JMeter：重置计数值

我正在对数据库的CRUD调用执行基本的API测试 . 在JMeter中，我的测试计划中有1个线程和3个线程组，我在每个线程中设置了循环和计数器 . 计数器的原因是将结果保存到文件时，我想用计数器值附加文件的前缀 .

问题是计数器永远不会重置 . 例如：

Where Count = 1 for all groups, I would expect: 
Thread Group 1, filename_1.json
Thread Group 2, filename_2.json
Thread Group 3, filename_3.xml

Where Group 1 Count = 3, Group 2 Count = 2, Group 3 Count = 1, I would expect: 
Thread Group 1, filename_1.json, filename_2.json, filename_3.json
Thread Group 2, filename_4.json and filename_5.json
Thread Group 3, filename_6.xml

相反，对于所有组，Count = 1，我得到的结果如下：

Thread Group 1, filename_11.json
Thread Group 2, filename_14.json
Thread Group 3, filename_18.xml

经过多次搜索并尝试了多个建议后，我仍然没有得到我的期望 . 以下是如何配置测试计划的示例 .

任何建议都非常感谢 .

Thread Group 1
    HTTP Header Manager (application/json)
     Loop Controller
       Counter (Start=1, Increment=1, Maximum=100, Num Format=null, Ref Name=LoopCounter1)
       HTTP Request (CREATE)
         RegEx (RefName=newRequest, Reg Ex = "id":(.+?)\,"displayName", Template=$1$, Match No.=1, Default=NONE)
          BeanShell Assertion (Name=newRequest, Param=${__setProperty(newRequest,${newRequest},)})
          Save Response to file (File prefix=requestResult_${LoopCounter}, Var Name=newRequestFile)
       Loop Controller
          HTTP Request (READ)
          HTTP Request (UPDATE)
          HTTP Request (DELETE)

Thread Group 2
    HTTP Header Manager (application/json)
     Loop Controller
       Counter (Start=1, Increment=1, Maximum=100, Num Format=null, Ref Name=LoopCounter2)
       HTTP Request (CREATE)
          RegEx (RefName=newContractId, Reg Ex = "id":(.+?)\,"terminationType", Template=$1$, Match No.=1, Default=NONE)
          BeanShell Assertion (Name=newContractId, Param=${__setProperty(newContractId,${newContractId},)})
          Save Response to file (File prefix=contractRecords_${LoopCounter2}, Var Name=newContractFile)
       Loop Controller
          HTTP Request (READ)
          HTTP Request (UPDATE)
          HTTP Request (DELETE)

Thread Group 3
    HTTP Header Manager (application/xml)
     Loop Controller
       Counter (Start=1, Increment=1, Maximum=100, Num Format=null, Ref Name=LoopCounter3)
       HTTP Request (CREATE)
          RegEx (RefName=newPricingId, Reg Ex = "id":(.+?)\,"terminationType", Template=$1$, Match No.=1, Default=NONE)
          BeanShell Assertion (Name=newPricingId, Param=${__setProperty(newPricingId,${newPricingId},)})
          Save Response to file (File prefix=pricingRecords_${LoopCounter3}, Var Name=newPricingFile)
       Loop Controller
          HTTP Request (READ)
          HTTP Request (UPDATE)
          HTTP Request (DELETE)

UPDATE

我更接近预期的结果 . 启用“每个线程组上的重置计数器”后，我希望线程组2的计数重置为0.但是，它继续从前一个线程开始 . 我需要重置每个线程组中的计数器 . 原因如下：

Thread Group 2
   HTTP Header Manager (application/json)
   Loop Controller
      Counter (Start=1, Increment=1, Maximum=100, Num Format=null, Ref Name=LoopCounter2)
      HTTP POST Request (CREATE)
        ${__FileToString(${payloadArchive}/${__eval(contract_${LoopCounter})}.json,,)}

正如您所看到的，我使用Thread Group 2的每个循环将不同的文件传递到HTTP Request的主体中 . 每个.json文件都包含基于数据库的唯一约束的唯一元素 . 这些文件名为“contract_01.json”，“contract_02.json”，“contract_03.json”等 . 这就是我希望Thread Group 2重新启动它的计数器的原因 .
