Re: Jmeter Throughput Calculation Concern - Native Dashboard Report

[Sergio Boso]

HI Prateek

in this context, the (total time) is the total time used for whole test, from the beginning of the first request until the end of 
the last one.

Resending with more details...

Hi Team,
Need help in understanding the Throughput Calculation in Jmeter Native  Dashboard Report. I'm considering the logic Throughput = 
(number of requests) / (total time). Here for total time, I'm taking Avg Response time of requests.
ie. if requests fired are 100 ( row#2 in screenshot) and Avg response time is 26100 ms ; then I'm calculating -> 100 /26100 in ms 
and then multiplying outcome with 1000 to get in sec ; then further multiplying with 60 to measure it in mins but not getting the  
actual result 2.11 mentioned in report.

Please help me in understanding this calculation.
Thanks,

Re: Run code block only once with JSR223

Hi Alexandre,


never tried this, but I think you can set property objects.
Have a look at
https://jmeter.apache.org/api/org/apache/jmeter/testelement/property/ObjectProperty.html

You should be able to get and set properties.
Let me know if this is successful!

Another possibility would be to convert it to base64

  String b64Request = Base64.mimeEncoder.encodeToString(x)

and send that value with a content-transfer-encoding header set to "base64".

Hi,

I am trying to implement a Jmeter load test for an OCSP responder, and I found 
this page, but haven't been able to get it working:

https://www.blazemeter.com/blog/how-load-test-ocsp-jmeter/

- The first problem that I ran into is where it says "2. Download the public key infrastructure and provider 
".  The link for the "provider" works and allows me to download "bcprov-jdk15on-156.jar", but 
I am not sure what the "the public key infrastructure" is supposed to download?

I think that the "public key infrastructure" means your certificates. If
you download the bouncycastle provider, you probably should take the
newest version of it: https://bouncycastle.org/latest_releases.html

- Also, for the HTTP Request element, it says "The URL of the responder is defined in the 
variable section of the script.", but I am not sure what it is referring to when it says 
"the variable section of the script"?

I guess that the "user defined variables" table on the test plan (root)
element is meant. But on the other hand, the text misses to add a
variable reference on the http sampler (my guess is, that it is hidden
in the http defaults element, that are not described further in the
text), so you are free to add your URL to the http sampler yourself.

And now to a few things you haven't asked :)

* Use groovy instead of beanshell whenever possible.

* Don't use ${...} inside JSR223 or other Shell Samplers. Use
vars.get("...") instead

* Instead of

     Failure = false;
     if (oResp.getStatus() != 0) {
         Failure = true;

     }

  you could use

     Failure = oResp.getStatus() != 0;

or if you feel groovy: Failure = oResp.status != 0



Is anyone familiar with this test plan, and gotten it working?

Note, that I have no OCSP server and thus have not tried to get it
really working.

Felix

Re: Latency x Requests Received

[Sergio Boso]

Hi,

yes it is normal, and this seems confusing at the beginning fro most.
It depends very much on how you design the test, the number of virtual user etc.
IF you do not use times, THEN each VU issues a request as soon as the previous 
one is finished.
So, when response times increase, the throughput drops.
For example, if a request takes 1 second, one VU  will issue 60 request per 
minute.
When a request takes 2 second, one VU will issue 30 request per minute. So you 
have to increase the number of VU to compensate.

IN order to overcome this problem, the best option IMHO is to use a "Constant 
Throughput Timer".
This allows you to make the VU wait and not to exceed a specified throughput.
So in the example above, if you insert a time limiting the throughput to 30 op 
/s, you will not exceed this throughput.
Even if the actual request will take 0.5, or 1 or 1.8 seconds, the throughput 
will not change.
You can adjust the number of VU in order to obtain the desired load.
Obviously, if the request takes more than 2 seconds, , the throughput will drop.

Good afternoon,

I have a question that can be simple for most.

I'm running some tests on a cloud computing with OpenStack.

When network latency increases, the number of HTTP requests met decreases. Is 
this normal behavior?

I figured that the number of HTTP requests would remain the same as when latency was low, since HTTP requests are generated 
regardless of response time.


Can anyone explain this behavior?

Thank you!

