#2636 made the alert disk temperature policy the only judge of disk heat, but it resolved that policy by disk type alone. Disk temperature alerts (`CheckHost`) evaluate each SMART disk under the thresholds of the host agent that reports it. An explicit Disk Temp override on that host, or one inherited from its linked node or guest, replaces the per-type trigger, and a host whose alerts are switched off raises nothing. So a host with an 80C Disk Temp override still read **Running Hot** on Physical Disks at the 70C NVMe trigger. Patrol flagged it too, and a host with alerts switched off still read hot. The Alerts thresholds page promises the opposite: "Setting a Disk Temp override on a host above replaces these for all of that host's disks". ## What changes - **Backend policy:** `alerts.Manager.HostDiskTemperatureThreshold(host, diskType)` resolves the policy for a host the way `CheckHost` does, from the same helpers (`resolveHostThresholdsNoLock`, `hostThresholdOverrideNoLock`, `hostDiskTemperatureThresholdNoLock`). A disabled override gives no threshold. `DiskTemperatureThreshold(diskType)` is now its hostless case. - **Patrol and the AI chat context:** `ThresholdProvider.GetDiskTemperatureThreshold(host, diskType)`. Each unified physical disk finds its host by walking its parent to the agent machine, through the pool for Unraid array and cache disks. - **Physical Disks, the disk detail, the pool drawer's linked disks and the guest drawer** pass the reporting machine's override keys to `resolveDiskTemperatureDisplayThresholds`. Keys follow `CheckHost`'s order: agent ID, canonical resource ID, then the merged node or guest. The resolver returns null (uncoloured, never hot) for an override or agent default that switches the host's alerts off. The browser rebuilds `CheckHost`'s key chain from what it loads, so a few identity edge cases can still differ from alerts and Patrol (listed in `storage-recovery.md`): on the Storage page, a disk whose agent an operator manually linked into a VM; an override inherited through agent link hints the API does not publish (an unmerged linked node or guest), or stored under a linked node's own canonical ID; and guest keys in the guest drawer for an agent merged into a guest it is not automatically linked to. Overrides set on the agent's own row, or on the node or guest it is merged with, reach every surface. ## Verification - `TestHostDiskTemperatureThresholdMatchesCheckHostOverrides` checks each case against what `CheckHost` actually fires: no override, host override, host override without Disk Temp, an override under the canonical resource the agent ID resolves to, linked-node and linked-guest overrides, a host override shadowing a node one, a switched-off Disk Temp, and a disabled host, linked node or linked guest. - `TestPatrolJudgesAgentDisksByTheAgentDiskTemperatureOverride` uses a real registry with two agents, one overridden. A mutation that drops the owner lookup fails it. - Frontend tests cover the resolver, the owner walk and key order, DiskList with three hosts, the presentation map, pool-drawer linked disks and the guest drawer. - Private mock stack: three NVMe disks pinned at 72C. Before (main frontend): all three read Running Hot. After: - pve1, with an 80C override, reads Healthy (green). - pve2 still reads Running Hot. - pve3, with alerts off, is uncoloured. - Moving pve2's override onto its linked node ID turns it Healthy. - Checked at 1440 and 375 with no overflow. The receipt is in `frontend-modern/browser-verification/`. - A read-only second-opinion review ran twice. Round 1's findings (frontend key order, guest drawer canonical ID, disabled agent default, doc wording) are fixed in the first commit. Round 2's are the parity cases and the documented browser limits in the second commit.
Pulse
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.
