    Ubuntu install java mission control

    JDK Mission Control (JMC) 8.0 and 8.0.1 starts with Oracle JDK 8 (64-bit), and from JMC 8.1.0 onwards it requires Oracle JDK 11 and later. However, JMC 8 supports Java Management Console (JMX) monitoring and Java Flight Recorder (JFR) profiling of JVMs (JDK 7u40 and later) on any supported platform.

    Prerequisite

    • Ensure you install JDK 8 for JMC 8.0 and JMC 8.0.1, and JDK 11 or later for JMC 8.1.0 onwards. See: JDK 11 Installation Instructions or JDK 8 Installation Instructions as applicable.
    • Ensure that the hsperfdata_username directory is present in the Windows $TEMP directory (for example, C:\Users\user_name\AppData\Local\Temp\hsperfdata_username) and is writable by the user. In case there are any issues while starting JMC with user permissions, then start JMC as an administrator. Also ensure that you are using a file system that supports ACL.
    • For monitoring or recording a 32-bit JVM (JDK 7u40 and later), start the JVM with the following VM argument: -Dcom.sun.management.jmxremote

    JMC Usage Instructions

    Depending on your platform, run the following commands:

     $ tar zxf jmc-_linux-x64.tar.gz $ ./jmc-_linux-x64/JDK\ Mission\ Control/jmc

    For example:

     $ tar zxf jmc-8.3.1_linux-x64.tar.gz $ ./jmc-8.3.1_linux-x64/JDK\ Mission\ Control/jmc 
     $ tar zxf jmc-_macos-x64.tar.gz $ open ./jmc-_macos-x64/JDK\ Mission\ Control.app

    For example:

     $ tar zxf jmc-8.3.1_macos-x64.tar.gz $ open ./jmc-8.3.1_macos-x64/JDK\ Mission\ Control.app 
     $ tar zxf jmc-_macos-aarch64.tar.gz $ open ./jmc-_macos-aarch64/JDK\ Mission\ Control.app

    For example:

     $ tar zxf jmc-8.3.1_macos-aarch64.tar.gz $ open ./jmc-8.3.1_macos-aarch64/JDK\ Mission\ Control.app

    Double-click JDK Mission Control from Finder or drag JDK Mission Control.app to the Applications directory to access from Launchpad.

     jar xvf "jmc-_windows-x64.zip" ".\jmc-_windows-x64\JDK Mission Control\jmc.exe"

    For example:

     jar xvf "jmc-8.3.1_windows-x64.zip" ".\jmc-8.3.1_windows-x64\JDK Mission Control\jmc.exe"

    Double-click jmc.exe from Windows Explorer.

    Specify the JDK Version to be Used by JMC

    If there are multiple JDK versions installed, it is recommended to use the latest version of JDK to run JMC.

    Edit the JMC launch configuration (jmc.ini) file and add the location of the JDK version to use (JDK 8 (64-bit) or later required). In Windows and Linux, the jmc.ini file is found under the JDK Mission Control directory; and in macOS, under JDK\ Mission\ Control.app/Contents/Eclipse directory.

    Add the -vm flag and /bin ( \bin for windows) as shown in the following example. Ensure it is added just before the -vmargs flag.

     -vm C:\Program Files\Java\jdk-11.0.19\bin -vmargs 
     -vm /Library/Java/JavaVirtualMachines/jdk-11.0.19.jdk/Contents/Home/bin -vmargs 
     -vm /usr/java/jdk-11.0.19/bin -vmargs

    Below is a sample of jmc.ini from the Windows platform:

