Storage page now shows a clear error state when WebSocket connection
is lost, matching the Dashboard's behavior. Users see the issue and
can manually reconnect instead of wondering why data isn't updating.
The sidebar no longer persists its collapsed state to localStorage.
Each visit to Settings starts with the sidebar expanded, showing
all menu labels for better discoverability by new users.
Users can still collapse the sidebar during their session if they
want more space, but it will reset to expanded on page reload.

Add a new filter button that shows only guests with stale, critical,
or missing backups. This makes it easy to identify which VMs and
containers need attention for backup scheduling.
- Adds backupMode state with 'all' and 'needs-backup' options
- Filters out templates (they don't need backups)
- Uses existing getBackupInfo() thresholds (>24h stale, >72h critical)
- Integrates with Reset button and Escape key handling
- Persists filter state in localStorage
Related to #762
The previous fix (2078421d) added overflow-hidden but didn't address
the root cause: the drawer div inside overflow-x-auto context had no
width constraint, so flex-wrap saw infinite space and didn't wrap.
Adding w-0 min-w-full forces the div to take exactly 100% of parent
width, which properly constrains flex-wrap to wrap cards within the
visible viewport.
Related to #789
Track previously seen host types and preserve them when one data source
temporarily has no entry for a hostname. This prevents the "Host" or
"Docker" type badge from disappearing and reappearing when websocket
updates cause momentary state inconsistencies.
The fix only preserves types if the corresponding source array has any
data at all, ensuring that intentional host removal (both arrays empty
for that host) still works correctly.
Related to #773
The Update Channel dropdown reverted to "stable" after saving because the
frontend was overwriting the user's saved preference with the running
version's channel. Now the saved setting takes priority over the detected
channel.
Related to #738
The StackedMemoryBar component was incorrectly calculating segments when
Proxmox balloon was set to maxmem (no actual ballooning). In this case:
- balloon = total (e.g., 32GB)
- used = actual memory (e.g., 20GB)
- active = used - balloon = 20GB - 32GB = 0 (clamped)
- balloonPercent = 32GB/32GB * 100 = 100%
This caused the bar to always show 100% yellow (balloon) even when the
actual memory usage was much lower.
Fixed by only showing balloon segment when actual ballooning is in effect
(balloon > 0 && balloon < total). When there's no ballooning, the bar
now correctly shows used memory as green with the actual percentage.
Related to #788
The expanded container/service drawer cards were overflowing
horizontally instead of wrapping when the table had overflow-x-auto.
Adding overflow-hidden to the drawer's outer container forces the
flex-wrap to work correctly.
Related to #789
The StackedMemoryBar component was using flex layout for segments,
but flex children grow by default regardless of percentage width.
Changed to absolute positioning (like MetricBar uses) so the width
percentages actually work as expected.
Related to #788

Revert expanded width from w-64 (256px) to w-72 (288px) and min/max
from 16rem to 18rem. The reduction in commit 6333a445 caused PVE node
status icons to wrap to two lines.