Hi,

IMHO, scaling depends on a lot of factors.
Some of them are pretty difficult to predict in advance, but I will
include:
- size and complexity of the request and response (do you retrieve
embedded objects? How many threads?)
Generally speaking,  REST interfaces are lighter than complex web pages
- type and complexity of assertion applied on responses
- complexity of the script: some samplers can be heavier than expected
(e.g. OS sampler)
- amount of data to use (CSV files)

I suggest you to do some test with your script on a single slave
configuration and check you mileage.
That said, I managed a test bed where each slave machine simulated 2200
users, with constant throughput timer at 30seconds.
JVM had 4 G Bytes and 4 fast speed core (AWS infrastructure).
There was even room for more load.
Some key factors you have to keep under control are:
- bandwidth toward the system-under-test
- bandwidth toward the master (result data)
- amount of RAM for the JVM and GC configuration.

Re: Load I can generate?

[Sergio Boso]

Hi,

IMHO, scaling depends on a lot of factors.
Some of them are pretty difficult to predict in advance, but I will include:
- size and complexity of the request and response (do you retrieve embedded 
objects? How many threads?)
   Generally speaking,  REST interfaces are lighter than complex web pages
- type and complexity of assertion applied on responses
- complexity of the script: some samplers can be heavier than expected (e.g. OS 
sampler)
- amount of data to use (CSV files)

I suggest you to do some test with your script on a single slave configuration 
and check you mileage.
That said, I managed a test bed where each slave machine simulated 2200 users, 
with constant throughput timer at 30seconds.
JVM had 4 G Bytes and 4 fast speed core (AWS infrastructure).
There was even room for more load.
Some key factors you have to keep under control are:
- bandwidth toward the system-under-test
- bandwidth toward the master (result data)
- amount of RAM for the JVM and GC configuration.

Hi Sir,
Please find the attachment for scaling environment in Jmeter.

I have mentioned the things as follow.
If we have 4-6 scenario per application with 10-15 samples,
Then we need M\C having configuration of 8 GB RAM, I-3/I-5 processor(2.5-3
GHZ)  for executing approx 1800 VU on slave m\c.

RE: Test Duration

[Sergio Boso]

Hi,
You may want to test the "stepping thread group " from jmeter-plugins.

This allows you to setup the duration of each step and much more.

Re: How would you go about creating a new Thread Group type?

[Sergio Boso]

umber of threads (1000 in my example), and your 100 threads always
restart until there are no loops left to run. Then the longest
period you have where you aren't fully loading the servers is just
the last loop for every thread.



BUT, I am not 100% sure where I would start in the source code. I
have programmed before (a long time ago), but if someone could point
me in the right direction (like, which source files would need to be
modified, and how would I register my new Thread Group as a
different option), I think I could figure it out pretty quickly.

Re: Jmeter test for OTP enter process

[Sergio Boso]

I can see two other workaround.
The simplest is asking your software people to skip OTP checking in Q
environment. This way you enter a fixed OTP.
The second one is use email instead of SMS, that is an option that many SW
have. The cost here is that you have to setup a mailbox for each user,
which can be an heavy task to perform.
The good side is that it is quite easy to use the Jmeter POP /IMAP sampler
and get the data.

Re: Jmeter pausing when running

Hi,
like Sebb already said, definitely try running Jmeter in non GUI  mode.
You should have a command like:
*  jmeter -n -t your_script.jmx*

Re: Remote Testing with different external data files

Is there any way to use different external data files in each remote server 
when doing remote testing? Which mean Server 1 use file 1, Server 2 use file 2 
etc, then client will trigger all servers with same test plan.

I have browsing over the JMeter docs and Wiki, unable to find solutions on how 
to implement this. Basically I need server 1 to use user 1 to 10 to login and 
perform testing, server 2 use user 11 to 20 to login and perform testing, all 
the test scripts are same but just the login users will be different.

I need to simulate 20,000 concurrent users access, distributed to around 40+ 
test PC.

Appreciate any help to save me remote desktop to each test PC and click 1 by 1.

Hi , sure you can, I did this many times.
How ever, if you have so  many system, you may find more effective to have a 
central DB, and have each Jmeter instance ask for usr data.
I found Redis and Redis plugin very effective for this.

A better options could be to use Jmeter plugins with Redis connector.
The random remove operation can fit your case.

This require a central server and some scripting  to load data into Redis

RE: not all 50 http samplers to download file are executed

Hi Charles,

If I remember well, if you check the "save MD5 only", the full data is not
kept in memory.
You can check that data are data correct and you save substantial amount of
memory.
Other approach may involve OS sampler and wget operation.

