Operators coming from LibreNMS expect the same figures under a port graph. Add them: - Totals: bytes transferred in and out over the selected range (GraphResponse.totals), integrated from the average rate across the stitched raw and hourly tiers without double counting; partial coverage is flagged. - Summaries read Now / Avg / Max / 95th / Total per direction, plus an aggregate (in+out) 95th (p95.aggregate_bps, hot store only). - Utilisation as a percentage of port speed, and a "% of speed" axis. - "Compare previous period" overlay on the graph view and expanded row. - Errors and discards graphs (GET /api/v1/graph/counters), hot-store range only since they have no rollups. Packet and broadcast/multicast graphs stay disabled: those counters are not polled (DEVIATIONS 56).
