**Stacked on #2675** (TrueNAS disk temperature alerts by disk type). Merge that first; this branch contains its commit. ## Problem A Proxmox physical disk that only the node's own sensors report never raised a temperature alert: - `CheckDiskHealth` judges health and wearout only; - unified evaluation types TrueNAS physical disks, not PVE ones. So Physical Disks could read a disk **Running Hot** under the per-type thresholds while alerts stayed silent. Whether a disk alerted depended on whether a Pulse agent ran on the node: agent-covered disks alert through `CheckHost` at the same thresholds. #1347 shows users look for disk temperature thresholds in the Proxmox tabs. ## Change - **`CheckProxmoxDiskTemperature`** (`internal/alerts/proxmox_disk_temperature.go`) raises a `diskTemperature` metric alert under the disk's existing PVE alert reference. It is judged by the disk temperature policy: the disk type's `DiskTempByType` entry under the agent Disk Temp default, which switches it off for every type. The alert carries the disk's serial, WWN and `diskType`, like the health and wearout alerts. - **One alert per disk.** `mergeHostAgentSMARTIntoDisks` marks a disk that a still-reporting linked agent lists in its SMART report (`AgentSMARTReported`, internal, never serialized). That disk is the agent's: `CheckHost` alerts on it, and an open PVE alert closes with `moved_to_agent`. A lapsed agent owns nothing, so the node's own current readings keep alerting while its agent is silent. - **Holds and clears.** Only a reading collected this poll is judged (`diskinventory.TemperatureCollected`), so a retained value holds the alert. An excluded device, or a switched-off policy, closes it. - **Stability.** A new `proxmox-disk` alert delay defaults to 5s, so warnings wait the same 300s noisy-gauge window as agent and TrueNAS disk temperatures. Critical readings bypass it. - **Config save.** `reevaluateActiveAlertsLocked` re-judges the alert per disk type. Without this it would fall through to guest thresholds, which have no disk temperature, and resolve on every save. An alert without a recorded type uses the lowest per-type trigger. - **History.** `ProxmoxPhysicalDiskAlertIdentifiers` lists the new `<ref>::metric-threshold:diskTemperature` identifier, so resource history owns its rows by recorded hardware identity, as #2646 does for health and wearout. - **Copy.** The Agents "Disk temperature by type" card says it covers agent, TrueNAS and Proxmox disks. ## Evidence Private mock stack (8 PVE nodes) with a local-only overlay pinning PVE disk readings: | Disk | Physical Disks | Alert | |---|---|---| | pve1 NVMe 63°C | Healthy | none | | pve2 SATA 56°C | Running Hot | warning, trigger 55, after the 300s window | | pve3 NVMe 72°C | Running Hot | warning, trigger 70, after the 300s window | | pve3 SAS 63°C | Healthy | none | | pve3 SATA 66°C | Running Hot | critical at once | The alert card reads: "Samsung 870 EVO 1TB (/dev/nvme2) · Temperature · Temperature 66°C, above the 55°C alert level · Clears once it drops to 50°C or lower and stays there for 5 minutes." ## Tests - `internal/alerts/alerts_test.go`: - the policy (per type, raised trigger); - ownership with `moved_to_agent`, the hold without a reading, exclusion, the off switch; - the stability window; - re-judging on save, including the lowest-trigger hold; - history identifiers. - `internal/monitoring/physical_disk_roundtrip_test.go`: the marker for reporting agents only (not a lapsed one), the SMART fallback path, and that `checkPhysicalDiskAlerts` passes collected readings, ownership and exclusion. - `internal/unifiedresources/store_test.go`: a temperature alert row is owned by its disk and still found by a read by its reference. - `internal/models/deepcopy_test.go`: the marker survives cloning and stays out of JSON. - `ThresholdsTable.test.tsx`: the card copy. - Ten wiring points were mutation-checked (marker, lease condition, collected reading, ownership, exclusion, re-judge branch, lowest trigger, resolution, history identifier); each removal fails a test. ## Second opinion - Fixed: an offline agent's retained SMART rows kept ownership, so neither side alerted while the agent was silent. Ownership now needs a reporting lease. - Kept, documented in `alerts.md`: on the first poll after an agent is newly linked to a disk with an open PVE alert, both alerts can be open until the next disk poll. This is the same window as the node-to-agent usage alert handover. ## Not in this PR - Like the health and wearout alerts, a disk that leaves the inventory keeps its temperature alert until the 24-hour stale sweep. - Per-host Disk Temp overrides do not reach PVE-only disks, which have no agent host.
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.
