Re: HTTP Request sampler other means of sending data
The browser is not sending in a name/value pair post. There is an ActiveX object
created by javascript that sends in post method but just the data. I think it uses
xml http. I'm discovering this as I go. A sample javascript to invoke this may look
like
var objHTTP = new
ActiveXObject(Microsoft.XMLHTTP);objHTTP.Open('POST','servletname',false);
objHTTP.setRequestHeader(Content-type,text/plain;
charset=UTF-8);objHTTP.Send(148/GetTableEntryList/8/);
Since I think it's using xml http, looks like I have to write a new sampler. But the
soap-xml request looks like something I can use or build off of.

in a normal is it even possible to send just
148/GetTableEntryList/8/ without a parameter name? I didn't think
it was possible.
if it's a normal name/value pair, you should be able to access it with
the normal request parameter objects. if not, I'm totally lost as to
exactly what you're trying to achieve.

Re: jmeter memory consumption
Hi Peter, I have been using Segue Silk Performer in the past and was always able to get a load of 500 on a similar machine described below with good results. I am actually trying to replace Silk Performer with JMeter. I am trying to see how much load one Jmeter client can handle. I am planning to use several clients as you suggested but there are only so many machines available. My plan is to get up to a 5000 virtual user load going. If your approximation of 75 virtual users per machine is used, that would yield about 67 client machines to generate such a load! I suppose no one has used Jmeter to the extent that I am planning. mabel Peter Lin [EMAIL PROTECTED] wrote: to my knowledge, even if you use a commercial product like mercury.

RE: jmeter memory consumption
I will try running without any listeners and see if it makes a big difference. I had planned to have several clients generating load and these wouldn't have listeners and then a client with one user will have the listener. Well, I did try non-gui mode but some threads kept hanging. It didn't happen with gui mode though. Do you have plans to improve the jmeter performance? Everything else about Jmeter is great. This is the only real blocker I have come across so far. thanks, mabel BAZLEY, Sebastian [EMAIL PROTECTED] wrote: It would be useful to know if it is as hungry without the Aggregate Listeners.

RE: Hanging threads in non-GUI mode
Hmm, didn't know there were two options. Looking at the June 12th nightly build I'm using, the Sampler gives HTTP Request and HTTPRequest HTTP Client(ALPHA) . I am using the default http sampler because that is what the Proxy recorder uses. I have been using this since version 1.9. All requests use keep alive. Just one or two use redirect, but that is only done once per user (done for login). To answer Mike's questions: 1. Are you using any timers? 250 virtual users with no delays is a hell of a load Yes. Between controllers (there are 2 that are repeated for 45 minutes), I have uniform random timer between 5 to 15 seconds. Then I have some user think time between opening menus that are uniform random between 1.5 to 5 seconds. And some uniform random timers between 1 to 4 seconds for waiting to click on a link. Then there are some requests that are performed without timers. 2. What kind of average response times are you getting from these requests? The overall average total is 33 seconds. Some pages have it set to retrieve embedded resources. 3. What order of magnitude are the responses? 10's of bytes? 100's? 1000's? 10's of KB? The average request response size is 42KB. The minimum response time is less than 1KB The largest response is 394KB which happens when opening a page. 4. What kind of dynamic elements do you have in the test plan? Are you doing a lot of regex parsing of response data? Out of 44 HTTP Requests, I have 7 regex parsing and 14 Assertions There are 6 aggregate listeners. Running without the listeners did not make a difference.

