RE: concurrent user: understanding help please
Hi,
To achieve the 100 concurrent users login+search test as advised below, how many hours and Loop I suppose to run the test.
Is there any formula to calculate the no. of hours must be run, to achieve nnn number of concurrent test?
Thanks in advance
Ambs

Probably not.
Although JMeter runs the threads concurrently, with a loop count of 1
it's possible that the first threads to start will finish before the
last thread gets going.
A "burst" test like this does not have a chance to reach a steady state.
You should make sure the test runs for longer so that everything can
settle down.

As above.

What has this got to do with the previous e-mails in this thread?
I'm confused.
When asking a new question, please start a new thread with a new
subject (i.e. don't reply to an existing thread, create a new mail and
send that).

RE: concurrent user: understanding help please
Posted by "Hembha, Ambanna" <am...@logica.com>.
Hi sebb,
-> One thread group1
-> No.of threads : 100
-> Rampup period: 1
-> Loop Count: 1
-> read the login and password from CVS file send a HTTP Post
-> HTTP URL Re-writing Modifier to store the session-id
-> request to login server verify login the result with response
-> read the "search" data from CSV file
-> assertion to verify "search" and verify the searched data
-> store results in CVS file
I'm unable to "search" with same session id ? (I'm not using cookies)
How do I Pass the stored session id - to test "search" feature to validate the response time.?
Thanks
Ambs

RE: concurrent user: understanding help please
Posted by "Hembha, Ambanna" <am...@logica.com>.
Hi all,
I'm able to configure "simple Data Writer" and writing to csv file.
I have checked "save column names (CSV)", it not saving a coloumn names, but it has all the data whatever I have configured!
how do I write "Summary Report" items: Label, Samples, Average, Min, Max, Std.div, Error%, throughput, KB/sec, Average bytes to CSV file
it could in either window or Linux
thanks
ambs

http://jakarta.apache.org/jmeter/usermanual/listeners.html#sample_configuration
in the gui element, you set the file you want the information to be written to.
you make the configurations you see in the link above (uncheck "Save
as XML" so you save as CSV). also, check "save column names (CSV)" -
you will have names for each column so you can read it / edit etc.
a jtl file will be generated, but it has CSV content. you can load
this file later (in most listeners) and check out the results again.
read more for further detalis:

RE: concurrent user: understanding help please
Posted by "Hembha, Ambanna" <am...@logica.com>.
I'm able to configure "simple Data Writer" and writing to csv file.
I have checked "save column names (CSV)", it not saving a coloumn names, but it has all the data whatever I have configured!
how do I write "Summary Report" items: Label, Samples, Average, Min, Max, Std.div, Error%, throughput, KB/sec, Average bytes to CSV file
thanks

http://jakarta.apache.org/jmeter/usermanual/listeners.html#sample_configuration
in the gui element, you set the file you want the information to be written to.
you make the configurations you see in the link above (uncheck "Save
as XML" so you save as CSV). also, check "save column names (CSV)" -
you will have names for each column so you can read it / edit etc.
a jtl file will be generated, but it has CSV content. you can load
this file later (in most listeners) and check out the results again.

RE: concurrent user: understanding help please
Posted by "Hembha, Ambanna" <am...@logica.com>.
Hi,
Thanks sebb & Deepak
I have configured single threadgroup->200 threads test concurrent user test and writing summary report to CSV file.
But I'm unable to see the details what I have expected
It is not printing in the file
Label, Samples, Average, Min, Max, Std.div, Error%, throughput, KB/sec, Average bytes
Could you advise me please.
Thanks

It's important that the test runs for long enough. That way, any
startup delays are less significant.

This is because the response data has to be sent back to the master JMeter.
There are options which can mitigate some of the problems, but the
master node (or its network interface) can become a bottle-neck.

Whether running master-slave or independently, you should make sure
that the various host system clocks are synchronised. If you cannot
arrange that, ensure that you record the time variations so you can
make allowances later if necessary.

Re: concurrent user: understanding help please
Posted by Deepak Shetty <sh...@gmail.com>.
Concurrent user test = Any test with > 1 threads. the longer you can keep
the test running the more likely it is that you will be able to test the
behavior under concurrency accurately. e.g. Running 100 threads with the
test repeated say 1000 times is better than Running 100 threads with the
test repeated once or ten times.
Distributed test = when you need to generate large amount of load that
cannot be generated using a single jmeter client . You run one Jmeter as a
'master' and the rest as slaves. The consensus seems to be thats its better
to run different Jmeter instances and then combine the results rather than a
distributed JMeter test. so if you want to say generate 1000 concurrent
users and you can say generate 250 users per jmeter client (before the
client itself becomes a bottleneck), then you'd run 4 different JMeter
clients on 4 different machines.

Hi,
Jmeter Distributed testing; will be used for concurrent user test ?

Hi,
To achieve the 100 concurrent users login+search test as advised below, how many hours and Loop I suppose to run the test.
Is there any formula to calculate the no. of hours must be run, to achieve nnn number of concurrent test?
Thanks in advance

Probably not.
Although JMeter runs the threads concurrently, with a loop count of 1
it's possible that the first threads to start will finish before the
last thread gets going.
A "burst" test like this does not have a chance to reach a steady state.
You should make sure the test runs for longer so that everything can
settle down.

Trial and error. Try different combination of parameters and see for
your test plan what happens, that is how you find out this.

It won't take hours, set thread loops to 1000 for example, see what
happens, it should reach 100 concurrent in a few minutes of the start.

I don't think there is a way to answer your question because it is too
general, vague.
