I want to pass variable to aggregate report to distinguish request .How to print/pass a variable in aggregate report jmeter?
Option 1: you can add variable to Sampler Name so you will be able to figure out the variable value and distinguish samplers basing on their labels in the Aggregate Report as
Option 2: you can use sample_variables JMeter property. JMeter will append variable values to sampler metrics in results .jtl file. It will not be displayed in the Aggregare Report, but it will be possible to analyze .jtl file with Excel or equivalent.
To use "sample_variables" feature add the following line to user.properties file (it is located under /bin folder of your JMeter installation)
sample_variables=VAR1,VAR2,VAR3
You can "tell" JMeter to store single or multiple variable values along with request metrics.
JMeter restart is required to pick up amended property from the "user.properties" file. Alternative way is providing property via -J command-line argument as
jmeter -Jsample_variables=foo -n -t /path/to/testplan.jmx
See Apache JMeter Properties Customization Guide for advanced information on using, setting and overriding JMeter properties.

Is there a way to generate a report from a .jtl file if I had set some saveservice values to false such as below:
jmeter.save.saveservice.response_message = false
jmeter.save.saveservice.assertion_results_failure_message=false
Its complaining that it cant find them. I tried adding the column manually into the .jtl and just filling it with a null value but that didnt seem to work.
It is possible given the Results File Configuration properties are the same.
So if you run your test on one machine and generating the results on another machine - make sure that the jmeter.save.saveservice. properties are exactly the same, this way you should be able to generate the dashboard normally.
So if you put the next lines to user.properties file:
jmeter.save.saveservice.response_message=false
jmeter.save.saveservice.assertion_results_failure_message=false
the dashboard generation will be successful.
Another option is providing the properties via -J command-line arguments like:
jmeter -Jjmeter.save.saveservice.response_message=false -Jjmeter.save.saveservice.assertion_results_failure_message=false -g -o /path/to/dashboard
See Apache JMeter Properties Customization Guide article for more information on JMeter properties and ways of setting/overriding them.
The order of "columns" is defined under CSVSaveService and as of JMeter 5.3 you cannot configure it, if you decide to save some metric it must be in particular column, i.e. timeStamp will always be the first, elapsed the second, etc.
I figured out you can manually just enter the headers in the jtl/csv file and leave the column empty. As long as you have the necessary columns separated by commas and the saveservice deafult properties are included.
The headers need to be in the right order though as per a normal jtl results file. The headers dont seem to be able to be just added to the end.
My question is - if I run a test via Jmeter, for example , if it's a site which enables you to book a flight, and you choose your source and destination when you record it.
Is it possible to pass different values to the destination field? I mean, maybe a txt file with some destinations and pass it to the Jmeter test and then, you will have some tests which each of them is running with a different destination?
If yes, how can I do it?
It's not necessary that it will be a txt file. Just a way to pass different values to one parameter.
Important: I'm using blazemeter plugin for chrome.
Thanks a lot,
appreciated.
You can use CSV Data Set Config. It is very easy to use for parameterizing variables in the test plan.
Check this article on blazemeter to understand the CSV Data Set Config quickly.
Depending on what you're trying to achieve you can go for:
HTML Link Parser. See Poll Example which shows how you can use it for selecting random values from inputs
You can extract all the possible values from the previous response using a Post-Processor, most probably CSS Selector Extractor and configure each thread to use its own (or random) value from the input
And last, but not the least, you can use an external data source like .txt or .csv file and utilize __StringFromFile() function or CSV Data Set Config so each thread (virtual user) would read the next value from file instead of using recorded hard-coded values.
I am having a search API which will return bunch records(first name, last name, etc). If the DB have the records it will return the attributes with values else it will return as Null. I want to print or write the records for which value is available, Null blocks can be discarded. Could you please guide how to check and capture the same
Depending on where and in what form you want the output the approaches will differ therefore try to be more specific next time, for the time being here is a "generic" solution
Extract data from the response into a JMeter Variables using suitable JMeter Post-Processors. Basically the same process which is used in dynamic data correlation in JMeter tests. Give the variables meaningful names like firstName, lastName, etc.
