# TCP Connection Metrics
#
# Prometheus histogram for TCP connection duration. Each completed
# connection is recorded in praxis_tcp_connection_duration_seconds
# with a listener label. Scraped via the admin /metrics endpoint.
#
# Usage:
#   cargo run -p praxis-proxy -- -c examples/configs/observability/tcp-connection-metrics.yaml
#
# Exercise:
#   echo "hello" | nc localhost 5432
#   curl -s http://localhost:9901/metrics | grep tcp_connection_duration
