# Upstream Requests Total
#
# Prometheus counter for requests that reached an upstream endpoint,
# labeled by cluster, endpoint and status class. Requests answered by the
# proxy itself are excluded, so the gap against praxis_http_requests_total
# is proxy-generated traffic. Scraped via the metrics listener.
#
# Usage:
#   cargo run -p praxis-proxy -- -c examples/configs/observability/upstream-requests-total.yaml
#
# Exercise:
#   curl -s http://localhost:8080/api/hello
#   curl -s http://localhost:9902/metrics | grep upstream_requests_total
