A host agent that stops reporting keeps its last SMART rows in state.
The Proxmox physical-disk merge copied that agent's temperature and I/O
counters into the disk together with its "available" collection state,
the registry merged the agent's retained rows into the canonical disk the
same way, and every full disk poll wrote the frozen temperature to SMART
history as a new sample. A dead agent's disk temperatures therefore stayed
"collected" in the API and kept extending the history chart indefinitely.
Expiring the agent's reporting lease is now the point where those
readings stop being current. ExpireHostTelemetry keeps the SMART
temperature and I/O values as last-known evidence but marks them
unavailable ("host agent stopped reporting"), as the physical-disk
contract asks for retained evidence. Because MergeStatus lets any
available state win, a Proxmox disk row still holding the earlier copy
would mask that, both on skipped disk polls and when the PVE host is down
and never disk-polled again. diskinventory.MergeReportedStatus lets a
source's later word on its own field supersede the availability it
supplied earlier; the monitoring merge and both registry ingest orders
use it. Every SMART temperature history writer now records a
temperature only when its current state is collected, so a retained
reading (an agent past its lease, or a disk in standby) is not written as
a new sample.
Agents before 6.2 send no collection provenance, so their merged
temperature is recorded as collected from "host_agent" instead of
inheriting Proxmox's "unsupported", keeping their history intact.
Expiry is now compare-and-set on the report time the evaluation judged
stale, so a report accepted in between is not expired.
SMART attributes, wearout and health stay last-known on purpose: they
are durable health evidence, and dropping them would resolve disk-health
and low-life alerts when an agent goes quiet. Disk temperature alerts
are evaluated from the agent's own report, so they never read this
merged value. The node-temperature path (agent sensors feeding
node.Temperature.SMART, which the disk merge labels proxmox_node_smart)
is gated by the agent's sighting in #2582; a carried node reading can
still stamp a disk as collected and belongs to that path.
Pulse documentation
Start here for installation, platform setup, security, operations, and Pulse Intelligence. Commands, configuration keys, image names, API fields, and product identifiers remain untranslated in localized guides.
Start here
- Install Pulse — signed Proxmox/Linux installation, Docker, Docker Compose, Kubernetes, and first-run setup.
- Production deployment and security — least-privilege Proxmox setup, root-agent boundaries, discovery, supply-chain verification, plan limits, scale evidence, and a rollout checklist.
- Upgrade from Pulse v5 — migration prerequisites, rollback, agent continuity, and post-upgrade checks.
- Releases and update channels: choosing Stable or Preview, beta and RC expectations, and how releases are tested and promoted.
- Configure Pulse — authentication, notifications, discovery, retention, and system settings.
- Deployment models — data locations, lifecycle, and differences between supported deployment paths.
- Troubleshooting and FAQ — common failures, diagnostics, and operator questions.

Platforms and agents
- Proxmox Backup Server
- Proxmox Mail Gateway
- Docker and Podman
- Kubernetes and Helm
- TrueNAS SCALE and CORE
- Unified Agent
- Agent security
- VM disk monitoring
- ZFS monitoring
- Temperature monitoring
VMware vSphere support is early access. Current builds expose dedicated vSphere inventory and recovery context, but operators should validate the integration against their own vCenter before production use.
Monitoring and operations
- Metrics history
- Recovery data
- Webhooks
- Automatic updates
- Centralized agent management (Pro)
- Operational trust model
- Current product screenshots
Pulse Intelligence
- Assistant, Patrol, and external-agent overview
- Patrol modes and safety
- Assistant safety model
- External agent HTTP and MCP substrate
Patrol watch-only analysis is available on Community with a local model or the operator's own provider. Investigation and governed fixes require the relevant Pulse Pro capabilities.
Security, privacy, and access
- Production deployment and security
- Security review scope
- Authentication and credential storage review packet
- Security guide
- Privacy and telemetry disclosure
- OIDC and SSO
- Proxy authentication
- Role-based access control (Pro)
- Audit logging (Pro)
- Reverse proxy configuration
- Code-signing policy
Plans and managed access
- Community, Relay, and Pro capabilities
- Relay and Pulse Mobile handoff
- Multi-tenant organizations (Enterprise/custom)
- Provider-hosted MSP operations (request-assisted)
Pulse Cloud is not generally available. Ordinary self-hosted Pulse remains the primary installation path; MSP and Enterprise access are explicit commercial paths rather than defaults in self-hosted setup.
Development and reference
Detailed design notes and dated migration specifications may remain in this directory for maintainers, but they are not operator setup guides unless they are linked from the sections above.
Previous versions and migrations
- Upgrade from v4 to v5
- Retired unified-navigation migration — historical context only; current Pulse uses platform-shaped navigation.
- Move a Pulse installation
