The agent gate only allowed temperature collection on Linux (lm-sensors).
FreeBSD exposes CPU and ACPI thermal zone temperatures via sysctl
(dev.cpu.N.temperature, hw.acpi.thermal.tzN.temperature). Parse sysctl
output directly in Go without shell involvement.
The --disk-exclude agent flag only filtered local metric collection but
had no effect on server-side Proxmox disk health and SSD wearout alerts,
which poll the Proxmox API directly. Users excluding disks (e.g.
--disk-exclude sda) still received alerts for those disks.
Agent now sends its DiskExclude patterns in each report. The server
stores them on the Host model and consults them during Proxmox disk
polling — excluded disks get a synthetic healthy status passed to
CheckDiskHealth so any existing alerts clear immediately.
Also adds FreeBSD pseudo-filesystem types (fdescfs, devfs, linprocfs,
linsysfs) to the virtual FS filter and /var/run/ to special mount
prefixes, fixing false disk-full alerts on FreeBSD for fdescfs mounts.
Relax the Linux-only gate on SMART collection to also run on FreeBSD.
Add FreeBSD disk discovery via sysctl kern.disks (lsblk is Linux-only).
The smartctl invocation and JSON parsing are already platform-agnostic.
Expand the smartctl collector to capture detailed SMART attributes (SATA
and NVMe), propagate them through the full data pipeline, persist them
as time-series metrics, and display them in an interactive disk detail
drawer with historical sparkline charts.
Backend: add SMARTAttributes struct, writeSMARTMetrics for persistent
storage, "disk" resource type in metrics API with live fallback.
Frontend: enhanced DiskList with Power-On column and SMART warnings,
new DiskDetail drawer matching NodeDrawer styling patterns, generic
HistoryChart metric support with proper tooltip formatting.
Implements server-side persistence for AI chat sessions, allowing users
to continue conversations across devices and browser sessions. Related
to #1059.
Backend:
- Add chat session CRUD API endpoints (GET/PUT/DELETE)
- Add persistence layer with per-user session storage
- Support session cleanup for old sessions (90 days)
- Multi-user support via auth context
Frontend:
- Rewrite aiChat store with server sync (debounced)
- Add session management UI (new conversation, switch, delete)
- Local storage as fallback/cache
- Initialize sync on app startup when AI is enabled
When a user's reverse proxy redirects HTTP to HTTPS, Go's default HTTP
client behavior converts POST requests to GET on 301/302 redirects
(per HTTP specification). This causes the Pulse server to return 405
"Only POST is allowed" errors.
Added CheckRedirect to all agent HTTP clients (host, docker, kubernetes)
that returns a clear error message guiding users to use the correct
protocol in their --url flag instead of silently following redirects.

Previously, the PULSE_DISK_EXCLUDE environment variable and --disk-exclude
flag only filtered mount points in the hostmetrics collector. This change
extends the exclusion to SMART data collection.
Changes:
- Updated smartctl.CollectLocal() to accept diskExclude patterns
- Added matchesDeviceExclude() for block device pattern matching
- Patterns support: exact match (sda), prefix (nvme*), contains (*cache*)
- Updated hostagent to pass DiskExclude to SMART collector
- Added comprehensive tests for pattern matching
- Updated documentation
Allows specifying which IP address the agent should report, useful for:
- Multi-homed systems with separate management networks
- Systems with private monitoring interfaces
- VPN/overlay network scenarios
Usage:
pulse-agent --report-ip 192.168.1.100
PULSE_REPORT_IP=192.168.1.100 pulse-agent
Ubuntu was showing as "debian 24.04" because we used PlatformFamily
(which is "debian" for all Debian derivatives) instead of Platform
(which is "ubuntu" for Ubuntu).
Now uses Platform first, falling back to PlatformFamily only if empty.

