Question

我一直在关注Kaa提供的教程（谢谢！）和文档。我在java中开发了一个完美运行的kaa-client，它已经部署完毕。但是，它确实非常冗长。它适用于调试和东西，但现在它正在创建一个巨大的日志。有没有办法避免特定类和包的INFO消息 - 比如“ org.kaaproject.kaa.client.channel.impl。* ”

Answer 1

要为kaa日志配置特定级别，您应配置相应的日志架构文件。默认情况下，它是 logback.xml 。例如，对于数据收集演示的Java源，日志架构为： JDataCollectionDemo / res / logback.xml 要避免特定类或包的INFO消息，只需将具有ERROR级别的相应行添加到模式中，例如：

<logger name="org.kaaproject.kaa.client.channel.impl" level="ERROR"/>

在这种情况下，完整的日志架构将是：

    <?xml version="1.0" encoding="UTF-8" ?>

    <configuration>
        <appender name="console" class="ch.qos.logback.core.ConsoleAppender">
            <encoder>
                <pattern>%d{ISO8601} [%thread] %-5level %logger{36} - %msg%n</pattern>

        <root level="INFO">
            <appender-ref ref="console"/>
            <appender-ref ref="fileLogAppender"/>
        </root>

        <logger name="org.kaaproject.kaa" level="ERROR"/>
        <logger name="org.kaaproject.kaa.client.logging.memory" level="INFO"/>
        <logger name="org.kaaproject.kaa.demo.datacollection" level="INFO"/>
        <logger name="org.kaaproject.kaa.client.channel.impl" level="ERROR"/>
    </configuration>

还可以更改Sandbox中日志的日志级别：对于 /var/log/kaa/kaa-node.log 和 /var/log/kaa/kaa-sandbox.log ，相应的日志架构文件为： /usr/lib/kaa-node/conf/logback.xml 和 /usr/lib/kaa-sandbox/conf/logback.xml 在沙箱日志架构配置后，应重新启动相应的服务：

sudo service kaa-node restart
sudo service kaa-sandbox restart
