-## Overview of Custom Logging with Apache Flink
+<a name="overview-of-custom-logging-with-apache-flink"></a>
-Each standalone JobManager, TaskManager, HistoryServer, and ZooKeeper daemon
redirects `stdout` and `stderr` to a file
-with a `.out` filename suffix and writes internal logging to a file with a
`.log` suffix. Java options configured by the
-user in `env.java.opts`, `env.java.opts.jobmanager`,
`env.java.opts.taskmanager`, `env.java.opts.historyserver` and
-`env.java.opts.client` can likewise define log files with
-use of the script variable `FLINK_LOG_PREFIX` and by enclosing the options in
double quotes for late evaluation. Log files
-using `FLINK_LOG_PREFIX` are rotated along with the default `.out` and `.log`
files.
+## Apache Flink 自定义日志概述
-## Profiling with Java Flight Recorder
+每个独立的 JobManager，TaskManager，HistoryServer，ZooKeeper 守护进程都将 `stdout` 和
`stderr` 重定向到名称后缀为 `.out` 的文件，并将其内部的日志记录写入到 `.log` 后缀的文件。用户可以在
`env.java.opts`，`env.java.opts.jobmanager`，`env.java.opts.taskmanager`，`env.java.opts.historyserver`
和 `env.java.opts.client` 配置项中配置 Java 选项（包括 log 相关的选项），同样也可以使用脚本变量
`FLINK_LOG_PREFIX` 定义日志文件，并将选项括在双引号中以供后期使用。日志文件将使用 `FLINK_LOG_PREFIX` 与默认的
`.out` 和 `.log` 后缀一起滚动。

+
+Java Flight Recorder 是 Oracle JDK 内置的分析和事件收集框架。[Java Mission
Control](http://www.oracle.com/technetwork/java/javaseproducts/mission-control/java-mission-control-1998576.html)
是一套先进的工具，可以对 Java Flight Recorder 收集的大量数据进行高效和详细的分析。配置示例：
{% highlight yaml %}
env.java.opts: "-XX:+UnlockCommercialFeatures -XX:+UnlockDiagnosticVMOptions
-XX:+FlightRecorder -XX:+DebugNonSafepoints
-XX:FlightRecorderOptions=defaultrecording=true,dumponexit=true,dumponexitpath=${FLINK_LOG_PREFIX}.jfr"

and visualizer for the Java HotSpot JIT
-compiler used to inspect inlining decisions, hot methods, bytecode, and
assembly. Example configuration:
+[JITWatch](https://github.com/AdoptOpenJDK/jitwatch/wiki) Java HotSpot JIT
编译器的日志分析器和可视化工具，用于检查内联决策，热方法，字节码和汇编。配置示例：
{% highlight yaml %}
env.java.opts: "-XX:+UnlockDiagnosticVMOptions -XX:+TraceClassLoading

-## Analyzing Out of Memory Problems
+<a name="analyzing-out-of-memory-problems"></a>
-If you encounter `OutOfMemoryExceptions` with your Flink application, then it
is a good idea to enable heap dumps on out of memory errors.
+## 分析内存溢出问题（Out of Memory Problems）
+
+如果你的 Flink 应用程序遇到 `OutOfMemoryExceptions` ，那么启用在内存不足错误时堆转储是一个好主意。
