I'm using Jmeter to get daily results of website performance, specifically, the render time (which I calculate using the sum domComplete - domLoading).
I end up with the result as a new var, but I don't know how to take that amount and transfer it to a Jmeter graph to display the results. My code is below:
WDS.sampleResult.sampleStart();
WDS.browser.get('http://www.vivastreet.co.uk/');
var completeTime = WDS.browser.executeScript('return window.performance.timing.domComplete;');
var loadingTime = WDS.browser.executeScript('return window.performance.timing.domLoading;');
var renderTime = completeTime - loadingTime;
WDS.log.info("Render time = " + renderTime);
WDS.sampleResult.sampleEnd();
The functionality is available only in JMeter 5.0, if you're on a previous version - you will have to upgrade, moreover it is highly recommended as per JMeter Best Practices
Store the result variable into JMeter Variables using WDS.vars shorthand. Add the following line before WDS.sampleResult.sampleEnd()
WDS.vars.put('renderTime', renderTime.toString())
Store the values into .jtl results file using Sample Variables property and configure JMeter HTML Reporting Dashboard to plot the custom value Add the following lines to user.properties file:
sample_variables=renderTime
jmeter.reportgenerator.graph.custom_testGraph.classname=org.apache.jmeter.report.processor.graph.impl.CustomGraphConsumer
jmeter.reportgenerator.graph.custom_testGraph.title=Rendering Time
jmeter.reportgenerator.graph.custom_testGraph.property.set_Y_Axis=Page Rendering time
jmeter.reportgenerator.graph.custom_testGraph.set_X_Axis=Over Time
jmeter.reportgenerator.graph.custom_testGraph.property.set_granularity=60000
jmeter.reportgenerator.graph.custom_testGraph.property.set_Sample_Variable_Name=renderTime
jmeter.reportgenerator.graph.custom_testGraph.property.set_Content_Message=Rendering Time :
Restart JMeter to pick the properties up

I have below values
String CurrentTime1=${__groovy(${__groovy(Date.parse('yyyy-MM-dd hh:mm:ss.SSS','${Modified_date_1}').getTime(),)},)}
log.info("Current time1 ----> "+CurrentTime1);
String beforetime=vars.get("beforetime");
log.info(" after time -->"+beforetime);
Result:
Current time1 ----> 1611495406402
after time -->1611495402100
As there are stored in string, i am not able to get the difference between these values. Can you please help.
I need to get the difference between current time and before time which are dynamic values.
If you want to do this in Groovy - you need to convert the string to Long like:
def before = vars.get('beforetime') as long
def current = vars.get('CurrentTime1') as long
def delta = current - before
def deltaAsString = delta as String
If you prefer using JMeter Functions - you can go for __longSum()
${__longSum(${CurrentTime1},-${beforetime},)}
More information on this and other JMeter Functions: How to Use JMeter Functions - Part III
But don't mix both approaches like inlining JMeter functions in Groovy code, as per JSR223 Sampler documentation:
When using this feature, ensure your script code does not use JMeter variables or JMeter function calls directly in script code as caching would only cache first replacement. Instead use script parameters.
I capture 6 elements using a regular expression. say
Variable : UserDetails
Regular Expression : loadHeadWorkFlow\('(.+?)','(.+?)','(.+?)','(.+?)','(.+?)','(.+?)','/I
Template : $1$$2$$3$$4$$5$$6$
Now I could access these values via UserDetails_g1, UserDetails_g2.....UserDetails_g6
Next, these 6 values need to be encrypted using a javascript file. The file contains the logic.
How should my code be using JSR223 post processor?
The steps that I followed:
1.
load('Encryption.js');
var result = encrypt("${UserDetails_g1}","password");
log.info("encrypted value is "+result);
vars.put("LoginDataString",result);
var result1 = encrypt("${UserDetails_g2}","password1");
vars.put("UserId",result1);
var result2 = encrypt("${UserDetails_g3}","password2");
vars.put("RoleId",result2);
First value is encrypted correctly. But the other values aren't correct. If I add individual post processors for every variable. All the encrypted values show correctly.
Is there a way where I could use a single post processor to perform all the 6 encryptions. Thanks in advance
Regards,
Ajith
Use vars instead of ${} syntax
var result = encrypt(vars.get("UserDetails_g1"),"password");
log.info("encrypted value is "+result);
vars.put("LoginDataString",result);
var result1 = encrypt(vars.get("UserDetails_g2"),"password1");
vars.put("UserId",result1);
var result2 = encrypt(vars.get("UserDetails_g3"),"password2");
vars.put("RoleId",result2);
From JMeter perspective there is no problems, just check that your UserDetails_g2 variable has anticipated value using Debug Sampler and View Results Tree listener combination., the you might want to check this encrypt() function implementation.
Another possible reason is this JavaScript language selection itself, the Nashorn engine performance is a big question mark when it comes to the load, according to JMeter Best Practices it's recommended to use Groovy language for scripting so you might want to consider re-writing the function in Groovy
I am able to extract values for many variables and are showing in Debug Sampler.
Is there any way to save these all variable values to a CSV file?
I found a solution (using BeanShell script) to save multiple Jmeter variable to CSV but I want all variables values to a single CSV, so that I can use the CSV file for next thread run.
