How to suppress JMeter deprecated warning

[Tong Sun]

Had meant to ask for quite a while -- how to suppress JMeter deprecated
warnings like the following,

"WARN StatusConsoleListener The use of package scanning to locate plugins
is deprecated and will be removed in a future release

etc? Found a different one BTW at
https://stackoverflow.com/questions/59733770/how-to-get-rid-of-warning-nashorn-engine-is-planned-to-be-removed-from-a-future

thx

Re: Iteration Number in JSR223 Groovy string

[Tong Sun]

Thanks a lot sir, I really appreciate your help and your get-to-the-bottom
attitude.

Wrapping the resolution in a groovy function is surely a useful trick that
I'll be using a lot.

Thanks again

[Tong Sun]

Thanks.

So the root cause is:

Having known that, I still don't quite understand why I'm getting zeros.
My actual groovy string is:

"ThreadGroup: ${__threadNum}, Iteration Number:
${__V(__jm__${__threadGroupName}__idx)}"

Now, suppose `${__threadGroupName}` returns `My_TG`, then the
`${__V(__jm__${__threadGroupName}__idx)}` will become
`${__jm__My_TG__idx}`, right? Then why ${__threadNum} gives none zero,
while ${__jm__My_TG__idx} always gives zero pls? They are the same built-in
JMeter variables and should behave the same way, right?

Iteration Number in JSR223 Groovy string

[Tong Sun]

JMeter has a built-in variable ${__jm__Thread Group__idx} to retrieve the
current iteration, and I want to replace the `Thread Group`
using ${__threadGroupName}. So this comes natural to me:

"Iteration Number is ${__V(__jm__${__threadGroupName}__idx)}"

But when I try it, I always get "0".

What's wrong with it and what's the fix pls? thx

Re: jmeter-5.6.3 and response body viewing

Yeah, our company is using a rather old jmeter-5.4.3.

Thanks for the quick fix.

jmeter-5.6.3 and response body viewing

[Tong Sun]

Hi,

I tried to upgrade to jmeter-5.6.3 but found that its response body is
showing in a single line, ie, no automatic word wrapping any more.

This is very inconvenient for us as all our normal return data are huge
when returned correctly while being short when there's something wrong.
Seeing them in the single line, I lost the sense of whether the response
was good or bad.

Any way to turn the automatic word wrapping back on please?

Will JMeter load its plugins/libs repeatedly

[Tong Sun]

Will JMeter load its plugins/libs only at start up, thus having no impact
during the test, or plugins/libs might somehow need to be loaded again (and
again) during the test?

Thanks

Re: JMeter timer scope strange behavior

[Tong Sun]

TBH, reading your latest input and trying to figure out the problem is
hard, as the previous context is lost.
IMHO, you'll get better chances to get an answer if you articulate clearly
your whole/current situation again, without missing anything, but without
repeating irrelevant parts.

Please be specific how you are doing the S1 thread load control, and
be more specific about what you want -- *single thread* executed once
every 5 minutes? You must be doing something wrong, as it is a very
basic setup.

Hi,

According to JMeter doc:

JMeter also supports paths relative to the directory containing the current

 However, when I tried to put "~/" before


   - my include script, or
   - my CSV data file


Both cases would fail, with the latter giving the error messages of:

java.lang.IllegalArgumentException: Could not read file header line
for file ~/Data/xxx.csvat
org.apache.jmeter.services.FileServer.reserveFile(FileServer.java:283)

~[ApacheJMeter_components.jar:5.5]at
org.apache.jmeter.control.GenericController.fireIterationStart(GenericController.java:399)
~[ApacheJMeter_core.jar:5.5]


I'd really love to have "~/" to cover the above two cases as well.

Would that make sense? thx.

Is it possible to use variables as the choice of include controller?
I.e., what jmeter script to include is based on the content of the variable.

However, I tried it (in JM5.5), but wasn't able to make it work:

query = '''select ${column} from ${table}'''
column = "name"
table = "customers"

log.info("${query}")
log.info('=${__evalVar(query)}=')


but the output I got is:

select ${column} from ${table}==

Thanks Dmitri.

By  *42* you meant the "5L" in above jsr223 code, or there is another line?

Any ways to change the request response time?

[Tong Sun]

Hi,

Is it possible to change the request response time (via jsr223)?

I need to fetch one important number, and instead of trying to create a way
to report it somehow, I'm thinking the easiest way to report and track it
is to set the fetched number as the request's response time.

thanks

Re: jMeter script does not respond

Hi Dmitri,

By "adding to the HTTP sampler label", do you mean its "Name"?

Else, how to add to the HTTP sampler label?

how to change the user defined variable?

