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.

I have connect my PC as master to other PCs and I run the distributed test but all I get is an empty jtl file with only the headers of a table..
What is the problem?
We don't know.
From your beautiful screenshot we can only see that 0 samplers were executed which perfectly explains empty results.
Check jmeter.log file for jmeter master and slave, most probably you will find the reason there.
The most common reasons are:
Incorrect RMI configuration so there is no bi-directional communication between the master and slaves
Your test relies on external data, i.e. uses CSV Data Set Config and you forgot to copy the CSV file(s) to slave machine(s)
Your test relies on JMeter Plugins and you forgot to install JMeter Plugins on the slave machine(s), you can install JMeter Plugins Manager and open the .jmx test plan on the slave - the plugins manager should detect and install at least the majority of the plugins used in the script
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 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?
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.
I was using non-GUI option to perform a distributed load testing with Jmeter from master server A (Linux) to slave server B (Linux). Here's what I did:
./jmeter -n -t xxx.jmx -l results.log -R xxx.xxx.xxx.xxx
By default, Jmeter will write the results file to the master server A. I'm wondering if there's a way to directly store the results file on remote server B.
Thanks in advance!
The idea is they are dumb slaves, possibly without even the means to store data locally. The methods are invoked on a remote processor (RMI) and run from there, but all other resources are kept at the client side.
You could set up a CI server like Jenkins to run jmeter clients in a distributed manner. That will allow you more control over how tests are distributed. I have a jenkins set up that runs jmeter client on a master, with distributed tests to remote (jmeter) slaves, which are also jenkins slaves, tied to jobs that control the workspaces. This means they are never used by jenkins, but jenkins can get results files out of the workspace, aggregate them, and produce graphs using jmeter plugins CMDrunner.
The other possibility is to prefix your sample results with the unique part of the IP address of the current slave. This will allow you to display them aggregated or separately in your results viewer, and potentially write scripts to separate the results out and store them back on the slave they came from.
You could also use samba or similar to share the remote slave drive, and store the results directly there from the master.
If you have only one slave, any of these would be easy to implement, but get more complex as you add more slaves.
Look at sample sender alternative implementations.
Read the concerned paragraph here:

Natively it works like this, an option is not to use distributed mode and run many jmeter instances in non gui mode.
Try jmeter user mailing list and if you don't get an answer maybe open a bugzilla enhancement request.
If you want to build distributed load testing system you can try use Jagger