     -startup plugins/org.eclipse.equinox.launcher_1.6.400.v20210924-0641.jar --launcher.library plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.2.500.v20220509-0833 --launcher.appendVmargs -vm C:\Program Files\Java\jdk-11.0.19\bin -vmargs -XX:+IgnoreUnrecognizedVMOptions -XX:+UnlockDiagnosticVMOptions -XX:+DebugNonSafepoints -XX:FlightRecorderOptions=stackdepth=128 -XX:+FlightRecorder -XX:StartFlightRecording=name=JMC_Default,maxsize=100m -Djava.net.preferIPv4Stack=true -Djdk.attach.allowAttachSelf=true --add-exports=java.xml/com.sun.org.apache.xerces.internal.parsers=ALL-UNNAMED --add-exports=jdk.internal.jvmstat/sun.jvmstat.monitor=ALL-UNNAMED --add-exports=java.management/sun.management=ALL-UNNAMED --add-exports=java.management/sun.management.counter.perf=ALL-UNNAMED --add-exports=jdk.management.agent/jdk.internal.agent=ALL-UNNAMED --add-exports=jdk.attach/sun.tools.attach=ALL-UNNAMED --add-opens=java.base/java.net=ALL-UNNAMED --add-opens=jdk.attach/sun.tools.attach=ALL-UNNAMED -Dsun.java.command=JMC --add-exports=java.desktop/sun.awt.windows=ALL-UNNAMED

    Мониторинг рабочих нагрузок Java и управление ими с помощью JDK Flight Recorder и Mission Control

    Из этой статьи вы узнаете, как выполнять мониторинг и администрирование рабочих нагрузок Java с помощью JDK Flight Recorder и JDK Mission Control.

    Она была представлена компанией Oracle в 2018 году и управляется как проект на базе OpenJDK. Flight Recorder и Mission Control вместе предоставляют интерактивные возможности управления и мониторинга с минимальными затратами для рабочих нагрузок Java.

    Установка JDK Mission Control и подключение к виртуальной машине Java

    Выполните приведенные ниже действия, чтобы установить JDK Mission Control, подключиться к виртуальной машине Java (JVM) и получать представление обо всех аспектах запущенного приложения в реальном времени.

    1. Убедитесь в том, что JDK установлен.
    2. Найдите двоичный файл JDK Mission Control в репозитории OpenJDK JMC Project на GitHub. Затем выберите необходимую версию для системы, сохраните ее в локальном расположении и перейдите к этому каталогу.
    3. Разверните скачанный файл. Приведенные ниже примеры предназначены для Azul Zulu Mission Control. Linux: 
    tar -xzvf zmc8.0.0.17-ca-linux_x64.tar.gz 
    unzip -zxvf zmc8.0.0.17-ca-win_x64.zip 
    tar -xzvf zmc8.0.0.17-ca-macos_x64.tar.gz 
    $JAVA_HOME/bin/java -jar MyApplication.jar 
    zmc8.0.0.17-ca-macos_x64/Zulu\ Mission\ Control.app/Contents/MacOS/zmc
    1. На верхней левой панели окна Zulu Mission Control откройте вкладку JVM Browser (Браузер JVM).
    2. Выберите и разверните элемент списка в верхнем левом углу для экземпляра JVM, на котором запущено приложение.

    Expand the list item in the upper left for your JVM instance

    1. Если в окне инструмента отобразится сообщение No Recordings (Нет записей), создайте запись. Чтобы начать запись, щелкните правой кнопкой мыши строку Java Flight Recorder на вкладке браузера JVM и щелкните Start Flight Recording (Начать запись).
    2. Выберите запись с фиксированной продолжительностью или непрерывную запись, а также конфигурацию профилирования (точную) или непрерывную конфигурацию (меньшие общие расходы), а затем нажмите кнопку Finish (Готово).

    Start a Flight Recording

    1. Строка записи, осуществляемой во время выполнения приложения, должна отобразиться под строкой Flight Recorder на вкладке JVM Browser (Браузер JVM). Щелкните правой кнопкой мыши строку с записью, осуществляемой во время выполнения приложения, и выберите Dump whole recording (Создать дамп всей записи).
    2. Отобразится новая вкладка в большой области справа от окна Zulu Mission Control. Эта область представляет запись, осуществляемую во время выполнения приложения, дамп которой создан из JVM, на которой запущено приложение.
    1. Если активация еще не выполнена, откройте вкладку Outline (Структура) в левой области окна Zulu Mission Control. Эта вкладка содержит различные представления данных, собранных в рамках записи, осуществляемой во время выполнения приложения.

    Review the Flight Recording
