Windows 11 25H2 ships exclusively on ARM64 hardware. When users on ARM64
attempt to install the host agent, the Service Control Manager fails to
load the amd64 binary with ERROR_BAD_EXE_FORMAT, surfaced as "The Pulse
Host Agent is not compatible with this Windows version".
Changes:
- Dockerfile: Build pulse-host-agent-windows-arm64.exe alongside amd64
- Dockerfile: Copy windows-arm64 binary and create symlink for download endpoint
- install-host-agent.ps1: Use RuntimeInformation.OSArchitecture to detect ARM64
- build-release.sh: Build darwin-amd64, darwin-arm64, windows-amd64, windows-arm64
- build-release.sh: Package Windows binaries as .zip archives
- validate-release.sh: Check for windows-arm64 binary and symlink
- validate-release.sh: Add architecture validation for all darwin/windows variants
The installer now correctly detects ARM64 and downloads the appropriate binary.
Backend:
- Add IsEncryptionEnabled() method to ConfigPersistence
- Include encryption status in /api/notifications/health response
- Allows frontend to warn when credentials are stored in plaintext
Frontend:
- Update NotificationHealth type to include encryption.enabled field
- Frontend can now display warnings when encryption is disabled
This addresses the P2 requirement for encryption visibility, allowing
operators to know when notification credentials are not encrypted at rest.
Critical fixes (P0):
- Fix cooldown timing: Mark cooldown only after successful delivery, not before enqueue
- Add os.MkdirAll to queue initialization to prevent silent failures on fresh installs
- Add DNS re-validation at webhook send time to prevent DNS rebinding SSRF attacks
- Add SSRF validation for Apprise HTTP URLs
- Remove secret logging (bot tokens, routing keys) from debug logs
- Implement lastNotified cleanup to prevent unbounded memory growth
- Use shared HTTP client for webhooks to enable TLS connection reuse
- Add fallback to direct sending when queue enqueue fails
- Make queue worker concurrent (5 workers with semaphore) to prevent head-of-line blocking
- Fix webhook rate limiter race condition with separate mutex
- Fix email manager thread safety with mutex on rate limiter
- Fix grouping timer leak by adding stopCleanup signal
- Fix webhook 429 double sleep (use Retry-After OR backoff, not both)
Frontend improvements:
- Add queue/DLQ management API methods (getQueueStats, getDLQ, retryDLQItem, deleteDLQItem)
- Add getNotificationHealth and getWebhookHistory endpoints
- Add Apprise test support to NotificationTestRequest type
Related to notification system audit
- Add NOTIFICATION_AUDIT.md for system analysis
- Add NOTIFICATION_QUICK_REFERENCE.md for quick lookup
- Add NOTIFICATION_SYSTEM_MAP.md for architecture overview
- Fix tab panel missing rounded-tl corner when first tab is active
When updates complete quickly, the status API may return 'completed' before
the frontend detects the 'restarting' phase. This left users staring at a
frozen modal with no feedback, requiring manual page refresh.
Changes:
- When status is 'completed', immediately check /api/health
- If backend is healthy, reload the page to get new version
- If health check fails, assume restart in progress and start health polling
- Ensures users always get reloaded to the new version automatically
This fixes the UX issue reported in discussion #628 where the update modal
appeared frozen indefinitely despite successful update completion.
Changed .pulse-shell from fixed 95rem cap to fluid clamp(95rem, 92vw, 120rem)
to match standard monitoring dashboard behavior (Proxmox, Grafana, Portainer).
On laptops/small screens: unchanged (capped at 1520px)
On 1080p displays: expands to ~1766px usable width
On 4K/ultrawide: expands up to 1920px max for readability
Added back 2xl column widths (totaling ~1720px) that properly fit within
the expanded shell, giving wide-display users more breathing room while
maintaining proportional scaling across all breakpoints.
