Implements comprehensive mdadm RAID array monitoring for Linux hosts
via pulse-host-agent. Arrays are automatically detected and monitored
with real-time status updates, rebuild progress tracking, and automatic
alerting for degraded or failed arrays.
Key changes:
**Backend:**
- Add mdadm package for parsing mdadm --detail output
- Extend host agent report structure with RAID array data
- Integrate mdadm collection into host agent (Linux-only, best-effort)
- Add RAID array processing in monitoring system
- Implement automatic alerting:
- Critical alerts for degraded arrays or arrays with failed devices
- Warning alerts for rebuilding/resyncing arrays with progress tracking
- Auto-clear alerts when arrays return to healthy state
**Frontend:**
- Add TypeScript types for RAID arrays and devices
- Display RAID arrays in host details drawer with:
- Array status (clean/degraded/recovering) with color-coded indicators
- Device counts (active/total/failed/spare)
- Rebuild progress percentage and speed when applicable
- Green for healthy, amber for rebuilding, red for degraded
**Documentation:**
- Document mdadm monitoring feature in HOST_AGENT.md
- Explain requirements (Linux, mdadm installed, root access)
- Clarify scope (software RAID only, hardware RAID not supported)
**Testing:**
- Add comprehensive tests for mdadm output parsing
- Test parsing of healthy, degraded, and rebuilding arrays
- Verify proper extraction of device states and rebuild progress
All builds pass successfully. RAID monitoring is automatic and best-effort
- if mdadm is not installed or no arrays exist, host agent continues
reporting other metrics normally.
Related to #676
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.
- 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)
This commit adds comprehensive token revocation tracking across the UI and enhances the agent installation script for better platform support.
Key changes:
- Added token revocation warnings in Docker hosts and host agents UI with amber-colored indicators
- Implemented automatic token revocation detection when tokens are deleted
- Enhanced install scripts with Unraid detection and manual start instructions for non-systemd platforms
- Improved service management with restart instead of start for systemd
- Added visual indicators for revoked tokens with contextual warnings
- Updated table column widths in hosts overview for better layout
- Hide Docker host sidebar when only 1 host is configured to save horizontal space
- Add keyboard auto-focus for search fields - typing anywhere on the page automatically focuses search
- Add ESC key support to clear search and unfocus input
- Fix vertical alignment of "+" icon in Docker Add Host button
Changed MetricBar type prop from conditional (value > 80 ? 'danger' : 'primary')
to semantic types ('cpu', 'memory', 'disk') for better maintainability and
consistency with the component's design system.
This allows MetricBar to handle threshold logic internally based on metric
type, rather than duplicating threshold conditions at each call site.
Windows Host Agent Enhancements:
- Implement native Windows service support using golang.org/x/sys/windows/svc
- Add Windows Event Log integration for troubleshooting
- Create professional PowerShell installation/uninstallation scripts
- Add process termination and retry logic to handle Windows file locking
- Register uninstall endpoint at /uninstall-host-agent.ps1
Host Agent UI Improvements:
- Add expandable drawer to Hosts page (click row to view details)
- Display system info, network interfaces, disks, and temperatures in cards
- Replace status badges with subtle colored indicators
- Remove redundant master-detail sidebar layout
- Add search filtering for hosts
Technical Details:
- service_windows.go: Windows service lifecycle management with graceful shutdown
- service_stub.go: Cross-platform compatibility for non-Windows builds
- install-host-agent.ps1: Full Windows installation with validation
- uninstall-host-agent.ps1: Clean removal with process termination and retries
- HostsOverview.tsx: Expandable row pattern matching Docker/Proxmox pages
Files Added:
- cmd/pulse-host-agent/service_windows.go
- cmd/pulse-host-agent/service_stub.go
- scripts/install-host-agent.ps1
- scripts/uninstall-host-agent.ps1
- frontend-modern/src/components/Hosts/HostsOverview.tsx
- frontend-modern/src/components/Hosts/HostsFilter.tsx
The Windows service now starts reliably with automatic restart on failure,
and the uninstall script handles file locking gracefully without requiring reboots.
