On Physical Disks, a SMART-passed disk with good life running at 72°C
read **Replace Now** ("Disk temperature is 72C"), and **Replace** on
phones. Disk risk grades temperature (`temperature_high`, ≥70°C
critical, ≥60°C warning), and the Health verdict mapped any critical
risk to Replace Now. That tells a homelab user to buy a disk when the
fix is airflow. Alerts already keep heat separate: the SMART health and
wearout alerts skip `temperature_high`, and disk heat is raised as a
Temperature metric.
## Change
- `diskPresentation.ts` keeps each risk reason's code and severity, and
splits the reasons into heat and everything else.
- FAILED health, any other critical reason, or a critical level that no
reason explains → **Replace Now** (unchanged).
- Heat alone → **Running Hot** (phone **Hot**). Red at the critical
tier, amber at warning. The temperature reason is still the cell title
and the drawer summary.
- Other warning evidence, SMART counters or low life → **Needs
Attention** (unchanged).
- The more severe class names the verdict, and failure evidence wins a
tie. Merged risks that list heat first (`mergePhysicalDiskRisk` does not
re-sort) no longer hide pending sectors behind a temperature summary.
- Sort priority and the health filter derive from the same verdict.
Order is Replace Now, then red Running Hot, then Needs Attention, then
amber Running Hot. Hot disks stay in **Needs attention** and land in
Critical or Warning by their tier.
- Data with no reason codes keeps the old behaviour.
## Not changed
Thresholds. The tier still comes from the server's flat 60/70°C rule,
not the per-type alert thresholds that colour the Temp cell. An NVMe at
60–64°C therefore reads amber Running Hot next to a green Temp cell.
That disk read Needs Attention before this change, so the judgment is
the same and only the word is clearer. Reconciling the thresholds is
being done separately.
## Verification
- New tests in `diskPresentation.test.ts` cover heat at both tiers,
failure evidence listed after heat, heat plus wear, an unexplained
critical level, sort order and the health filter. Five of them fail on
the old code, including the sort test, whose device names make name
order alone disagree. `DiskList.test.tsx` checks the full and compact
words, tone, title and row order.
- Targeted suites (storageBackups, Storage, GuestPhysicalDisks,
frontendResourceTypeBoundaries): 89 files, 1513 tests pass. tsc and
eslint are clean, and the canonical platform audit is clean.
- Browser check on a private mock stack (local, uncommitted generator
overlay pinning pve3 disks at 72°C, 63°C, and 72°C with 2 pending
sectors), at 1440×900 and 390×844. The rows read Replace Now / Running
Hot / Needs Attention / Running Hot (phone: Replace / Hot / Attention /
Hot) with the expected tones and titles. The drawer reads "Running Hot ·
Disk temperature is 72C". The `status=attention|critical|warning`
filters list the expected rows. A same-session control with the old file
showed the 72°C disk as Replace Now. The receipt is
`frontend-modern/browser-verification/259ae9ced29e073f.json`.
Pulse
Real-time Proxmox, Docker and Kubernetes monitoring that finds what needs attention.
Pulse is a self-hosted monitoring workspace for Proxmox, Docker, Kubernetes, TrueNAS, physical and virtual machines, and early-access VMware vSphere environments. It combines live infrastructure state, history, alerts, recovery visibility, and scheduled health checks without requiring a conventional enterprise monitoring stack.
Why Pulse
- It watches between visits. Alerts and Pulse Patrol find failed backups, capacity pressure, restart loops, unhealthy containers, clock drift, and other problems that dashboards cannot surface when nobody is looking.
- It keeps each platform familiar. Proxmox, Docker, Kubernetes, TrueNAS, vSphere, and machines have dedicated views, backed by one shared resource model for search, alerts, history, and investigation.
- It stays operator-controlled. Credentials are encrypted at rest, API tokens are scoped, agent commands are disabled by default, and governed fixes require the configured policy and approval path.
Platform coverage
| Platform | Coverage |
|---|---|
| Proxmox VE, PBS, and PMG | Nodes, guests, storage, backups, replication, Ceph, mail gateways, and alerts |
| Docker and Podman | Hosts, containers, Compose projects, Swarm services, health, images, and updates |
| Kubernetes | Clusters, nodes, workloads, pods, services, storage, and events through the unified agent |
| TrueNAS SCALE and CORE | Pools, datasets, disks, snapshots, replication tasks, apps, VMs, and alerts |
| Linux, Windows, and macOS machines | Host health, filesystems, networking, temperatures, RAID, and availability through the unified agent |
| VMware vSphere | Early-access inventory, hosts, clusters, VMs, datastores, networks, snapshots, and recovery context; validate against your own vCenter before production use |
Platform pages keep storage and recovery information beside the infrastructure it belongs to. Alerts, Actions, and Patrol remain cross-platform views.