Re: Plugin to automatically transfer resource files (csvs) from controller to injectors

[Sergio Boso]

Hi
I had same issue, but solved differently by using a central Db with Redis.
I think it is much better approach, more flexible and scalable.
This can support either circular lists ( e.g. user info) and use-only-once
data.

You can use the plugin from Jmeter - plugin ( not so complete anyway) or
develop your own integration, which is quite simple any way.

Regards

Sergio Boso

Hi,

When carrying out performance load testing on JMeter, we often set up a
controller and multiple injectors and use CSV files as data sources. We
then have to manually copy each CSV file to each injector. In cases where
we don't want the same data being used by multiple injectors we also have
to split the csv up into separate files, copy each file to a different
injector etc. It feels like something that we should automate to save time
and avoid human error.

Requirements:
- Automate copying csv files from controller to injects before testing
begins
- No test should begin until all csvs have been copied (to avoid lag for
later injectors)
- The file transfer should be automatically triggered when the test is
started (to avoid human error in forgetting to do it)
- It should be possible to split a CSV between injectors so that lines are
evenly shared.

So my question is: *Is it possible for me to do this purely by writing a
plugin? If so, what kinds of objects would I be looking at creating and
whereabouts in the code is/are the method call(s) into it that I'd be
using?*

Looking at the code in DistributedRunner.start() and
ClientJMeterEngine.runTest(), I can't see any hooks I could use to execute
plugin code after starting the test run but before running other steps.
Unfortunately, using the HashTreeTraversers in ClientJMeterEngine.runTest()
would result in files being transferred on one Injector after testing had
started on another injector, potentially introducing lag between tests.

Any help much appreciated and if this is not currently possible I'll give
the dev list a try!

Many thanks,

Jonathan Mew

Re: Distributed test

[Sergio Boso]

Hi,

as described here:
http://jmeter.apache.org/usermanual/jmeter_distributed_testing_step_by_step.pdf

you must have all computer running on the same VLAN to execute a
distributed testing.
I think you have two options:
- move the master to AWS, on the same VPC
- setup a VPN so that all server are connected on the same network

IMHO, the first one is much ore simple.

Re: Jmeter error: jmeter.samplers.SampleResult: sampleEnd called twice java.lang.Throwable: Invalid call sequence

[Sergio Boso]

Hi Felix,

I finally tested Version r1676403 , (build on April, 28).
It fixes the problem, that now is logged as a protocol error, without any 
exception.

The originating problem was a 307 HTTP return code, with no URL specified in the header, while the sampler had the follow 
redirect  flag set.

These conditions caused the exception, without much details.

The target URL is specified is the payload, but obviously this could be not 
used by Jmeter.

Again, thank you very much for your support.
Regards

Sergio

I think jmeter does not use cache at all. right?

Consider a situation: Web Page is big(many resouces, big pictures. etc) and
network throughput is limitid or not enough.
How to deal this situation?
- in other test tool, such as Loadrunner, don't check ' clear cache in each
iteration' option.
- in jmeter, we should record the samplers exclude resources.

I guess it takes a lot of memory to setup 8 different instances on a single

I'm curious to see if there are other ways to do that.

I believe you have to have all of those IP Addresses configured on your

Mail reader sampler: IMAP statistics

[Sergio Boso]

Hi,

Also on IMAP statistics there is some inconsistency.

Suppose to use IMAP and to set two messages to downloads.

When you run the test, Results tree shows you a sample holding two leaves (one 
for each message).
It looks like it were an HTML page holding 2 different component, which is very 
reasonable.

BUT, if you go to the Aggregate Report and Summary Report you will see  2 
different operations, each with its own time.

IMAP20  904 895 961 820 10130.0 
1.1028398125172318  12.861977012682656
TOTAL   20  904 895 961 820 10130.0 
1.1028398125172318  12.861977012682656


Again, if you save the results to a .jtl file, only one results is saved 
holding the total time (which is the expected behaviour).

Should I open a bug on bugzilla?

best regards

Hi,

I have found an odd behaviour, when reading email with POP protocol.

The Aggregate Report and Summary Report return random numbers for those 
samples.
View Results Tree gives reasonable numbers.
Furthermore, if I write results to a .jtl file, and then I reload them to the 
report, everything is OK.

Using Jruby in Jmeter

[Sergio Boso]

Hi everybody.

I find JavaScript a little bit clumsy, so I did some test with Jruby.

