The Thresholds page builds its PUT /api/alerts/config body from the settings it edits. It has no control for flapping detection, alert TTL cleanup or custom rules, so it never sends flappingEnabled, maxAlertAgeDays, maxAcknowledgedAgeDays, autoAcknowledgeAfterHours or customRules. The handler decoded the body into a zero AlertConfig, so every thresholds save turned flapping detection and TTL cleanup off, reset the flapping tuning, dropped custom rules, and persisted that. The page's flapping, aggregation and ioNormalization objects are not AlertConfig fields and never enabled anything. The handler now hands the body to Manager.ApplyConfigUpdate, which reads the stored config, merges and applies it under the manager lock, so two concurrent partial saves cannot revert each other. The body is decoded on its own, so the keys it carries mean exactly what encoding/json makes of them; every top-level field it left out is copied from a JSON round trip of the stored config, sharing no maps with it. ApplyConfigUpdate returns a cloned snapshot, which the handler persists, because SaveAlertConfig normalizes the config it is handed in place and used to write into the live config's maps. Saves run one at a time so alerts.json ends with the last applied config. A body that is not a JSON object, null included, is a 400. Stored configs are not rewritten, so a value an earlier save zeroed stays as it is. On a private stack, a node CPU change saved from the Thresholds page zeroed all four fields in memory and in alerts.json on main; with this change the same save kept them and stored the new threshold.
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