[Tong Sun]

Hi,

How do you change the user defined variable?

The same question has been asked before, like under
https://guide.blazemeter.com/hc/en-us/articles/207421395-Using-User-Defined-Variables,
but I found no good answers.

Unlike placing them under Thread Group or Sampler, I need to

- define UDV under the Test Plan, and use those UDVs to
parameterize/control my Thread Group.
- and change them after UDV definition but before applying to the Thread
Groups

For e.g., pseudo code:

if isSpecifyingThreadLifetime then LoopCount = 100

How can I do that? Thx!

jmeter influxdb backend listener and querying

[Tong Sun]

So I added the standard jmeter influxdb backend listener, with default
setting of

percentiles: '90;95;99'

and I can query the influxdb backend DB using:

SELECT mean("pct90.0") FROM "$measurement_name"

The question is, how to query its *mean *values?
I tried the following but failed:

SELECT mean("pct50.0") FROM "$measurement_name"

Re: Is this a bug? Cookies are in the Request Body...

[Tong Sun]

I'm so curious that I gave it a try myself, but I don't see the reported
problem. Everything looks fine to me.

One thing though, I put the Cookie Manager within Thread Group, not outside
of it and under the Test Plan.

If trying that still won't work for you, I'm afraid that you need to post
your simple .jmx file somewhere,
and tell us which JMeter version that you're using.

Yep, that's exactly what I meant, the lines should be connected by straight
lines, the breaking-up parts mean missing store values.

OK. I do see other of my simple tests having continuous connected straight
lines (which should rule out JVMs setup problem I suppose).
And I'll look into the other methods you mentioned, like looking at the GC
values on the receiving server. TBH, these are all new to me,
if there are any reading materials / links that I can refer to, that'll be
appreciated.


BTW,

I'm not using
https://github.com/mderevyankoaqa/jmeter-influxdb2-listener-plugin#compatibility
which supports InfluxDB v2.x only (mine is 1.8, and it is not supported)

The one that I'm using is
org.apache.jmeter.visualizers.backend.influxdb.HttpMetricsSender,

Maybe it too, after five errors the import will be stopped.
If it does, there should be a log somewhere, I'll check carefully for it

Hmm... No, it's in single thread, with a single user. Here is the log

Repeatedly trying to load included modules

[Tong Sun]

Hi,

Please take a look at my logs:
https://www.diffchecker.com/7mROaakN

Same script, one is all-in-one, the other (on the right) uses the include
controller, which apparently repeatedly trying to load included modules, as
the following two lines have been repeated 5 times:

INFO o.a.j.c.IncludeController: loadIncludedElements -- try to load
included module: F_Thread_Group.jmx
INFO o.a.j.s.SaveService: Loading file: F_Thread_Group.jmx
INFO o.a.j.c.IncludeController: loadIncludedElements -- try to load
included module: F_google-reqs.jmx
INFO o.a.j.s.SaveService: Loading file: F_google-reqs.jmx

As the ThreadGroup is started with number=1 threads=1

I'm wondering

- why the repeatedly load attempts, and
- if this is a known issue

or something wrong with my script, in which case I'd be happy to publish
them somewhere.

Revisiting this old thread yet again for jmeter v5.5.

Please check out the test-fragment.jmx file at:

https://pastebin.com/iTzRamb4

Here is the steps how I save it:

- select all steps under the test fragment
- right click and select "save as test fragment"

What you get should be the same as mine, if you're using jmeter v5.5.

However, the problem is, when I open and save it again in JMeter, I'll get
an almost-empty file instead.

Any help please?

JMeter Modularisation Strategy

[Tong Sun]

Hi,

How do you modularize your JMeter?

I'm thinking that the Include Controller is better than the Module
Controller.

However, for using the Include Controller, it bears the problem of how do
you include other files?

I'm thinking that relative paths are better than absolute paths, as it'll
be more portable.
Also, the Include Controller "*does not support variables/functions in the
filename* field". So it seems that if using the Include Controller
then the relative
paths is the *only *option.

However, that poses another problem that,

jmeter -t path/to/myscript.jmx

will fail.

So, what's the best JMeter Modularisation Strategy?

This sounds like a very useful feature, but I cannot grasp how to make use

Re: Simulate Think Time

[Tong Sun]

Hi,

Found a problem applying simulated Think Time --


   - I don't want the simulated Think Time be calculated/included in my
   response time
   - So I put it after my request, not under it
   - However, I put only one such Think Time but *every *single request is
   now delayed, because it is actually *at the thread group level*.
   - That in turn caused a bigger problem for me, as I only want Think Time
   delay *after *each of my *transactions*, but not the requests
*within  *those
   transactions.
   - I.e., if a single click of "submit" contains several requests, I want
   those requests executed without any delay, but only do Think Time after
   all those requests are done.