Machine configuration used for JMeter
Hi JMeter Users, I would like to solicit feedback of what machine specifications you're using to successfully load one Jmeter client with *reasonable* response times. This would greatly help out new users on setting up a load. What is the OS, CPU type, Memory of the machine? What is the JMeter JVM configuration that you used? What is the Jmeter load (# of virtual users per machine)? Did you run on non-gui mode? Turned off all listeners? Leaving just aggregate listener? What is the general structure of your JMeter script? How long did you have the script run to be successful? Thanks! - Do you Yahoo!? Take Yahoo! Mail with you! Get it on your mobile phone.

clarification on remote testing
I am confused as to the setup of distributed testing. I have read the docs on how to set up but the use of server vs. client seems backwards to me. I got the connections going but I'm not really understanding how it works. According to the docs, or how I am reading into them, there are many JMeters running in server mode, therefore, many RMI registries running on separate machines. For example, S1, S2, S3 are machines running Jmeter server. I am thinking there is no GUI or batch jmeter running at all, just the jmeter server. Then according to the docs, there is only one client controller, which uses the GUI to control. I'll call this machine C1. In C1's jmeter properties file, it has S1, S2, and S3 listed as the remote_hosts values. Then if C1's test plan has 100 thread users and I select Run/RemoteStartAll, it will start the remote testing on all the server machines. The parts where I am confused: 1. The use of server and client is backwards to me. Shouldn't there only be one server and many clients? And the server should be the controller. 2. How on C1, if I specified 100 thread users, does it distribute among the 3 server machines? Is it always divided evenly? Can I control the distribution? 3. Are the results gathering done while the load test is running? I read in previous archived messages that there is a hold_samples property that you can set to indicate all results should be written at the end of the test. However, I don't see such a property setting in jmeter.properties. Then is the gathering of results done on C1? 4. Since C1 is the controller, it is not sending HTTP Requests, only facilitating and from #3, gathering results? Thanks for the clarification! mabel __ Do you Yahoo!? Friends. Fun.

Re: clarification on remote testing
Thanks for the clarification. So do you recommend us to even use remote testing if you think it's ugh? I just noticed that global counters are not shared among the servers. Each server has it's own counter which starts at the same values as the other servers. That sucks. :-( --- Michael Stover [EMAIL PROTECTED] wrote: JMeter remote testing - ugh. That's my assessment of the current state of this functionality. Anyway, to answer your questions: 1. In this case, client and server are used in a sense such that you, the user, sits and does work on the client, which then sends requests to the servers. Think of an email client that polls multiple email server for messages. The request the client sends is do this test, and then the sample results roll in. 2. The client sends the whole test to every server. So, if the test specifies 100 threads, each server runs 100 threads. I think you can figure out the degree of control you have given that... 3.

Re: How throughput is calculated
The whole point of me trying to verify the JMeter throughput
calculations is to use the same formula in Excel or some other program.
If what you say below is true, then that is not what I'm seeing. I may
be looking at the wrong code but this is what I'm seeing. I am using
version 2.0 and looking at that source code:
In SampleResult.java, the constructor is called when a line of results
is read from the jtl file. If properties not found, default is end
timestamp according to code.
public SampleResult(long stamp, long elapsed)
{
// Maintain the timestamp relationships
if (startTimeStamp)
{
setTimes(stamp, stamp + elapsed);
}
else
{
setTimes(stamp - elapsed, stamp);
}
}
Then a SampleResult object is added to the RunningSample object for
that request type.
public synchronized void addSample(SampleResult res)
{
long aTimeInMillis = res.getTime();
boolean aSuccessFlag = res.isSuccessful();
counter++;
long startTime = res.getTimeStamp() - aTimeInMillis;
if (firstTime startTime)
{
// this is our first sample, set the start time to current
// timestamp
firstTime = startTime;
}
if(lastTime res.getTimeStamp())
{
lastTime = res.getTimeStamp();
}
runningSum += aTimeInMillis;
if (aTimeInMillis max)
{
max = aTimeInMillis;
}
if (aTimeInMillis min)
{
min = aTimeInMillis;
}
if (!aSuccessFlag)
{
errorCount++;
}
}
In this statement
long startTime = res.getTimeStamp() - aTimeInMillis;
The code is assuming that the timestamp is always the end timestamp.
But the timestamp can be a start and doing the elapsed time subtraction
is setting the start timestamp to an earlier start. Am I wrong? So in
my original email, this is the behavior I am seeing for the start time.