Define sample_variables property in user.properties file (lives in JMeter "bin" folder) as somma-separated values like:
sample_variables=firstName,lastName,etc.
Next time you run your JMeter test in command-line non-GUI mode the resulting .jtl file will contain the respective values for all defined Sample Variables
I am trying to run a single recording in various different ways without copying the recorded pages.
I have created two Property File Readers that look for:
C:\performance\jmeter\users_${__P(ttype)}.properties
and
C:\performance\jmeter\${__P(env)}_${__P(region)}.properties
where the ${__P(xxx)} variables are passed on the command line as so:
-Jregion=UK -Jenv=dev -Jttype=isolated
These property files load the following variables (for example):
- usercount=25
- duration=1800
- host.name=server1
- host.port=8546
These are used in the HTTP Request Defaults:
${__P(host.name)}
${__P(host.port)}
and Thread Group:
${__P(duration)}
${__P(usercount)}
This works fine. However, if I want to run the same test in the Gui for a single thread (to check it works), these variables are not populated and the test fails.
I can create a User Defined Variable element but these have the format
${xxx}
so cannot be used interchangeably.
Is there any way to do what I'm trying to do here, please?
Option 1: you can pass the same parameters via '-J` arguments as JMeter in the GUI mode respects them as well
Option 2: you can specify your properties values in user.properties file (located in JMeter's "bin" folder) like
usercount=25
duration=1800
etc.
The properties values passed over the command-line will override those, which are specified in the user.properties
See Apache JMeter Properties Customization Guide for more information on using JMeter properties
By the way, you ain't gonna need this Property File Readers, there is a possibility to add extra properties files in JMeter via -q command line argument.
-q, --addprop
additional JMeter property file(s)
Discovered another way to resolve this issue.
The __P() function can take a second argument that acts as the default if the first value isn't resolved.
So
${__P(host.name)}
${__P(host.port)}
become
${__P(host.name,server1)}
${__P(host.port,1234)}
This works as well.
Is it possible to get a CSV file report in JMeter just with only defined regular expression variables values from all the samplers?
Because I have defined sample_variables in JMeter user.properties file. Thanks.
The easiest way is using Flexible File Writer
A little bit harder - suppress all JMeter default result saving configuration via user.properties file like:
jmeter.save.saveservice.output_format=csv
jmeter.save.saveservice.assertion_results_failure_message=false
jmeter.save.saveservice.assertion_results=none
jmeter.save.saveservice.data_type=false
jmeter.save.saveservice.label=false
jmeter.save.saveservice.response_code=false
jmeter.save.saveservice.response_data=false
jmeter.save.saveservice.response_data.on_error=false
jmeter.save.saveservice.response_message=false
jmeter.save.saveservice.successful=false
jmeter.save.saveservice.thread_name=false
jmeter.save.saveservice.time=false
jmeter.save.saveservice.subresults=false
jmeter.save.saveservice.assertions=false
jmeter.save.saveservice.latency=false
jmeter.save.saveservice.connect_time=false
jmeter.save.saveservice.samplerData=false
jmeter.save.saveservice.responseHeaders=false
jmeter.save.saveservice.requestHeaders=false
jmeter.save.saveservice.encoding=false
jmeter.save.saveservice.bytes=false
jmeter.save.saveservice.url=false
jmeter.save.saveservice.filename=false
jmeter.save.saveservice.hostname=false
jmeter.save.saveservice.thread_counts=false
jmeter.save.saveservice.sample_count=false
jmeter.save.saveservice.idle_time=false
jmeter.save.saveservice.print_field_names=false
Hardest: add i.e. Beanshell Listener to write variable value to a separate file. Example code is something like:
import org.apache.commons.io.FileUtils;
FileUtils.writeStringToFile(new File("target_file.csv",vars.get("your_variable_name")));
