Настройка системного журнала#

Для логирования событий DataGrid поддерживает следующие библиотеки и фреймворки:

  • JUL (используется по умолчанию);

  • Log4j2;

  • JCL;

  • SLF4J.

При запуске узла он выводит в консоль начальную информацию, в том числе информацию о сконфигурированной библиотеке логирования. Каждая библиотека логирования имеет собственные параметры конфигурации и должна настраиваться согласно официальной документации этой библиотеки. Помимо собственных параметров конфигурации каждой отдельной библиотеки существуют следующие параметры, которые позволяют дополнительно настроить логирование:

Системное свойство

Описание

Значение по умолчанию

IGNITE_LOG_INSTANCE_NAME

Если данное свойство имеет значение set, DataGrid включает в логи название своего экземпляра

Не задано

IGNITE_QUIET

При значении false отключает «тихий» и включает расширенный (verbose) режим. В режиме verbose узел записывает в логи больше информации

true

IGNITE_LOG_DIR

Директория для записи log-файлов DataGrid

$IGNITE_HOME/ work/log

IGNITE_DUMP_THREADS_ON_FAILURE

При значении true данное свойство выдает в логах дампы потоков при появлении критической ошибки

true

IGNITE_SENSITIVE_DATA_LOGGING

  • plain (true) — выводит данные «как есть»;

  • hash — выводит хеш (примитивы выводятся «как есть»);

  • none — (false) не выводит ничего

hash

Логирование по умолчанию (JUL)#

По умолчанию DataGrid использует фреймворк java.util.logging (JUL). Если DataGrid запускается с использованием скрипта ignite.sh|bat из дистрибутива, то по умолчанию в качестве файла конфигурации используется $IGNITE_HOME/config/java.util.logging.properties, выдающий все сообщения в log-файлах в директории $IGNITE_HOME/work/log. Директория, используемая по умолчанию, может быть изменена при помощи системного свойства IGNITE_LOG_DIR.

При использовании DataGrid в приложении в качестве библиотеки, конфигурация логирования, используемая по умолчанию, включает в себя только обработчик консоли на уровне INFO. Собственный файл конфигурации можно использовать, изменив системное свойство java.util.logging.config.file.

Log4j2#

Внимание

Чтобы использовать Log4j2, необходимо подключить модуль ignite-log4j2.

Для включения Log4j2 сконфигурируйте свойство gridLogger класса IgniteConfiguration:

<bean class="org.apache.ignite.configuration.IgniteConfiguration" id="ignite.cfg">
    <property name="gridLogger">
        <bean class="org.apache.ignite.logger.log4j2.Log4J2Logger">
            <!-- Конфигурационный файл log4j2. -->
            <constructor-arg type="java.lang.String" value="ignite-log4j2.xml"/>
        </bean>
    </property>

    <!-- Прочие свойства. -->

</bean>

IgniteConfiguration cfg = new IgniteConfiguration();

IgniteLogger log = new Log4J2Logger("ignite-log4j2.xml");

cfg.setGridLogger(log);

// Запустите узел.
try (Ignite ignite = Ignition.start(cfg)) {
    ignite.log().info("Info Message Logged!");
}

где ignite-log4j2.xml — конфигурационный файл логера log4j2 (смотри пример файла).

Путь к ignite-log4j2.xml может быть как абсолютным, так и локальным относительным путем к META-INF в classpath или к IGNITE_HOME. Пример файла конфигурации log4j2 можно найти в дистрибутиве ($IGNITE_HOME/config/ignite-log4j2.xml).

Примечание

Настройку уровней логирования и других параметров логирования производит администратор ОС или DevOps-инженер.

Настройка уровней логирования#

Уровни логирования настраиваются в конфигурационном файле логера ignite-log4j2.xml в блоке <Loggers>.

Фрагмент конфигурационного файла логера с уровнями логирования:

XML#
<Loggers>
    <Logger name="org.eclipse.jetty.util.log" level="ERROR"/>
    <Logger name="org.eclipse.jetty.util.component" level="ERROR"/>
    <Logger name="com.amazonaws" level="WARN"/>
    <Logger name="org.apache.ignite" level="INFO" additivity="false">
            <appender-ref ref="IGNITE"/>
    </Logger>
    ...
    <Logger name="com.sbt.ignite" level="INFO" additivity="false">
        <AppenderRef ref="IGNITE"/>
    </Logger>
    ...
    </Loggers>

где

  • org.eclipse.jetty.util.log, org.eclipse.jetty.util.component, com.amazonaws, org.apache.ignite – классы, для которых будут генерироваться события;

  • INFO, WARN, ERROR — уровни логирования событий.

Настройка пути для хранения системного журнала (log-файла)#

Путь к log-файлу указывается в конфигурационном файле логера в формате:

XML#
<Routing name="IGNITE">
    <Routes pattern="$${sys:nodeId}">
        <Route>
            <RollingFile name="Rolling-${sys:nodeId}" fileName="/opt/ignite/server/logs/${sys:appId}.log" filePattern="/opt/ignite/server/logs/${sys:appId}-${sys:nodeId}-%i-%d{yyyy-MM-dd}.log.gz">
                <PatternLayout pattern="%d{yyyy-MM-dd HH:mm:ss.SSS} [%-5level][%t][%logger{36}] %msg%n"/>
                <Policies>
                    <TimeBasedTriggeringPolicy interval="1" modulate="true" />
                </Policies>
            </RollingFile>
        </Route>
    </Routes>
</Routing>

где fileName — путь к log-файлу.

Примечание

Log4j2 поддерживает изменение конфигурации в ходе работы. Таким образом, изменения в файле конфигурации применяются без необходимости перезапуска приложения.

Подробную информацию по логеру log4j2 — см. офицальную документацию log4j.

JCL#

Внимание

Чтобы использовать JCL, необходимо подключить модуль ignite-jcl.

JCL лишь пересылает log-сообщения в соответствующую систему логирования, которую нужно предварительно настроить должным образом. Например, для использования Log4j2 убедитесь, что необходимые библиотеки добавлены в свой classpath.

Более подробная информация приведена в официальной документации JCL.

Для включения JCL сконфигурируйте свойство gridLogger класса IgniteConfiguration:

<bean class="org.apache.ignite.configuration.IgniteConfiguration" id="ignite.cfg">
    <property name="gridLogger">
        <bean class="org.apache.ignite.logger.jcl.JclLogger">
        </bean>
    </property>

    <!-- Прочие свойства. -->

</bean>

IgniteConfiguration cfg = new IgniteConfiguration();

cfg.setGridLogger(new JclLogger());

// Запустите узел.
try (Ignite ignite = Ignition.start(cfg)) {
    ignite.log().info("Info Message Logged!");
}

SLF4J#

Внимание

Чтобы использовать SLF4J, необходимо подключить модуль ignite-slf4j.

Для включения SLF4J сконфигурируйте свойство gridLogger класса IgniteConfiguration:

<bean class="org.apache.ignite.configuration.IgniteConfiguration" id="ignite.cfg">
    <property name="gridLogger">
        <bean class="org.apache.ignite.logger.slf4j.Slf4jLogger">
        </bean>
    </property>

    <!-- Прочие свойства. -->

</bean>

IgniteConfiguration cfg = new IgniteConfiguration();

cfg.setGridLogger(new Slf4jLogger());

// Запустите узел.
try (Ignite ignite = Ignition.start(cfg)) {
    ignite.log().info("Info Message Logged!");
}

Более подробная информация приведена в официальной документации SLF4J.

Скрытие конфиденциальной информации в log-файлах#

В log-файлах может отражаться содержание кеш-записей, системных свойств, настроек запуска и прочая информация, которая в некоторых случаях может быть конфиденциальной. Отображение такой информации в log-файлах можно отключить, установив значение системного свойства IGNITE_TO_STRING_INCLUDE_SENSITIVE = false.

Пример команды

./ignite.sh -J-DIGNITE_TO_STRING_INCLUDE_SENSITIVE=false`

Более подробная информация приведена в официальной документации Apache Ignite.

Пример конфигурации логирования#

Для конфигурации логирования:

  1. Включите Log4j2, как описано в разделе Log4j2.

  2. При использовании стандартного файла конфигурации (ignite-log4j2.xml) раскомментируйте appender CONSOLE.

  3. В файле конфигурации log4j2 укажите путь к log-файлу. По умолчанию log-файлы сохраняются в директорию ${IGNITE_HOME}/work/log/ignite.log.

  4. Запустите узлы в verbose-режиме:

    • при использовании утилиты ignite.sh для запуска узлов — добавьте ключ -v;

    • если запуск узлов производится из Java-кода — используйте системную переменную IGNITE_QUIET=false.
