How can I log (by using sample_variables=...,...) jdbc/server exec time which we define as (latency - connect time)?
We would like to use the metric for a custom graph in the Jmeter Reporting module.
Add the next line to user.properties file:
sample_variables=execTime
See Sample Variables user manual entry for more information
Add JSR223 PostProcessor as a child of the request which "exec time" you want to measure or put it at the same level as other JDBC Request samplers (see JMeter Scoping Rules - The Ultimate Guide article for details)
Put the following code into "Script" area:
vars.putObject('execTime', prev.getLatency() - prev.getConnectTime())
it will subtract connect time from latency and store the value into execTime JMeter Variable
Now you should be able to follow instructions from Generating customs graphs over time JMeter user manual chapter

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

While trying to write Webdriver sampler with Config/listener element ,I have below issue ,Could any team assist me for the same?
1:- In config /listener element/webdriver browser setup file , if we want to enter some value from external resource (' or if we want to save summary report in PC, Is there any procedure to give unique path that can be run in any workstation /pc/ any directory after giving file name only because if we execute in other station or move file in other directory, everytime we need to change file location?Could you please guide me for the same?
While writing webdriver sampler request,I am able to execute script but i am getting below error in log viewer window and also wanted to break functionality as very small unit label for one webdriver sampler request{launch site/login successfully,validate record, logout} so after searching on google , i used sub sample start or samplestart function multiple time , but i am not getting label name in view tree listener result after setting one jmeter property. Could you please guide me for the same?
3:- Could we run three thread group at same time(all three thread run at same time) or some interval (first and sec run on same time but third start after 10 minute)
Thanks you for giving valuable time in advance?
Thanks Amit
You can give only the filename and JMeter will look for the CSV file and write results file into JMeter's "bin" folder (or the place where you launched JMeter from). You can also use __P() function to parameterize the file name or even path, for example if you do set your CSV Data Set Config like:
${__P(testdata,TestData.csv)}
you will be able to override the path using -J command-line argument like:
jmeter -Jtestdata=/path/to/somefile.csv
If you don't provide the property, default value of TestData.csv will be used. More information: Apache JMeter Properties Customization Guide
You're getting this "Invalid call sequence" error because you have duplicate WDS.sampleResult.sampleStart() function call, just remove one of them and that would be it.
Add a Constant Timer as a child of the first request or Flow Control Action sampler at the beginning of the Thread Group 3 and configure them to sleep for 600000 milliseconds.
My JMeter test:
Iterate over a CSV file (logins.csv) with login credentials, and their unique identifier user a CsvDataSetConfig
Sign in
Based on the login credentials (unique identifier from logins.csv), identify and load a second file in the format of <user_identifier>_invoices.csv which then has the necessary path to view an invoice for that user.
Simplified test setup:
ThreadGroup
> CsvDataSetConfig - file: logins.csv, variables: user_identifier,email,password, sharing_mode: all threads
> `SignIn` TransactionController using email and password from above CSV file to login via series of HTTP Requests
> UserParameters - USER_IDENTIFIER,INVOICE_CSV_FOR_USER
> BeanShellSampler
props.setProperty("USER_IDENTIFIER", vars.get("user_identifier"));
props.setProperty("INVOICE_CSV_FOR_USER","${__P(USER_IDENTIFIER)}_invoices.csv");
> WhileController - condition: ${__javaScript("${invoice-id}" != "<EOF>",)}
> CsvDataSetConfig - file: ${__P(INVOICE_CSV_FOR_USER,)}, variables: invoice-id, sharing_mode: current thread
> `ViewInvoice` TransactionController with HTTP Request to url `../${invoice-id}`
# logins.csv
c7beaa99c6d99fa7754fc2213f9b17b8,foo#example.com,password321
9c8466bee65e39c9d3cf715e42933c3b,bar#example.com,password456

