I am trying to send ISO 8583 Message Request through JMeter and getting
(channel/HOSTNAME:POST) [receive] In: 1210 000001 in JMeter Logs
I have left all the fields empty for Response Validation like Timeout and Success Response Field so that no validation rule is applied on response.
But I am not receiving anything in the Response Body or Header through Listener.
Any Idea how can I get the response in Response Body Also.
JMeter doesn't display response because it doesn't receive the response and we are not telepathic enough to guess why doesn't JMeter receive the response with the limited amount of information you're giving to us, please refer How do I ask a good question for details
You can use a sniffer tool like Wireshark to see what actually happens with the request and if there is any response.
It's also possible to increase JMeter's logging verbosity for the ISO 8583 sampler by adding the next line to log4j2.xml file:
<Logger name="nz.co.breakpoint.jmeter.iso8583" level="debug" />
then inspect jmeter.log file and look for messages related to iso8583 and other suspicious entries
I was getting (channel/HOSTNAME:POST) [receive] In: 1210 *STAN Number(field 11) *Identifier (field 41) in my JMeter logs (with increased logging verbosity for ISO 8583 Messages) but could not see any thing in my View Results Tree's Response Data.
Answer:
Field 11 and Field 41 needs to be same in request as well as in
response. Once I matched both I was able to get response data in
JMeter successfully.
We recently updated apache jmeter from v4.0 to the latest v5.4.3.
The tests are running fine, but we have strange results.
The requests appear with 3 different labels (without suffix or -0 / -1 appended).
timeStamp, label, responseCode, threadName
1643834640785, API call, 200, Load Group 1 1-1
1643834640785, API call-0, 302, Load Group 1 1-1
1643834641189, API call-1, 200, Load Group 1 1-1
1643834640785, API call, 200, Load Group 1 1-2
....
It seems to me this happens, when the same thread calls the API multiple times.
I am not a jmeter and I am not sure why this happens and how to fix it. Also I don't know what information is needed to analyze the problem correctly.
Thanks in advance!
I'm seeing HTTP Status 302 which means redirection (for example from HTTP to HTTPS or from global website to country-specific website), in that case JMeter generates additional Sub-Result.
The "strange" labels is how JMeter calculates throughput for embedded resources and the cumulative execution time of the parent sampler in case of redirects as well.
The question is what do you want to do with this.
The options are in:
Take it for granted given the above explanation
If you want the "strange" labels to be resolved into real URLs - tick "Functional Testing" box in the Test Plan
or add the next line to user.properties file:
subresults.disable_renaming=true
If you want to get rid of these subresults completely - add the next line to user.properties file:
jmeter.save.saveservice.subresults=false

I am Trying to run My IS08583 Script for Multiple Users using JPOS Plugin. However i could find below Output in the Sampler Result. Can anyone suggest what settings needs to be changed in JPOS for running my Script on Multiple users without this Error. Currently i am running only 2 Threads, in which one thread gives successful Output and Other gives error as mentioned below..

DataEncoding: null
When sending and receiving multiple request and response messages over the same socket connection,
jPOS needs to match responses (as they may come in in a different order) to requests.
It does that based on keys it generates for each message, e.g. jmeter-2d8b3043-send.120000003938777.req.
The part 120000003938777 is generated (by default) from the fields MTI (1200), DE41 and DE11 (00003 and 938777 presumably).
If your script does not vary those fields e.g. randomly, as suggested, the same key will be generated
for multiple messages and you get that error when jPOS detects the duplicate key.
Obviously, this makes it impossible to unambiguously match responses to requests.
What you can do is:
vary the fields DE41 and/or DE11, or
in case your messages do not contain those fields, define different keys in the "ISO8583 Connection Configuration" under "Mux Key Configuration" and vary those.
The JMeter functions ${__time()} and ${__RandomString()} are quite useful for that.
Refer also https://github.com/jpos/jPOS/blob/master/doc/src/asciidoc/ch08/qmux.adoc#mti-mapping-and-default-key.
Disclaimer: I am the author of the JMeter ISO8583 plugin.
I have been receiving this error message on particular request - "Value cannot be null. Parameter name: source".
My Scenario is that 1 user will be transacting 5 transaction (Search and Remit). I'm targeting to run 650 Users to 3250 Transaction. The problem is that one particular request which is getting details from the DB, some data is passed but mostly are the mentioned error message above.
I Have 2 CSV Config, 1 from Users, the 2nd is for the Data where the second csv is inside the Loop Controller.
Your application tells you that the request is not correct, it expects a value and you're failing to provide the value. Use Debug Sampler and View Results Tree listener combination to validate the values of the JMeter Variables which are being sent for successful and not successful requests, it might be a test data issue, for example an extra comma in the CSV file will make CSV Data Set config "think" that this is the delimiter for the next column.
I have a .jmx file with two thread groups. The first thread group is for data comparison (DB Vs API) and has a JDBC request where I plugin my SQL script and saves it to a tab delimited file. Then I have a while loop under which I have an HTTP request.
Second thread group for negative scenarios validation.
Below is the structure of the .jmx file
-- Thread Group Name - FX-Rates
-- JDBC Request Name - FX-SQL
-- While loop
-- HTTP Request - FX Rates - API
-- Thread Group Name - Negative Testing
-- Error Codes
I am running JMeter in Non GUI mode using below command.
jmeter -n -t "F:\MY DOCUMENTS\PSM\PSM_Automation\bin\Non_GUI_FX_Rates_Validation.jmx" -l "F:\MY DOCUMENTS\PSM\PSM_Automation\log\Non_GUI_FX_Rates_Validation.jtl"
I see that it is creating log for each individual sampler i.e; SQL and negative scenarios but not for anything under while loop. Below is the log that it created.
Logfile:
timeStamp,elapsed,label,responseCode,responseMessage,threadName,dataType,success,failureMessage,bytes,sentBytes,grpThreads,allThreads,Latency,IdleTime,Connect

Obviously, the kind of sampler result is there:
Error 400: Invalid Date Format,Non HTTP response code: java.net.URISyntaxException,Non HTTP response message: Illegal
character in query at index 80:
https://sys-fxrt-v0.apps.system.pcf.ntrs.com/foreign-exchange-rates?as-of-date=${D_EXCH_RT_EFF}
Obviously that is because the D_EXCH_RT_EFF is not set/resolved in your URL.
That's the problem you're gonna debug.
Obviously.
If you're already doing that (debugging), and run into a problem during it - then describe it please.
And show two things: how you set (initialize) the variable; how you use it, means, literally, show your HTTP sampler (yes, screenshot, at least).
The reasons of not entering the "While Loop" can be in:
While condition is returning false
While condition is wrong
If your While Condition depends on a variable coming from JDBC Request Name - FX-SQL sampler - double check this variable value using Debug Sampler and View Results Tree listener combination.
General "good practice" is running your test with 1-2 virtual users in GUI mode and inspect requests and responses details in the View Results Tree listener. Also pay attention to any suspicious entries in jmeter.log file. Don't run your JMeter test with the full load until you are totally sure that it is doing what it is supposed to be doing.
