## Problem A physical disk behind a RAID controller (target such as `megaraid,3`) with no usable serial or WWN had its SMART history written under one key and read under another, so its temperature and SMART charts stayed empty. - Host agent: writes under `HostSMARTDiskMetricID`, e.g. `host-pve:sdd@ctrl0/megaraid,3`. - Proxmox: writes under `PhysicalDiskMetricID`, which returns `ProxmoxPhysicalDiskSourceID`, e.g. `pve-node1--dev-sdx:sdx@/megaraid,0`. - Reader: `BuildMetricsTarget` passed those source IDs, which already name the member, to `PhysicalDiskMetaMetricID`. That function appended the topology again: `host-pve:sdd@ctrl0/megaraid,3:sdd@ctrl0/megaraid,3`. The same happened in a registry rehydrated from persisted resources. ## Fix `PhysicalDiskMetaMetricID` now follows the Proxmox writer. A fallback that already ends in the member's topology is returned unchanged. The topology is appended only to a fallback without it: - a Proxmox source ID from before members were scoped, which `PhysicalDiskMetricID` scopes the same way; - the canonical resource ID that `PhysicalDiskView.MetricResourceID` falls back to. TrueNAS disks carry no controller target and are unaffected. ## Existing history - **SMART:** no SMART writer used the doubled key, so samples already stored become readable without a migration. - **Disk I/O:** a linked node's agent with no SMART reading for a member, such as a standby row, files the device's I/O under the Proxmox disk's metrics target. That target was the doubled key. The I/O now lands beside the member's SMART history. Samples already stored under the doubled key are left to age out: nothing reads them, and they are the block path's counter filed under its one merged member. - Mock seeding keys these disks by `disk.ID`, the single-scoped key, so it already matched. ## Proof - `TestIdentitylessControllerMembersReadTheirWritersHistory` (`internal/monitoring/issue1595_collection_trust_test.go`) drives the real writers: `writeHostSMARTMetrics`, `writeHostPhysicalDiskIOMetrics` and the Proxmox `writeSMARTMetrics`. It then queries the store at `MetricsTarget` for five members in a live registry and in one rehydrated through a JSON round trip. The members are two agent members sharing a path, a lone agent member with I/O, a Proxmox member, and a standby member merged into its linked node's Proxmox row. Before the fix all ten targets read the doubled key. - `TestPhysicalDiskMetaMetricIDScopesAControllerMemberOnce` (`internal/unifiedresources/canonical_ids_types_test.go`) pins each fallback shape against its writer: agent, smartctl-labelled agent, Proxmox, legacy Proxmox, canonical resource ID, and a disk that is no controller member. Before the fix, three cases failed with the doubled key. ## Stacking This branch sits on #2685, which sits on #2679, because both edit `physical_disk_ids.go` and the proof file. It supersedes #2661, which carried the same reader fix but conflicted with this stack and with main.
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.
