Re: Jmeter - MySQL Cluster

[glin...@live.com]

Just the same way you do this for a single instance.

The main rule you should remember: well-behaved load test must represent
real-life application usage as close as possible. So if the MySQL cluster is
used by some external system and you want to conduct some performance
testing - you need to use the same configuration as that external system in
terms of  URL
  , 
connection pool   , etc. 

With regards to the URL itself you can specify the protocol like
*loadbalance* and include all your hosts there:


> jdbc:mysql:loadbalance://[host1][:port],[host2][:port][,[host3][:port]]...[/[database]][?propertyName1=propertyValue1[=propertyValue2]...]

I don't think this statement is correct, JMeter Assertions obey  JMeter
Scoping Rules
   so if
you put  JSON Assertion
  
(or even better  JSON JMESPath Assertion

 
) at the Thread Group level - it will be applied to *all samplers* in all
Thread Groups. 

Hopefully this is something you're looking for

Re: Problem: getting Not a valid web socket request.

[glin...@live.com]

As per latest stable JMeter version  5.4.1

  
JMeter's  HTTP(S) Test Script Recorder

  
is only capable of recording HTTP or HTTPS traffic (as it evidenced by its
name) 

WebSockets   is
a different beast which cannot be either recorder by JMeter or replayer
using any of Samplers so if you need to mimic websocket traffic you will
need to use a plugin like WebSocket Samplers
   

The request payload can be captured using your  browser developer tools

  
or external 3rd party sniffer tool like  Fiddler
  or  Wireshark
  .

Re: Jmeter not substituting variable in CSV Data Set Config

[glin...@live.com]

Of course it doesn't. Could you please bookmark the  Execution Order
   
chapter and re-read it prior to asking the next question. 


CSV Data Set Config is a *Configuration Element* so it's being executed
before the JSR223 Sampler and in fact before everything else. 

The only configuration element which takes precedence is  User Defined
Variables

  
so you can define your *testdata* variable there and if you want to make it
dynamic - use __groovy() function
   to
calculate/assign the value.

So I would recommend checking which ports are being used by JMeter using

You will also need to configure the  port forwarding
   on NAT level otherwise the
master won't be able to "see" the slave.

Re: SV: Response assertion seems to not always set JMeterThread.last_sample_ok correctly

[glin...@live.com]

I might be suffering from a form of a mental fatigue but I pretty much sure I
posted the link to the JMeter test elements  execution order
  

Response assertion is executed *AFTER* the JSR223 PostProcessor so if the
assertion fails the request - you will get false positive result. 

You need to change it to the  JSR223 Assertion

  
(but make sure to place it *below* the Response Assertion as they're
executed upside down) or switch to the  JSR223 Listener
 
.

The questions is: how exactly you're "logging that the variable
JMeterThread.last_sample_ok"? 

Be aware of JMeter test elements  execution order
  ,
after Assertions only Listeners are executed so it makes sense to "log" the
value for example using  JSR223 Listener
   and the following code:


> log.info('Previous sampler successful: ' +
> vars.get('JMeterThread.last_sample_ok'))

Also you can log the value using  __log()
  or  logn()
   functions
which are evaluated immediately where they found

In general  according to JMeter Best Practices you should always use the

Re: Hits/min JMeter understanding

[glin...@live.com]

It mostly depends on the protocol, in case of  HTTP
   single "transaction"
may produce more than one hit due to  redirects
   or
downloading  embedded resources

  
(images, scripts, styles, fonts, sounds, etc.)

In case of missing redirects/embedded resources (i.e if you're testing an
API) one sampler generates only one hit and it could be the explanation of
your metrics. 

You cannot calculate/estimate/predict how many hits will a single sampler
generates as it mainly depends on your system under test, however you can
measure it using i.e.  Server Hits per Second
   listener

Re: Bug? JMeter is not using the default groovy

[glin...@live.com]

For sure it's not a JMeter bug, it's an example of  Jar Hell
   where you have multiple
versions of the same library in the  CLASSPATH
  


There are groovy-*.jar libraries in JMeter Classpath
   (lib
folder of your JMeter installation) and JMeter automatically loads them on
start and if you're adding more Groovy libraries to the classpath by any
means it results in 2 same libraries of different versions with undefined
order when it comes to classloading. 

If you want to use your own Groovy - remove JMeter's version and vice versa. 

