0 序言
- 工欲善其事，必先利其器。最近遇到一个生产环境的极难排查的问题，已经消耗了近一段时间的较多心力了，故今日稳固和新学习一下JVM相关的诊断工具，以便于磨刀霍霍向"
BUG"
1 jcmd 概述
1.1 jcmd 简述
- jcmd 是在 JDK1.7 以后，新增了一个命令行工具。
- 即 支持的最低版本： JDK1.7
- jcmd 是一个多功能的工具，相比 jstat 功能更为全面的工具，可用于获取目标 Java 进程的性能统计、JFR、内存使用、垃圾收集、线程堆栈、JVM 运行时间，也可以手动执行 GC、导出线程信息、导出堆信息等信息。
1.2 版本兼容问题
- 在 JDK 1.8.0_73中不支持 GC.heap_info 参数
以 JDK 1.8.0_261 示范：
C:\Users\{USER}\Desktop>jcmd 17124 GC.heap_info

2 jcmd 用法
2.1 help
jcmd help
C:\Users\{USER}\Desktop>jcmd help
Error parsing arguments: No command specified
Usage: jcmd <pid | main class> <command ...|PerfCounter.print|-f file>
or: jcmd -l
or: jcmd -h
command must be a valid jcmd command for the selected jvm.
Use the command "help" to see which commands are available.
If the pid is 0, commands will be sent to all Java processes.
The main class argument will be used to match (either partially
or fully) the class used to start Java.
If no options are given, lists Java processes (same as -p).
PerfCounter.print display the counters exposed by this process
-f read and execute commands from the file
-l list JVM processes on the local machine
-h this help
jcmd {PID} help
命令：
jcmd <pid> help
作用：列出当前运行的 java 进程可以执行的操作
说明：不同的 jvm 进程 支持的操作可能是不一样的
# jcmd 17124 help
17124:
The following commands are available:
JFR.stop
JFR.start
JFR.dump
JFR.check
VM.native_memory
VM.check_commercial_features
VM.unlock_commercial_features
ManagementAgent.stop
ManagementAgent.start_local
ManagementAgent.start
VM.classloader_stats
GC.rotate_log
Thread.print
GC.class_stats
GC.class_histogram
GC.heap_dump
GC.finalizer_info
GC.heap_info
GC.run_finalization
GC.run
VM.uptime
VM.dynlibs
VM.flags
VM.system_properties
VM.command_line

help
For more information about a specific command use 'help <command>'.
参数描述
-
pid：[常用] 接收诊断命令请求的进程ID。
-
main class ：**[不常用] **接收诊断命令请求的进程的main类。匹配进程时，main类名称中包含指定子字符串的任何进程均是匹配的。
如果多个正在运行的Java进程共享同一个main类，诊断命令请求将会发送到所有的这些进程中。
-
command：[常用] 支持的子命令，示例：GC.class_stats、GC.class_histogram。
注意: 如果任何参数含有空格，你必须使用英文的单引号或双引号将其包围起来。 此外，你必须使用转义字符来转移参数中的单引号或双引号，以阻止操作系统shell处理这些引用标记。当然，你也可以在参数两侧加上单引号，然后在参数内使用双引号(或者，在参数两侧加上双引号，在参数中使用单引号)。
-
Perfcounter.print：[不常用] 打印目标Java进程上可用的性能计数器。性能计数器的列表可能会随着Java进程的不同而产生变化。
-
-f file：[不常用] 从文件file中读取命令，然后在目标Java进程上调用这些命令。在file中，每个命令必须写在单独的一行。以"#"开头的行会被忽略。当所有行的命令被调用完毕后，或者读取到含有stop关键字的命令，将会终止对file的处理。
-
-l：[常用] 查看所有的进程列表信息。
-
-h：[常用] 查看帮助信息。（同 -help）
2.2 查看具体命令的参数/help
命令：jcmd <pid> help command
作用：列出当前运行的 java 进程可以执行的操作
说明：不同的 jvm 进程 支持的操作可能是不一样的
示例：
# jcmd 20399 help GC.class_stats
20399:
GC.class_stats
Provide statistics about Java class meta data. Requires -XX:+UnlockDiagnosticVMOptions.
Impact: High: Depends on Java heap size and content.
Syntax : GC.class_stats [options] [<columns>]
Arguments:
columns : [optional] Comma-separated list of all the columns to show. If not specified, the following columns are shown: InstBytes,KlassBytes,CpAll,annotations,MethodCount,Bytecodes,MethodAll,ROAll,RWAll,Total (STRING, no default value)
Options: (options must be specified using the <key> or <key>=<value> syntax)
-all : [optional] Show all columns (BOOLEAN, false)
-csv : [optional] Print in CSV (comma-separated values) format for spreadsheets (BOOLEAN, false)
-help : [optional] Show meaning of all the columns (BOOLEAN, false)
2.3 查看进程/-l
命令: jcmd -l
作用：查看 当前机器上所有的 jvm 进程信息。
同类作用的命令：jcmd、 jcmd -l 、 jps -lm 这三个命令作用相同
示例:

2.4 查看内存信息/GC.heap_info
命令：jcmd <pid> GC.heap_info
作用：查看JVM内存信息，虽然名称为heap_info，但是除了堆内存信息，也会有堆外内存之一的Metaspace的信息。相比jstat命令结果会更直观一些。
jcmd 17124 GC.heap_info

2.6 查看已启动时长/VM.uptime
命令：jcmd <pid> VM.uptime
作用：查看 JVM 的已启动时长。
示例：
# jcmd 17124 VM.uptime
17124:
16096.667 s
2.7 查看系统中【类】的统计信息/GC.class_histogram
命令：jcmd <pid> GC.class_histogram
作用：查看系统中类统计信息。
同类作用的命令：和jmap -histo pid的效果是一样的，可以查看每个类的实例数量和占用空间大小。
示例：
# jcmd 17124 GC.class_histogram > class_histogram.txt
17124:
num #instances #bytes class name

2.9 导出内存Dump文件/GC.heap_dump
命令：jcmd <pid> GC.heap_dump FILE_NAME
作用：查看 JVM 的Heap Dump。导出的 dump 文件，可以使用MAT 或者 Visual VM 等工具进行分析（如果只指定文件名，默认会生成在启动 JVM 的目录里）
同类作用的命令：和 jmap -dump:format=b,file=heapdump.phrof pid 作用一样
示例：
# jcmd 17124 GC.heap_dump ./dump.hprof
17124: Heap dump file created
2.10 查看JVM系统属性/VM.system_properties
命令：jcmd <pid> VM.system_properties
作用：查看 JVM 的属性信息。
同类作用的命令：和jinfo -sysprops pid作用一样。jinfo pid会输出 VM.system_properties 和 VM.flags，命令短，更好记住，所以推荐直接使用jinfo pid。
示例：
# jcmd 17124 VM.system_properties
17124:

2.11 查看JVM启动参数/VM.flags
命令：jcmd <pid> VM.flags
作用：查看 JVM 的启动参数。
同类作用的命令：和jinfo -flags {pid}作用一样。jinfo pid会输出 VM.system_properties 和 VM.flags。
示例：
# jcmd 17124 VM.flags
17124:
-XX:CICompilerCount=4 -XX:InitialHeapSize=264241152 -XX:MaxHeapSize=4227858432 -XX:MaxNewSize=1409286144 -XX:MinHeapDeltaBytes=524288 -XX:NewSize=88080384 -XX:OldSize=176160768 -XX:+UnlockCommercialFeatures -XX:+UseCompressedClassPointers -XX:+UseCompressedOops -XX:+UseFastUnorderedTimeStamps -XX:-UseLargePagesIndividualAllocation -XX:+UseParallelGC
2.12 查看JVM启动命令行/VM.command_line
命令：jcmd <pid> VM.command_line
作用：查看 JVM 的启动命令行。
示例：
# jcmd 17124 VM.command_line
17124:
VM Arguments:
jvm_args: -Xmx512m
java_command: /etc/java-app/springtest-0.0.1-SNAPSHOT.jar
java_class_path (initial): /etc/java-app/springtest-0.0.1-SNAPSHOT.jar
Launcher Type: SUN_STANDARD
2.13 执行finalization操作/GC.run_finalization
命令：jcmd <pid> GC.run_finalization
作用： 对 JVM 执行 java.lang.System.runFinalization()。即 ：执行一次 finalization 操作
调用已经失去引用的对象的finalize方法，但JVM可以选择执行或者不执行。
示例：
# jcmd 17124 GC.run_finalization
17124:
Command executed successfully
2.14 执行垃圾收集/GC.run
命令：jcmd <pid> GC.run
作用：对 JVM 执行 java.lang.System.gc()。同 GC.run_finalization 告诉垃圾收集器打算进行垃圾收集，但是JVM可以选择执行或者不执行。
$ jcmd 17124 GC.run
17124:
Command executed successfully
2.15 查看JVM进程版本信息/VM.version
命令：jcmd <pid> VM.version
作用：查看目标jvm进程的版本信息。
示例：
# jcmd 6339 VM.version
6339:
OpenJDK 64-Bit Server VM version 25.282-b08
JDK 8.0_282
2.16 VM.native_memory
命令：jcmd <pid> VM.native_memory
作用：查看目标jvm进程的Native Memory Tracking (NMT)信息，用于追踪JVM的内部内存使用。
注意：
- 打开NMT会带来5%-10%的性能损耗。
-XX:NativeMemoryTracking=xx参数必须放在-jar前面- 示例：
java -XX:NativeMemoryTracking=detail -jar -Xmn512m user.jar
- 示例：
- 使用 -XX:NativeMemoryTracking=summary 可以用于开启NMT，其中该值默认为off。
- 可以设置summary、detail来开启；开启的话，大概会增加5%-10%的性能消耗；
- 使用-XX:+UnlockDiagnosticVMOptions -XX:+PrintNMTStatistics。 可以在jvm shutdown的时候输出整体的native memory统计；
- 其他的可以使用jcmd pid VM.native_memory相关命令进行查看、diff、shutdown等
- 整个memory主要包含了Java Heap、Class、Thread、Code、GC、Compiler、Internal、Other、Symbol、Native Memory Tracking、Arena Chunk这几部分；
- 其中 reserved 表示应用可用的内存大小，committed 表示应用正在使用的内存大小
jcmd <pid> VM.native_memory [summary | detail | baseline | summary.diff | detail.diff | shutdown] [scale= KB | MB | GB]
# summary: 分类内存使用情况.
# detail: 详细内存使用情况，除了summary信息之外还包含了虚拟内存使用情况。
# baseline: 创建内存使用快照，方便和后面做对比
# summary.diff: 和上一次baseline的summary对比
# detail.diff: 和上一次baseline的detail对比
# shutdown: 关闭NMT
示例：
# jcmd 17124 VM.native_memory
17124:
Native memory tracking is not enabled
- 查看是否已开启NMT
# jinfo -flag NativeMemoryTracking 17124
-XX:NativeMemoryTracking=off
# jinfo -flag UnlockDiagnosticVMOptions 17124
# jinfo -flag PrintNMTStatistics 17124
- 实时设置开启NMT
# jinfo -flag NativeMemoryTracking=summary/detail 17124
[X] 不支持运行时修改 Exception in thread "main" com.sun.tools.attach.AttachOperationFailedException: flag 'NativeMemoryTracking' cannot be changed
# jinfo -flag +UnlockDiagnosticVMOptions 17124

# jinfo -flag +PrintNMTStatistics 17124
