Description

Jetty version 9.4.x

Description ConnectionStatistics gathers statistics from the connections only when they are closed.

This is not optimal for benchmarks that perform a run, but then keep connections open.

It would be great if ConnectionStatistics (or perhaps another class, say DynamicConnectionStatistics) had a mode where upon an API call (e.g. DynamicConnectionStatistics.collect()) would run through the open connections and gather the statistics from them.

Research direction
Examine the existing ConnectionStatistics class (likely in jetty server module) to understand how it collects statistics on close. Investigate the connection lifecycle to find a way to iterate over open connections and collect their current stats. Consider whether to extend ConnectionStatistics or create a new class. Look at any linked comments for prior discussion.
