Anybody please let me know, how to get the response time of each transaction in seconds/minutes/hrs not by milliseconds ?
How to configure the test plan for each transactions separately in jmeter?
for example, transaction : load task, transaction : save task,
transaction : login and transaction : sign out.
in seconds/minutes/hrs ?
It isn't possible on "per transaction" basis but it's something that you configure globally.
Looking into jmeter.properties file in /bin folder of JMeter installation:
# Timestamp format - this only affects CSV output files
# legitimate values: none, ms, or a format suitable for SimpleDateFormat
#jmeter.save.saveservice.timestamp_format=ms
#jmeter.save.saveservice.timestamp_format=yyyy/MM/dd HH:mm:ss.SSS
See SimpleDateFormat JavaDoc for possible values.
You can specify format required by uncommenting and altering jmeter.save.saveservice.timestamp_format property as follows:
jmeter.save.saveservice.timestamp_format=HH:mm:ss
Or specify it as JMeter startup script parameter as:
jmeter -Jjmeter.save.saveservice.timestamp_format=HH:mm:ss -n -t /path/to/your/script.jmx -l /path/to/logfile.jtl
See Apache JMeter Properties Customization Guide for more details on how to make use of different JMeter properties.

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
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.
I am new to Jmeter and working on JDBC. I am interested to know:
How to change field/header names while exporting data to csv file.
How to display elapsed time in seconds instead of milliseconds.
I would really appreciate, if you please define each step. Being a newbie, it would be easier for me to follow.
The field names are defined in the CSVSaveService.java file, you will need to get JMeter sources, amend field names as required and rebuild JMeter. See How to write a plugin for JMeter article for more information
There you can change it in the same file like:
elapsed = Long.parseLong(text) / 1000 // convert ms to seconds
However I wouldn't recommend going for these approaches as there could be side effects in reporting systems.
Instead of patching JMeter you can add a JSR223 Listener and write your own CSV file using Groovy code
For example this is how you can write elapsed time in seconds into a new file called results.csv
def myFile = new File('results.csv')
myFile.append(sampleResult.getTime() / 1000)
myFile.append(System.getProperty('line.separator'))
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!!