When PBS is installed directly on a PVE host (an officially supported
configuration), the agent now detects and registers BOTH products instead
of only detecting PVE.
Changes:
- Add detectProxmoxTypes() to detect all Proxmox products on a host
- Add RunAll() method to register each detected product separately
- Use per-type state files (proxmox-pve-registered, proxmox-pbs-registered)
to track registration status for each product independently
- Maintain backward compatibility with legacy single state file
- Add tests for new state file path logic
- Add power.go with Intel RAPL and AMD energy driver support
- Read CPU package, core, and DRAM power consumption in watts
- Sample energy counters over 100ms interval to calculate power
- Add PowerWatts field to Sensors struct for API reporting
- Integrate power collection into host agent sensor gathering
- Add comprehensive tests for power collection module
Supports Intel CPUs (Sandy Bridge+) via RAPL and AMD Ryzen/EPYC
via the amd_energy kernel module.
Closescommunity-scripts/ProxmoxVE#9575
Extended lm-sensors parsing to capture all sensor readings:
- Fan speeds (RPM) from SuperIO chips like NCT6687
- Additional temperatures (DDR5/RAM, motherboard, etc.)
- All sensors not already captured as CPU/NVMe/GPU
Updated frontend tooltip to display fans and additional sensors
in separate sections with formatted names.
Closes discussion #911
Users can now exclude specific mount points from disk monitoring:
- Via CLI: --disk-exclude /mnt/backup --disk-exclude '/media/*'
- Via env: PULSE_DISK_EXCLUDE=/mnt/backup,*pbs*
Patterns support:
- Exact paths: /mnt/backup
- Prefix patterns: /mnt/ext*
- Contains patterns: *pbs*
This addresses the common case where external disks or
PBS datastores are being monitored but shouldn't be.
- Add smartctl package to collect disk temperature and health data
- Add SMART field to agent Sensors struct
- Host agent now runs smartctl to collect disk temps when available
- Backend processes agent SMART data for temperature display
- Graceful fallback when smartctl not installed
When the server disables command execution for an agent, we now properly
call Close() on the command client to tear down the WebSocket connection.
Previously we just set the pointer to nil which left the goroutine running
with an orphaned connection.
This implements full remote configuration for the AI command execution setting:
Backend:
- Add CommandsEnabled field to HostMetadata for persistent storage
- Add GetHostAgentConfig/UpdateHostAgentConfig methods to Monitor
- Add /api/agents/host/{id}/config endpoint (GET for agents, PATCH for UI)
- Server includes config in report response for immediate agent application
- Agent parses response and dynamically enables/disables command client
Frontend:
- Add 'AI Commands' toggle column in Managed Agents table
- Toggle immediately updates server config; agent applies on next heartbeat
- Add 'Enable AI command execution' checkbox in agent installer wizard
- Checkbox adds --enable-commands flag to generated install commands
This allows users to:
1. Enable at install time via checkbox in the wizard
2. Toggle remotely via the Managed Agents UI for existing agents
3. Agents apply changes automatically on their next report cycle
- Add CommandsEnabled field to AgentInfo in pkg/agents/host/report.go
- Agent now reports whether AI command execution is enabled
- Server stores and exposes this via Host model
- Frontend can now show which agents have commands enabled
- This provides visibility before implementing remote configuration
BREAKING CHANGE: AI command execution on agents is now disabled by default.
Users who want AI auto-fix must explicitly enable it with --enable-commands
flag or PULSE_ENABLE_COMMANDS=true environment variable.
Changes:
- Add --enable-commands flag (opt-in for command execution)
- Commands disabled by default for security (defense-in-depth)
- --disable-commands is now deprecated (logs warning, no longer needed)
- PULSE_DISABLE_COMMANDS deprecated in favor of PULSE_ENABLE_COMMANDS
- Update installer script to use --enable-commands
- Backwards compatibility: PULSE_DISABLE_COMMANDS=false still enables commands
This addresses community feedback about secure defaults for arbitrary
command execution on production infrastructure.