Changed files:
- index.css: Update .pulse-shell max-width to use clamp()
- Dashboard.tsx: Add 2xl column widths calculated for expanded shell
- GuestRow.tsx: Add matching 2xl column widths
Removed 2xl: width overrides that caused the table to exceed container width.
At ≥1536px viewport, the 2xl breakpoint expanded table columns to ~1528px
total width while .pulse-shell container provides only ~1416px usable space,
forcing Net In/Net Out columns off-screen and requiring horizontal scroll.
Table now caps at xl: breakpoint widths (~1266px) which fit comfortably within
the container at all viewport sizes. Net In/Net Out columns are now visible
without scrolling on 1080p, 4K, and all wide displays.
Changed files:
- Dashboard.tsx: Remove 2xl: width classes from all table header columns
- GuestRow.tsx: Remove 2xl: width classes from all table cell columns
Docker hosts with 'degraded' status were incorrectly appearing dimmed
(opacity-60) in the summary table, making them visually identical to
offline hosts. This was confusing because degraded hosts are still
actively reporting - they just have unhealthy containers or >35% of
containers not running.
The isHostOnline function now treats 'degraded' as an online status,
so these rows maintain full opacity. The status badge already provides
visual indication of the degraded state.
Addresses two issues preventing configuration backup/restore:
1. Export passphrase validation mismatch: UI only validated 12+ char
requirement when using custom passphrase, but backend always enforced
it. Users with shorter login passwords saw unexplained failures.
- Frontend now validates all passphrases meet 12-char minimum
- Clear error message suggests custom passphrase if login password too short
2. Import data parsing failed silently: Frontend sent `exportData.data`
which was undefined for legacy/CLI backups (raw base64 strings).
Backend rejected these with no logs.
- Frontend now handles both formats: {status, data} and raw strings
- Backend logs validation failures for easier troubleshooting
Related to #646 where user reported "error after entering password" with
no container logs. These changes ensure proper validation feedback and
make the backup system resilient to different export formats.
After the security hardening that introduced bootstrap token protection,
the first-run setup flow was broken because FirstRunSetup.tsx didn't
prompt users for the token. This caused a 401 "Bootstrap setup token
required" error during initial admin account creation.
Changes:
- Add dedicated unlock screen before the setup wizard
- Display instructions for retrieving token from host
- Include bootstrap token in quick-setup API request headers and body
- Only require unlock for first-run setup (skip in force mode)
The unlock screen follows the documented flow in README.md and ensures
only users with host access can configure an unconfigured instance.

The chart container was set to min-h-[12rem] (192px) on desktop while the SVG
was hardcoded to 128px, creating 64px of unwanted empty space. Changed container
to fixed h-32 (128px) to match the SVG height.
Removed CSS truncate from key identifier columns (container names, service names,
guest names, host names, image names) that were making data inaccessible on mobile/
touch devices where title tooltips don't work.
Users can now read full identifiers via horizontal scroll (already implemented via
ScrollableTable component). Data should always be readable without requiring additional
UI affordances.
Changed files:
- DockerUnifiedTable: Remove truncate from container/service names and images
- GuestRow: Remove truncate from guest names
- HostsOverview: Remove truncate from host display names and hostnames
Column resizing remains on backlog as optional enhancement; users should not need
a drag handle just to read the contents.
Resolves#641
## Problem
When a VM migrates between Proxmox nodes, Pulse was treating it as a new
resource and discarding custom alert threshold overrides. This occurred
because guest IDs included the node name (e.g., `instance-node-VMID`),
causing the ID to change when the VM moved to a different node.
Users reported that after migrating a VM, previously disabled alerts
(e.g., memory threshold set to 0) would resume firing.