Just in case if you cannot remove JMeter's libraries, the latest version of
JMeter which was shipped with Groovy 2.4.12 was  JMeter 3.3
  

Also  according to JMeter Best Practices you should always be using the
latest version of JMeter
   which is 
JMeter 5.4.1

  
as of now and it comes with Groovy 3.0.7 so switching to JMeter's groovy or
upgrading your installed SDK might be a viable solution.

Re: Can't override Connection header

I don't think you can do this using HTTP Header Manager, the header is
controllable via "Use KeepAlive" box in HTTP Request sampler 

If you need to parameterize the Connection header I can think of adding
JSR223 PreProcessor

  
and using the following code:


> sampler.setUseKeepAlive(false) // for Connection: close

or


> sampler.setUseKeepAlive(true) // for Connection: keep-alive


Alternative option would be switching to  HTTP Raw Request sampler

  
which gives you full flexibility in building request headers and body

Re: Performance Testing Load Balanced Application

[glin...@live.com]

1. JMeter doesn't know anything about your application infrastructure, when
it comes to load testing load balanced applications it's a good idea to add 
DNS Cache Manager

  
to your Test Plan so each thread (virtual user) would resolve the IP address
of load balancer on its own. Also if there is some form of  session
stickiness

  
you can trace down the relevant HTTP Header or part of the URL. If you need
insights what happens under the hood of your application infrastructure
during the load test you should go for an  APM tool

  

2. JMeter automatically aggregates all the results no matter of the origin
(thread group), if you need to have ability to distinguish results coming
from different thread groups you can use  __threadGroupName()
  
function for this

Re: Problem with client certificates - No certificate found for alias:'john_doe'

[glin...@live.com]

It's hard to say what's wrong without seeing your jmeter.log file
  , CSV Data
Set Config and Keystore Config setup so I can only give a generic piece of
advice: what you put into "Variable Names" in the CSV Data Set Config must
match what your put into "Variable name holding certificate alias" in the
Keystore Config, also ensure that "Alias start index" is 0 and "Alias end
index" is -1 so Keystore Config would load all the certificates in the
keystore. 

See  How to Use Multiple Certificates When Load Testing Secure Websites

  
article for more details. 

If you need only one certificate from the keystore you can  extract it into
a separate keystore
   like 


> keytool -importkeystore -srckeystore c:\temp\keystore.p12 -destkeystore
> c:\temp\onecert.p12 -srcstorepass secret --deststorepass secret -srcalias
> intuser_cindy

This way you will have *onecertp.12* keystore with only one certificate
which can be used directly without having to add CSV Data Set Config or
KeyStore Config

Re: Error message help

By default JMeter 5.3

  
has 1GB of JVM Heap space allocated, it should be sufficient for tests
development and/or debugging but might not be enough for the full load test. 

The ways to increase the heap are:

Set *HEAP* environment variable and provide more maximum JVM heap size,
default settings are:


> -Xms1g -Xmx1g -XX:MaxMetaspaceSize=256m

you can try increasing it twice and see how it goes. 

Another option is to find the above line in jmeter startup script
(jmeter.bat on Windows or jmeter on other operating systems) and ramp-up the
heap size, start with something like 80% of your total available physical
RAM and adjust up or down as needed

If you have a Thread Group with 10k virtual users, no ramp-up, no timers so
JMeter is running at full speed and you have 10k requests executed in 30
seconds I can think of 2 reasons for this:

 1. Your application cannot respond fast enough which means you found the 
bottleneck  
, there is no sense to continue until the bottleneck is identified and fixed
 2. JMeter cannot send requests fast enough. Make sure to follow  JMeter

You cannot "pause" JMeter, the only way to stop it sending the requests is

Check out  How to Change JMeter´s Load During Runtime

Alternative option is using  Filter Results Tool

Re: sampleEnd called twice

[glin...@live.com]

The correct solution would be storing your *dt* into a JMeter Variable like:


> vars.put('dt', dt as String)

then you can declate this *dt* as a  Sample Variable
   and 
generate a custom graph over
 
time out of it

If it's too complex you can update your JSR223 Sampler execution time from
the JSR223 PostProcessor like:


> prev.elapsedTime = vars.getObject('dt') as long

See  Top 8 JMeter Java Classes You Should Be Using with Groovy

  
article for more information regarding what these *vars* and *prev* stand
for and remember each time you bypass JMeter limitation using reflection
somewhere somehow a kitten dies.

Re: Please help with MIME Type for .CSAR file

[glin...@live.com]

Looking into  CSAR file extension
   page:

So try using *application/octet-stream* and presumably it should resolve
your issue. 