PROBLEM:
When two Proxmox hosts have the same hostname (e.g., 'px1' on different networks),
the auto-registration was matching by name and overwriting the first with the second.
This has been a recurring issue (#104) with at least 3 prior fix attempts.
ROOT CAUSE:
The auto-register handler matched existing nodes by BOTH Host URL and Name.
Matching by name is incorrect - different physical hosts can share hostnames.
FIXES:
1. Remove name-based matching in auto-registration - match by Host URL only
2. Add disambiguateNodeName() to append IP when duplicate hostnames exist
3. Add regression tests to prevent this from breaking again
Now when registering two hosts named 'px1':
- First becomes: px1
- Second becomes: px1 (10.0.2.224)
Both are stored as separate nodes with their own credentials.
LXC containers share the host's /sys/class/dmi/id/product_uuid, which
causes gopsutil to return identical HostIDs for all LXC containers on
the same physical host. This results in agent ID collisions where
multiple LXC containers appear as a single host in Pulse.
The fix detects LXC containers and prefers /etc/machine-id (which is
unique per container) over gopsutil's HostID.

The isLoopback function in internal/hostagent/agent.go was unused in
production code - it was a duplicate of the same function in
internal/hostmetrics/collector.go which is actively used.
Removed the dead code along with its associated tests to reduce
maintenance burden and improve code clarity.
Issues found during scenario testing:
1. Version propagation: The hostagent and dockeragent packages were
reporting their own Version (0.1.0-dev) instead of the unified
agent's version. Added AgentVersion config field to pass the
parent's version down.
2. macOS legacy cleanup: The install.sh script was missing cleanup
for pulse-docker-agent on macOS.
3. Windows legacy cleanup: The install.ps1 script was missing cleanup
for legacy PulseHostAgent and PulseDockerAgent services.
These fixes ensure:
- Unified agent reports consistent version across host/docker metrics
- Legacy agents are properly removed on all platforms during upgrade
- Users migrating from legacy agents get a clean transition
Add seamless migration path from legacy agents to unified agent:
- Add AgentType field to report payloads (unified vs legacy detection)
- Update server to detect legacy agents by type instead of version
- Add UI banner showing upgrade command when legacy agents are detected
- Add deprecation notice to install-host-agent.ps1
- Create install-docker-agent.sh stub that redirects to unified installer
Legacy agents (pulse-host-agent, pulse-docker-agent) now show a "Legacy"
badge in the UI with a one-click copy command to upgrade to the unified
agent.
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.

The temperature collection in pulse-host-agent was broken on all Linux
distributions due to an incorrect platform check.
Root cause:
- collectTemperatures() checked `if a.platform != "linux"` at agent.go:316
- normalisePlatform() returns the raw distro name from gopsutil (debian, ubuntu, pve)
- This caused temperature collection to be skipped on ALL Linux hosts
Fix:
- Changed check to `if runtime.GOOS != "linux"` which correctly identifies Linux
- runtime.GOOS returns "linux" regardless of distribution
Also fixed documentation typo:
- Changed "Servers tab" to "Hosts tab" in HOST_AGENT.md and TEMPERATURE_MONITORING.md
- Reported by user in issue #661 comments
Testing:
- Verified build succeeds
- Confirmed runtime.GOOS returns "linux" on Linux systems

Implements temperature monitoring in pulse-host-agent to support Docker-in-VM
deployments where the sensor proxy socket cannot cross VM boundaries.
Changes:
- Create internal/sensors package with local collection and parsing
- Add temperature collection to host agent (Linux only, best-effort)
- Support CPU package/core, NVMe, and GPU temperature sensors
- Update TEMPERATURE_MONITORING.md with Docker-in-VM setup instructions
- Update HOST_AGENT.md to document temperature feature
The host agent now automatically collects temperature data on Linux systems
with lm-sensors installed. This provides an alternative path for temperature
monitoring when running Pulse in a VM, avoiding the unix socket limitation.
Temperature collection is best-effort and fails gracefully if lm-sensors is
not available, ensuring other metrics continue to be reported.

- 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.
Introduces granular permission scopes for API tokens (docker:report, docker:manage, host-agent:report, monitoring:read/write, settings:read/write) allowing tokens to be restricted to minimum required access. Legacy tokens default to full access until scopes are explicitly configured.
Adds standalone host agent for monitoring Linux, macOS, and Windows servers outside Proxmox/Docker estates. New Servers workspace in UI displays uptime, OS metadata, and capacity metrics from enrolled agents.
Includes comprehensive token management UI overhaul with scope presets, inline editing, and visual scope indicators.
