# Prometheus gauge for TCP connections currently open per listener.
# Incremented on accept and decremented when the session ends, including
# early closes such as connect failures. Scraped via the admin /metrics
# endpoint.
#
# Usage:
#   cargo run -p praxis-proxy -- -c examples/configs/observability/tcp-active-connections.yaml
#
# Exercise:
#   echo "hi" | nc localhost 5432
#   curl -s http://localhost:9901/metrics | grep tcp_active_connections
