Background collector samples CPU/memory/network/block I/O for every
instance and site on a configurable interval (default 15s, range
5-300s), persists samples to SQLite with a configurable retention
window (default 2h, range 0-24h), and skips ticks gracefully when
the Docker daemon is unreachable. Settings are reloadable without
a restart — each tick re-reads them.
New API endpoints:
- GET /api/system/stats (host snapshot: info + df)
- GET /api/system/stats/history
- GET /api/system/stats/top?by=cpu|memory
- GET /api/projects/{id}/stages/{s}/instances/{iid}/stats/history
- GET /api/sites/{id}/stats[/history]
- GET /api/sites/{id}/logs (SSE + JSON, reuses instance log streamer)
Frontend:
- ECharts added with tree-shaken imports (~180KB gzip) for
future-proof time-series/gantt/graph visualizations
- CollapsibleSection wraps all dashboard sections (system health,
daemons, system resources, static sites, projects) with
localStorage-persisted open state
- SystemResourcesCard shows capacity tiles, workload utilization
chart with 30m/2h/6h/24h window picker, disk breakdown with
reclaimable callouts, and top 5 consumers
- ContainerStats and ContainerLogs take a source discriminated union
so sites reuse the same components as instances; sites detail page
embeds both for Deno backend debugging
- Settings › Maintenance exposes collection interval + retention
- Docker-unavailable state returns 503 and renders an amber banner
instead of a generic 500
Full i18n coverage (en + ru) for all new strings.
- Health API now surfaces Docker /info + /version (version, platform,
kernel, container/image counts, storage driver, memory, latency) and
NPM aggregates (proxy host total, managed-by-Tinyforge count, access
lists, certificates, endpoint URL).
- Docker/NPM indicators moved out of the sidebar footer and into a
compact mono-styled rail directly under the Tinyforge brand title,
with pulse/fault animations and click-to-expand error hints.
- New SystemDaemonsCard on the dashboard: two terminal-styled panels
(Docker Engine + Proxy) with a running/paused/stopped stacked bar,
key-value diagnostics, and a total-vs-managed proportion meter on
the proxy-hosts tile.
- Shared health store so the sidebar and dashboard share a single
30 s poll instead of duplicating traffic.
- User-facing timezone preference with auto-detect fallback; all
dates across projects, sites, stacks, settings, backup, event log
and stale containers now render through \$fmt.date / \$fmt.datetime.
- en/ru translations for both features.
Promotes the Forge visual language from the Stacks feature into a
global design system used across the app:
- app.css: Forge utilities (dot-grid backdrop, eyebrow, ember,
display/lede, status pills, stat grid, panels, registration
marks, alert, terminal, buttons). CSS variables alias the forge
display font to the app's standard sans stack (Inter, now
properly self-hosted via @fontsource/inter).
- +layout.svelte: reskinned sidebar brand, active nav rail,
mobile top bar, global h1/h2 typography overrides, main dot-grid
backdrop.
- Shared components reskinned: EmptyState (breathing-ember empty
mark), StatusBadge (mono pills with pulse), ConfirmDialog
(registration marks + forge buttons).
- Dashboard (+page.svelte): ForgeHero header, forge-stat-grid,
Instrument-style section titles with accent.
- New ForgeHero component for reusable hero headers.
Stacks feature fully localized (EN + RU):
- 80+ keys under stacks.* covering list, new, detail, revisions,
logs, errors, status labels, delete/rollback dialogs.
- Russian uses forge vocabulary (куются/наковальня/куём/etc).
- $t() wired through all three Stacks pages.
- Add concurrency limiter (max 4 GET requests) to API layer, leaving
slots for SSE and health checks. Write ops bypass the limiter.
- Add AbortController to ContainerStats, project detail page, and
dashboard to cancel in-flight requests on navigation/unmount.
- Move global SSE connection from layout to events page (only consumer).
- Add 30s heartbeat to SSE endpoint to detect zombie connections.
- Serialize dashboard project fetches to avoid parallel burst.
- Rebuild frontend in dev-server.sh so go:embed stays in sync.
- Add SSE connection status banner showing when real-time updates are lost (UX-H8, UX-M1)
- Add password visibility toggle on login page (UX-H10)
- Add dark mode variants to stat card backgrounds (UX-M11)
- Add overflow-x-auto to tables for mobile responsiveness (UX-H9)
- Add flex-wrap to stage header for mobile overflow (UX-H11)
- Fix theme store system preference listener reactivity (UX-M12)
- Parallelize registry health checks (UX-L4)
Add all frontend pages for observability & proxy management:
- Proxy Viewer: /proxies with grouped view, filtering, health indicators
- Proxy Creation: form with live validation, diagnostic hints, edit/delete
- Stale Containers: /containers/stale with dashboard widget, cleanup actions
- Event Log: /events with filters, pagination, real-time SSE streaming
- Navigation: proxies and events links in sidebar
- i18n: full EN/RU translations for all new features
- Settings: stale threshold configuration
- Append auth token as query parameter to EventSource URLs
(EventSource API doesn't support custom headers)
- Add null guards for stages arrays from API responses
- Hide sidebar on login page
Design system with CSS custom properties (light/dark themes).
38 Lucide SVG icon components. Dark mode with system preference.
EN/RU localization with i18n store. Skeleton loaders, empty states,
toggle switches, micro-interactions. Responsive sidebar with
mobile hamburger menu. All pages polished with consistent styling.