Here is the snapshot of one of the Debug Sampler:

Add JSR223 Sampler to your Test Plan (where you want variables to be saved)
Put the following code into "Script" area:
def csv = new File('vars.csv')
vars.entrySet().each {var ->
csv << var.key + '=' + var.value + System.getProperty('line.separator')
}
That's it, you will have vars.csv file created in JMeter's "bin" folder having all variables listed. You might also want to replace = with , for better CSV Data Set Config compatibility.
vars is a shorthand to JMeterVariables class instance, it provides read/write access to all JMeter Variables.
Also be aware that starting from JMeter 3.1 users are encouraged to switch to JSR223 Test Elements and Groovy language so consider migrating to Groovy as soon as it will be possible. See Apache Groovy - Why and How You Should Use It for more details.
I'm trying to create a simple counter that will print the iteration number to the log.
the problem is that I didn't find a way to initialize the int value of i to 0.
if I'll do it inside the Beanshell script it will keep initializing, I need it to run only once at the beginning of the test.
My code:
int i=0;
log.info(string.valueOf(i));
i=i+1;
Add Once Only Controller, under it JSR223 Sampler with the initialization
vars.putObject("i", 0);
Then you can increment it after it (not under the Controller) with other JSR223 Sampler:
myI = vars.getObject("i")
log.info(String.valueOf(myI));
vars.putObject("i", ((Integer)myI+1));
It is recommended to avoid scripting where possible, and if you cannot live without scripting you should be using the most performing option which is JSR223 Test Elements and Groovy language.
Particularly your case can be implemented without any scripting, you can use the following JMeter Functions:
__log() - which prints an arbitrary message to jmeter.log file
__iterationNum() - which returns the number of current iteration
So if you use the statement like: ${__log(Current iteration is: ${__iterationNum},,,)} JMeter will return it where the function is called and additionally print the corresponding message to the log file.
Demo:
You can install __iterationNum() function as a part of Custom JMeter Functions bundle using JMeter Plugins Manager
I am creating a JMeter jmx file dynamically by using JMeter APIs. I am able to add a ThreadGroup within a TestPlan and a JavaSampler within the ThreadGroup. But when I add a CSVDataSet element within the Java Sampler, it does not get saved properly.
The following code is used to create a new CSVDataSet element
CSVDataSet csvDataSet = new CSVDataSet();
csvDataSet.setName("CSV Data Set");
csvDataSet.setComment("Sample CSV Data Set");
csvDataSet.setDelimiter(",");
csvDataSet.setFileEncoding("");
csvDataSet.setFilename("d:\\jmeter\\data.csv"); // variable
csvDataSet.setQuotedData(true);
csvDataSet.setRecycle(true);
csvDataSet.setShareMode(shareMode.all);
csvDataSet.setStopThread(false);
csvDataSet.setVariableNames("firstname, lastname, email"); // variable
csvDataSet.setEnabled(true);
When this is saved using SaveService.saveTree, the final jmx does not contain all the values which were set.
<org.apache.jorphan.collections.HashTree>
<CSVDataSet testname="CSV Data Set Config" enabled="true">
<stringProp name="TestPlan.comments">Sample CSV Data Set Config</stringProp>
</CSVDataSet>
<org.apache.jorphan.collections.HashTree/>
As seen above, only the test name, enabled, and comments are added. The rest of the variables are completely ignored.
Is there something that needs to be set in order to get all the values as expected?
or is this a bug in JMeter? I am using version 2.11
The basic code is as per section 4.3 from following link
http://blazemeter.com/blog/5-ways-launch-jmeter-test-without-using-jmeter-gui
To that I add the code shown above. The way it is added is,
testPlanTree.add("testPlan", testPlan);
testPlanTree.add("loopController", loopController);
testPlanTree.add("threadGroup", threadGroup);
testPlanTree.add("httpSampler", httpSampler);
testPlanTree.add("csvDataSet", csvDataSet);
SaveService
.saveTree(testPlanTree, new FileOutputStream("d:\\test.jmx"));
output of CSVDataSet block is as shown above.
After looking into the JMeter source code, it seems all the properties are set using the setProperty function rather than the individual setter functions. So putting the following code does the job of creating the CSVDataSet element properly.
csvDataSet.setProperty("delimiter", ",");
csvDataSet.setProperty("fileEncoding", "");
csvDataSet.setProperty("filename", "d:\\data.csv");
csvDataSet.setProperty("quotedData", true);
csvDataSet.setProperty("recycle", true);
csvDataSet.setProperty("shareMode", "shareMode.all");
csvDataSet.setProperty("stopThread", false);
csvDataSet.setProperty("variableNames", "var1, var2, var3");
Not sure why setters are not used in the code, but this seems to be the way to go for now
It is clearly not a bug in JMeter otherwise CSV Data Set could not be saved.
It is probably an issue in the way you build the HashTree, but unless you show the full code, you cannot get help.
By the way, as I said in a previous answer, what you are trying to do to build different tests based on input parameter is not good idea IMHO, the approach will be very fragile towards upcoming versions of JMeter.
JMeter provides ways to do it that you should follow.