Patrol: monitoring that does rounds
Pulse Patrol runs scheduled checks across the current state and recent history of your infrastructure. Community installations can use a local model or their own AI provider for watch-only analysis. Pulse Pro adds investigation and policy-bound fixes with approval, verification, and an audit trail.
Pulse also includes an interactive Assistant and an MCP adapter for external clients such as Claude Code and OpenCode. Both sit on top of the same scoped inventory, metrics, alert, storage, and governed-action contracts.
Quick start
Choose an exact version from the latest release and keep that version pinned during installation.
Docker
docker run -d \
--name pulse \
-p 7655:7655 \
-v pulse_data:/data \
-e PULSE_DEPLOYMENT_METHOD=docker_run \
--restart unless-stopped \
rcourtman/pulse:vX.Y.Z
Open http://<your-ip>:7655 and follow the bootstrap-token setup. Docker host
monitoring is provided by the unified agent; the Pulse server container does
not need the Docker socket.
Proxmox LXC, Linux, and Kubernetes
The installer is signed. Verify install.sh against the pinned
pulse-installer key before running it:
export PULSE_VERSION=vX.Y.Z
curl -fsSLO "https://github.com/rcourtman/Pulse/releases/download/${PULSE_VERSION}/install.sh" &&
curl -fsSLO "https://github.com/rcourtman/Pulse/releases/download/${PULSE_VERSION}/install.sh.sshsig" &&
ssh-keygen -Y verify \
-f <(printf '%s\n' 'pulse-installer namespaces="pulse-install" ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIMZd/DaH+BldzOkq1A8KVTcFk73nAyrE8aJOyf7i00jm pulse-installer') \
-I pulse-installer \
-n pulse-install \
-s install.sh.sshsig < install.sh &&
bash install.sh --version "${PULSE_VERSION}"
Paste the whole block: installation stops if either download or signature verification fails. Do not run the final command separately to bypass a failure.
The GitHub installer installs the Pulse server. Install and upgrade agents (including v5-to-v6 agent upgrades) with the per-host command generated under Settings → Infrastructure → Install on a host.
Do you need an agent?
Often not. Proxmox VE, PBS, and PMG are monitored through the Proxmox API with a read-only token, so nothing runs on the host and the generated setup script creates a privilege-separated monitoring user. Install the unified agent only where you want data the platform API cannot provide, such as host SMART health, temperatures, Docker hosts, or standalone machines.
The agent is operator-controlled by design. Command execution is off by
default, the local listener binds to localhost, and generated systemd units
ship hardened. On Linux, the installer's --least-privilege profile runs the
service as a dedicated non-root user, with optional scoped sudo grants for
the few collectors that need elevation. The
agent security model documents exactly what the
agent can and cannot do at each privilege level.
Important
GitHub release assets and
rcourtman/pulseimages are Community builds. Relay, Pro, and eligible legacy customers should use the private image or Linux archive provided by the Pulse download portal. Replacing a private Pro runtime with a public Community build removes its private runtime hooks.
Editions
- Community — self-hosted monitoring, seven days of metric history, core SSO, update alerts, and Patrol with your own provider or local model.
- Pro — Community plus Patrol investigation, governed fixes, ninety days of history, centralized agent profiles, RBAC, audit logging, and reporting.
- MSP — for managed service providers: one Pulse Account running many client workspaces, each with an isolated Pulse runtime — separate dashboards, alerts, users, audit history, and reports. Free sixty-day two-client evaluation at Pulse for MSPs.
Relay is no longer sold. Existing Relay subscribers receive Pro features at their current price for as long as their subscription continues. Existing paired phones keep working until 31 March 2027. Relay connects the app, not the web UI. Use your own VPN or tunnel for remote web access. For phone alerts, add an ntfy, Gotify or Pushover destination and open Pulse in your phone's browser.
Core self-hosted monitoring is not gated by monitored-system or child-resource volume. See the runtime-aligned capability reference and current plans for details.
