I am trying to collect CPU , Memory of the server when i am running it on GUI mode i am able to collect data but same when I run in non-gui mode do not capture data for CPU and MEMORY but shows data of request sent.
Have you added a path to where the data must be saved at?

Actually currently I working on performance testing using JMeter and I want to find memory utilization and CPU utilization here I use perfmon plugin and now generate report for memory utilization and CPU utilization so help for how to generate report ?
You can generate charts images out of the PerfMon Metrics Collector listener output file using JMeter Plugins Command Line Tool
Configure the PerfMon Metrics Collector listener to store the values into .jtl results file, as per documentation:
If you run JMeter in non GUI mode and want to save monitoring data to file, just configure result file saving in GUI as you do with other listeners. After running the test you may load saved file into GUI and see the values timeline.
Once done you can create the image from the .jtl file:
JMeterPluginsCMD.bat --generate-png perfmon.png --input-jtl perfmon.jtl --plugin-type PerfMon
and you will get the image with your charts:
I have 1 master and 2 slave machines setup. I want to create two separate summary report, one for each slave.
I know the question in duplicate of this question, but the solution provide does not work for me.
JMeter Slave Reporting in Distributed Testing
In my test plan I have summary report and have added "filename"(or complete path) under write results to file.
When I execute my test plan, result file is saved in master system with combined results of both the slaves. How can I get the response times of the requests executed with each slaves separately?
If you add a Listener to your Test Plan and configure it to save results into a file it will create a results file on each slave machine so once your test is done you will be able to fetch these results file from slaves and perform required analysis.
Assuming your configuration is good you should have 1 cumulative result on master and 2 separate results on each slaves.
Another option is using __machineName() or __machineIP() function as a sampler label prefix (or postfix) so you will be able to distinguish samplers coming from different slaves in the main .jtl results file. This approach will allow you to avoid unnecessary disk IO overhead during test execution required to generate an extra file with the results.
Once you test finishes you will be able to split main .jtl results file using Filter Results Tool to generate separate results files per slave basing on slave machine hostname or IP address.
You can install Filter Results Tool using JMeter Plugins Manager:
AS we know Jmeter have 2 mode to run test plans: single and master-slave mode
in single mode Jmeter summary report listener will collect min, max, stddev, error%,etc data and write in a file..
but in master-slave mode, these information are record by master server, and I have checked the Jmeter summary report codes, I can't understand which extends, methods or which codes make Jmeter slave servers can communicate with master server to let master server record these data, same question in Simple Data Writer listener.
So, can anyone help on this question, thank you very much!
Jmeter's slave communicate with master thanks to Java RMI. For this reason you need to start RMI registry before test. Since version 2.3.1 you don't need to do it manually, Jmeter server wil, take care of this.
I am performing distributed testing using JMeter and getting collective result of all slaves on Master JMeter GUI.
Please let me know if it is possible to capture separate reports for each slave?
For example, I have configured 2 Slaves + 1 Master JMeter. On executing the test, I would like capture separate report of each slave.
Thanks!!
You can get per-slave results as follows:
Add a Listener or your choice to Test Plan
Specify Filename in "Write results to file" section and choose what you need to store via "Configure" button
Once test finishes you'll have to collect result files from slave machines
Be aware that:
By default not everything can be stored, i.e. response data is being removed form successful samples
Listeners have their cost. See Greedy Listeners - Memory Leeches of Performance Testing to get an idea regarding impact and why it is better to have them off during load test.
For your case, don't use distributed testing, just launch 1 separate JMeter per slave machine.
How can I measure the server side performance of server in NON-GUI mode, I have been running the server agent on the server side but still I am not able to generate any graph from server side in JP#GC-Graphs Generator.Can anyone suggest me a way toow to proceed on this .
I have founded the way to Measure the Server side performance. By using PerfMon Metrics Collector which is an extra plugin from JMeter I can record Performance data by writing it to a file(JTL/CSV).
Steps
1.Add PerfMon Metrics Collector in you jmx file as listerner
2.Add the fields which you want to measure and in write results to file option, write it to a file in JTL/CSV
3.Run the server agent on the server side.
4.Run the Test with the command prompt/ batch file .
5.After completion of tests you will be getting a (JTL/CSV) file in the configured location, you can open this using PerfMon Metrics Collector and can see the graphs.
