How to setup delay in jmeter each user Thread Group.
I am trying to run my script Thread group (users) 10,20,30 and 40 and having a delay of 2 min each in them.
How to setup these things in jmeter?
If you want to test your application with 10 users and each user will come after 2 minute delay than pass ramp up as 1200 sec in thread group
The best controller is "jp#gc - Stepping Thread Group". Why it's the best one is, If you use JMeter "Thread Group", we need to change the "Ramp-Up Period" depending on the Threads.
10 User, wee need "Ramp-Up Period" as 20 (1 users for 2 seconds =20/10) to meet you requirements .
20 user, wee need "Ramp-Up Period" as 40 (1 users for 2 seconds =40/20) to meet you requirements .
........etc
If you use "jp#gc - Stepping Thread Group" , we no need to change the "Ramp-Up Period" depending on Thread count.
Just mention "Next, add" :1 threads every 2 seconds,"jp#gc - Stepping Thread Group" will take care Ramp-up irrespective of Thread Count.
You can use Stepping Thread to make your load testing, which helps you to simulate as an apllication used in real time
Just add Constant Timer to your thread group. That's how it is described: "If you want to have each thread pause for the same amount of time between requests, use this timer.".
And if you want to reproduce a special case when you run 30 threads then make a break for 2 mins before next 40 users, then enable "Run thread groups consecutively" option in your test plan settings (top-level element) and add thread with only constant timer between them.
For example if you want to test 40 uesr test with rampup of 10 users.
Each user will take 2 min to rampup. We can use following configuration.

When I'm using the original JMeter Thread Groups and set 10 threads (users), it fires 10 external HTTP calls.
When I changed it to Ultimate Thread Groups (UTG) and set the following attributes...
Start Threads Count = 10
Initial Delay = 0
Startup Time = 60
Hold Load For = 30
Shutdown Time = 10
...it fires thousands of external HTTP calls. Even the Stepping Thread Groups (STG) and Concurrency Thread Groups (CTG) also behave the same as UTG.
Why this happens when using non-original JMeter thread groups? I'm looking for ways to create 10 users that create 1 external HTTP call each (means 10 in total for the whole test plan) using UTG, STG or CTG but I don't really understand why this happens.

Your scenario results in:
On 5th second of the test 1st virtual users starts
Within next 55 seconds remaining 9 virtual users start
10 users are active for 30 seconds
Then each 1 second each 1 virtual user is being shut down
You're seeing much more than 10 requests because once virtual user is kicked off it starts executing Samplers as fast as it can and the actual number of executed Samplers will mostly depend on your application response time. Check out What is the Relationship Between Users and Hits Per Second? for more comprehensive explanation.
If your goal is to execute 10 requests in 1 minute 40 seconds you need to use Constant Throughput Timer or Precise Throughput Timer or Throughput Shaping Timer in order to limit JMeter to send 1 request per each 10 seconds.
I want to send 100 users in 5 seconds and my loop count is 1, but i want to add delay time of 10 seconds after 50 users then remaining 50 users will hit.
Please help me with some suggestions.
You Can use Stepping Thread Group to perform the action required. By Configuring the steps according to your requirement.
Your requirements are mutually exclusive, first you're talking about 5 seconds and then you need 10 seconds delay which brings us to at least 15 seconds plus your application response time.
The easiest option would be going for Concurrency Thread Group or Ultimate Thread Group where you can easily set up whatever workload you want.
Alternatively you can go for the:
Flow Control Action sampler - to introduce the 10-seconds delay
Synchronizing Timer - to act as a "rendezvous" point for the virtual users
Hi i want to run a performance test in which i want to load say 10 users in first second and wait for 2 minutes then load next 10 set of users and again wait for 2 minutes then again 10 users in the same Test plan is it possible
For this purpose "Stepping Thread Group" is the thing you need. And to fix or control the number of samples to execute you can use "Constant Throughput Timer".
Constant Throughput Timer will let you control the flow of requests to be sent."Stepping Thread Group" or default "Thread Group" only control the way the users or threads will be generated.It doesn't control the rate of requests to be hit your application.So for this purpose, you could use "Constant Throughput Timer" to control your requests per second.
