Add ledgerCumulativeTxBytes to LedgerQueries and wire it through LedgerMetrics so that the periodic ledger metrics trace emits an IntM "cumulativeTxBytes" gauge. This creates a Prometheus metric cardano_node_metrics_cumulativeTxBytes_int that can be used with rate() to compute confirmed tx throughput (txkB/s). The field is read from shelleyCumulativeTxBytes on the ShelleyLedgerState (added in ouroboros-consensus on the cumulative-tx-size branch). Byron returns 0. Picks up shelleyCumulativeTxBytes, the new top-level field on ShelleyLedgerState that tracks cumulative transaction bytes on the selected chain.