I am a bit confused as to how JMeter calculates the
throughput of each type of HTTP Request.
My jmeter.properties setting has the default
sampleresult.timestamp.start=true
which is suppose to log the timestamp of when a HTTP
Request starts in the .JTL file.
So for example, I have the following results in csv
format
TIMESTAMP|TIME|LABEL|RESPONSE CODE|RESPONSE MSG|THREAD
NAME|DATATYPE|SUCCESS
1086285141198|10|Request 1|200|OK|Thread
Group1-2|text|true
1086285141248|40|Request 2|200|OK|Thread
Group1-2|text|true
1086285141258|20|Request 1|200|OK|Thread
Group1-1|text|true
1086285141309|51|Request 2|200|OK|Thread
Group1-1|text|true
JMeter calculates the throughput per second as
(count/howLongRunning) * 1000.0
The part where I'm confused about is the
howLongRunning time. The source code says that the
total time passed is taken to be the timestamps of the
first and last samples. The timestamps are suppose to
be the start time of each request, according to the
jmeter properties configuration.
So for Request 2, the last sample timestamp is 41309
while the timestamp for the first sample is 41248.
JMeter calculates by
(2 / (41309 - (41248 - 40))) * 1000.0
Why does it take the first sample and subtracts the
response time that it took to execute the first
Request 2?
I would think that instead, it should add the response
time of the last Request 2 to the Request 2 timestamp
(41309 + 51). That would actually be the time passed
from the first Request 2 to start and really end with
the last Request 2.
Is the timestamp really the start time of the request?

I think the problem is with reading the file; I have a test.csv file in

RE: Embedded JavaScript files are being parsed as HTML
I tried with the nightly jakarta-jmeter-20 build and this problem is not there

If there are other examples of HTML that are not being parsed correctly, it

The current test files are in bin/testfiles.
A new parser can be added, but you will need to write a JMeter wrapper to
call the relevant parser code using its particular API.
This should be fairly easy - have a look at one of the existing wrappers.

Subject: Embedded JavaScript files are being parsed as HTML
Hello,
I am running an HTTP test script, where I have the HTTP Samplers loading
embedded resources. On some pages, one of the linked JavaScript files has a
function to output an HTML page. It appears that JMeter is parsing this code
as if it is HTML and following the embedded links. The offending
JavaScript looks like this:
function writePleaseWaitMessage(doc, nextUrl)
{
doc.open();
doc.writeln();
doc.writeln();
doc.writeln();
doc.writeln(
href=\/styles/RedFlagStyles.css\);
doc.writeln(
href=\/styles/tenetstyles.css\);
doc.writeln();
doc.writeln(onLoad=\javascript:window.location=', nextUrl, '\);
// ... and so on
}
The rather strange result in JMeter (Results Tree) is:
+- Root
|- /jsp/logon.jsp
|- (other links from /jsp/logon.jsp)
+- http://localhost/javascript/redflag.js
(200)
| |- http://localhost/javascript/redflag.js
(200)
| +- http://localhost/javascript/\-http://localhost/javascript/\/
(404)
| |- http://localhost/javascript/\
(302)
| |- http://localhost/javascript/\/
(404)
|- (more links from /jsp/logon.jsp)
When I remove the lines in the JS function that output
tags,
everything works as expected. Apparently the HTML parsing code sees href=\
and tries to follow it. The correct behavior, though, would be for the
parser to ignore it, since the resource has a MIME type of
application/x-javascript. Is this a known issue, or should I create a
Bugzilla report? Also, if someone can point me to a likely place in the
code, I'll investigate it and try to fix it.
Thanks,
Eric

Re: While loop functionality
I tried with the June 3rd nightly build and this workaround for a while
loop isn't quite working.
There are two problems:
1. Using the Test Action sampler doesn't execute the IF condition at
all--only when I put a real sampler like an HTTP Request sampler.
2. The IF condition only evaluates once. When the loop executes a
second time, the IF condition doesn't seem to evaluate at all and
therefore, the loop ends. I made sure the IF condition should evaluate
by setting the condition to 1 == 1. I read in previous messages that
other users have seen similiar behavior but no resolution was given. I
tried searching through bugzilla for such a bug but didn't see one.
Has anyone tried this while loop workaround?
For the User Parameters, should the Update Once Per Iteration be
unchecked?
thanks,
mabel