Going forward if you will face difficulties with manually configuring the 
HTTP Request
 
sampler for file uploads be aware that you can always just record the file
upload request using JMeter's  HTTP(S) Test Script Recorder

 
, just make sure to  copy the file(s) you will be uploading to the "bin"
folder of your JMeter installation
   prior to
executing the request in browser, JMeter should be smart enough to detect
the media type of the file.

Re: Error loading result file with ~/ prefix in Windows 10

[glin...@live.com]

*~* symbol is a normal file or folder name in Windows 10, you're getting this
error because *~\resultstree.xml* file does not exist. 

If you create the *~* folder in the "bin" folder of your JMeter installation
and change the file path to *~\resulttree.xml* the issue will go away and
JMeter starts writing the results to the
*c:/path/to/your/jmeter/bin/~/resulttree.xml*


Going forward consider  enabling JMeter debug logging

You can go for the  If Controller
  
and use the following  __jexl3() function

This way If Controller's children will be executed only at the slave machine

If your test assumes multiple threads (virtual users) and iterations on

Re: Problem with Jmeter and client certificate authentication - unknown_certificate

[glin...@live.com]

Most probably there is a problem with the test data, i.e. alias is missing in
the keystore or wrong certificate lives under the correct alias. 

First of all I would recommend cross-checking your aliases in the keystore
and in the CSV file, you can get the list of aliases from the keystore using 
keytool
 
command like:


>  a
> keytool -list -v -keystore /path/to/your/keystore | find "Alias"

For example when I use JMeter's "proxyserver.jks" as the keystore I'm
getting the next 2 aliases:

 


> :root_ca:
> :intermediate_ca:

it means that I need exactly these 2 entries in the CSV file holding the
certificate aliases.

So my expectation is that you see "future" information in the listeners

Re: Java request in distributed testing

[glin...@live.com]

If you're talking about *Java* implementation of the  HTTP Request
  
sampler, according to the documentation:


The Java HTTP implementation has some limitations:

There is no control over how connections are re-used. When a connection is
released by JMeter, it may or may not be re-used by the same thread.



So if you're suffering from the above issue you should consider switching to
the  HttpClient4   implementation 

If you're seeing Connection header with the value of *keep-alive* - just
untick "Use KeepAlive" box in the HTTP Request Sampler (or even better  HTTP
Request Defaults

  
so the changes would be propagated to all HTTP Request samplers)

If you're talking about  Java Request
  
sampler - unfortunately no one will be able to help unless you share your
code, I can only recommend using a profiler tool like  YourKit
  , it should be able to detect
obvious memory leaks like not closed connection.

In the absolute majority of cases you cannot replay the recorded script "as

You need to identify all these dynamic parameters, extract them from the

Re: Problems Execute Linux Commands using JSR223 PrePrcessor with Groovy Engine and pipe-symbol

As you correctly mentioned, "it's working perfect on bash". 

Groovy knows nothing about the pipe symbol so you need to execute  bash -c

Groovy neither knows your *$path* environment variable, if the environment
variable exists and is available to JVM you can read its value using 
System.getEnv()
  
function

It might be easier to go for  OS Process Sampler

 
, check out  How to Run External Commands and Programs Locally and Remotely

 2.  create file `network_security_config.xml` under  res folder
  
of your application and put the following code inside it: 3.
Re-compile your application in  debug flavour
  
> gradlew assembleDebug

4. Replace the application on the device with the newly build debug version
- this one you can record with JMeter. If you don't have access to your

Re: Jmeter System Preferences Lock Error

[glin...@live.com]

Looking into  JMeter Bug 61279
   it isn't something
connected with JMeter, I can think of the following reasons for the
behaviour:1. You have more than 1  JVM
  running on the EC2
machine and these JVMs are suffering from a form of a  race condition
   when trying to obtain the
lock on the same file to store the preferences2. There is a problem with
Linux file permissions and JVM, i.e. you're running out of  free handles
  The
solution for point 1 would be explicitly specifying the store for 
systemRoot

 
and  userRoot

 
for the JVM which hosts JMeter so it would use the separate preferences
storage not shared with other JVMs. The properties can be defined either via 
-D command-line argument
   like:
> ./jmeter -Djava.util.prefs.systemRoot=/some/folder/.jmeter
> -Djava.util.prefs.userRoot=/some/folder/.jmeter/.userPrefs

