http_3_congestion_window_growth:
type: labeled_counter
description: >
Records if a connection ended with a congestion window higher than the initial window size and if it saw slow start exit (in this case because of a congestion event) before ever growing the congestion window.
Label explanation:
- had_growth: Connection saw congestion window growth
- no_growth: Connection never surpassed the initial window size
- no_growth_but_exit: Connection never surpassed the initial window size but slow start was exited
- no_growth_then_exit_then_growth: Connection exited slow start before then later growing the congestion window past the initial window size
This metric can be used to judge how HTTP3 connections behave in regard to their congestion window and keep an eye on the phenomeon that prompted the filtering on most other congestion control metrics, where we only record connections that had congestion window growth past the initial window.
