jProfiler 不提供方法级别的统计信息

Question

我已经在我的 Linux 机器上安装了jProfiler，并将数据保存到 .jps 文件中。然后我将此文件加载到我本地机器上的jProfiler UI 中。

这是我的配置文件：

<?xml version="1.0" encoding="UTF-8"?>
<config>
  <nextId id="104" />
  <generalSettings setupHasRun="false">
    <recordingProfiles>
      <recordingProfile  id="10" name="CPU recording">
            <actionKey id="cpu"/>
      </recordingProfile>
    </recordingProfiles>
  </generalSettings>
  <templates>
    <template id="50" name="Instrumentation, all features supported" startFrozen="false" recordCPUOnStartup="false" vmCannotExit="false" instrumentationType="1" samplingNoFilters="false" lineNumbers="false" samplingFrequency="5" timeType="1" disableCPUProfiling="false" recordAllocOnStartup="true" recordArrayAlloc="true" enableTriggersOnStartup="true" allocTreeRecordingType="1" disableMonitorContentions="false" componentDetection="true" chronoHeap="false" autoUpdatePeriodLong="5" autoUpdatePeriodShort="2" allUrls="false" payloadCap="50" eventCap="20000" showSystemThreads="false" utilConcurrentHandling="true" libraryDebugParameters="" exceptionalCap="5" exceptionalTimeType="4" autoTuneInstrumentation="true" autoTuneMaxAverage="100" autoTuneMinPerMille="10" samplingPayloadCallStacks="true" description="This is JProfiler's fully featured mode. In this setting, call stack information is accurate, but CPU overhead and distortion of measured call times may be high, depending on your filter settings. You should define inclusive filters for your own packages." system="true" />
    <template id="51" name="Sampling for CPU profiling, some features not supported" startFrozen="false" recordCPUOnStartup="false" vmCannotExit="false" instrumentationType="3" samplingNoFilters="false" lineNumbers="false" samplingFrequency="5" timeType="1" disableCPUProfiling="false" recordAllocOnStartup="true" recordArrayAlloc="true" enableTriggersOnStartup="true" allocTreeRecordingType="1" disableMonitorContentions="false" componentDetection="true" chronoHeap="false" autoUpdatePeriodLong="5" autoUpdatePeriodShort="2" allUrls="false" payloadCap="50" eventCap="20000" showSystemThreads="false" utilConcurrentHandling="true" libraryDebugParameters="" exceptionalCap="5" exceptionalTimeType="4" autoTuneInstrumentation="true" autoTuneMaxAverage="100" autoTuneMinPerMille="10" samplingPayloadCallStacks="true" description="This template is particularly suitable for CPU profiling and for memory profiling when accurate allocation information is not important. Sampling has a very low overhead and does not distort measured call tines. Some views, like the method statistics are no available. JEE payloads cannot be annotated in the call tree, but payload hotspots without backtraces are available." system="true" />
  </templates>
  <sessions>
    <session id="80" templateId="50" name="Animated Bezier Curve Demo" type="1" isStartupWorkingDirectory="true" mainClass="bezier.BezierAnim">
      <filters>
        <filter type="inclusive" name="com." />
      </filters>
      <exceptionalMethods/>
      <classPath>
        <classPathEntry path="demo/bezier/classes" />
      </classPath>
      <sourcePath>
        <sourcePathEntry path="demo/bezier/src" />
      </sourcePath>
      <probes>
        <probe name="com.jprofiler.agent.probe.interceptor.TrackingInterceptor" enabled="true" startProbeRecording="false" events="false" annotatePayloads="false">
          <id value="3" />
        </probe>
      </probes>
    </session>

我面临的问题是我无法在jProfiler UI 的 CPU 视图选项卡下获得有关方法统计信息的任何详细信息。

但我可以获取 Telemetrics 中的其他字段。

使用的版本：JProfiler 9.1，我使用示例 config.xml 开始我的测试。我是否需要在我的配置文件中进行任何更改以在我的 .jps 文件中获取方法级别的统计信息

Answer 1

单独记录方法统计信息，因为开销太高，无法始终与 CPU 数据一起记录。

会话进行时，进入方法统计视图并启用记录。对于离线分析，有一个启动方法统计记录的触发操作。