Subject: Re: While loop functionality
Date: Thu, 29 Apr 2004 12:23:30 -0700
Actually there is a way to do this.
I've made some modifications to the ForLoop controller
to allow it to use a JMeter variable as a loop
counter. What you do is initialize a JMeter variable
to 1...and use that JMeter variable as the loop
counter. If you want to loop again then increment the
counter variable and you'll loop again.
Your test tree would look something like:
Test Plan
|
Thread Group
|
MatchTest
|
User Parameters
i=1
/pages/login.jsp
/pages/j_security_check
/pages/main.do
/pages/top.jsp
/pages/test.tst
LoopController
Loop Count: ${i}
|
/pages/taskList.do
|
Regular Expression Extractor
Reference Name: done
Regular Expression: Done
Template: true
Match No: 1
Default Value: false
If Controller
Condition: !${done}
|
User Parameters
i=${__javaScript(${i}+1,)}
Test Action
Target: Current Thread
Action: Pause
Duration: 0
/pages/logout.do
Basically, what's happening here is that you are going
to execute the /pages/taskList.do http request at
least once. If the text Done is found than the JMeter
varible ${done} is set to true, else false. The If
Controller is a child of the Loop Controller and
increments the value of ${i} if !${done} is true (the
text Done wasn't found). You have to stick the Test
Action in the if controller because the controller
won't execute at all if it doesn't have a sampler to
sample.
Test Action is a new Sampler that I added a few weeks
ago that will either pause or stop the current thread
or the entire test based on how you set it up. It's a
sampler because that was the only way to introduce
this functionality without completely rewriting
JMeter. Plus, I think it's pretty convenient for use
in the above scenario...It basically pauses the test
for 0 milliseconds. The Test Action sampler doesn't
actually return a sample. You can use any other
sampler in its place for that matter.
Note: The above scenario only works with the current
code in the nightly build.
Regards,
Thad Smith
P.S. There has been talk of creating some eclipse
plugins that allows you to run JMeter inside of a Java
program in eclipse, but nothing has been done yet.

RE: how to run a logout transaction once
You're right, I don't need a Once Only Controller if the ThreadGroup is set to loop once. Thanks for implementing the Run Controller. I look forward to testing and using that feature in a few days.

However, I just don't know where to start with implementing a finally controller, sorry. == It seems to me that the Once Only controllers are not needed if the threadgroup only loops once.

embedded resources. On some pages, one of the linked JavaScript files has a
function to output an HTML page. It appears that JMeter is parsing this code
as if it is HTML and following the embedded links. The offending
JavaScript looks like this:
function writePleaseWaitMessage(doc, nextUrl)
{
doc.open();
doc.writeln();
doc.writeln();
doc.writeln();
doc.writeln(
href=\/styles/RedFlagStyles.css\);
doc.writeln(
href=\/styles/tenetstyles.css\);
doc.writeln();
doc.writeln(onLoad=\javascript:window.location=', nextUrl, '\);
// ... and so on
}
The rather strange result in JMeter (Results Tree) is:
+- Root
|- /jsp/logon.jsp
|- (other links from /jsp/logon.jsp)
+- http://localhost/javascript/redflag.js
(200)
| |- http://localhost/javascript/redflag.js
(200)
| +- http://localhost/javascript/\-http://localhost/javascript/\/
(404)
| |- http://localhost/javascript/\
(302)
| |- http://localhost/javascript/\/
(404)
|- (more links from /jsp/logon.jsp)
When I remove the lines in the JS function that output
tags,
everything works as expected. Apparently the HTML parsing code sees href=\
and tries to follow it. The correct behavior, though, would be for the
parser to ignore it, since the resource has a MIME type of
application/x-javascript. Is this a known issue, or should I create a
Bugzilla report? Also, if someone can point me to a likely place in the
code, I'll investigate it and try to fix it.
Thanks,
Eric

