MutexStats

admin.v3.MutexStats

Proto representation of the statistics collected upon absl::Mutex contention, if Envoy is run under --enable-mutex-tracing. For more information, see the absl::Mutex [docs](https://abseil.io/about/design/mutex#extra-features).

NB: The wait cycles below are measured by absl::base_internal::CycleClock, and may not correspond to core clock frequency. For more information, see the CycleClock [docs](https://github.com/abseil/abseil-cpp/blob/master/absl/base/internal/cycleclock.h).
