Is there any JMeter plugin available natively to send JMeter results to Splunk tcp forwarder? I looked up in jmeter-plugin's site but cannot find one. One other answer in SO suggested to use beanshell postprocessor to send the result. I am fairly new to Beanshell any help to get this done is much helpful.
Instead of sending data to Splunk from JMeter you could do the opposite thing - configure Splunk's input.conf to read JMeter's .jtl results file. See Monitor files and directories article for more details.
Second viable choice would be sticking to JMeter TCP Sampler, I believe it is easier than using any form of scripting
If you are looking for a ready solution you can consider SendToSplunk program which can be invoked via OS Process Sampler

I'm currently testing a 1.5GB download. Does the Save Responses to a File storing the data in the cache first when the request is not yet done? Is it possible to configure the JMeter to write the file while receiving the data?
As of JMeter 5.4.3 the Save Responses to a File listener:
Waits for the full response to arrive to JMeter
Writes it using BufferedOutpuStream via JOrphanUtils.write() function
It's not possible to easily amend this behaviour unless you're willing to write a custom plugin for JMeter
I can suggest a better option: instead of saving the whole file you could:
Tick Save response as MD5 hash? box under "Advanced" tab of the HTTP Request sampler
The downloaded file integrity can be checked using MD5Hex Assertion
The point is that same files have the same MD5 checksum, if the downloaded file's checksum will be different - it means that the file content differs and MD5Hex Assertion will fail the associated Sampler.
As a bonus, this trick will greatly reduce JMeter's memory consumption and you will be able to conduct higher load from the same machine.

I have a bunch of server logs with api requests I'd like to replicate for testing. Is there an easy way to "export" those logs {uri: $path, query: $queryparams} as input for blazemeter to test?
Jmeter is open source. Just modify the source to replay the logs and to handle the user input and dynamic components. Every time you see a new source IP, fork a new thread. Use the delays between requests to define the think time. And you will have created "Web replay," the equivalent of Oracle's DB Replay
There might be a chance that JMeter's Access Log Sampler will work for you if your server is in: Tomcat, Resin, Weblogic, and SunOne.
If it's not you might need to convert the log to the supported format or implement your own versions of LogParser and Generator

I have recorded script through Blaze meter and tried executing thru jmeter after adding com.sun.faces and bttoken. I have tried adding sEntry but unfortunately I didn't find the key.
Issue: It is not performing refresh report activity because I was monitoring in the backed sessions.
Looking into BI4 Web Intelligence Performance Test with JMeter article it should be strEntry and the relevant Regular Expression Extractor configuration would be something like
Actually you can use another approach to recording JMeter tests which can export recorded scripts in "SmartJMX" mode with automatic detection and correlation of the dynamic data, it might help you to come up with the properly correlated version of the load test with the minimal efforts. Check out How to Cut Your JMeter Scripting Time by 80% article for more details.
If you need further help on manual correlation consider including previous sampler response and the next request details into your question
I am pretty new to load testing and whole web thing.
Is there any way to implement things that this Vugen Loadrunner code do
web_custom_request("action",
"{URL}",
"Method=POST",
"Resource=0",
"RecContentType=text/html",
"Referer={refURL}",
"Snapshot=t57.inf",
"Mode=HTTP",
"Body={PARAMETER}",
LAST);
In jmeter? The {PARAMETER} is just a String.
JMeter's equivalent would be HTTP Request sampler.
JMeter's Variables have a little bit different syntax so the equivalent configuration would be something like:
If you want to have full control there is also HTTP Raw Request sampler which can be installed using JMeter Plugins Manager
Also be aware that you can record your LoadRunner script using JMeter's HTTP(S) Test Script Recorder, just start JMeter's HTTP(S) Test Script Recorder and in LoadRunner's Runtime Settings set JMeter as the proxy:
When you run your LoadRunner test JMeter will capture the requests and save them under Recording Controller
More information: How to Convert LoadRunner Tests to JMeter
To send any kind of HTTP Request you can use HTTP Request Sampler
To start with use this practical example : build-web-test-plan and then move to advanced build-adv-web-test-plan

Being a performance tester/engineer/architect brings with it a core ability to recognize patterns associated with success and failure
I am pretty new to load testing and whole web thing.
This is a massive antipattern for success in this field. You need your foundation skills vetted and shored up. You really do need training and a mentor for a period of time.
If your management is asking you to perform in this role, then they should also ensure your path to success. If they are unwilling to fund your training and mentoring period, then I would recommend seeking new management who are more interested in your success and the success of the project.
I have jmeter loading my web service with load at around 2000 events per sec.
I want to log all my requests. Is there any way where i can write all my out going requests periodically? Basically i want to write outgoing requests in csv format every 15 mins?
Is it possible?
I am new to jmeter so a detailed answer will help a lot
Thanks
You can configure JMeter to store request details by adding the next few lines to user.properties file (lives under /bin folder of your JMeter installation)
jmeter.save.saveservice.output_format=xml
jmeter.save.saveservice.url=true
jmeter.save.saveservice.samplerData=true
So if you run JMeter on command-line non-GUI mode .jtl result file will contain all request details.
See Apache JMeter Properties Customization Guide for more details on various JMeter properties and ways of setting/overriding them
Just for reference here are other properties which can be used to define which values can be stored in results file:

It is possible, but quite complex, and maybe won't improve the throughput as you'd hope.
You can add a beanshell listener to your test plan.
Within the beanshell code you can measure time elapsed, and record the current sample to memory.
When enough time has elapsed you can write the memory samples to file and flush memory.
It appears you are trying to allow for the performance of the client logging not affecting the server under test. An alternative approach to logging at intervals (which is going to make your test results look like a sawtooth), you could try using distributed jmeter testing, and have enough clients running to test your server thoroughly, rather than trying to make your client perform better.
Then you can just use the 'Save responses to a file' listener.
If your tests are limited by the client capability, you simply need more client power to test the server, or look at other ways to improve client/test plan performance.
