Slice 5 (final) of observability-service-registry. Completes the move to
service-registry-only observability config: no observability service env
vars remain.
- config.py: removed alertmanager_url + alertmanager_webhook_url fields.
- docker-compose.yml / docker-compose.dev.yml: removed ALERTMANAGER_URL,
ALERTMANAGER_WEBHOOK_URL (backend env), and VITE_GRAFANA_URL,
VITE_PROMETHEUS_URL (frontend build args / dev env).
- frontend/Dockerfile: removed the VITE_GRAFANA_URL / VITE_PROMETHEUS_URL
ARG, build-stage ENV, and dev-stage ENV lines.
- docs: REQUIREMENTS decision-log entry; CHANGELOG Added/Changed/BREAKING
for the observability service registry; backend/README monitoring
section (Observability page, services page config, http_sd_configs,
new health endpoints, log-only webhook).
The only observability env var remaining is PROMETHEUS_ENABLED (Manage's
own /metrics toggle). Grep-gated: no live references to the removed
vars/fields in backend src, frontend src, compose, or Dockerfile.
ruff clean; 239 backend tests pass; frontend 0 lint errors, build clean,
72 tests pass.
.env.example is assistant-edit-blocked; user follow-up noted in the SDD
tasks: drop the removed vars there too.
The legacy SSH-scraping MonitoringPoller and its endpoints were
decommissioned earlier; update the backend README endpoint list and
Monitoring description to match the current Alertmanager + Prometheus
targets + Grafana observability model.
- backend/ uses proper Python src layout (src/media_library_viewer_api/)
with pyproject.toml, hatchling build, and PYTHONPATH=src convention
- frontend/ is a Vite + React + TypeScript SPA
- archive/ preserves the original Streamlit prototype for reference
- Cleaned up root to only contain docs, license, and subproject dirs
- Updated README for the new dual-subproject architecture
Backend:
- FastAPI app with 17 REST endpoints covering dashboard, monitoring,
media index, file browser, and jobs
- Reuses existing clients/domain/services unchanged
- pydantic-settings config, dependency injection, CORS setup
- Auto-generated OpenAPI docs at /docs
Frontend:
- Vite + React + TypeScript SPA
- @tanstack/react-query for data fetching with polling
- ag-grid-react for media table and file browser
- recharts for monitoring charts
- Tailwind CSS styling
- 4 pages: Dashboard, Monitoring, Media, File Browser
- Typed API client matching all backend endpoints
Also:
- docs/MIGRATION_PLAN.md with full architecture plan
- Updated .gitignore for both subprojects
- Streamlit app preserved for now (can coexist)