## Root Cause
Guest IDs were constructed as:
- Standalone: `node-VMID`
- Cluster: `instance-node-VMID`
When a VM migrated from node1 to node2, the ID changed from
`instance-node1-100` to `instance-node2-100`, causing:
- Alert threshold overrides to be orphaned (keyed by old ID)
- Guest metadata (custom URLs, descriptions) to be orphaned
- Active alerts to reference the wrong resource ID
## Solution
Changed guest ID format to be stable across node migrations:
- New format: `instance-VMID` (for both standalone and cluster)
- Retains uniqueness across instances while being node-independent
- Allows VMs to migrate freely without losing configuration
## Implementation
### Backend Changes
1. **Guest ID Construction** (`monitor_polling.go`):
- Simplified to always use `instance-VMID` format
- Removed node from the ID construction logic
2. **Alert Override Migration** (`alerts.go`):
- Added lazy migration in `getGuestThresholds()`
- Detects legacy ID formats and migrates to new format
- Preserves user configurations automatically
3. **Guest Metadata Migration** (`guest_metadata.go`):
- Added `GetWithLegacyMigration()` helper method
- Called during VM/container polling to migrate metadata
- Preserves custom URLs and descriptions
4. **Active Alerts Migration** (`alerts.go`):
- Added migration logic in `LoadActiveAlerts()`
- Translates legacy alert resource IDs to new format
- Preserves alert acknowledgments across restarts
### Frontend Changes
5. **ID Construction Updates**:
- `ThresholdsTable.tsx`: Updated fallback from `instance-node-vmid` to `instance-vmid`
- `Dashboard.tsx`: Simplified guest ID construction
- `GuestRow.tsx`: Updated `buildGuestId()` helper
## Migration Strategy
- **Lazy Migration**: Configs are migrated as guests are discovered
- **Backwards Compatible**: Old IDs are detected and automatically converted
- **Zero Downtime**: No manual intervention required
- **Persisted**: Migrated configs are saved on next config write cycle
## Testing Recommendations
After deployment:
1. Verify existing alert overrides still apply
2. Test VM migration - confirm thresholds persist
3. Check guest metadata (custom URLs) survive migration
4. Verify active alerts maintain acknowledgment state
## Related
- Addresses similar issues with guest metadata and active alert tracking
- Lays groundwork for any future guest-specific configuration features
- Aligns with project philosophy: correctness and UX over implementation complexity

- Add GPU field to Temperature model with edge, junction, and mem sensors
- Add amdgpu chip recognition to temperature parser
- Implement parseGPUTemps() to extract AMD GPU temperature data
- Update frontend TypeScript types to include GPU temperatures
- Display GPU temps in node table tooltip alongside CPU temps
- Set hasGPU flag when GPU data is available
This enables temperature monitoring for AMD GPUs (amdgpu sensors)
that was previously being collected via SSH but silently discarded
during parsing.
This implements the ability for users to assign custom display names to Docker hosts,
similar to the existing functionality for Proxmox nodes. This addresses the issue where
multiple Docker hosts with identical hostnames but different IPs/domains cannot be
easily distinguished in the UI.
Backend changes:
- Add CustomDisplayName field to DockerHost model (internal/models/models.go:201)
- Update UpsertDockerHost to preserve custom display names across updates (internal/models/models.go:1110-1113)
- Add SetDockerHostCustomDisplayName method to State for updating names (internal/models/models.go:1221-1235)
- Add SetDockerHostCustomDisplayName method to Monitor (internal/monitoring/monitor.go:1070-1088)
- Add HandleSetCustomDisplayName API handler (internal/api/docker_agents.go:385-426)
- Route /api/agents/docker/hosts/{id}/display-name PUT requests (internal/api/docker_agents.go:117-120)
Frontend changes:
- Add customDisplayName field to DockerHost TypeScript interface (frontend-modern/src/types/api.ts:136)
- Add MonitoringAPI.setDockerHostDisplayName method (frontend-modern/src/api/monitoring.ts:151-187)
- Update getDisplayName function to prioritize custom names (frontend-modern/src/components/Settings/DockerAgents.tsx:84-89)
- Add inline editing UI with save/cancel buttons in Docker Agents settings (frontend-modern/src/components/Settings/DockerAgents.tsx:1349-1413)
- Update sorting to use custom display names (frontend-modern/src/components/Docker/DockerHosts.tsx:58-59)
- Update DockerHostSummaryTable to display custom names (frontend-modern/src/components/Docker/DockerHostSummaryTable.tsx:40-42, 87, 120, 254)
Users can now click the edit icon next to any Docker host name in Settings > Docker Agents
to set a custom display name. The custom name will be preserved across agent reconnections
and takes priority over the hostname reported by the agent.

