java - 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，我正在将数据保存到 .jps 文件中。然后，我将此文件加载到我本地计算机的 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 views 选项卡下获得有关方法统计信息的任何详细信息。

但我能够获取 Telemetrics 中的其他字段。

正在使用的版本: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才能在我的 .jps 文件中获取方法级统计信息

Answer 1

方法统计单独记录，因为开销太大，总是和CPU数据一起记录。

当 session 处于实时状态时，转到方法统计 View 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。
