如何更改Kaa客户端的日志级别

Question

我一直在关注 Kaa 提供的教程（谢谢！）和文档。我在 java 开发了一个 kaa-client，它运行良好并且已经部署。但是，它确实非常冗长。它对调试和其他东西很有用，但现在它正在创建一个巨大的日志。有没有办法避免针对特定类和包的信息消息——比如“org.kaaproject.kaa.client.channel.impl.*”

Answer 1

要为 kaa 日志配置特定级别，您应该配置适当的 log-schema 文件。默认为 logback.xml。例如，对于 Data Collection Demo 的 Java 来源，日志模式是：JDataCollectionDemo/res/logback.xml 要避免特定类或包的 INFO 消息，只需将具有错误级别的适当行添加到架构中，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>

        <root level="INFO">

            <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>

也可以更改沙盒中日志的日志级别：对于 /var/log/kaa/kaa-node.log 和 /var/log/kaa/kaa-sandbox.log，相应的日志模式文件是：/usr/lib/kaa-node/conf/logback.xml 和 /usr/lib/kaa-sandbox/conf/logback.xml 在沙盒日志模式配置适当的服务后应该重新启动：

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