Since #2991 stopped guessing a PMG backup node from the connection name, a failed `/config/cluster/status` read leaves no node to ask for backups, and the poller still published that empty result. `UpdatePMGBackups` replaces the instance's whole list, so one transient cluster-status failure, or every node's backup read failing, wiped every known PMG backup and the Backups view flapped empty until the next good poll. Only a node whose backup list was read is now authoritative for that cycle. Nodes that were not read (every node after a failed cluster read, a node whose backup read failed, or one a cancelled poll never reached) keep their previous backups. This is the same per-scope carry the PVE storage backup poller applies to failed storages (`preserveFailedStorageBackups`). A node that answered with no backups, or that a successful cluster read no longer lists, still clears its entries. The failed read is still recorded as a poll failure. #2991's rule against guessing node names is unchanged. Tests in `monitor_pmg_test.go`: the three retention tests fail on main and pass with this change. A complete enumeration that returns no backups still clears the list. The monitoring subsystem contract now records the carry (new section "PMG backups keep last-known entries for unread nodes"), and the #2960 note no longer says a failed cluster read publishes an empty backup list. Replaces #3005, rebuilt on current main with the contract note.
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.
Need help with a failure? Read the safe reporting guidance before sharing evidence. A second reproduction or diagnostics export is not required; keep the original evidence if another attempt could interrupt workloads or send duplicate notifications. GitHub reports and attachments are public: review them locally and keep credentials and private details out.
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.
