# Landing stats.json freshness (outside-in; age via generated_at_unix)
STATS_STALE_SECS=900 STATS_FAIL_SECS=3600 ./taler-monitoring.sh -d stage.lefrancpaysan.ch urls
```
### Landing `stats.json` (www.stats)
Public `GET …/intro/stats.json` must expose timestamps so monitoring can tell
whether the collector is still updating:
| Field | Role |
|-------|------|
| `generated_at_unix` | epoch seconds — **preferred** for age = now − unix |
| `generated_at` | ISO-8601 (fallback if unix missing) |
| `generated_at_human` | UI “updated” / footer string |
Also checks display payloads (bank-shape `withdraws` / accounts, or exchange-db /
merchant-db counters). Soft WARN if age > `STATS_STALE_SECS` (default 900);
ERROR if age > `STATS_FAIL_SECS` (default 3600; set `0` to disable).
Stage shared feed: same `gen_unix` on bank + exchange + monnaies.
## Domain profiles (`domains.conf`)
Each monitored stack must say **what is bank, exchange, and merchant-backend**.