When authentication is not configured (hasAuth() returns false), the
Settings tab is now automatically hidden from the web interface. This
provides a cleaner monitoring-only view for unauthenticated deployments
where users only need to check the health of their environment.
The Settings icon beside the Alerts tab will only appear when
authentication is properly configured via PULSE_AUTH_USER/PASS,
API tokens, proxy auth, or OIDC.
Changes:
- Modified utilityTabs in App.tsx to conditionally include Settings
based on hasAuth() signal
- Updated CONFIGURATION.md to document this UI behavior
Addresses issue #567 where selecting "Custom interval..." from the
backup polling dropdown would revert to a preset option if the current
custom minutes value happened to match a predefined interval.
The bug occurred because:
1. User selects "Custom interval..." from dropdown
2. Code sets interval based on current customMinutes value
3. If that value matches a preset (e.g., 60 min = 1 hour), the
computed select value returns the preset instead of 'custom'
4. Dropdown reverts, hiding the custom input field
Fix introduces a dedicated state variable (backupPollingUseCustom)
to explicitly track whether custom mode is active, independent of
whether the current interval value matches a preset option.
Changes:
- Add backupPollingUseCustom signal to track custom mode state
- Update backupIntervalSelectValue() to check custom flag first
- Set/clear custom flag in dropdown onChange handler
- Initialize custom flag when loading settings from API

This change adds support for custom SSH ports when collecting temperature
data from Proxmox nodes, resolving issues for users who run SSH on non-standard
ports.
**Why SSH is still needed:**
Temperature monitoring requires reading /sys/class/hwmon sensors on Proxmox
nodes, which is not exposed via the Proxmox API. Even when using API tokens
for authentication, Pulse needs SSH access to collect temperature data.
**Changes:**
- Add `sshPort` configuration to SystemSettings (system.json)
- Add `SSHPort` field to Config with environment variable support (SSH_PORT)
- Add per-node SSH port override capability for PVE, PBS, and PMG instances
- Update TemperatureCollector to accept and use custom SSH port
- Update SSH known_hosts manager to support non-standard ports
- Add NewTemperatureCollectorWithPort() constructor with port parameter
- Maintain backward compatibility with NewTemperatureCollector() (uses port 22)
- Update frontend TypeScript types for SSH port configuration
**Configuration methods:**
1. Environment variable: SSH_PORT=2222
2. system.json: {"sshPort": 2222}
3. Per-node override in nodes.enc (future UI support)
**Default behavior:**
- Defaults to port 22 if not configured
- Maintains full backward compatibility
- No changes required for existing deployments
The implementation includes proper ssh-keyscan port handling and known_hosts
management for non-standard ports using [host]:port notation per SSH standards.
Added explicit onKeyDown handler to stop event propagation when Enter
is pressed in the ignored container prefixes textarea. This ensures
newlines can be properly entered to separate multiple prefixes.

When authentication expires after some time, users see "Connection lost"
and must refresh the page to see "Authentication required". This commit
implements automatic redirect to login when authentication expires.
Changes:
- Add authentication check to WebSocket endpoint to prevent unauthenticated
WebSocket connections
- Handle WebSocket close with code 1008 (policy violation) as auth failure
and redirect to login
- Intercept 401 responses on API calls (except initial auth checks) and
automatically redirect to login page
- Clear stored credentials and set logout flag before redirect to ensure
clean login flow
This provides a better user experience by immediately redirecting to the
login page when the session expires, rather than showing a confusing
"Connection lost" message that requires manual page refresh.