In order to make the changes persistent you can add the same lines to
/system.properties/ file (lives in "bin" folder of your JMeter installation)
> java.util.prefs.systemRoot=/some/folder/.jmeterjava.util.prefs.userRoot=/some/folder/.jmeter/.userPrefs

More information:  Apache JMeter Properties Customization Guide
 
In case of point 2 I would recommend checking / raising  Linux process

It is impossible to come up with the comprehensive response without seeing

the file2. Tick "Use multipart/form-data" box in the  HTTP Request
  
sampler 3. Make sure to use correct "Parameter Name" under the "Files

input   In general
given you can successfully execute the request using Postman you could
record the request using JMeter, just  configure Postman to use JMeter as
the proxy

 
, start JMeter's HTTP(S) Test Script Recorder,  copy the file you will be
uploading to JMeter's "bin" folder
   and
execute the request in Postman. JMeter will capture the request and store it
under the  Recording Controller

Re: Reducing Timer with While Loop

You need to obtain the current timestamp prior to entering the loop and save
it into a  JMeter Variable
  .  It can be done
using the following  __groovy() function
  
> ${__groovy(vars.putObject('start'\, System.currentTimeMillis()),)}

Now you have loop start time hence you can introduce 2  clauses for the
while loop, it can be done using the aforementioned __groovy() function
which needs to be put into the  While Controller's

  
"Condition" input field:
> ${__groovy((vars.get('callAPIVariable').equals('true') &&
> (System.currentTimeMillis() - (vars.getObject('start') as long) <
> 3)),)}

Assuming the above setup the While Controller will loop over until
*callAPIVariable* value is *true* or 30 seconds pass, whatever happens the
first. See  The Groovy Templates Cheat Sheet for JMeter
  
article to learn what else can be done using Groovy scripting in JMeter

Re: Script error

[glin...@live.com]

In the majority of cases it is not possible to successfully replay recorded

My expectation is that the request which adds the item to the card relies on
a some dynamic value which is not valid anymore and either needs to be
extracted from the previous request using a suitable  JMeter PostProcessor
  
or it's something specific to the application you're testing, for example if
you have already added an item to the cart it cannot be added one more time
as it's there already. 

So add  View Results Tree listener

  
to your Test Plan and run your test in GUI mode inspecting request and
response details, it might be the case that you're not getting logged in
hence all requests which require authentication are failing. 

If you're a BlazeMeter customer the easiest option is  raising a support

Re: Login issue when executing test on server side

[glin...@live.com]

If the issue cannot be reproduced for lesser number of virtual users (i.e. 1,

(can be checked using i.e.  JMeter PerfMon Plugin

 
), has wrong configuration of application server / database / load balancer
or the application itself is not optimized for high loads (can be checked
using  profiler tools
  )

Another possible reason is that JMeter is not capable of sending requests
properly due to lack of resources or improper configuration. Theoretically
you should be able to easily simulate 200 users even using default JMeter
setup and single node assuming you  run your test in non-GUI mode
  , however
it's better to make sure that you're following  JMeter Best Practices
   and that JMeter
has enough headroom to properly operate.

Re: reading part of request body from a file

[glin...@live.com]

It is, take a look at  __FileToString() function
   which
you can use directly in the HTTP Request sampler "Body Data" tab where it is
required to add this header. 

Given you have nested functions inside the payload you will also need to
wrap it into  __eval() function
   so they would
be evaluated in the runtime


> ${__eval(${__FileToString(/path/to/your/file,,)})}

Re: unable to create new native thread error

[glin...@live.com]

The error looks like an  OS level limitation
  
of the number of processes so you need to amend underlying operating system
configuration in order to allow at least that many processes as virtual
users. 

See  Maximum number of processes in linux

  
for more details. 

Given the number of virtual users you're trying to simulate it makes more
sense to go for  distributed testing
  
as my expectation is that investing into a couple of AWS machine would be
much cheaper than the time and effort you will spend by trying to conduct
this load using a single host.

