## 打印GC与时间戳
- 参数
- -XX:+PrintGCDateStamps
```basic
-XX:+PrintGCDateStamps
Enables printing of a date stamp at every GC. By default, this option is disabled.
- 示例
GC事件文件输出
- 作用
- 设置详细 GC 事件信息应重定向到哪个文件以进行日志记录
- 参数
- -Xloggc:filename
-Xloggc:filename
Sets the file to which verbose GC events information should be redirected for logging. The information written to this file is similar to the output of -verbose:gc with the time elapsed since the first GC event preceding each logged event. The -Xloggc option overrides -verbose:gc if both are given with the same java command.
Example:
-Xloggc:garbage-collection.log
打印GC任务信息
- 作用
- 为每个单独的 GC 工作线程任务启用时间戳打印。默认情况下，此选项处于禁用状态。
- 参数
- -XX:+PrintGCTaskTimeStamps
-XX:+PrintGCTaskTimeStamps
Enables printing of time stamps for every individual GC worker thread task. By default, this option is disabled.

Enables printing of how much time the pause (for example, a GC pause) lasted. By default, this option is disabled.
- 示例
Total time for which application threads were stopped: 0.0350945 seconds, Stopping threads took: 0.0000198 seconds Total time for which application threads were stopped: 0.1184747 seconds, Stopping threads took: 0.0000210 seconds Total time for which application threads were stopped: 0.1984138 seconds, Stopping threads took: 0.0000202 seconds Total time for which application threads were stopped: 0.3010387 seconds, Stopping threads took: 0.0000230 seconds Total time for which application threads were stopped: 0.3996448 seconds, Stopping threads took: 0.0000230 seconds Total time for which application threads were stopped: 0.1051665 seconds, Stopping threads took: 0.0000277 seconds Total time for which application threads were stopped: 0.8984151 seconds, Stopping threads took: 0.0000276 seconds
打印自上次GC以来经过的时间
- 说明
- 启用打印自上次暂停（例如，GC 暂停）以来经过的时间。默认情况下，此选项处于禁用状态。
- 参数
- -XX:+PrintGCApplicationConcurrentTime
-XX:+PrintGCApplicationConcurrentTime
Enables printing of how much time elapsed since the last pause (for example, a GC pause). By default, this option is disabled.
- 示例
Application time: 0.0832210 seconds Application time: 0.0247668 seconds Application time: 0.0891454 seconds Application time: 0.0323655 seconds Application time: 0.0886806 seconds Application time: 0.0769831 seconds Application time: 0.0742674 seconds
打印新生代对象晋升老年代时的年龄
- 参数
- -XX:+PrintTenuringDistribution
-XX:+PrintTenuringDistribution
Enables printing of tenuring age information. The following is an example of the output:
Desired survivor size 48286924 bytes, new threshold 10 (max 10)
- age 1: 28992024 bytes, 28992024 total
- age 2: 1366864 bytes, 30358888 total
- age 3: 1425912 bytes, 31784800 total
...
Age 1 objects are the youngest survivors (they were created after the previous scavenge, survived the latest scavenge, and moved from eden to survivor space). Age 2 objects have survived two scavenges (during the second scavenge they were copied from one survivor space to the next). And so on.
In the preceding example, 28 992 024 bytes survived one scavenge and were copied from eden to survivor space, 1 366 864 bytes are occupied by age 2 objects, etc. The third value in each row is the cumulative size of objects of age n or less.
By default, this option is disabled.