It is very straightforward to use, and relatively fast, after the first 
execution.
However, I had some trouble when running the same routine at the same time 
multiple threads.

So may question is:
- is thee any real world experience in using Jmeter +Jruby?
- Is Jruby really thread-safe? can I use a variable myvar in multiple 
instances?
- What is the behaviour of $myvar (which is a global static variable in 
standard Ruby)?

Thank you in advance

   throughtput= nSample/ dur

The GUI listeners can read result files and generate the report from the file.

The default fields that are saved in the files should be sufficient
for most Listeners apart from Tree View.

Therefore,  is there any limitation of no. of machines to be used in

//I actually went through a scenario with 8+1 machines few months ago.
It was on JM 2.8, I had no particular problem.

One thing I noticed was that the network traffic between slaves and master was very high (really very high) approaching 70-80 
Mbit/s, measured at the master operating system.

So the master should be monitored closedly.

I did not digged deeper , maybe there is some configuration to optimize this

Re: Calculating the throughput (requests/sec) and plot it

[Sergio Boso]

HI

there are few  points here.

1)  Throughput is described clearly here
   http://jmeter.apache.org/usermanual/glossary.html#Throughput


2)  Throughput  is part of Summary Report  and Aggregate report, which in turn 
are part of the standard Jmeter code.
So this question seems appropriate here.

3)  Instead of using Simple Data Writer, you can use the Write result to file configuration. This way, you can also re-read 
the data and visualize them, after the test has been run..
This allows you do do comparison on the same data, Using a simple data writer probably introduces some skew (few msec, but the 
numbers become different)


4) interesting point about Jenkins, as a tool to automate reporting
Is there any pointer/cookbook around?

Thank you

Hi, thanks for the reply. I already corrected that formula, but it still

difference=894 milliseconds

That's wrong as well; you need to subract the first start time from
the last end time.
Or add the last elapsed time to the difference between the two start times.

However, this is all academic, because the Statistical Aggregate
Report is not a standard JMeter listener.
Queries on it need to be sent to the maintainers of the plugin,
whoever that may be.


samples=277
So I tried with: (277/894)*1000=~309 requests/second. But the first
graphic, in the same period, shows a throughput of ~90.

I'm using JMeter client to test the throughtput of a certain workload

test with an increasing number of threads over the time.

I installed the Statistical Aggregate Report JMeter plugin and this was
the result (ignore the Response time line): [image: enter image

At the same time I used the Simple Data Writer listener to write a log
file (JMeter.csv). Then I tried to manually calculate the throughput
for every second of the test.

Each line of JMeter.csv has this format:

timestamp   elaspedtime   responsecode   success   bytes
1385731020607   42200true  325
... ...   ......   ...

The timestamp is referred to the time when the request is made by the
client, and not when the request is served by the server. So I simply
did: *totaltime
= timestamp + elapsedtime*.

That's wrong.

timestamp + elapsedtime = end time *not* total time.

The timestamp is the start time.


In the next step I converted the *totaltime* to a date format, like:
*13:17:01*.

I have more than 14K samples and with Excel I was able to do this

quickly.

Then I counted how many samples there were for each second. Example:

totaltimesamples (requestsServed/second)
13:17:01 204
13:17:02 297
...  ...

When I tried to plot the results I obtained the following graphic:

[image:

As you can notice it is far different from the first graphic.

Given that the first graphic is correct, what is the mistake of my
formula/procedure to calculate the throughput?

Re: CSV file iteration in remote tests

Hi all,

I'm sure that this is a common problem for those using JMeter executions
across several machines. Can't really find any solution to this. So here
goes:

I have a plan that looks something like this:

Test Plan
   |-- Thread Group
  |--CSV Dataset
  |--HTTP Sampler (login)
  |--

If I remotely distribute this all remotes will 1st start with line one of
the CSV file. In my case this will cause locking in the application,
thereby destroying the test. Ideally I'd like to give the CSV file a random
offset for each remote client, so that it would start iterating at various
points in the CSV. This is not quite safe but should give me enough
variance so that the chance of locking would be minimal.
The only way I have found to cope with this is to manually split the CSV file, and copy each of these parts to each remote system, 
so that each system uses its own set of lines.