Re: Jmeter & application logging concern

[glin...@live.com]

I don't fully understand why you're asking questions not related to JMeter in
JMeter mailing list, however just in case other person will make the same
mistake:

1. You're going into wrong direction, instead of redirecting STDOUT to
jmeter.log file you should be doing the opposite thing: copying messages
which should be going to the jmeter.log file to STDOUT. Given the nature of
your query I strongly doubt you will be capable of do this yourself so here
you go:


> 
> 
> 
> 
>  append="false">
> 
> 
> 
> 
> %d %p %c{1.}: %m%n
>

> 
> 
> 
> 
>

>

> 

2. The above step will give you the output in "Jenkins console". If you
additionally want to have it in the file - you can use the underlying OS
shell  redirection operator
   to
save the STDOUT / STDERR outputs into the file. Again looking into your
question I expect you will post the next one right here so kindly find an
example (this is for  Bash   
shell):


> jmeter -n -t test.jmx -l result.jtl > jmeter.out >file.txt 2>&1

Double check that:

latest version available at  JMeter Downloads
   page)
2. Your Java application has  ApacheJMeter_functions.jar

Re: Regular Expression Help

[glin...@live.com]

Add  JSON Extractor
  
as a child of the request which returns the above JSON and use the following
expression:

Explanation:

1.  .. - is a deep scan operator
   so the expression
searches for all the *productID* attribute values

 2.  == is a filter operator
   so the expression
will return productID only when isComplete equals to 0

I doubt that you find this useful for storing "the input of your choice",

With regards to your question itself, *Filename* column holds the value of

Re: send email with results in View Results Tree as attachment

[glin...@live.com]

As per current JMeter version ( JMeter 5.0
  ) it is hardly
achievable (unless you want to come up with a  custom plugin
  )

I would recommend the following alternative approaches:

 1. Configure JMeter to save all the request and response data, for example
you can add the next lines to /user.properties/ file:


>  jmeter.save.saveservice.output_format=xml
>  jmeter.save.saveservice.response_data=true
>  jmeter.save.saveservice.samplerData=true
>  jmeter.save.saveservice.requestHeaders=true
>  jmeter.save.saveservice.url=true
>  jmeter.save.saveservice.responseHeaders=true

and then send the XML results file - the recipients will be able to open it
using View Results Tree listener

 2. Provide high-level summary instead of details per request. You can
generate a CSV form of the  Aggregate Report
 
 
listener using  JMeterPluginsCMD Command Line Tool
   and  Synthesis Report
   plugins, the relevant
command to generate the textual form of the Aggregate Report would be
something like:


> JMeterPluginsCMD.sh --generate-csv file-to-send.csv --input-jtl
> JMeter-test-result.jtl --plugin-type AggregateReport

Your test relies on  Parameterized Controller

The easiest way of installing plugins and keep them up-to-date is using 
JMeter Plugins Manager

Re: What is the relationship between JVM XMX and XMS in jmeter and the number of concurrent users

[glin...@live.com]

JMeter is a normal Java application hence you should treat it as any other
Java application in terms of  performance tuning
  

There is no "silver bullet" instruction. Neither anyone can tell how many
users you will be able to simulate for this or that test as "it depends".
Mainly it depends on:

1. Nature of your test (what the test is doing, request and response size,
number of  Preprocessors
 
,  Postprocessors
 
,  Assertions
  , etc).
Remember that any test element has its cost and try to limit their usage to
absolute viable minimum. 

2. It is not possible to provide "recommended" minimum and maximum heap
values as it also depends on how JMeter copes with the load. You can see
what's going on using  JVisualVM
  
tool. First of all, maximum heap should be big enough in order to fit in
JMeter, all thread variables, requests and responses data for all the
threads, if the data will not fit into heap - you will get 
java.lang.OutOfMemoryError: Java heap space

 
. Going forward if JVisualVM shows that Java spends too much time doing GC -
you might want to increase heap size and vice versa, you might want to
decrease heap usage to give resources to other processes. 

3. Remember that any heap manipulation should be followed by the amendment
of other parameters like  MaxMetaSpaceSize
  

So start with default settings and ensure that:

1. Java uses machine resources efficiently, i.e. you don't have too many
spare RAM and CPU
2. System isn't overloaded,  i.e. there is no lack of CPU or RAM
3. JVM doesn't spend too much time doing GC

If you performed all the optimisations and still unable to conduct the
required load - you will have to go for  Distributed Testing

Re: jmeter - replay

[glin...@live.com]

1. JMeter automatically treats responses with  HTTP Status Codes
   below 400 as
successful. It doesn't do any extra checks so you might want to introduce 
Assertions
  
in order to verify that your test is doing what it is supposed to be doing. 

2. Make sure to add  HTTP Cookie Manager

  
to your Test Plan

3. Record the same scenario one more time and compare the recorded scripts.
If you see the differences - these values need to be *correlated* - to wit
extracted from the previous response using suitable JMeter  Post-Processor
  
and stored into  JMeter Variables
  . Once done you will
need to replace hard-coded values which need to be dynamic with the
aforementioned variables.

