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).
