- Add managed NUT mode: configure NUT daemon from Settings → Plugins (UPS plugin), writes /data/nut_managed.json read by entrypoint on restart — no env vars or USB passthrough required - entrypoint.sh: start NUT from /data/nut_managed.json or NUT_MANAGED=1 env var; drop to app user via gosu after NUT daemons start - nut_setup.py: support --from-file <json> in addition to env vars - Dockerfile: add nut, nut-client, gosu packages and entrypoint - docker-compose.yml: document optional NUT_MANAGED env var block - Fix plugin hot-reload migration failure: pass all plugin migration dirs to Alembic so previously-stamped revisions from other plugins remain resolvable (fixes UPS and any plugin with depends_on) - Fix plugin list-type config (e.g. SNMP devices) rendering as broken text input — now shows a read-only note to edit plugin.yaml instead - Fix _sync_nut_managed_config: only write JSON when nut_ups_host is non-empty, preventing NUT startup loop on container restart Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Fabled Scryer
A self-hosted network monitoring and infrastructure management hub for home servers. Fabled Scryer gives you a single pane of glass over your hosts, services, and automation — with live-updating dashboards, alerting, and Ansible integration.
What It Does
- Ping monitoring — TCP/ICMP probes with live latency history and configurable thresholds
- DNS monitoring — resolution checks with optional expected-IP validation
- Ansible — browse playbooks, trigger runs, stream output live
- Alerting — threshold-based rules against any monitored metric, with email and webhook (Discord-compatible) notifications
- Plugins — extend with additional data sources; Traefik metrics included out of the box
- Dashboard widgets — all monitors and plugins contribute live-updating widgets
No JavaScript framework. No build step. No external workers or message brokers.
Quick Start — Docker
cp .env.example .env
# Set FABLEDSCRYER_DATABASE_URL in .env
docker compose up -d
Open http://localhost:5000. On first run you'll be prompted to create the admin account.
Quick Start — Bare Metal
Requires Python 3.11+ and PostgreSQL.
python -m venv .venv && source .venv/bin/activate
pip install -e .
cp config.example.yaml config.yaml
# Edit config.yaml — set database.url at minimum
fabledscryer --host 0.0.0.0 --port 5000
ICMP ping requires CAP_NET_RAW or the setuid ping binary. TCP mode (the default) needs no elevated privileges.
Configuration
Only two things must be set to run the app:
| What | How |
|---|---|
| Database URL | FABLEDSCRYER_DATABASE_URL env var or database.url in config.yaml |
| Secret key | Auto-generated on first run and saved to /data/secret.key |
Everything else — SMTP, webhooks, monitor intervals, Ansible sources, plugin settings — is configured through the web UI at /settings/.
Plugins
Drop a directory into plugins/ and enable it via the Settings UI. The Traefik plugin is included:
plugins/
└── traefik/ ← included; enable in Settings
See docs/plugins/ for a full plugin development guide.