Re: HTTP Request's Content Encoding field

[glin...@live.com]

It is being used at least:

 1. For  setting request header

  
 2. For  encoding POST request data

  
 3. For  encoding query string

  

The easiest way of testing this is setting Content Encoding to something,
which cannot be resolved to a  Java Charset

 
, in this case you will immediately get an  UnsupportedCharsetException

  

Another option of testing this is using  View Results Tree
  
listener, if you leave the Content Encoding input blank - JMeter will send
default charset (UTF-8). If you set the encoding of your choice - JMeter
will add this as the  Content-Type header
  
*charset* parameter

Re: Sent request with no User-Agent header

[glin...@live.com]

As per  HttpClient JavaDoc

  


> This class sets up the following parameters 
*
> if not explicitly set
*
> :
> 
> Version: HttpVersion.HTTP_1_1
> ContentCharset: HTTP.DEFAULT_CONTENT_CHARSET
> NoTcpDelay: true
> SocketBufferSize: 8192
*
> UserAgent: Apache-HttpClient/release (java 1.5)
*

I don't think there is an easy way of disabling this (unless you would like
to go for  Reflection
 
)

If you don't want the User-Agent header you can switch to "Java"
implementation, the setting lives under "Advanced" tab of the HTTP Request
sampler (or even better  HTTP Request Defaults

 
, this way the setting will be applied to all the HTTP Request samplers in
its scope and you will not have to revisit each one individually)  

Also be aware that according to JMeter Best Practices  you should always be
using the latest version of JMeter
  
so consider upgrading to JMeter 5.0 (or whatever is available at  JMeter
Downloads    page) on next
available opportunity

Re: JMeter 4 with Java 1.7

[glin...@live.com]

According to  JMeter changelog
   the latest JMeter version
which is compatible with Java 7 is  JMeter 3.1
  

I don't think you will be able to use  JMeter 4 with Java 7 as it simply
will not compile. 

With regards to "organization" if you really need JMeter 4 you can point the
responsible persons to  JMeter Best Practices you should always be using the
latest version of JMeter
  , moreover the
end of public updates for Java 7 was in April 2015 (>3 years ago)

Be aware that you can always download Java 8 (or higher) from OpenJDK
archives    or use  Java 8 Docker containers

Re: Print thread groups including comments fields of underlying controllers

[glin...@live.com]

You can use  SearchByClass

  
functions in order to fetch information on Include Controllers from the Test
Plan. 

Here is an example with regards to how this can be done from JMeter test
itself using  JSR223 Sampler
  
and  Groovy   language :

 1. Add  tearDown Thread Group

  
to your Test plan
 2. Add JSR223 Sampler to the tearDown Thread Group
 3. Put the following code into "Script" area:



> import org.apache.jmeter.engine.StandardJMeterEngine
> import  org.apache.jmeter.control.IncludeController
> import org.apache.jorphan.collections.HashTree
> import org.apache.jorphan.collections.SearchByClass
> import java.lang.reflect.Field
> 
> StandardJMeterEngine engine = ctx.getEngine()
> Field test = engine.getClass().getDeclaredField("test")
> test.setAccessible(true)
> HashTree testPlanTree = (HashTree) test.get(engine)
> 
> SearchByClass
> 
>  includeControllerSearch = new SearchByClass<>(IncludeController.class)
> testPlanTree.traverse(includeControllerSearch)
> Collection
> 
>  includeControllers = includeControllerSearch.getSearchResults()
> log.info('**')
> includeControllers.each {
> log.info('Module: ' + it.getName() + ' Comments: ' + it.getComment())
> }
> log.info('**')



This way you will get the information on Include Controllers printed to
/jmeter.log/ file 


 

So you can either find the information in the jmeter.log file by searching
for the above asterisks or amend the code to be a standalone application and
create PDF using i.e.  Apache PDFBox   , anyway
further steps are out of scope for this mailing list.

there will be a line break - it will run your regex).

If your application talks to the database directly you can use JMeter's  JDBC

queries to the backend.

 1. Download  Microsoft JDBC Driver for SQL Server

  
and drop the .jar (and .dlls if you are going to use native authentication)
to  JMeter Classpath
   and 
java.library.path

 2. Restart JMeter to pick up the libraries
 3. Add  JDBC Connection Configuration

  
and define database URL, credentials and other settings there
 4. Add a JDBC Request sampler per simulated query and put your query there

if your application uses different protocol(s) you will not be able to
record its network activity with JMeter. 

