Five stores set private page caches of 16 to 64 MB per connection. The modernc driver allocates that cache with anonymous mmap outside the Go heap, so GC and GOMEMLIMIT never see it, and each page costs about twice its size. Measured: reading a 107 MB database through a 64 MB cache_size added 117 MB of resident memory, against 6 MB at SQLite's 2 MB default. On a long-running dogfood install about 165 MB of 360 MB resident sat outside the Go heap, with a 126 MB audit database behind a 64 MB cache (#1803). Audit, RBAC, notification queue, unified resources and the alert event log (writer and both readers) now take pdb.PageCachePragma. Pages that miss it come from the kernel file cache, which the kernel can reclaim. The audit suite, including its large legacy migration, takes the same time as before (309 s on both trees). pkg/db tests reject any other cache_size in production code and bound the resident growth of a 30 MB scan. Each store's test pins its effective value. Negative controls: restoring the audit cache fails the source scan, and a 64 MB reader cache grows a scan by 55 MB against a 16 MB budget. modernc sorts _pragma values before applying them, so a second cache_size in one DSN cannot reliably override.

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.
