Friends,
I am running JMeter on remote servers in a different timezone. The HTML reports show all times (start, end, graphs) in the timezone of those remote servers, but I'd prefer to view them in my local time.
I have tried many of the jmeter.reportgenerator properties, including jmeter.reportgenerator.start/end_date, but nothing has produced the results I want. Any way to do this?
We don't know what results do you "want".
JMeter saves the request start time in milliseconds since the beginning of Unix epoch therefore the .jtl file is timezone-agnostic
So if you run the test on remote machine and then generate the dashboard on the local machine - test start time will be your local.
If this is not something you "want" as well and you "want" more flexibility you might "want" to put the timezone you "want" into system.properties file (lives in "bin" folder of your JMeter installation)
user.timezone=US/Alaska

I want to save Jmeter aggregate report to project's target folder with timestamp,so that everytime I run the tests I get the new unique report, irrespective of OS.
I tried by providing this path /target/jmeter/results/aggReport.csv but it saved it in C:/target/jmeter/results/aggReport.csv Also there was no time stamp.
E.g. 100320182130aggReport.csv which is mmddyyyyhhmmaggReport.csv
This question is in continuation of soemthing I wanted to achieve here and suggested by Dmitri Jmeter: Test plan has two thread groups but it generated only 1 jtl report
I am using Maven, Java 8, Windows 7
Update:
I tried:
In case of JMeter test execution via Maven JMeter's working directory (or Java user.dir property) points to target/jmeter/bin folder so you need to construct the desired path relative to it
Your path starts with / which means it is absolute and points to root folder of the file system
You need to include __time() function into the resulting filename if you want the result to be prepended by the timestamp
Assuming all above your listener "Filename" field should look like:
../results/${__time(MMddyyyyhhmm,)}aggReport.csv

I have three slaves (jmeter-servers) running on EC2 instances, and in one case – (1) JMeter GUI on a local laptop, on another – same test plan (2) running from a command line on yet another EC2 instance.
In case of GUI I can see all the aggregated numbers for Throughput, 99%, etc. in – well, GUI. I'm creating a jtl file with Aggregate Report listener.
From watching Datadog charts monitoring the application server parameters (CPU usage, memory, etc.) I see that in case of a command line and everything on EC2 load is more than twice higher than when my local laptop is communicating with the jmeter-servers, meaning probably that the network becomes a bottleneck. So I want to run everything on EC2.
But then – how do I get access to the same aggregated numbers when I'm running from the command line when all four machines are EC2 instances? The huge jtl file contains records for each transaction, not the aggregated one line of the entire run result.
On an attempt to download that jtl from EC2 and open it in GUI on a local laptop it generates some error instead of showing aggregated data.
Am I using a wrong listener to get to the summary data? (Tried Summary Report – it creates even larger jtl file, not the one line I'm looking for.)
Problem in this case is not running scripts via JMeter GUI. Instead it is related to network.
I had a similar distributed setup in EC2-environment and I successfully executed heavy load tests in GUI mode. In my case, all my JMeter (master/slaves) were running on EC2 instances (windows environment). So, I will recommend you to setup your JMeter (Master) on EC2 and run scripts via GUI mode.
If you still want to run in command line mode then you simply need to pass command to create jtl file while the script runs on command line. Later on you can use this JTL to generate any JMeter report as per requirement. For more details check..
Jmeter - Run .jmx file through command line and get the summary report in a excel
jmeter -n -t /path/to/your/test.jmx -l /path/to/results/file.jtl
Please refer to Dmitri answer in following question to reduce JTL size.
How can we control size of JTL file while running test from Non GUI Mode
I know that we can export/save results of a listner in csv or xml format.
But what i want is to save the listner result once the script has been run.
There seems to be no way of doing this. currently giving a file path in a listner will work only before the execution begins not after it is over.
As per JMeter Performance and Tuning Tips guide it is recommended:
To use non-GUI mode for tests execution
To disable all the listeners during the test run
On test completion you should be able to open .jtl results file by the listener of your choice.
If you need to store some specific data required by this or that listener, take a look into jmeter.properties file (lives in /bin folder of your JMeter installation) and amend properties having "jmeter.save.saveservice." prefix according to your plans.
Perhaps Automatically generating nice graphs at end of your Load Test with Apache JMeter and JMeter-Plugins guide can also help.
If I have jmeter running with 4 remote servers (load generators) and 1 local server (controller) is there a way I can pass a timestamp from the local controller to all 4 remote servers?
I want to create a screenshots directory on each of the remote servers with the timestamp including seconds. Im creating a new directory for every test that is run and need the directory to be the same across all 4 remote servers. The test plans run locally so calling __time() gets the local time of each server and is not usually exactly the same.
You can create a property at jmeter startup on the controller, which holds the system time.
Use option -G so that the remotes get the property.
ie something like -Gserver_time=%date%_%time% (windows), then use ${__P{server_time}} in your directory name on the remotes.
Ok so I set up my JMeter to run remotely using one slave computer (possibly more to come), and it's working out for the most part EXCEPT that I can't fetch the response time over time-graphs function using the JMeter plugin. I'm still able to use the "PerfMon Metrics" tool to get the CPU/Memory values from the slave computer, so I don't understand how I'm not able to get the response time results.
Does anyone have any experience using that function?
I would check the master- slave configuration: be sure that
the same Jmeter release is used
same directory tree structure is used
Jmeter-plugins are installed on both systems
...
If you use a standard "Summary report" listener, and save data to a file in the master, then you can reload and analyse the data off line with any listener.