Be aware that:

 1. You might need to amend your *operating system* proxy settings if your
application doesn't have separate proxy configuration
 2. You might need to install  JMeter's self-signed certificate

  
into your operating system certificate storage

 1. Prepare JMeter for recording. The fastest and the easiest way is using 
JMeter Templates Feature

 
. From JMeter's main menu choose *File -> Templates -> Recording* and click
*Create*
 2. Prepare Postman for recording. All you need to do is to configure it to

 3. Run your test

Re: jmeter command stuck - FTP testing

[glin...@live.com]

As of JMeter 4.0 underlying  FTPClient

  
doesn't have any timeouts so if your server will never respond - your JMeter

You can work it around by placing your FTP requests under the  Runtime
Controller

  
- this way you will get confidence that your test will be terminated by the
Runtime Controller. 

Another option is switching from JMeter's FTP Request sampler to  JSR223
Sampler

  
where you will have full control over FTPClient instance and will be able to
define all the timeouts you can think of


> FTPClient ftpClient = new FTPClient(x);

Re: Parallel Logic Controller

[glin...@live.com]

It depends on the nature of the requests. If you need to mimic a "spike",
i.e. need to simulate 50 users concurrently doing the same action, i.e.
checking out an item, logging in, voting, etc. - you don't need any plugins,
JMeter's Synchronizing Timer

  
will be sufficient.  

Parallel Controller comes into play where you need to implement some "egde"
conditions, for example if after login your application dashboard is being
loaded in several parallel threads originating i.e. via  AJAX
   requests.  In this case you
won't be able to easily simulate this type of load using JMeter built-in
test elements, however with the Parallel Controller it is a matter of
seconds. Check out  How to Use the Parallel Controller in JMeter

   into Groovy code. 

As per  JSR223 Sampler documentation
  


> When using this feature, ensure your script code does not use JMeter
> variables directly in script code as caching would only cache first
> replacement. Instead use script parameters

 

If you're looking for a "pure"  Groovy
   equivalent of your code
it would be something like:


> vars.put('MESSAGE', new File('C:\\Users\\xyz\\Desktop\\Test.txt').text)

Re: Avg field not visible in .jtl file < Urgent pls >

[glin...@live.com]

You will not find average value as it is being *calculated*, it is basically
an  arithmetic mean    of the
response times (sum of all responses times divided by their count)

You can get it from the .jtl results file either by applying above formula
or using  JMeterPluginsCMD Command Line Tool
   which is capable of
generating CSV version of the  Aggregate Report
 
 
from the .jtl results file. 

There is also  Merge Results   
tool which can be used for 2 test runs comparison which can be invoked from
the JMeterPluginsCMD Command Line Tool as well. 

Both the tools can be installed using  JMeter Plugins Manager

Re: using the same user for all iterations

[glin...@live.com]

You can do this using one of  JSR223 Test Elements
   or 
__groovy() function
  , the
relevant code would be something like:


> new File('test.csv').readLines().get(ctx.getThreadNum())

where *ctx* stands for  JMeterContext
  
class instance.

Re: Multipart/form-data request manually with JSF viewstate

[glin...@live.com]

Instead of copying and pasting the file contents into the .jmx script itself
you can use  __FileToString() function
   which
reads the file from file system. This approach is way more robust and  VCS
  -friendly. 

You can also check out  Testing REST API File Uploads in JMeter
 
 
for an example of manually building a file upload request.

Re: Jmeter sample count

[glin...@live.com]

You are *not* sending 1 request per 1 second, JMeter tries to send requests
as fast as it can for 15 minutes and the number of threads will vary
depending on the response time. 

The only way of getting exactly 900 hits in your setup is placing your
request under a  Throughput Controller

 
, choose "Total Executions" mode and set "Throughput" to 900. 

If you additionally want to limit JMeter's throughput to 1 request per
second you can achieve this in 2 ways:

 1. Using  Constant Throughput Timer

  
and configure it to send 60 samples per minute

 2. Using  Throughput Shaping Timer
   which is more
advanced and under some conditions precise version of the Constant
Throughput Timer using Start and End RPS as 1 and 900 seconds as duration.
You can install Throughput Shaping Timer using  JMeter Plugins Manager

Re: Download

[glin...@live.com]

The download itself is being performed by the  HTTP Request
  
sampler, if you additionally want to save the file somewhere to your local
file system you can add  Save Responses to a file

  
listener *as a child * of the relevant HTTP Request sampler and configure it
like:

Filename prefix: full or relative path to the file where you want response
to be stored in

If you want to download only a single file with a single thread (virtual
user) in a single loop - tick "Don't add number to prefix" and "Don't add
suffix" boxes. 

