I am running the performance test in jmeter. in the summary report std div values are showing 0.0 but at the total column it is showing 1855.88.please check the std div column in below image
I am not understanding what is the issue in std div column if the values are 0.0 then total value should be 0.0 right?
Value of 0.0: you have executed each Sampler only once, there is no "deviation" in response times because there is only one result. If you run your test with 2 iterations you will see "deviation" values
Value of 1855.88 is the deviation for ALL executed Samplers, you have 25 total requests with different response times and the deviation reflects the difference in them.

I have a login scenario to be tested for 10000 users, which contains phone# as input and have given in csv file. Im able to perform load testing for 10000 users and able to show the report with total samples, throughput etc post exporting to a file. However issue is customer wants proof that we are giving input as 10000 users and not using loop eg(500 threads * 2 loops). Kindly help with suggestions if we have any option to show that we are using 10000 unique users.
There is a listener called Active Threads Over Time (can be installed using JMeter Plugins Manager) which shows how many users were active during this or that phase of the test
jmeter.log file contains information how many threads were started for this or that Thread Group
.jtl results file contains number of active threads, both overall and in the current Thread Group
HTML Reporting Dashboard contains the Threads Over Time chart
Is there sum of all response times in JMeter HTML report?
I know JMeter produces excellent data like median etc, but there is need to have sum of all response times.
Is it possible to see it somehow?
JMeter's .jtl result files are normal CSV files so you can import it into MS Excel or equivalent and invoke SUM function on the elapsed column
If you have only one iteration and several requests - you can put all the requests under the Transaction Controller and it will report the cumulative execution time of all its children
It's possible to use Backend Listener so JMeter would send results to a database, once done you should be able to create a query in the DB or in Grafana to display the cumulative response time
I used option 2 from Dmitri's answer recently and it worked perfectly for me in JMeter 5.4.1.
In the Transaction Controller remember to click the "generate parent sample" tick box.
Then in the results tree and HTML dashboard, you will see individual response times for each call and a parent time for the controller.
I found Jmeter captures the Response times of a request that had failed in its aggregate report
If i check Successes Check box, i get only success Response times, Samples, Throughput and KB/sec.
And if dint check anything i could see both Successes and failures in all columns
Is there a way in JMeter to get aggregate report with success response times alone but other columns should get total counts (that include both Successes and failure counts) in #Sample, Total errors, Throughput and KB/Sec as it is
Required Aggregate Report
At present, i collect data through two simple data writers with checking success check box in one (A) and both in another(B). and load it in two aggregate report listeners and manually copy response times section from replace in csv from B so that i get samples, Errors, Throughput & KB/Sec containing both success and failures requests and response times alone from only successes
Simple data writer config
SimpleDataWriterConfiguration
Please let know any other way to acheive this
You have 2 options:
Simple option - add 2 Aggregate Reports:
Successes only
Both successes and failures
Take count from second report, and everything else from the first.
However, saving CSV with raw data is more efficient than having 2 Aggregate Reports, and you already have it (almost) so
Option 2 - save all data into single CSV, and use some tool (linux command line tools, Excel, etc) to sort/parse draw conclusions. You don't need 2 files in this case, since you can always calculate separate totals for success and failure, as well as calculate total of the both from the same file: successes can be filtered by, for example, OK in their responseMessage field.
I have been performing load execution which simulates users concurrently.
However, I don't need the data for the entire run. I need the data during the peak period only.
Can anyone suggest a listener or any method which will provide me the data for a specific period excluding the data of the Ramp Up and Ramp Down period.
Option 1
If you look into 1st line of your .jtl result file you'll see something like:
1403191911666,38,Dummy Sampler,200,OK,Thread Group 1-1,text,true,0,0
Where first column is current time stamp in milliseconds from Unix Epoch start
So if you move out 3 last digits you'll get test start timestamp in seconds.
If your ramp-up is i.e. 300 seconds, just add 300 * 1000 to it and trim your results file to start with 1403192211XXX
Do the same for last N lines depending on your ramp-down time.
Analyze trimmed .jtl file as usual
Option 2
Use free Blazemeter Listener to analyze your test results online, it has:
Possibility to limit time frame to "interesting" slot
Possibility to compare different test runs results
Hope this helps.
I Have a Thread Group created in my Test Plan. I have set the Thread Group to run 20 Threads with Ramp Up Period as 0 and Loop Count as 1.
Now i have created 5 JDBC Sampler Request each which runs different queries against the same Database, so when i start the test , it should kick start 100 queries (20 * 5)
I also generated a Summary report and copied pasted parts of that report.
Sampler Label No of Requests per Sampler Average( in milliseconds)
------------- -------------------------- --------------------------
MYSQL JDBC Request 1 20 8571
MySQL JDBC Request 2 20 5154
MySQL JDBC Request 3 20 5927
MySQL JDBC Request 4 20 1290
MySQL JDBC Request 5 20 1449
TOTAL 100 4478
In the Summary Report taht i have compiled above, what does average of 4478 milliseconds mean?
Does this mean that it took 4478 milliseconds to run 20 threads on an average ? or does it mean that it took 4478 milliseconds to run 100 queries?..can someone help me here. I could not find this information anywhere in the Jmeter apache documentation.
Thanks in advance.
As per this documentation:
https://jmeter.apache.org/usermanual/component_reference.html#Summary_Report
Average : The average elapsed time of a set of results
So it means its it:
Sum of all request's response time / total number of requests