I'm looking forward to see if there is a better system

hi,
I thinked of a question about how to show the result of a stable test using 
jmeter.
i.e. I plan a test that will run for 24 hours. the purpose is to see if the 
system of being tested can serve with the same service level during a long time.
so, I want to do statistic and get some value(i.e., TPS) of each hour, then 
link the points of 24 values to a line in a diagram to clearly show the user 
that if the system is serving stablely during the test.
Can I do this in Jmeter? I don't know, because I don't know if Jmeter stores 
the time when capturing measurements data. If jmeter doesn't know when it gets 
the measurement data, obviuosly it can't do statitics according to time slice 
(i.e. an hour).

Hi you can easily configure Jmeter to save each sampler into a .jtl file.
This can be done on GUI (configure a listener) or via command line (recommended 
for high volume tests) with -l option.
Then it is also easy to get totals on the whole test, using Summary Listener 
and Aggregate listener.
Calculating statistics by hour can be a little bit tricky, you have to work a 
little bit with Excel or whatever.

Re: Comparing results from two samplers in JMeter

Non knowing much about your application, and its complexity,
I would extract the value from the first sample (using regular expression),
and the use it on the second sampler (you can use regex also inside assertions, 
if needed)
using response assertion.

Your solution is more complicate, it may be useful when regex are not suitable.

In the JMeter API documentation I could not see anything to access another

Re: jmeter memory leak?

[Sergio Boso]

just to add some info, you have to take in account that Jmeter keeps all the sample's result in memory, even i there is no further 
process for it.

So, if you are downloading some large objects (like imaging, SW updates and so 
on), then you can easily go out of memory.

If this is the case, look for the maximum object size run just few threads and increase memory accordingly (HEAP option, in Jmeter 
start script)

Chaityna/Kirk,


For a customer, I wrote a script that allows use of Jmeter scripts to Monitor 
the performances of web applications.
It is generic, so you just have to configure the JMX file you want to test.
The internal logic is a little bit tricky, because you have to take in account of response timing, HTTP response and content 
assertions to set a PASS/ WARN /FAIL response.

Timing can be monitored either or specific pages AND for the overall script.

I found this approach is quite effective on the timings side, but it has weaknesses on the maintenance, as you have to update the 
script while software updates.

Also, it is not that easy to cope with heavy Javascript-automated pages.

For that case, I integrate a browser based approach (I use Watir/ webdriver) 
that can better fulfil the purpose.
In that case, the architecture is similar to WebPageTest.
I'm planning to release my script as OS..

Please contact me privately if you are interested.

best regards
Sergio Boso


Thanks for the inputs.

As far as possible I wanted to keep the assertions only on the client
side to keep the test setup simple. I had originally thought of, as Kirk
suggested, to assert based on the access log timings, but the test setup
will be complicated to get up running and maintaining.

I though it would have been possible to do some kind of assertion,
based on the response time for each request in jMeter, which I
believe is reflection of the server introduced latencies as jMeter not
attempting to render any of it.

Thanks again for your inputs.
By the way I am also investigating the offline webpagetest.

Re: What should we conclude on the basis of Failed Samples?

[Sergio Boso]

This means   that your system as a whole is not able to bear this traffic.

Inspect each element  to find the cause.
On the network side you should consider bandwidth. This could easily
happens if you have many multimedia objects.
Based on this kind of java exception the jmeter server seems to work
properly. However Keep an eye on memory usage.
Finally on SUT side, it seems it is not able to accept new connections.
Look at apache or IIS configuration, it often impose some limit on
connections. If there is a sudden increase on response time, compared tothe
500 users execution, there may be some more generic resource shortage.

Re: Establishing baseline metrics

[Sergio Boso]

 of machines. (We also test a cluster of 2 machines - and measure 
the fall-off in capacity between a 1-member cluster and
2-member cluster, this gives us an idea of how much impact our 'clustering' 
system has on performance as well.) I suppose you could
say that I look at it as if, we measure the 'maximum capacity', and so long as 
the number of users doesn't exceed that - we will
perform OK.

We do run some 'all-encompassing' system tests as well, but those are more for 
'stress' testing than for performance benchmarking.
We are specifically looking for things that start to break-down after hours of 
continuous operation at peak capacity. So we monitor
error logs and look to make sure that we aren't throwing errors while under 
stress.

