The unified agent's Linux installer only offered the root profile, and the
docs called non-root unsupported. That default is the most-cited reason
security-conscious evaluators reject Pulse without trying it. install.sh
gains --least-privilege: the service runs as a dedicated nologin
pulse-agent system user with every existing hardening directive, no
LXC-attach ambient capabilities, docker-group membership for socket reads,
and refusal (not silent root fallback) on appliance platforms, non-systemd
init systems, and --enable-commands. Optional --grant-smart and --grant-pct
restore the only two collectors that need elevation through
visudo-validated exact-command sudoers rules and root-owned wrappers the
agent reaches via new absolute-path-only PULSE_SMARTCTL_PATH /
PULSE_PCT_PATH overrides; the pct grant covers pct list and pct df only
and can never widen into pct exec. --update preserves the profile and its
grants by reading the installed unit.
The agent now authors a privilege block in its report (effective root,
service user, active helpers), carried through models into the fleet
doctor as a descriptive field: Agent Doctor shows the profile and its
helpers instead of presenting intentionally absent collectors as a fault,
and a least-privilege agent can never be marked unhealthy on that evidence
alone.
The unified agent gains an availability module: probe assignments
arrive through the signed remote-config channel (missing key clears
the schedule), each enabled target runs on its own clamped interval
through the shared probe core, and results queue in a bounded
drop-oldest buffer. A result is offered to the primary server until
one delivery succeeds and never again after - buffered offline
reports are stripped of availability results so the disk buffer
cannot replay observations the queue still holds. ApplyHostReport
feeds accepted reports into the probe ingestion path, where the
ownership check and failure accounting live, and the probe agent id
is projected onto unified availability resources for source
attribution in the UI.

f62f35e24 restored the v5 used | cache | free memory split for Proxmox
nodes and guests, but standalone host agents still reported a flat
used/free pair, so the Machines page memory bar could not show the
reclaimable segment. Flagged by the Machines page v5 parity audit.
- Host agent reports cacheBytes (gopsutil Available minus Free); the
ZFS ARC adjustment recomputes free so used + cache + free still
covers the total.
- ApplyHostReport maps the field into models.Memory.Cache and clamps
inconsistent or older-agent reports so used + cache never exceeds
total.
- AgentMemoryMeta carries cache onto unified resources so the frontend
agent payload exposes it.
- Mock generic hosts split a third of non-used pages as cache, and the
node-linked host conversion now holds the invariant instead of
stacking the node's cache on top of a recomputed free.
- Contracts: monitoring, unified-resources, and storage-recovery now
document the split (also covering the f62f35e24 node/guest surface,
which landed without contract deltas).
On a Proxmox node, physical disks collected by the host agent were keyed by
the NVMe controller (e.g. "nvme0 [nvme]") instead of the namespace, reported
sizeBytes 0 (or a stale filesystem-usage value), and flickered as the agent
reading intermittently replaced the authoritative Proxmox disks/list reading.
Root causes:
- smartctl --scan-open reports NVMe disks by their controller char device
(/dev/nvme0), and that scan label became the reported devPath.
- DiskSMART carried no capacity, so the server backfilled size by matching the
SMART device against host filesystem-usage entries, which never match a whole
partitioned/LVM/ZFS disk, leaving size 0.
- The unified-resource merge let the agent's controller label overwrite the
canonical Proxmox /dev/... devPath.
Fixes:
- The agent now reports the canonical block device (an NVMe controller resolves
to its namespace) and the authoritative capacity from /sys/block, with the
smartctl user_capacity / nvme_total_capacity as a cross-platform fallback.
Disks behind multiplexing controllers (megaraid, cciss, areca) keep their
disambiguating label and smartctl-reported size.
- SizeBytes flows through the agent report, host model, and adapter; the
filesystem-usage match is demoted to a legacy fallback.
- The merge keeps a canonical /dev/<device> devPath and never downgrades it to
a scan label, so an un-updated agent can no longer corrupt Proxmox data.

Parse the /proc/mdstat operation keyword for mdadm arrays and propagate it through host reports, models, unified resources, monitoring views, alert metadata, and AI storage summaries.
Treat recovery and reshape as rebuild signals while silencing routine check and resync maintenance, with fallback rebuild detection only when no mdstat operation is available.
Tests cover mdstat operation parsing plus recovery, check, and resync alert behavior.
Fixes#1446
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.
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.

- 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

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.

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.