Problem:
In local JMeter, seeing requests to invoice urls being made with incorrect invoice-id for the business. So seems the parameters are not being treat correctly between threads.
In BlazeMeter, seeing the content of the while controller never being hit.
I've tried loop controllers, having 50 rows per _invoices.csv file, but not got anywhere with that either. I also originally started off with
User Defined Variables rather than User Parameters, but the latter seems to be what I should be using for this use case.
Threads are running at the same time and sharing JMeter properties.
In your test plan each thread sets the property USER_IDENTIFIER. So this and other property can/will be overriden by different thread(s) and create inconsistency.
I suggest you save (and get) in variables which aren't shared by threads:
vars.put("USER_IDENTIFIER", vars.get("user_identifier"));
vars.put("INVOICE_CSV_FOR_USER"," ${USER_IDENTIFIER}_invoices.csv");
Also about beanshell, JMeter advice to change to JSR223
Since JMeter 3.1, we advise switching from BeanShell to JSR223 Test Elements (see JSR223 section below for more details), and switching from __Beanshell function to __groovy function.
How to generte csv file and load csv using response time graph listener?
Can any one help me in detail that how we find response time in jmeter ?
If you run JMeter in command-line non-GUI mode as follows:
jmeter -n -t /path/to/your/test_plan.jmx -l /path/to/results_file.jtl
your results_file.jtl content will look like:
1409124780902,182,Logon,200,OK,Thread Group 1-1,text,true,214,0
1409124781219,153,Logout,200,OK,Thread Group 1-1,text,true,110,0
where second column is page response time in milliseconds.
Other values are:
"1409124780902" - current time stamp in ms
"182" - page response time
"Logon" - sampler name
"200" - Response Code
"OK" - Response Message
"Thread Group 1-1" - Parent Thread Group name, thread number and iteration.
"text" - response data type
"214" - response data size in bytes
"0" - latency
Once your test run is done you can open JMeter GUI and load this results_file.jtl into the listener of your choice.
You might also be interested in JMeter Plugins Extras Set which is capable of generating nice looking and easy understandable response-time related graphs to wit:
Response Times vs Threads
Response Times Distribution
Response Times Percentiles
You can get it by adding Reporters.
Please keep in mind Reporters is cpu and memory intensive components and thus should not be used while actual load test.
But for sample testing you can use it and for load test run you can get response time, average,throughput etc by saving output to jtl file in JMeter.
For normal/sample run
Aggregate report gives Average response time, min, max, median etc.
Summary report also gives the same with less details,
While performing actual run you can save output of these reporters in a jtl file. After the test results can be analyzed from jtl files.
I am new into Apache Jmeter. Basically I want to load test our couple of thrift APIs but have no clue where to start with. It is in java where api takes 2 parameter and then send java object as response.
Any pointer would be very helpful.
JMeter isn't especially for it but it's flexible enough to support your use case.
There is an extensibility mechanism which uses BeanShell. JMeter provides BeanShell Sampler which is capable of invoking Java code, including using external jars.
Simple usage:
Start with empty JMeter project
Create a Thread Group with all defaults (you can play with number of threads, ramp-up, etc)
Add a BeanShell Sampler with following code:
Thread.sleep(2000L);
Add View Results Tree listener
Save and run
You should see a green triangle (or triangles) basing on your number of threads and loops) with output like following:
Thread Name: Thread Group 1-1
Sample Start: 2013-11-02 14:48:11 GMT+03:00
Load time: 5030
Latency: 0
Size in bytes: 0
Headers size in bytes: 0
Body size in bytes: 0
Sample Count: 1
Error Count: 0
Response code: 200
Response message: OK
If you use any of techniques to analyze results, i.e.
JMeter embedded listeners like Aggregate Report, Summary Report, Graph Resuls, etc.
Storing results to CSV file and opening them with Excel or equivalent (see jmeter.properties file under /bin directory of your JMeter installation. Properties prefix is "jmeter.save.saveservice."
JMeter Ant Task (see Test.jmx and build.xml in /extras folder under your JMeter installation)
JMeter Results Analysis Plugin
You'll see your request(s) success rate, min/max/average times (something like 2 seconds I guess) and some more information (depending on your configuration).
Particular your use case assumes
IMPORTANT Placing thrift (or whatever) jars under lib/ext folder (or you won't be able to access your APIs
importing classes you need to test somewhere in BeanShell Sampler
import yourpackage.YourClass;
Invoking methods you want to test from BeanShell Sampler
(optional) do some assertions on responses. i.e.
if (yourresponse != yourexpectedresponse){
IsSuccess=false;
ResponseMessage= "Test Failed";
}
Hope this helps
You can use JSR223 Sampler + Groovy (add groovy-all.jar in jmeter/lib) and look at this client example, see NonblockingClient code for an example:
http://www.javacodegeeks.com/2012/03/apache-thrift-quickstart-tutorial.html
Make your groovy code call a least the following at end:
SampleResult.setSuccessful(true/false)
SampleResult.setResponseCode("code")
SampleResult.setResponseMessage("message")
See:
http://jmeter.apache.org/usermanual/component_reference.html#JSR223_Sampler
And of course, ensure you add the required dependencies in jmeter/lib.
I have writtena CustomThriftSampler for JMeter to load test HBase through thrift service. You can get the details about it at my blog - http://1-st.blogspot.in/2013/12/load-testing-thrift-services-custom.html . Couldn't create a generalized code. Anyway its simple and starightforward java code. Anyone could try it. If time permit I shall write a generalised code and commit to github!!
