- Q4 → Obsidian vault is the Notizen/ folder in Nextcloud (multi-device sync). Nexa reads via WebDAV using the existing NC_APP_PASSWORD — no filesystem mount. Ignore list pinned: .copilot/, .copilot-index/, .smart-env/, .caldav-sync/, assets/ (routed to Phase-3.2 visual queue), Templates/, BMO/, Excalidraw/. Index target: Notizen/**/*.md. - Q5 → canonical name is Karakeep; legacy Zoraxy alias hoarder.nuclide.systems kept for compatibility. - Q13 → Octoprint container is intentionally powered down most of the time. Phase-5 monitoring must skip names matching octoprint*. Reflected in docs/10 monitoring table and CLAUDE.md. - Q14 → Homepage Zoraxy widget config error; cosmetic, dropped from open questions and from docs/12 optimization list. - Q18 → SAIA does proxy embeddings but rate limit is 10 msg/min, unusable for ingest. TEI stays in Phase 3.1. - docs/12: stale items removed (Octoprint, Zoraxy widget, generic Immich vector idea); added new ones derived from the Obsidian discovery (plugin embedding collision, notify_push upgrade path, assets/ size note). - docs/04 integration matrix updated to describe Obsidian-via-Nextcloud read path explicitly. - docs/09 step-4 credentials list collapses NC Tasks / Calendar / WebDAV onto a single app password.

# 10 — Operations

|
Day-2 concerns. Backups, monitoring, troubleshooting.
|
|
|
|
## Backups
|
|
|
|
Backrest (LXC 103) already handles file-level snapshots. Add Nexa-specific items:
|
|
|
|
| What | How | Frequency |
|
|
|------|-----|-----------|
|
|
| n8n workflow JSON | `nexa-core/scripts/backup_workflows.sh` → git push | hourly cron in n8n container |
|
|
| Qdrant `nexa_knowledge` | `POST /collections/nexa_knowledge/snapshots` → rsync to `s3.nuclide.systems` | daily (Backrest pre-hook) |
|
|
| Memos DB | Backrest snapshot of Memos data dir | already covered |
|
|
| Nextcloud | Nextcloud's own backup app + Backrest of `/var/www/nextcloud/data` | already covered |
|
|
| `runtime_config.json` (Qdrant `_config` namespace) | Qdrant snapshot covers it | n/a |
|
|
|
|
## Monitoring
|
|
|
|
| Signal | Source | Sink |
|
|
|--------|--------|------|
|
|
| Container up/down | Dozzle (`192.168.1.40:3553`) + docker healthchecks. **Skip names matching `octoprint*`** — that container is intentionally powered down most of the time. | Memos system feed via ntfy |
|
|
| n8n workflow failures | n8n built-in failure-webhook | ntfy → `nexa.system` topic |
|
|
| Proxmox / disk / memory alerts | Proxmox notification target → ntfy | ntfy → Memos digest |
|
|
| LiteLLM rate-limit | LiteLLM logs / cost-tracking | Memos morning digest |
|
|
| Backrest run status | Backrest webhook | ntfy |
|
|
|
|
A **single ntfy topic `nexa.system`** is the convention; n8n has one workflow that re-broadcasts it as a Memos comment under a pinned `[SYSTEM]` memo.
|
|
|
|
## Troubleshooting
|
|
|
|
### Memos webhook not firing
|
|
|
|
```bash
|
|
# is the Memos webhook config still pointing at n8n?
|
|
curl -s -H "Authorization: Bearer $MEMOS_API_KEY" \
|
|
https://memos.nuclide.systems/api/v1/workspace/setting | jq '.webhooks'
|
|
|
|
# does n8n still expose the path?
|
|
curl -i https://n8n.nuclide.systems/webhook/memos # expect 200/405, never 404
|
|
```
|
|
|
|
If 404 → workflow is inactive in n8n. Activate.
|
|
|
|
### LiteLLM 401 / 429
|
|
|
|
- 401 → the Nexa virtual key was rotated. Reissue, update `.env`, re-create the n8n credential.
|
|
- 429 → set per-key TPM/RPM limits in LiteLLM admin; classification calls are tiny (<300 tok), embeddings are the bulk.
|
|
|
|
### Qdrant `nexa_knowledge` empty
|
|
|
|
```bash
|
|
# is the indexing workflow active?
|
|
docker logs nexa-n8n 2>&1 | grep memos_bridge | tail
|
|
|
|
# manual index test
|
|
curl -X POST https://memos.nuclide.systems/api/v1/memos \
|
|
-H "Authorization: Bearer $MEMOS_API_KEY" \
|
|
-d '{"content":"manual probe #nexa"}'
|
|
|
|
# point count
|
|
curl -s -H "api-key: $QDRANT_API_KEY" \
|
|
$QDRANT_HOST/collections/nexa_knowledge | jq '.result.points_count'
|
|
```
|
|
|
|
### Wrong list routing (Work vs Personal)
|
|
|
|
1. Run `#nexa:route-test <text>` and check the confidence value.
|
|
2. If <0.7 the router defaults to Personal (by design — see [06](./06-classification-logic.md)).
|
|
3. Tune the system prompt in `nexa-core/ai-prompts/system_prime.txt`; commit the change.
|
|
|
|
### "Where did Nexa store this?"
|
|
|
|
```bash
|
|
# state dump
|
|
curl -X POST https://memos.nuclide.systems/api/v1/memos \
|
|
-d '{"content":"#nexa:export-state"}'
|
|
# returns runtime_config + counters as a JSON memo
|
|
```
|
|
|
|
## Log locations
|
|
|
|
| Component | Where |
|
|
|-----------|-------|
|
|
| Memos | `docker logs nexa-memos` (LXC 104) |
|
|
| n8n | `docker logs nexa-n8n` |
|
|
| LiteLLM | `docker logs litellm` |
|
|
| Qdrant | `docker logs qdrant_scientific` |
|
|
| Zoraxy | LXC 108 web UI → Statistical Analysis |
|
|
| Backrest | LXC 103 web UI |
|
|
|
|
For a one-shot dump:
|
|
|
|
```bash
|
|
ssh nuc 'docker compose -p nexa logs --tail 500' > /tmp/nexa.log
|
|
```
|
