PR 2 of 4 for the runtime service registry change.
- dashboard_widgets gains service_id + widget_kind columns (legacy
addon_id/widget_type kept but unused).
- Source adapters take (service: ServiceRecord | None, widget_kind, config).
SERVICE_ADAPTERS keyed by service_type; BUILTIN_ADAPTERS for backups/static.
- Backups and static stay as service-less built-ins (service_id nullable),
exposed via GET /api/widgets/builtin.
- SSH task adapter resolves the task + instance, runs over SSH, and appends a
service_task_runs history row on success/failure/timeout/error.
- Retire widgets/registry.py; widget metadata now comes from the integrations
registry + widgets/builtin. Remove /api/widgets/types and /api/widgets/sources.
- Stop default widget seeding (fresh install = empty dashboard).
- Rewrite widget tests around the service-bound + built-in model (26 tests).
Backend-only breaking change; frontend is reconciled in Slice 3. Build/lint
stay green; pytest 222 passed.
- Refresh README feature list and remove references to the legacy
in-app monitoring charts / backend poller.
- Document configurable dashboard widgets, addon pages, and widget env vars.
- Add VITE_PROMETHEUS_URL support to frontend Dockerfile and both compose files.
- Add header comment to .env.example explaining shell-export workflow.
- Update remote server requirements to match current capabilities.
PR 4 of 4 for configurable dashboard widgets.
- Replace hard-coded Jellyfin/Backups dashboard sections with a loop that
renders enabled widget instances by sort_order.
- Add WidgetInstance renderer and WidgetConfigDialog for adding, editing,
enabling/disabling, deleting, and reordering widgets.
- Add addon pages for grafana, prometheus, and ssh-tasks at /addons/:addonId.
- Register /addons/:addonId route in App.tsx.
- Update docs/REQUIREMENTS.md with the widget system design and API.
Verification:
- backend ruff clean; pytest 200 passed
- frontend npm run lint: 0 errors
- frontend npm run build: success
- frontend npm run test -- src/widgets/registry.test.ts: 3 passed
- Remove GRAFANA_URL from backend environment (backend never consumed it).
- Add VITE_GRAFANA_URL to frontend build-args (prod), dev environment, and
frontend/Dockerfile ARG/ENV so Grafana deep-links resolve correctly.
- Add ALERTMANAGER_WEBHOOK_URL to backend environment so the documented
alert-forwarding feature is reachable from compose.
- Document VITE_GRAFANA_URL in .env.example.
Update docs to reflect that Manage no longer scrapes its own system
metrics (slices 1-2). AGENTS.md, REQUIREMENTS.md (decision log +
observability section), monitoring-logging-design.md, MIGRATION_PLAN.md.
Gate: docs only; backend pytest (173) + frontend build/lint/test (22/63)
remain green from slices 1-2.
The 2026-06-16/17 observability update externalised metrics to
Prometheus + node_exporter + Grafana, but the legacy Manage-side
SSH-scraping monitor was never removed. It duplicated the new stack,
ran SSH df on every machine every 300s, and fed nothing (its UI was
deleted in e2ad731). This slice decommissions the duplication.
Removed (backend):
- services/monitoring_poller.py (MonitoringPoller) — entire file
- services/monitoring_actions.py (disk_space, run_machine_operation,
poll_machine_snapshot, build_machine_client) — entire file;
run_machine_operation had only 2 callers (the poller + /disk), both gone
- tests/test_monitoring_actions.py
- endpoints: POST /api/monitoring/poller, GET /machines/{id}/actions,
GET /disk (and the now-dead _resolve_machine helper)
- lifespan wiring (main.py), dependency wrapper (dependencies.py),
poller.start()/kick() from machine save (routers/settings.py)
- SettingsStore: monitoring_machine_actions table CREATE + 2 indexes +
record/list/prune_machine_actions methods; DROP TABLE IF EXISTS on
startup cleans existing DBs (user-approved)
- config knobs: monitoring_poll_interval_seconds,
monitoring_poll_initial_delay_seconds, monitoring_action_retention_days
- test_api.py: TestMonitoring._ensure_machine + test_disk
Kept (fits the new model): /machines, /prometheus-targets, /alerts,
/alertmanager-status, /alertmanager-webhook; the disk_usage JOB template
(manual on-demand, not monitoring); node_exporter_* machine fields
(they point Prometheus at the right host).
