Hello. With the latest inclusion of the new Metric machinery in ATS 10 you are no longer able to reset|zero a counter at runtime, this used to make sense as the old metrics were persistent, this is no longer the case for ATS 10. All counters are reset on every restart, so this would be the way to clear them all.
Q: Do you guys have any good arguments to (re)implement this "feature"? It does not make sense to implement a feature just to keep backward compatibility when there is no real need. Keep in mind that there are other ways to monitor <https://docs.trafficserver.apache.org/en/latest/appendices/command-line/traffic_ctl.en.html#cmdoption-traffic_ctl-metric-arg-monitor> a metric in case you want to know how this metric performs without the need to reset it. To keep this consistent, in case we do not implement it we would need to remove this(metric clear|zero) API from traffic_ctl for ATS 10. Regards, Damian
