Can Jmeter master be used as a load generator instance in distributed testing framework? Since we mention host IPs, will it work to mention localhost and generate load from master?
Thanks,
Madhav
If you are launching from JMeter UI to start all instances - 127.0.0.1 (localhost) is available.
Both JMeter documentation pages are good source of information.

What is Jmeter Engine ? Is it same as Jmeter instance we have on our machine ? .. I want to understand difference between Jmeter instance and Jmeter engine , also how can we setup multiple engines on same machine so that I can put more load on application through difference engines..
I read somewhere, where one of the Jmeter expert mentioned that we can use 300 vusers at a given time , is that correct ? I dont see any limit on vusers I use in Jmeter thread group.. I can enter any number.. please clarify
Yes, Jmeter engine and jmeter instance is related terminology. One Jmeter engine can generate one instance of jmeter.
Set-up for configuring two Jmeter engines on same machine:
Pre-requisite:
Jmeter should be installed on both machines
Steps:
1.Set-up master machine -
Add machine2 ip (slave machine ip) in jmeter.properties file of machine1 (master machine)
2.Set-up slave machine - Run Jmeter-server.bat from machine2. This will make machine2 as slave
3.Launch Jmeter from machine1. You will be able to see slave engine ip in remote start
4.You can use remote start option, this will run Jmeter test cases from both the machines
I am in need to do Performance testing using Blazemeter for my site established in QA Environment.
I am doing testing for my site established in QA with the help of VPN connection and now I wonder how to do performance testing-Blazemeter on it and how to connect/establish connectivity on it.
Please help me on this....
Check this link.
Did you check with Blazemeter first?
You also need to check with your Network team! You might not want to do your load testing through a VPN connection which is not going to give you accurate results. It is better to expose the staging/PROD clone environment outside the network for the load testing - This is the process we follow.
Solution:
Got update from Blazemeter:
"First, you'll need to whitelist our IPs, so please refer to our IP ranges list:
https://guide.blazemeter.com/hc/en-us/articles/207420645-What-IPs-are-sending-the-traffic
Then, as long as you have the respective credentials to access the VPN, and run your test locally in Jmeter against the target server successfully, you may run your tests in Blazemeter as desired"
We got to buy dedicated IP from them and need to whitelist it from the Network team. Now the connection would have established and can start doing Performance testing.

I need to check the nginx server performance using jmeter to perform the load testing,I had searched and found that jmeter support tomcat server ,kindly help me with any open source pulg in to check the server performance
There is no built-in support of collecting nginx server health metrics (like Tomcat) in JMeter, however you can consider using the relevant plugin.
You will need:
PerfMon Server Agent - on nginx server side
PerfMon Metric Collector - on JMeter side (comes with JMeter Plugins Standard Set)
Check out How to Monitor Your Server Health & Performance During a JMeter Load Test guide for detailed installation, configuration and usage instructions.
How to record a script using jmeter for capturing the webservice requests that occurs between two applications ?
Check out https://www.digitalocean.com/community/tutorials/how-to-use-jmeter-to-record-test-scenarios. Specifically, the information on how to set up the proxy for Firefox. You have to make requests through a proxy at 127.0.0.1:8080 or localhost:8080.
Configure both applications or underlying application server, or underlying Java Virtual Machine or underlying operating system to use host, running JMeter as a proxy and it will record all the requests between applications.
You can use Load Testing Mobile Apps. But Made Easy guide as a reference.
For more information on JMeter Proxy Server configuration see:
HTTP(S) Test Script Recorder User Manual Entry
JMeter Proxy Step by Step PDF guide
I am using 'jp#gc - PerfMon Metrics Collector' Lister for this and as you know it requires 'ServerAgent' running on the connecting server.
Step by step instruction would be very helpful.
And also, if anyone knows of any better alternatives to monitor the servers using jmeter then please share with me, it would be a great help.
You can follow the below Steps:
Download ServerAgent2.2.1.zip file(URL: http://jmeter-plugins.org/downloads/all/)
Unzip and Paste the folder in the Machine where Server is hosted.
Run startAgent.sh(Linux) and startAgent.bat(Windows) in the Server Machine.
Get the Server IP and add the same in the Jmeter Properties File.
remote_hosts=
Add the (Perfmon metrics collector)Listener in the Test Plan.
Host/IP: Add the Server Host/IP
Port: By default 4444
Metrics to be collected: What metric you want to collect.
