-Per-handler Listener Stats
---------------------------
+每个处理程序 (handler) 的监听器统计信息
+--------------------------------------------
 
-Every listener additionally has a statistics tree rooted at *listener.<address>.<handler>.* which
-contains *per-handler* statistics. As described in the
-:ref:`threading model <arch_overview_threading>` documentation, Envoy has a threading model which
-includes the *main thread* as well as a number of *worker threads* which are controlled by the
-:option:`--concurrency` option. Along these lines, *<handler>* is equal to *main_thread*,
-*worker_0*, *worker_1*, etc. These statistics can be used to look for per-handler/worker imbalance
-on either accepted or active connections.
+每个监听器还有一个基于 *listener.<address>.<handler>.* 的统计树，它包含 *per-handler* 的统计信息。如 :ref:`线程模型 <arch_overview_threading>` 文档中所述，Envoy 的线程模型包括主线程以及由 --concurrency 选项控制的多个工作线程。按照这些原则，<handler> 等于 main_thread，worker_0，worker_1 等。这些统计信息可用于寻找接受或活动连接上每个处理程序/工作程序 (handler/worker) 的不平衡状况。