RE: how to run a logout transaction once
I'm sure that two thread groups can't access the same cookie and it would be considered two different sessions, which would not work for me. But thanks for the suggestions. What I need is a finally controller as Joe Casadonte mentioned, which hasn't been implemented. BAZLEY, Sebastian [EMAIL PROTECTED] wrote: In that case, you *might* be able to use two thread groups and run them consecutively. However, I don't think thread groups can access each others cookies or variables. This might cause you problems - cannot be sure from the information you have provided.

Re: Jmeter accuracy (applets, load, response)
I have a few more questions/comments about how JMeter measures response times. Suppose I have the following Test Plan structure that is set to run twice by one user: Test Plan Thread Group HTTP Cookie Manager Simple Controller 1 HTTP Request A (Retrieve all embedded resources) HTTP Request B (Retrieve all embedded resources) Timer - 5 seconds Aggregate Report 1 Simple Controller 2 HTTP Request C (Retrieve all embedded resources) HTTP Request D (Retrieve all embedded resources) HTTP Request B (Retrieve all embedded resources) Aggregate Report 2 1. There doesn't seem to be an option for JMeter to not retrieve embedded resources once it has been retrieved the first time. In other words for JMeter to simulate a browser cache. In my example, the first loop will retrieve all embedded resources for all the requests. The second loop through would do the same for the same user. Furthermore, it would be nice during the first loop, when encountering Request B again in Simple Controller 2, that it would not retrieve embedded resources for Request B. So it would seem that the response time for the requests will always be measuring first cache hit scenario. 2. Peter, you said that JMeter measures the total elapsed time. Just to clarifyFor example, on a HTTP Request A that is run only once, does the measurement time start when the first byte request is sent and the measurement time stops when the very last byte response is returned which could well be the byte from an embedded file? Or is it the measurement starts after a virtual user has sent the last byte of the request and ends when the user retrieves the first byte of the response. 3. The Timer under the first HTTP Request B does not get calculated to the response time for Aggregate Report 1, which is what I want. However, if using the Transaction Controller, it does. Transaction Controller should have an option to measure with Timers or not. 4. I suppose JMeter currently does not measure the number of KB a page request/response takes? Is this planned to be implemented? Thanks, Mabel Re: Jmeter accuracy (applets, load, response) From: peter lin Subject: Re: Jmeter accuracy (applets, load, response) Date: Wed, 12 May 2004 10:58:11 -0700 most of this is in the component documentation. http://jakarta.apache.org/jmeter/usermanual/index.html the response time you see in JMeter is the total elapsed time. If you do not check retrieve all embedded resources from HTML files, it is just the html. If you check it, it is the total time to get all the resources including html. Remember the response times are always estimates and never use the average as actual response time from a user's perspective. Since JMeter does not render the pages, the response time is faster than the total time to transfer the data + browser rendering time. Depending on how deeply nested the html tables are, it could take the browser and additional 2-5 seconds to draw the page. keep in mind network latency can greatly affect the user's perception of response time. If someone is using a bad modem, the page will load considerly slower. I tend to error on the side of safety and state the results are only indicators of likely performance :) you'd be amazed at how people will interpret the results. peter Steve Luong [EMAIL PROTECTED] wrote: Hey guys, I was wondering how accurate is Jmeter in measuring load time. I'm working on a report for a client and I need to know are these numbers reliable. I've only been working on Jmeter for a few days and everything looks promising. A few questions I would like to know is are there any hints anyone can provide to give me the most accurate information on the load times. Also when Jmeter is set to follow all elements in the html page like images does it do applets too? Does it measure the complete time it takes to download the applet or just the time it takes to send the applet? Having this knowledge would greatly help in my efforts. Thanks for all the help!
