logback.xml的perf4j设置
大家好，我想知道在使用perf4j时logback.xml的确切配置设置。 我在logback.xml中创建此配置
firstBlock,secondBlock <!-- The NotificationThresholds param configures the sending of JMX notifications when statistic values exceed specified thresholds. This config states that the firstBlock max value should be between 0 and 800ms, and the secondBlock max value should be less than 1500 ms. You can also set thresholds on the Min, Mean, StdDev, Count and TPS statistics - eg firstBlockMean(<600). firstBlockMax(0-800),secondBlockMax(<1500)--> logs/perf4j.log %date %-5level [%thread] %logger{36} [%file:%line] %msg%n logs/perf4j.%d{yyyy-MM-dd}.log 我从perf4j logback文档中得到了它。 因此，当我尝试使用此logback conf时，它不会通过任何exception，但它会打印一些奇怪的语句，如下所示

错误消息非常具有描述性：
18：26：20,462 | -ERROR in ch.qos.logback.core.joran.action.AppenderRefAction – 找不到名为[ graphExecutionTimes ]的appender。 你在配置文件中定义了下面的内容吗？
[…]
18：26：20,506 | -INFO in ch.qos.logback.core.joran.action.AppenderAction – 将appender命名为[ graphExecutionTimes ]
错误消息明确询问您：您是否在配置文件中定义了下面的[graphExecutionTimes] appender？ 事实上，就是这种情况，如上所示。 只需切换这些声明：
以防万一将perf4jFileAppender移到顶部。 如果此代码段来自Perf4J文档，您应该要求作者修复它。
