I am doing spike test using Apache JMeter.
My test scenario is to create booking on a website.
I am using sync timer to generate spike at the create booking.
How can i verify spike is actually generated after test is finished ?
to validate a spike in requests, you need to add a listener that will plot all the requests hitting your server over time.
there's a plugin that can help you do it:
https://jmeter-plugins.org/wiki/TransactionsPerSecond/
I suggest you to use custom thread group instead of using the default thread group. Please check JMeter Plugins website.
Stepping Thread Group
Ultimate Thread Group
Concurrency Thread Group
Arrivals Thread Group
Free-Form Arrivals Thread Group
There are multiple ways to validate the load.
You can check in APM tool if you are using any.
You can plot multiple graphs such as Hits Per Second, Response Time
over time, Response Codes, Bytes Throughput, Connect Time and
Latency and correlate with the time.

I have a requirement to create simple Burst test in Jmeter:
10 requests-> 20 requests -> 30 requests
On single worker mode.
Throughput 20ms
Anticipated response time : <=200ms
How can we achieve this with Jmeter without using parallel threads?
I am looking for a simple solution.
Thanks a lot
Add plugin
Ultimate Thread Group to JMeter
Add Ultimate Thread Group component with settings of 3 rows
Set Start Threads Count 10,20 and 30
Use different start times so requests batch will be executed in different times
"Ultimate" means there will be no need in further Thread Group plugins. The features that everyone needed in JMeter and they finally available:
infinite number of schedule record
separate ramp-up time, shutdown time, flight time for each schedule record
and, of course, trustworthy load preview graph
Consider using Throughput Shaping Timer and Concurrency Thread Group combination which provides flexible way of defining load patterns:
They can be connected together using Feedback Function so JMeter will be able to kick off more threads in order to reach the desired throughput (number of requests per second) if current amount is not enough.
Both can be installed using JMeter Plugins Manager:
I have multiple thread groups in my jmeter test plan, each thread group represents a use case of my application.
I am also using webdriver for these scenarios.
So I am trying to find out what is the average time that each use is taking. which is basically the thread group avg time.
Any thoughts how I can do this.
You can add a Transaction Controller at the top level for your Thread Group(s) and make all Samplers children of this Transaction Controller.
This way you will have cumulative information in JMeter Listeners
or in the HTML Reporting Dashboard
I am quite new to jmeter and try to do a performance test of my application. I want to generate 100 request per second scenario however my server takes 3-4 secs to respond to every request. I am running my test for 1 mins which means number of requests fired should be 60k within the time span. However jmeter actually waits for the response before it sends next request. Which is not what I am looking for.
How can I make sure that jmeter sends a new requests every second with 100 req/sec without waiting for the response so that the number of requests fired per min is 60k.
I am trying to use constant throughput timer with 60k as request per min, however that is not helping. Here is my test screenshot.
EDIT
I have done like this
And Throughput shaping timer being as
So ideally I should get number of samples as 3000?, still not getting that.
Make sure you provide enough threads (virtual users) under Thread Group, "vanilla" JMeter won't kick off any extra threads if actual throughput is less than target one you specify in the Constant Throughput Timer.
Another solution would be using Concurrency Thread Group along with the Throughput Shaping Timer. They can be tied together via feedback loop so if you use these test elements JMeter will start more threads if the current amount won't be enough to reach the desired requests per second rate.
You can install both using JMeter Plugins Manager
My suggestion is to consider using the Arrivals Thread Group. This TG will allow you to configure the desire average throughput (ATP); the TG will instantiate the required threads needed to achieve the ATP goal.
i am new to Load testing and would like configure my jmeter setting for the following requirement below. My understanding is Theard are different from request per second. If so what will be values in thread group for the below requirement.
"Initial load 20 request/second, increase load with 100 request/second for each minute.
Perform load test until we see an increase in latency "
You should put something very high into Thread Group and use one of the following approaches to define your load pattern:
Constant Throughput Timer - it comes bundled with JMeter
Throughput Shaping Timer or Concurrency Thread Group- available via JMeter Plugins project
In order to automatically stop the test when latency exceeds threshold you can use AutoStop Listener, again it comes with JMeter Plugins.
In general latency is networking related metric so even if your application is slow as a snail you can have low or even zero latency so I would recommend considering response time and/or transactions per second metrics as well.
I'm currently using Apache JMeter to run load tests on the REST interfaces of my backend application. The test plan currently uses two thread groups and runs those in loops. Both thread groups are sending particular REST requests at a certain throughput using a constant throughput timer. The first thread group randomly picks one of several different REST requests, while the other uses one fixed REST request.
With this setup, I'm able to fire load to my application at a constant throughput. Now, I would like to simulate that over a day/night load profile, given that from e.g. 8:00 am to 5:00 pm the load is at a certain constant throughput, while in the rest of the time (the night), the load drops to a lower throughput or even stops entirely. Then at 8:00 am the next morning, it rises again.
Do you guys know if such a load profile can be simulated using Apache JMeter? Do you also know, which constructs could be used to setup something like that?
Thanks for any hint.
Regards
Timo
You can consider switching to Throughput Shaping Timer which seems to be exactly what you're looking for. See Special Property Processing chapter for the "load profiles" bit.
You can get Throughput Shaping Timer element via JMeter Plugins Manager