Gate: backend pytest 173 passed; ruff clean.
Move the completed, verified, synced change folder to the dated archive:
openspec/changes/web-ui-rework/ -> openspec/changes/archive/2026-06-17-web-ui-rework/
Canonical spec stays in place at openspec/specs/web-ui/spec.md (not moved).
This is the physical archive step deferred (documented-pending-manual) in
archive-report.md ec46e26; user-approved.
Web UI rework. Completes the DataGrid migration (7a + 7b):
- pages/Media.tsx off @mui/x-data-grid + @mui/material onto DataTable:
15 locked columns (title/series/season/episode/type/year/runtime_min/
size/bitrate/hdr/video/resolution/date_added/library/path);
enablePagination + manualPagination + rowCount from queryResult.total;
page state (pageIndex/pageSize) -> offset/limit into useMediaQuery;
onRowClick -> navigate('/files?path=...') preserved; stable path-derived
getRowId so selection survives server paging; column-visibility toggle.
Hard rule honored: NO sorting, NO resizing (visibility-only).
- Migrate Media shell (Select/Input/Progress/Card/grid/Typography/Tabs).
- Media component tests (column set + row-click nav).
- Harness fix: polyfill ResizeObserver in test/setup.ts — jsdom lacks it
and Radix primitives (Select/ScrollArea/etc.) reference it; was causing
cross-test failures once Media pulled shadcn Select into the pool.
Gate: build + lint + test green (23 files / 64 tests).
- Replace OBSERVABILITY_DATA_ROOT with per-service *_ROOT variables in
docker-compose.observability.yml.
- Each service root must contain config/ (mounted read-only) and data/
(mounted read-write), grouping config and state together for Portainer.
- Update docs/observability-runbooks.md with the new variables, a setup
script that copies repo configs into each service root, and updated
backup/restore examples.
- Make OBSERVABILITY_DATA_ROOT required in docker-compose.observability.yml
so Portainer deployments must set an absolute host path.
- Add Traefik labels and the web external network to Grafana, Prometheus,
and Alertmanager with env-driven hostnames, router/service names,
internal ports, entrypoint, and cert resolver.
- Keep direct host ports as a fallback for local debugging.
- Update docs/observability-runbooks.md with required variables,
Traefik hostname column, and a .env.observability example.
- Switch docker-compose.observability.yml from named volumes to host
bind mounts under OBSERVABILITY_DATA_ROOT, defaulting to
./observability-data.
- Make all service ports configurable via environment variables
(PROMETHEUS_PORT, LOKI_PORT, ALLOY_PORT, GRAFANA_PORT,
ALERTMANAGER_PORT, NODE_EXPORTER_PORT).
- Add VITE_GRAFANA_URL handling to ObservabilityPage so Grafana links
point to the configured standalone instance.
- Update docs/observability-runbooks.md with the env variable table,
reachable-web-UI table, and backup/restore instructions for the new
host-directory layout.
- Replace embedded Grafana iframes in ObservabilityPage with external
Grafana link cards. Grafana URL is configurable via VITE_GRAFANA_URL
(frontend) or GRAFANA_URL (backend env exposed to frontend build).
- Remove the grafana scrape job from monitoring/prometheus/prometheus.yml
so the main Prometheus stack no longer depends on Grafana.
- Pass GRAFANA_URL through docker-compose.yml and docker-compose.dev.yml.
Add docker-compose.observability.yml to run Grafana, Prometheus, Loki,
Alertmanager, Alloy and Node Exporter independently of Manage.
Includes a standalone Prometheus config, empty file-SD placeholder,
and runbook documentation.
The dark mode button was toggling React state but never applying it to the
DOM. Add a useDarkMode hook that:
- Persists the preference in localStorage
- Defaults to the OS prefers-color-scheme on first visit
- Adds/removes the 'dark' class on <html> to trigger CSS variable overrides
Also add dark-mode color overrides for all Tailwind v4 theme variables in
index.css.
