Runtime
Counters held in this process, not in the database: they start at zero when the proxy starts and are lost on restart. Everything above comes from the database instead, and survives a restart — so a low count here alongside a large one above just means the proxy started recently.

Request sources
Per-caller addresses are off. Set ui_request_sources: true
to show them here, once /ui is behind authentication;
the per-request detail is in the access log.

Pre-cache scanning
Not configured. Enable it under scanning in the
config to have artifacts scanned before they are committed to the cache.
Every figure on this page is also exported for Prometheus at
/metrics.
This page shows current state only — nothing here is a time series. For history,
trends and alerting, scrape /metrics and use the
Grafana dashboard shipped in deploy/grafana/.
