大家好，我想知道 logback.xml 与 perf4j 一起使用时的确切配置设置。我在 logback.xml 中创建了这个配置
<configuration>
<!-- Perf4J appenders -->
<!--
This AsyncCoalescingStatisticsAppender groups StopWatch log messages
into GroupedTimingStatistics messages which it sends on the
file appender defined below
-->
<appender name="CoalescingStatistics" class="org.perf4j.logback.AsyncCoalescingStatisticsAppender">
<param name="TimeSlice" value="60000"/>
<appender-ref ref="graphExecutionTimes"/>
<appender-ref ref="graphExecutionTPS"/>
<!-- We add the JMX Appender reference onto the CoalescingStatistics -->
<appender-ref ref="perf4jJmxAppender"/>
</appender>
<appender name="graphExecutionTimes" class="org.perf4j.logback.GraphingStatisticsAppender">
<!-- Possible GraphTypes are Mean, Min, Max, StdDev, Count and TPS -->
<param name="GraphType" value="Mean"/>
<!-- The tags of the timed execution blocks to graph are specified here -->
<param name="TagNamesToGraph" value="DESTROY_TICKET_GRANTING_TICKET,GRANT_SERVICE_TICKET,GRANT_PROXY_GRANTING_TICKET,VALIDATE_SERVICE_TICKET,CREATE_TICKET_GRANTING_TICKET" />
</appender>
<appender name="graphExecutionTPS" class="org.perf4j.logback.GraphingStatisticsAppender">
<param name="GraphType" value="TPS" />
<param name="TagNamesToGraph" value="DESTROY_TICKET_GRANTING_TICKET,GRANT_SERVICE_TICKET,GRANT_PROXY_GRANTING_TICKET,VALIDATE_SERVICE_TICKET,CREATE_TICKET_GRANTING_TICKET" />
</appender>
<!--
This JMX appender creates an MBean and publishes it to the platform MBean server by
default.
-->
<appender name="perf4jJmxAppender" class="org.perf4j.logback.JmxAttributeStatisticsAppender">
<!--
You must specify the tag names whose statistics should be exposed as
MBean attributes.
-->
<TagNamesToExpose>firstBlock,secondBlock</TagNamesToExpose>
<!--
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 - e.g. firstBlockMean(<600).
<NotificationThresholds>firstBlockMax(0-800),secondBlockMax(<1500)</NotificationThresholds>-->
<!--
You can also specify an optional MBeanName param, which overrides
the default MBean name of org.perf4j:type=StatisticsExposingMBean,name=Perf4J
-->
</appender>
<!-- Loggers -->
<!--
The Perf4J logger. Note that org.perf4j.TimingLogger is the value of the
org.perf4j.StopWatch.DEFAULT_LOGGER_NAME constant. Also, note that
additivity is set to false, which is usually what is desired - this means
that timing statements will only be sent to this logger and NOT to
upstream loggers.
-->
<logger name="org.perf4j.TimingLogger" additivity="false">
<level value="INFO"/>
<appender-ref ref="CoalescingStatistics"/>
<appender-ref ref="perf4jFileAppender"/>
</logger>
<!-- This file appender is used to output aggregated performance statistics -->
<appender name="perf4jFileAppender" class="ch.qos.logback.core.rolling.RollingFileAppender">
<File>logs/perf4j.log</File>
<encoder>
<Pattern>%date %-5level [%thread] %logger{36} [%file:%line] %msg%n</Pattern>
</encoder>
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<FileNamePattern>logs/perf4j.%d{yyyy-MM-dd}.log</FileNamePattern>
</rollingPolicy>
</appender>
</configuration>
我从 perf4j logback 文档中得到它。因此，当我尝试使用此 logback conf 时，它没有出现任何异常，但它会打印出一些奇怪的语句，如下所示