For further detail, you could go through JMeter documentation.
http://jmeter.apache.org/usermanual/component_reference.html#Constant_Throughput_Timer
If you are using JMeter, then Stepping Thread Group is what you are looking for.
Features of Stepping thread group are :
1. preview graph showing estimated load
2. initial thread group delay to combine several thread group activities
3. increase load by portions of threads (users) with ramp-up period
4. configurable hold time after all threads started
5. decrease load by portions
Following screenshot shows Stepping Thread Group set to generate load increasing by 10 users each 2 minutes:
Stepping Thread group
If you plan to increase your user/thread at a constant rate, the Stepping Thread Group helps. You can read more about it at :
http://jmeter-plugins.org/wiki/SteppingThreadGroup/
But if you plan to increase your load at a non-constant rate, for example, if your plan is -- start 10 threads in first 5 seconds, wait for 10 secs and start 5 threads, wait for 15 more secs and start 15 threads , then you can use Ultimate Thread Group.
I won't write more about Ultimate Thread Group, since I will limit myself to the question asked. If you are more interested about it, you can read it over at JMeter Plugins site.
I have to test ramping up 1 user every minute for 10 minutes and then then ramping up 20 users ever minutes for next 10 minutes with jmeter. I tried to search on internet, seems like I need to use ultimate thread? If so can someone please give me an example of above scenario?
You can use multiple regular thread groups and in Test Plan,you can select Run thread Group consecutively.
Ultimate Thread plugin allows fine grained control of user threads. It will certainly achieve the concurrency pattern you're looking for. You can also start a thread group delayed with just out-of-the-box Jmeter though:
Use 2 thread groups, and set the required ramp up rates for each thread group. Since you need the second thread group to kick in 10 minutes after the test starts, add a startup delay of 600 seconds.
The relevant jmeter documentation is in Section 4.1 here:
Version 1.9 introduces a test run scheduler. Click the checkbox at the bottom of the Thread Group panel to reveal extra fields in which you can enter the start and end times of the run. When the test is started, JMeter will wait if necessary until the start-time has been reached. At the end of each cycle, JMeter checks if the end-time has been reached, and if so, the run is stopped, otherwise the test is allowed to continue until the iteration limit is reached.
Alternatively, one can use the relative delay and duration fields. Note that delay overrides start-time, and duration over-rides end-time.
It is possible to do with 1 ultimate thread group.
Your setup should be as given below. You did not mention the test duration. I assumed it as 3600 seconds.
1st Row : We will have 10 threads in 600 seconds by starting a thread every min.
2nd Row: We will have additional 200 threads (ignoring the first 10 threads), in the next 600 seconds by starting 20 threads every 1 min.
We need a wait for 600 seconds in the second row which is update in Initial Delay field for the first row to complete.
I have issue with setting ramp-up in jmeter.
My test scenario described below.
There are 3 thread groups:
Thread Group1 - 2 Users - Ramp up 10
Thread Group2 - 3 users - Ramp up 15
Thread Group3 - 5 users - Ramp up 25
Problem i'm facing with above scenario is the following.
First user of all the thread groups is kicked off at a same time.
But i don't want like that, i want the following:
In first 10 seconds, 2 users of first thread group should kick off.
After 10 seconds to the test, thread group 2 should kick off their users.
After 25 seconds to the test, third group should kick off their users.
I have seen one option in Jmeter that "Run thread groups consecutively" but if i set that thread group 2 will never start until thread group1 users should complete their requests execution.
jMeter Plugins' Ultimate thread group and Stepping thread group give you far more control over threads.
Add a startup delay to second and third thread group:
http://jmeter.apache.org/usermanual/component_reference.html#Thread_Group
This should do the job.
You can put anything in Start Time and End Time as these will be overriden by startup delay and duration.
Also note:
Start Time If the scheduler checkbox is selected, one can choose an absolute
start time. When you start your test, JMeter will wait until the specified start time
to begin testing. Note : The Startup Delay field over-rides this - see below.
Note particularly:
