# TCP Byte Counters
#
# Prometheus counters for bytes forwarded over TCP connections in each
# direction, labeled by listener. Totals stay accurate when a session ends
# on an idle timeout or shutdown rather than a clean close. Scraped via the
# admin /metrics endpoint.
#
# Usage:
#   cargo run -p praxis-proxy -- -c examples/configs/observability/tcp-byte-counters.yaml
#
# Exercise:
#   echo "SELECT 1" | nc localhost 5432
#   curl -s http://localhost:9901/metrics | grep tcp_bytes