See  Performance Testing: Upload and Download Scenarios with Apache JMeter

  
article for more information if needed

Re: ID

[glin...@live.com]

Your "ID" value is utterly like to be a  GUID
   so you can
extract it using  Regular Expression Extractor
   configured
like:

1. Reference Name: anything meaningful, i.e. *id*
2. Regular Expression:
*([A-Fa-f0-9]{8}[\-][A-Fa-f0-9]{4}[\-][A-Fa-f0-9]{4}[\-][A-Fa-f0-9]{4}[\-]([A-Fa-f0-9]){12})*
3. Template: *$1$*
4. Match No: if you have >1 IDs in the response and you would like to have
them all - use *-1*. If you want a random one - use *0*. If you want the
first one - use *1*, etc. 

See  Using RegEx (Regular Expression Extractor) with JMeter

  
article for more information if needed.

Re: Which Files/Directory contains the View Tree Results data

[glin...@live.com]

If you run your test in GUI mode - by default the results are being kept in
memory (unless you specify something in "Write Results To" section. 

If you run your test in non-GUI mode by default JMeter doesn't store
response data, it intentionally discards the data to avoid high disk IO
which may have negative impact on your test. However you can enable it by
applying custom  Results File Configuration

  
to wit:


> jmeter.save.saveservice.output_format=xml
> jmeter.save.saveservice.response_data=true
> jmeter.save.saveservice.samplerData=true
> jmeter.save.saveservice.requestHeaders=true
> jmeter.save.saveservice.url=true
> jmeter.save.saveservice.responseHeaders=true

Also be aware that you can test your Regular Expressions, CSS/JQuery
Expressions, JSON Path Expressions, etc. directly in the  View Results Tree

  
listener, just select something different from "Text" dropdown. See  How to
Debug your Apache JMeter Script
  
article for more information on the approach.

Re: JMeter recording

[glin...@live.com]

 1. You don't need to record any calls to images, scripts, styles, fonts,
etc. you should configure JMeter to retrieve all embedded resources from the
page and use concurrent thread pool of 4-6 threads for fetching them as this
is something what real browsers do in the  HTTP Request Defaults

 
.  You should also exclude requests which belong to external domains so your
test would focus only application under test and not include any stuff from
i.e. Google, Youtube, whatever. See  Web Testing with JMeter: How To
Properly Handle Embedded Resources in HTML Responses

  
for more details.

 2. You can use  Debug Sampler
  
or  Debug PostProcessor

 
. You can also print variables values to /jmeter.log/ file using  __logn()
function   

 3. The question is not clear. 
 4. Well-behaved JMeter test (assumes you handle embedded resources like
described in point 1, use  HTTP Cache Manager

  
to represent browser cache, use  Parallel Controller

  
to represent JavaScript calls, etc) should produce the same response time as
real browser does.

Re: ServletConfig has not been initialized

[glin...@live.com]

1. Regarding "I have no way to prove this" - actually you do, you can
configure JMeter to save request and response details by adding the next
lines to /user.properties/ file:


> jmeter.save.saveservice.output_format=xml
> jmeter.save.saveservice.response_data=true
> jmeter.save.saveservice.samplerData=true
> jmeter.save.saveservice.requestHeaders=true
> jmeter.save.saveservice.url=true
> jmeter.save.saveservice.responseHeaders=true

and restart JMeter to pick the changes up. Once your test will be finished
you will be able to open the .jtl results file with  View Results Tree

  
listener and inspect request and response details. It will show whether your
regular expression extractor works or not as well. 

 2. If request in real browser is successful and request by JMeter is not
there should be something different. Compare requests which originate from
JMeter and the real browser using a sniffer tool like  Wireshark
   or  Fiddler  
, you should be able to detect differences by inspecting HTTP packets. It
might be the case you need to correlate not only the form id, but few more
parameters. As a workaround you can try an alternative way of recording a
JMeter test which can export recorded requests in SmartJMX mode
automatically detecting and dynamic parameters and creating regular
expression extractors to handle them See  How to Cut Your JMeter Scripting
Time by 80%
  
article for more details. 

 3. Last by not least: make sure to add  HTTP Cookie Manager

  
to your test plan, it automatically handles cookies which might be a
showstopper for web applications which rely on them.
