I am running a load test using JMeter and I want take the ConstantThroughputTimer value as user input and set in the JMX XML. The JMeter shell script is being called from a bash script.
Bash Script:
THROUGHPUT_VALUE=121
THROUGHPUT_VALUE=$(echo "$THROUGHPUT_VALUE" | awk '{printf "%.1f", $1}')
$JMETER_INSTALL_DIR/jmeter.sh -n -t $JMETER_LOAD_PROFILE_CONFIG/$PROFILE_FILE_NAME -JThroughput=$THROUGHPUT_VALUE
JMeter JMX XML (This is not complete XML. Just a snippet of the full XML where user defined variable and Throughput time is declared)
<UserParameters guiclass="UserParametersGui" testclass="UserParameters" testname="User Parameters" enabled="true">
<collectionProp name="UserParameters.names">
<stringProp name="904465283">CurrentDay</stringProp>
<stringProp name="-2026347353">CurrentDate</stringProp>
<stringProp name="-2025863226">CurrentTime</stringProp>
<stringProp name="690807817">FinalDate_Header1</stringProp>
<stringProp name="-323914198">throughput</stringProp>

<stringProp name="1821498968">${__time(HH:mm:ss)}</stringProp>
<stringProp name="52928079">${__time(E\, dd MMM yyyy\, h:mm:ss,)} +0000</stringProp>
<stringProp name="1446819321">${__P(Throughput)}</stringProp>
</collectionProp></collectionProp> </UserParameters>
<ConstantThroughputTimer guiclass="TestBeanGUI" testclass="ConstantThroughputTimer" testname="Constant Throughput Timer" enabled="true">
<intProp name="calcMode">0</intProp>
<doubleProp>
<name>throughput</name>
<value>${__P(Throughput)}</value>
<savedValue>0.0</savedValue>
</doubleProp>
</ConstantThroughputTimer>
But JMeter is throwing error
Error in NonGUIDriver java.lang.IllegalArgumentException: Problem loading XML from:'/mnt/Test.jmx'.

I even changed the property of the XML from
<stringProp name="-323914198">${__P(Throughput)}</stringProp> to <doubleProp name="-323914198">${__P(Throughput)}</doubleProp>
thinking that it's a float or double value. But still getting same error. Is there any way I can resolve this?

- Btw.: Your shown XML file is no valid XML file. – Cyrus Commented Mar 6 at 22:38
- I haven't shared the complete XML. It's just snippet of the user parameters and constant throughput timer. Why do you think it's not valid? If I remove <value>${__P(Throughput)}</value> and put a double number then it's working fine. So XML is valid. – Suvendu Mandal Commented Mar 7 at 5:03

Reset to default 1It's better to use JMeter GUI for creating and editing test plans:
This results in the following XML configuration:
<ConstantThroughputTimer guiclass="TestBeanGUI" testclass="ConstantThroughputTimer" testname="Constant Throughput Timer">
<intProp name="calcMode">0</intProp>
<stringProp name="throughput">${__P(Throughput,)}</stringProp>
</ConstantThroughputTimer>
Once done you can set the property value via -J command-line argument like:
jmeter -JThroughput=12345 -n -t test.jmx -l result.jtl
