Stacked on #2715 (its commit is the parent of this one); either can land first. ## Problem `mergeInto` passed nil thresholds to `mergeMetrics`, so every source merge into an existing row (snapshot and record ingest alike) judged metric freshness by the registry defaults, while the stale pass and manual links used the monitor's configured thresholds. Two visible results: - A Proxmox node polled every two minutes (four-minute threshold) merged with its auto-linked agent showed the silent agent's CPU and memory, while the stale pass called the node's poll current. - A supplemental refresh (`MonitorAdapter.PopulateSupplementalRecords`, and the read-state overlay) of a linked vSphere VM kept the in-guest agent's memory over vSphere's current reading, where a full rebuild from the same records shows vSphere's. ## Change - Snapshot and record ingest hold the caller's thresholds on the registry while they run (the same per-pass pattern as the guest loop's agent index), and `mergeInto` passes them to `mergeMetrics`. The snapshot helpers that reach `mergeInto` keep their signatures. - The stale pass and the metric merge share one threshold rule, `sourceStaleThreshold`, so the merge also honours a sighting's expected update interval (slow Proxmox disk inventory), as the stale pass already did. - Outside mock mode the monitor configures only Proxmox, PBS and PMG, so those are the production sources this changes; mock mode also configures TrueNAS, vSphere and availability. ## Proof - `TestMonitorAdapterSourceMergesUseConfiguredStaleThresholds`: rebuild, supplemental refresh and overlay of a linked vSphere VM, plus a node with an auto-linked agent, through `NewMonitorAdapterWithStaleThresholds`. - `TestSourceMergesJudgeFreshnessByTheIngestStaleThresholds`: snapshot node+agent merge with and without thresholds. - `TestMetricMergeFreshnessMatchesTheStalePass`: the merge and the stale pass agree for default, configured and expected-interval sightings. - Negative control with #2715's `registry.go`: the supplemental, overlay, node+agent, snapshot and expected-interval cases fail; the rebuild case and the defaults case pass on both. - `go test ./internal/unifiedresources/... ./internal/monitoring/... ./internal/api/resourceapi/... ./internal/mock/...` on pulse-dev.
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
