Descrizione
Title: Request for improved details surrounding stats and metrics documentation
Description: When customers are debugging issues such as connection resets failures (Contour/Envoy) deployment there have been requests for more in depth descriptions for metrics and statistics that are available in Envoy and documented on the Envoy page.
One example of this is the “upstream_cx_destroy_with_active_rq” metric. It is defined as "Total connections destroyed with 1+ active request". Also found an older issue where a similar request was made, specific to this metric, https://github.com/envoyproxy/envoy/issues/6455
A second example is the "upstream cx_open" stat, but it is not clear how connections are managed, when are they closed when are the reused, etc.
This request is general but provides two examples.