内存溢出相关
内存溢生成转储
- 作用
- java.lang.OutOfMemoryError引发异常时，通过使用堆分析器 (HPROF) 启用将 Java 堆转储到当前目录中的文件。您可以使用该-XX:HeapDumpPath选项显式设置堆转储文件路径和名称。默认情况下，此选项处于禁用状态，并且在OutOfMemoryError引发异常时不会转储堆。
参数
- -XX:+HeapDumpOnOutOfMemoryError
-XX:+HeapDumpOnOutOfMemoryError Enables the dumping of the Java heap to a file in the current directory by using the heap profiler (HPROF) when a java.lang.OutOfMemoryError exception is thrown. You can explicitly set the heap dump file path and name using the -XX:HeapDumpPath option. By default, this option is disabled and the heap is not dumped when an OutOfMemoryError exception is thrown.堆转储路径配置
- -XX:+HeapDumpOnOutOfMemoryError
作用
- 设置该-XX:+HeapDumpOnOutOfMemoryError选项时，设置用于写入堆分析器 (HPROF) 提供的堆转储的路径和文件名。默认情况下，该文件在当前工作目录中创建，并命名为java_pidpid.hprof，其中pid是导致错误的进程的标识符。
- 参数
- -XX:HeapDumpPath=dir
-XX:HeapDumpPath=path
Sets the path and file name for writing the heap dump provided by the heap profiler (HPROF) when the -XX:+HeapDumpOnOutOfMemoryError option is set. By default, the file is created in the current working directory, and it is named java_pidpid.hprof where pid is the identifier of the process that caused the error. The following example shows how to set the default file explicitly (%p represents the current process identificator):
-XX:HeapDumpPath=./java_pid%p.hprof
The following example shows how to set the heap dump file to /var/log/java/java_heapdump.hprof:
-XX:HeapDumpPath=/var/log/java/java_heapdump.hprof
溢出时执行脚本
- 作用
- 内存溢出后执行一个脚本文件
- 参数
- -XX:OnOutOfMemoryError=dir
-XX:OnOutOfMemoryError=string
Sets a custom command or a series of semicolon-separated commands to run when an OutOfMemoryError exception is first thrown. If the string contains spaces, then it must be enclosed in quotation marks. For an example of a command string, see the description of the -XX:OnError option.
错误时触发脚本
- 作用
- 设置一个自定义命令或一系列以分号分隔的命令，以便在发生不可恢复的错误时运行。如果字符串包含空格，则必须用引号将其括起来。
- 参数
- -XX:OnError=string ```basic -XX:OnError=string Sets a custom command or a series of semicolon-separated commands to run when an irrecoverable error occurs. If the string contains spaces, then it must be enclosed in quotation marks.
The following example shows how the -XX:OnError option can be used to run the gcore command to create the core image, and the debugger is started to attach to the process in case of an irrecoverable error (the %p designates the current process):
-XX:OnError=”gcore %p;dbx - %p”
<a name="H5I5x"></a>
##
<a name="tRCEB"></a>
## Hotspot日志路径
- 作用
- 设置写入日志数据的路径和文件名。默认情况下，该文件创建在当前工作目录中，并命名为 hotspot.log。
- 参数
- -XX:LogFile=path
```basic
-XX:LogFile=path
Sets the path and file name where log data is written. By default, the file is created in the current working directory, and it is named hotspot.log.
The following example shows how to set the log file to /var/log/java/hotspot.log:
-XX:LogFile=/var/log/java/hotspot.log
类型和对象跟踪
对常量池分辨率的跟踪
- 作用
- 启用对常量池分辨率的跟踪。默认情况下，此选项处于禁用状态，并且不会跟踪常量池解析。
参数
作用
- 启用按引用顺序跟踪所有加载的类。默认情况下，此选项处于禁用状态并且不跟踪类。
参数
- -XX:+TraceClassLoadingPreorder
-XX:+TraceClassLoadingPreorder Enables tracing of all loaded classes in the order in which they are referenced. By default, this option is disabled and classes are not traced.
- -XX:+TraceClassLoadingPreorder

- -XX:+PrintConcurrentLocks
设置此选项相当于运行 jstack -l 命令或 jcmd pid Thread.print -l 命令，其中 pid 是当前 Java 进程标识符。
-XX:+PrintConcurrentLocks
Enables printing of java.util.concurrent locks after a Control+C event (SIGTERM). By default, this option is disabled.
Setting this option is equivalent to running the jstack -l command or the jcmd pid Thread.print -l command, where pid is the current Java process identifier.
-XX:+PrintAdaptiveSizePolicy
Enables printing of information about adaptive generation sizing. By default, this option is disabled.
