I have the following params setup on jmeter, I am running my script in a loop which is creating huge logs(jtl file), Can I log only error responses ?
You can configure JMeter to save response data only for failed samplers by adding the next lines to user.properties file:
jmeter.save.saveservice.response_data=false
jmeter.save.saveservice.response_data.on_error=true
If you want to completely disable saving any metrics for successful samplers add the next line to the same file (however you won't be able to get reliable metrics this way):
jmeter.save.saveservice.successful=false

I am outputting results from 30 tests to a single xml file.
Currently the file includes latency, connection time, and whether it returned OK. I want the endpoint I am hitting to also be shown. My tests run in sequence and output to a single file.
It's Save URL checkbox:
You can also achieve the same by amending JMeter Results File Configuration like:
jmeter.save.saveservice.output_format=xml
jmeter.save.saveservice.time=true
jmeter.save.saveservice.filename=true
jmeter.save.saveservice.latency=true
jmeter.save.saveservice.response_code=true
jmeter.save.saveservice.url=true
and others set to false
Put your changes to user.properties file, JMeter restart will be required to activate the changes.

I am using Jmeter to code and using cmd to run the code.
My requirement is I need to stop the execution of the request when first HTTP request fails.
For ex I have 1000 threads and if it find error in 501 thread ,I need to get at 501 sample, it started for error.
I have the Thread count as shown.
set Action as Stop test on error
And ran this in cmd and result stored as .JTL file
When I viewed that .jti in Summary tree.
I see the below output
Here I see sample count is still 1000 and error% is 7.7%.
How to find out at what sample it got the error
You can inspect the details using View Results Tree listener, by default it shows last 500 sample results, in order to increase this number you need to add the next line to user.properties file:
view.results.tree.max_results=0
also with default Results Save Configuration it shows only a limited subset of metrics like response time, status code, status message, connect time, latency, etc.
In order to be able to see full request and response you can add the next lines to the aforementioned user.properties file:
jmeter.save.saveservice.output_format=xml
jmeter.save.saveservice.response_data=true
jmeter.save.saveservice.samplerData=true
jmeter.save.saveservice.requestHeaders=true
jmeter.save.saveservice.responseHeaders=true
jmeter.save.saveservice.url=true

We cannot say why your test doesn't stop without seeing the full configuration, log file and knowing the nature of the failing samplers
I am new using the Apache JMeter, I am currently using JMeter for stress test to load balancer. There are 2 Web Server pointing to the single database server. All the configuration load balancer was successfully configure and work fine. After using the JMeter, i able to create a different scenario, i.e shutdown one of the web server or removing the index file. JMeter also working fine display all the request and result each request either the thread (user) getting 404 or 200. Any idea on how to create and configure so that JMeter will display and count each the result, i.e How many number getting HTTP-response code 404 or 200 ? It possible to generate the result and transform it into the graph using the JMeter ?
Configuration:
Server
-Thread Group (50 Sample)
-HTTP Request
-Regular Expression Extractor (disabled)
-Response Assertion (disabled)
-View Result Tree
-Debug Sampler (disabled)
-Graph Results
-Summary Report
You do have the results already
Remove all the listeners from your Test Plan, the listeners don't add any value and just consume valuable resources
Run your JMeter test in command-line non-GUI mode like
jmeter -n -t test.jmx -l result.csv
Open the result.csv file with MS Excel or LibreOffice Calc or equivalent - you will have timeStamp and responseCode columns which will allow you to build some form of "Response code over time" chart
Another option is using Response Codes per Second chart:
It is not a part of JMeter distribution bundle, it can be installed using JMeter Plugins Manager
And finally you can store the status code of the response into a JMeter Variable using Regular Expression Extractor configured like:
once done you can add the next line to user.properties file:
sample_variables=statusCode
and plot this custom variable to the HTML Reporting Dashboard
You can generate JMeter dasboard which include Errors summary:
You can create dashboard using existing log file:
jmeter -g <log file> -o <Path to output folder>
Is it possible to see "view results tree " sampler of jmeter in jenkins. I want to see all my request and response data of jmeter in jenkins. i am not able to find it
By default JMeter does not store the response data when it is being run in non-GUI mode, however you can override this by adding the next lines to user.properties file (located in "bin" folder of your JMeter installation)
jmeter.save.saveservice.output_format=xml
jmeter.save.saveservice.response_data=true
jmeter.save.saveservice.samplerData=true
jmeter.save.saveservice.requestHeaders=true
jmeter.save.saveservice.url=true
jmeter.save.saveservice.responseHeaders=true
But be aware that:
It changes results output format to XML so if you have any post processors which explicitly rely on CSV default format (i.e. HTML Reporting Dashboard) - they might fail
Storing request and response data causes massive RAM and Disk IO overheads so JMeter will consume way more memory hence throughput might be lower. It is recommended to use the above settings only for debugging or investigation when something definitely goes wrong and revert them back to defaults once you figure out and eliminate the root cause.
See Apache JMeter Properties Customization Guide for more information on using JMeter Properties and ways of setting and overriding them
I am running Jmeter in non-gui mode. When I load the resulting.jtl file in jmeter I can see sample result but it does not give me sampler request and response data. Help appreciated!
By default sampler request and response data are not stored in the .jtl file. To override this behavior you need to "tell" JMeter to store the data. To do so locate the following properties in jmeter.properties file which lives under /bin folder of your JMeter installation, uncomment and change to "true" values of the following:
#jmeter.save.saveservice.samplerData=false
#jmeter.save.saveservice.response_data=false
Alternatively you can pass these properties during command-line execution via -J key as follows:
jmeter -Jjmeter.save.saveservice.samplerData=true -Jjmeter.save.saveservice.response_data=true -n -t /path/to/your/script.jmx -l /path/to/results/file.jtl
See Apache JMeter Properties Customization Guide for more information on dealing with JMeter properties.
Also be aware of the fact that storing requests and especially responses will have negative impact on your load generator(s) performance.