Improves user experience when physical disks don't appear by providing
clear, context-aware instructions. The empty state now shows:
- When no PVE nodes are configured: prompt to add nodes
- When nodes exist but no disks appear: step-by-step requirements
including enabling SMART monitoring in both Pulse and Proxmox
This addresses confusion from issue #594 where users didn't realize
they needed to enable SMART monitoring in Proxmox itself (not just
in Pulse settings) and wait 5 minutes for data collection.

Add optional GuestURL field to PVE instances and cluster endpoints,
allowing users to specify a separate guest-accessible URL for web UI
navigation that differs from the internal management URL.
Backend changes:
- Add GuestURL field to PVEInstance and ClusterEndpoint structs
- Add GuestURL field to Node model
- Update cluster auto-discovery to preserve existing GuestURL values
- Update node creation logic to populate GuestURL from config
- Update API handlers to accept and persist GuestURL field
Frontend changes:
- Add GuestURL input field to NodeModal for configuration
- Update NodeGroupHeader and NodeSummaryTable to use GuestURL for navigation
- Add GuestURL to Node and PVENodeConfig TypeScript interfaces
When GuestURL is configured, it will be used for navigation links
instead of the Host URL, allowing users to access PVE hosts through
a reverse proxy or different domain while maintaining internal API
connections.

Enhanced the PMG connection test to actually validate the metrics
endpoints that Pulse uses for monitoring, rather than only checking
the version endpoint. This provides users with immediate feedback if
their PMG credentials lack the necessary permissions to collect metrics.
Backend changes:
- Test mail statistics, cluster status, and quarantine endpoints during
connection test (internal/api/config_handlers.go:1695-1714)
- Return warnings array in test response when endpoints are unavailable
- Increased timeout from 10s to 15s to accommodate multiple endpoint checks
- Added warning logs for failed endpoint checks
Frontend changes:
- Added showWarning() toast function for warning messages
- Enhanced NodeModal to display warning status with amber styling
- Added warnings list display in test results UI
- Updated Settings.tsx to show warnings from connection tests
This change helps users identify permission issues immediately rather
than discovering later that metrics aren't being collected despite a
"successful" connection.
- Build host agent binaries for all platforms (linux/darwin/windows, amd64/arm64/armv7) in Docker
- Add Makefile target for building agent binaries locally
- Add startup validation to check for missing agent binaries
- Improve download endpoint error messages with troubleshooting guidance
- Enhance host details drawer layout with better organization and visual hierarchy
- Update base images to rolling versions (node:20-alpine, golang:1.24-alpine, alpine:3.20)
- Add flex-1 to all drawer cards for consistent space filling
- Implement single-drawer-open behavior (accordion-style)
- Add text truncation to labels and IP badges to prevent overflow
- Replace Map-based state with reactive signals for better performance
This commit implements per-node temperature monitoring control and fixes a critical
bug where partial node updates were destroying existing configuration.
Backend changes:
- Add TemperatureMonitoringEnabled field (*bool) to PVEInstance, PBSInstance, and PMGInstance
- Update monitor.go to check per-node temperature setting with global fallback
- Convert all NodeConfigRequest boolean fields to *bool pointers
- Add nil checks in HandleUpdateNode to prevent overwriting unmodified fields
- Fix critical bug where partial updates zeroed out MonitorVMs, MonitorContainers, etc.
- Update NodeResponse, NodeFrontend, and StateSnapshot to include temperature setting
- Fix HandleAddNode and test connection handlers to use pointer-based boolean fields
Frontend changes:
- Add temperatureMonitoringEnabled to Node interface and config types
- Create per-node temperature monitoring toggle handler with optimistic updates
- Update NodeModal to wire up per-node temperature toggle
- Add isTemperatureMonitoringEnabled helper to check effective monitoring state
- Update ConfiguredNodeTables to show/hide temperature badge based on monitoring state
- Update NodeSummaryTable to conditionally show temperature column
- Pass globalTemperatureMonitoringEnabled prop through component tree
The critical bug fix ensures that when updating a single field (like temperature
monitoring), the backend only modifies that specific field instead of zeroing out
all other boolean configuration fields.
