public interface ReplayStatisticsMXBean

An MXBean that exports various runtime statistics about Application Continuity (AC), such as how many JDBC calls are affected by outages, how many replay attempts are made, how many replay succeed, etc. This interface provides query-only operations on all available AC statistics.