The number one thing to keep in mind about performance testing is that you have 
to use 'real data'. We actually download our
production database every weekend, and strip out any 'personal information' 
(stuff that we protect in our production environment) by
either nulling it out, or replacing it with bogus data. This allows us to run 
our performance tests against a database that has 100s
of millions of rows of data. Nearly all of our performance 'bugs' have been 
caused by poor data handling in the code (SQL requests
that don't use indices (causing a full table scan), badly formed joins, 
fetching a few rows of data and then looping through them in
the code (when the 'few rows of data' from your 'dev' environment become 
100,000 rows with the production data, this tends to bog
the code down a lot), etc.). So if you are testing with 'faked' data, odds are 
good you will miss a lot of performance issues - no
matter what form of performance testing you use.

I will say that we have served over 130M web pages in 1 month, using only 5 
servers (4 tomcats, and 1 DB server)... Those pages
represented about 10X in GET requests to our servers...

Re: Results ambiguity

[Sergio Boso]

There can be many reason for these results.

- is there any other activity on the system under test?
- is there any other activity on the network, slowing down the measurement?
- is there any other activity on the load generator?

I would run the test at different time of the day, to gather different 
situations.
Also, you can try to check response time when incrementing the loop number:
often, the system is slow at the startup because  it is filling the cache, 
compiling pages etc.
then it become faster.

Re: Aggregate report

[Sergio Boso]

There are many ways,

but the one I would use is to save the thread number  to a file, and use the 
.csv output.

Then you can import to a Excel or Calc Open Office, and filter in/out the data 
you want  do not want, and save again in csv format.
You can also process easily the csv data with grep in order to obtain the same 
result.

The main point is that the data file can be reloaded at any time to calculate 
the reports (either aggregate or summary or graphics etc).

Jmeter stuck with bad application error management

[Sergio Boso]

Hi I'm experiencing a weird behaviour  in Jmeter.

As the application has its own burden of problems, it returns sockets error fro 
time to time.
The point is that Jmeter, instead of recording the error and going on the next sample, gets stuck there forever (no time out is 
applied).

I can stop it manually, reset it and restart it.

Here is the error stack after manually stopping.
have you ever experienced such a behaviour?
Is this already known?

Java the error stack follows

Is there some non-trivial way to access the parameters that were passed in a

Often some regular expression i required.

Re: Use FileToString for 100MB file

[Sergio Boso]

I recently went through a situation where I had to download some 300MB+ files.

In fact, it seems that Jmeter tries to keep the sample result in memory until 
the operation has finished.
I assume that this is done in order to do allow  assertion, content analysis etc, but where very large files are involved, this is a 
real issue.


I made a quick workaround using OS sampler + wget command+ delete file command.
I think that an option to save the sample result to file, would be more 
appropriate.

Most common cause of memory issues in gui are listeners, particularly results

testing your tests, rather than doing your load testing.

AFAIK, in non-gui tests it is likely older HTTP implementations, use v4+.  I 
never get memory issues in CLI tests.

However, 100MB filetostring does not really sound like something I'd want to

Recording HTTPS from iPad

[Sergio Boso]

HI everybody,

I'm working to test a server application that is used from an iPad client.
It is an enterprise app, so everything is encrypted.

I set up Jmeter as a proxy as usual, and I can manage to record the traffic 
from the iPad browser.
When I launch the app, nothing work.

My guess is that the app is not able to manage the exception due to the dummy Jmeter certificate, so the communication does not even 
start.


While we are contacting the app company, I was wondering if there is any 
effective, standard solution to this problem.
Any way to present a standard certificate from Jmeter?
Or, any way to set-up a truly transparent proxy, by setting the jmeter machine 
as a default gateway for the device?
This would require at least to propagate the DNS protocol beside http?

Any suggestion is welcome

thank you and best regards

Hi,
Is your application making transition from HTTP to HTTPS and back to HTTP

hit a secure page you get a secure cookie from the server and stored in cookie 
manager. This secure cookie is not used for HTTP requests. So you should make 
sure to write a beanshell preprocessor which changes the property of secure 
cookie to insecure, so that it will be used in future requests. Have a look at 
the Response header of the first request that hits the sever. You will have a

What kind of protocols it uses with the server?

I found traces of a plugin here:

You may also try to disable the

Re: Where do I find all of these cool settings for the 'properties' files?

[Sergio Boso]

Well,

in release 2.7, they added a very cool property display controller (see the non 
test elements group).
very easy to read..

About setting properties, I'm not sure about the fact that user.properties can overwrite properties set in jmeter.properties. Any 
experiences here?


To compare different versions of the same file, I'm using Winmerge.

Is there a document that distills them all?