- Add Access-Control-Expose-Headers to allow frontend to read X-CSRF-Token response header
- Implement proactive CSRF token issuance on GET requests when session exists but CSRF cookie is missing
- Ensures frontend always has valid CSRF token before making POST requests
- Fixes 403 Forbidden errors when toggling system settings
This resolves CSRF validation failures that occurred when CSRF tokens expired or were missing while valid sessions existed.
Extends the Docker monitoring and alerting system to track writable layer
usage as a percentage of the container's root filesystem. This helps
identify containers with bloated copy-on-write layers before they
consume excessive disk space.
- Add disk threshold to DockerThresholdConfig (default: 85% trigger, 80% clear)
- Evaluate disk alerts for running containers when RootFilesystemBytes > 0
- Include disk metadata (writable layer, total filesystem, block I/O stats)
- Update frontend to display and configure disk thresholds
- Add test coverage for disk usage alert hysteresis
- Document disk monitoring in DOCKER_MONITORING.md
Per-container and per-host overrides apply to disk thresholds the same
way they do for CPU and memory.
This commit addresses multiple issues in the Docker/host agent removal flow:
Agent Stop Fix:
- Add systemctl stop command after agent acknowledgement to prevent systemd restart
- Previous behavior: agent disabled but systemd immediately restarted it (Restart=always)
- New behavior: agent disables itself, sends ack, then stops systemd service completely
UX Improvements:
- Add real-time elapsed time counter during removal wait
- Show progress indicators prominently (no longer hidden in dropdown)
- Display expected time range (30-60 seconds) and last heartbeat
- Auto-show timeout warning after 2 minutes with actionable "Force remove" button
- Add contextual help explaining what's happening at each stage
Security Enhancement:
- Automatically revoke API tokens when removing Docker/host agents
- Previous behavior: tokens remained valid after agent removal
- New behavior: tokens are revoked and persisted immediately on removal
- Prevents removed agents from re-authenticating with old credentials
Extends Docker container monitoring with comprehensive disk and storage information:
- Writable layer size and root filesystem usage displayed in new Disk column
- Block I/O statistics (read/write bytes totals) shown in container drawer
- Mount metadata including type, source, destination, mode, and driver details
- Configurable via --collect-disk flag (enabled by default, can be disabled for large fleets)
Also fixes config watcher to consistently use production auth config path instead of following PULSE_DATA_DIR when in mock mode.
Optimistically update local and parent state before the API call completes, so the external link icon appears instantly when the user saves a URL. If the API fails, the state reverts automatically.
Before: Link icon appeared after API response (~100-500ms delay)
After: Link icon appears immediately with smooth fade-in animation
Implements clickable name field with inline URL editor for Docker resources, matching the Proxmox guest URL feature:
- Create DockerMetadataAPI for storing custom URLs
- Add metadata loading and caching in DockerHosts component
- Add URL editing UI to DockerContainerRow and DockerServiceRow
- Global editing state prevents multiple simultaneous edits
- Shows external link icon when URL is set
- Supports Enter to save, Escape to cancel
- Toast notifications for save/delete operations
- Stores metadata with format: {hostId}:container:{containerId}
Allows users to add quick links to container/service dashboards (e.g., Portainer, Traefik, internal UIs).
Change vertical padding from py-1 to py-0.5 on all data cells to match Proxmox guest table row heights for visual consistency across both monitoring interfaces.
Remove redundant colored status dots from Docker container and service rows to align with Proxmox guest table design. Status is already clearly indicated by the Status column badge.
Match Proxmox behavior by dimming stopped containers and degraded services with opacity-60, and showing dashes for metrics (CPU, memory, uptime, restarts) when containers are not running.
The Type column was too narrow at 8%, causing Service and Container badges to be truncated. Increased to 11% and redistributed space from other columns to maintain 100% total width.
