Two Proxmox connections can each have a node with the same name, which
is common for MSPs running one `px1` per site. With one host agent
linked to site A's `px1`, `getHostAgentTemperatureByID("siteB-px1",
"px1")` returned site A's temperature. The hostname fallback took the
first agent with that hostname, even one linked to another node, and
even when the name was ambiguous enough that the agent linker had
refused to link it. The cluster sensor cache leaked the same way: SSH
readings an agent collects for its cluster siblings were keyed by bare
node name. Site B's `px1` then showed, alerted on and recorded history
for another machine's sensors.
## Change
- The poller hands the lookup the polled node
(`getHostAgentTemperatureForNode`,
`carriedTemperatureOutlivesAgentLease`), and the lookup works on that
node's **slot**: its own source ID, plus, when the read state does not
hold that ID, the one same-named node proven to be the same machine.
- The state folds the views of one machine reached through two
connections (a cluster added twice, or a multi-homed host added by each
address) into a single node kept under one view's ID, and an automatic
agent link follows it. A narrowed fallback on its own would leave those
views without a temperature permanently; that was reproduced with real
`UpdateNodesForInstance` folds.
- Same-machine proof comes from the state's own evidence: new
`models.NodeObservationsSameMachine` and
`models.HostAgentBridgesNodeViews`
(`internal/models/node_machine_identity.go`). `UpdateNodesForInstance`'s
agent-corroboration check now shares its rule with them. Two or more
candidates are ambiguous and none is taken, as the state declines an
ambiguous alias.
- An agent linked to the slot is the node's agent. The hostname fallback
only takes an agent with no node, VM or container link, and only when no
node outside the slot and no second unlinked agent has the name.
- Cluster sensor cache entries record their reporting agent. A reading
serves a node only when that agent's linked node shares one of the
slot's connections, or belongs to a connection whose configured view of
the node has a matching TLS fingerprint (the other connection of a
cluster added twice).
`LinkedNodeID` holds the Proxmox source node ID for every link source
(automatic `findLinkedProxmoxEntityWithHints` → `NodeView.SourceID()`,
manual `LinkHostAgentToNode` validating against `models.Node.ID`,
reconciliation, continuity restore), so the link match needs no
namespace normalization. A manual link stays pinned to the ID the
operator chose (the state never transfers intent to a replacement
provider identity), so a node held under the other view's ID has no
linked agent. The physical-disk SMART merge already matches by
`node.LinkedAgentID` within one instance and is unchanged.
## Tests
- `TestNodeTemperatureStaysWithinSameNamedNodesSite` (registered
monitoring proof, `monitor_additional_test.go`), through
`collectNodeTemperatureData` against registry-backed and state-folded
read states: agent linked to the other site's node; ambiguous unlinked
agents; unambiguous unlinked agent (still served); cluster added through
two connections (alternating real state folds); multi-homed host via two
standalone connections; ambiguous address alias; a namesake agent with a
contradicting fingerprint; sibling readings across both connections of
one cluster; sibling reading from the other site. The leaking cases fail
on main, and each folded-view guard was checked with an overlay negative
control.
- `TestApplyHostReportScopesClusterSensorsToReportersConnection`
(`monitor_host_agents_test.go`): real `ApplyHostReport` ingest of
cluster sensors.
- `TestNodeObservationsSameMachineMatchesStateFold` and
`TestHostAgentBridgesNodeViewsMatchesStateFold` pin the predicates
against `UpdateNodesForInstance`'s actual fold.
- Full `internal/monitoring`, `internal/models` and
`internal/unifiedresources` pass on pulse-dev.

- 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.

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.
