常量计时器不能与命令行中的jmeter一起工作

我有一个jmeter测试，其中有常数定时器与WebSocket请求连接，但是当我用jmeter启动测试时，使用命令行，jmeter不处理定时器

<eu.luminis.jmeter.wssampler.SingleWriteWebSocketSampler enabled="true" guiclass="eu.luminis.jmeter.wssampler.SingleWriteWebSocketSamplerGui" testclass="eu.luminis.jmeter.wssampler.SingleWriteWebSocketSampler" testname="WebSocket Single Write Sampler">
              <boolProp name="TLS">false</boolProp>
              <stringProp name="server" />
              <stringProp name="port">80</stringProp>
              <stringProp name="path" />
              <boolProp name="binaryPayload">true</boolProp>
              <stringProp name="requestData">00 00 00 00 20 18 00 01 00 ff 00 ff 00 ff 10 08 00 00 00 00</stringProp>
              <boolProp name="createNewConnection">false</boolProp>
              <boolProp name="optional">false</boolProp>
            </eu.luminis.jmeter.wssampler.SingleWriteWebSocketSampler>
            <hashTree>
        <ConstantTimer enabled="true" guiclass="ConstantTimerGui" testclass="ConstantTimer" testname="Constant Timer">
                <stringProp name="ConstantTimer.delay">60000.0</stringProp>
              </ConstantTimer>
              <hashTree />
              <ConstantTimer enabled="true" guiclass="ConstantTimerGui" testclass="ConstantTimer" testname="Constant Timer">
                <stringProp name="ConstantTimer.delay">60008.427676</stringProp>
              </ConstantTimer>
              <hashTree />
            </hashTree>

但是当我把常量计时器放在WebSocket采样器上面时（这将影响每一个websocket采样器，而不仅仅是这个），jmeter会照顾计时器
结果如下所示

summary +      1 in 00:00:31 =    0.0/s Avg:  3259 Min:  3259 Max:  3259 Err:     0 (0.00%) Active: 1 Started: 1 Finished: 0
summary +  11445 in 00:00:07 = 1618.1/s Avg:     0 Min:     0 Max:   567 Err: 10953 (95.70%) Active: 0 Started: 1 Finished: 1
summary =  11446 in 00:00:38 =  304.2/s Avg:     0 Min:     0 Max:  3259 Err: 10953 (95.69%)

但是我有几个计时器，一个是60秒（就像上面的那个）

jmeter

按热度按时间

JMeter计时器遵循JMeter scoping rules，因此如果您希望Constant Timer仅应用于一个特定的采样器，则需要将其作为采样器的子

此外，查看常量定时器源代码，您似乎需要提供Long值，因此相应地将这些60000.0和60008.427676更改为60000和60008。
每60秒创建1个请求的测试计划示例：

您还可以考虑使用流控制操作采样器来引入暂停，作为常量计时器的替代方法