BTW, I highly recommend that you put your modifications in the 
'user.properties' file, instead of the 'jmeter.properties' file. The 
jmeter.properties file gets updated with new releases, and it is a pain to 
hand-compare the old version with the new version and move your modifications 
over. It is far easier to use 'user.properties', since it never has any 
settings in it with the releases... Then you can just copy your user.properties 
file over to the new release, and you're ready to go.

try to trigger the regexp with:

select id=xyz name=xyz

and close it with

/select
also, remember to  enable single line mode.
The final expr should be something like:

(?s)select id=xyz name=xyz.*option value=(.*) /select

Re: new __Time function

[Sergio Boso]

Il 15/06/2012 10:13, D G ha scritto:

This all started as 'now + n days', so the __timeAdd methods works on
a now + something manner.

New proposal:
__timeAdd(format, number*, m|h|d|w|M|y**, parseString, parseFormat, variable)
where parseString is the string to be parsed into a date object and
ParseFormat is the format of the string to be parsed.

I use to do that kind of things in Javascript, in a BSF pre or post processor.

It takes just few lines of code, according to what you want to do.

I'm keen to understand what would be the advantages of an integrated solution.

regards
Sergio

My criticism would be the growing number of (optional) parameters but
it's too easy to lose __Functions somewhere in a test. Don't like
using two functions to accomplish a task :)
Another would be requiring some knowledge of how Java parses data.
Though that should be reasonably trivial to learn for most strings.

Also, it would be quite easy to allow parseString to accept a
float/epoch time and work with that.

Thoughts?

Daniel

Hi Shaba,

I am trying to extract that for each login and pass it on wherever it is
repeated in further samples.

these value go back and forth between the browser and the server,
and MAY change each time, so you have to extract them each time.
In my experience you have to:
- capture the user interaction (using fiddler or httpwatch)
- find where these variable are passed and test your reg exp on them
- then you can bring the reg exp to jmeter environment

regards


I tried all combinations as suggested by others here, but still no use.

Pls suggest the best

Using Jmeter with Microsoft Dynamics CRM 4.0: wrptoken management

[Sergio Boso]

Hi everybody,

I'm working on testing an application based on MSFT Dynamics CRM.

Most of the operations went well, but there is a web service that fails, and 
says:
 WRPCTokenState=Invalid...

Digging a little deeper, I saw that on this specific WS, the token sent has a 
value that has never been sent by the server before:
in other words, it seems that the token is calculated by the browser.

Do you have any experience about that? any suggestion or workaround?

Thank you in advance

Re: Access log entries, results log entries, and expected RPS total count not adding up

[Sergio Boso]

Hi,
I'm not sure about your configuration, particularly about the log file that was 
read once..
It would be nice to have some more details about that.

However, you should be aware that, if your system system under test cannot bear 15 TPS, the whole test will be slower thus returning 
less transaction in 6 hours.

So, in this case, the Constant Throughput Timer, cannot make your system faster.

You can check if this is the case, just by lowering the load (e.g to 5 tps) and adjust your math: you should discover that the 
numbers are ok.

regards

I would expect my results log to have either a.) 194K entries because
the

reading the same log over and over to fulfill the demands of the

shaping timer.

However, my result log is 235K which doesn't mean anything to me. Can
someone elucidate how this works?

Re: JMeter agents in Amazon

Il 04/05/2012 16:35, Kohn, Rodolfo ha scritto:

Hello,
I'm running JMeter for distributed load test in Amazon.
When I run all components in the same AWS region, everything works OK because 
each host can be addressed by its private IP address. In AWS hosts are assigned 
a private IP address and a public IP address.

However, I found some problems when trying to execute with agents in different 
regions:

1- JMeter client sends its IP address to the agent in a RMI message. The 
problem is that the IP address identified by the JMeter client is the private 
IP, while I need it to send the public IP.

2- JMeter agent communicates back with the client through another port.

My questions are:

1- Is there a possibility to indicate JMeter client to send a different IP 
address? It could be configured.

yes,
You have to use http client (4.0 is better).

IN the properties file , look for
# Define the local host address to be used for multi-homed hosts
httpclient.localaddress=1.2.3.4



2- Is there a way to indicate the JMeter client port for the agent to 
communicate back?

yes, in .properties file go to
# Remote hosts and RMI configuration

and set
remote_hosts=hostname:portname, hostname:portname,...

default is (localhost:1099)


Thanks,
Rodolfo