How to achieve all of the above please?

JMeter standalone comments

[Tong Sun]

Hi,

I know each item (control, request, etc) has a comment field. I view it as
putting comments to the end of line in the source code.

Is there any way to add a standalone comment, by (ab)using some
*simplest *control?
Kind of like putting comments on the line of its own in the source code.

JMeter Best Practices - Sharing variables between threads and thread groups

[Tong Sun]

Hi,

In the JMeter Best Practices:
https://jmeter.apache.org/usermanual/best-practices.html

It says

To "Share variables between threads and thread groups",

there are various options:

   - Store the variable as a property - properties are global to the JMeter
   instance
   - Write variables to a file and re-read them.
   - Use the bsh.shared namespace - see above
   
   - Write your own Java classes


Using the bsh.shared namespace seems to be an appealing option, However,
the BeanShell scripting is *deprecated*, so here is my question:

Would the following still be the recommended best practices?

The sample .bshrc files contain sample definitions of getprop() and
setprop() methods.

Another possible method of sharing variables is to use the "bsh.shared"
shared namespace. For example:

if (bsh.shared.myObj == void){

// not yet defined, so create it:

myObj = new AnyObject();

}

bsh.shared.myObj.process();

Rather than creating the object in the test element, it can be created in
the startup file defined by the JMeter property "beanshell.init.file". This
is only processed once.


If not, is there any groovy based mechanism that provides the same
functionalities?

Thanks

Re: Help: Unable to connect to MS SQL server DB

Yeah, that proves my doubt that, are you sure using such trustServerCertificate

So, my advice,

- Try connect to your azure Database with MS SQL server client itself using
the SQL authentication (user/password) first
- If it works, replace your jdbc sqlserver connection string with the SQL
authentication (user/password) and try again

View Results Tree Behavior when running from command line

[Tong Sun]

Hi,

Quick question, what would the View Results Tree behavior be when running
from command line?

I had an impression that it won't do anything even if it is enabled, is it
so?

thx!

Easy way to save the req/resp session

[Tong Sun]

Hi,

Say I run my JMeter script using a single user for a single time, is there
any easy way to save the whole session, both the requests and responses,
including the headers, to some file for later inspection?

Re: Simulate Think Time

[Tong Sun]

OMG, JMeter has this thought of and provided long ago but I just never knew
before.

Thanks a lot Malachi !!!

Re: Simulate Think Time

[Tong Sun]

Thanks Dmitri.

We run load tests normally not to reproduce the issue but to simulate the
real world.

As https://www.guru99.com/timers-jmeter.html said,


*In real life visitors do not arrive at a website all at the same time, but
at different time intervals. So Timer will help mimic the real-time
behavior.*

This is a more important aspect to us, but thanks for the input/warning.

Re: Simulate Think Time

Thanks!

What would be the best way to turn those Think Time steps on or off
*together*?

Basically I don't want Think Time at design/debug time but only during
official run. However, it'll be a pain to *turn them on or off* one by one
as this has to be done so constantly and I have many such request steps.

Simulate Think Time

What's the best way to simulate Think Time?

Say I need a random wait time between 2~8 seconds between each of my
transactions, what's the best control to do that?

Thanks!

Re: JMeter 5.4.3 unable to open jmx created in 5.2.1

[Tong Sun]

Interesting. How come it could happen?

I mean, when a script I'm opening is using a plug-in that wasn't yet
installed, JMeter would ask me whether to install it, then install all
the missing components for me. It is not like that for you Steve?

Why two jmeter executables for Linux?

[Tong Sun]

Hi,

Why two pairs of jmeter executables for Linux?

E.g.,

jmeter/bin/jmeter vs jmeter/bin/jmeter.sh
or jmeter/bin/mirror-server vs jmeter/bin/mirror-server.sh

I took a look at jmeter/bin/jmeter vs jmeter/bin/jmeter.sh and found
them quite similar. What's the point of proving two almost identical
scripts? thx

 Hi, Felix

Can you elaborate on how to share a single JDBC Connection between all the
threads pls?

All the threads can share a single CSV input but for them to share a single
JDBC Connection I'm yet to find how.

It'll help to send unique values in the requests from all the threads.

I think in such a situation, the best way forward is to test a (simple
& reliable) public service using JMeter and HP BSM.

If the two still can't agree with each other this way, record the
public service visiting with fiddler. The closer to fiddler's
reporting wins.

Script wide validation

[Tong Sun]

Hi,

I know currently JMeter doesn't have script-wide validation, a feature
available in other testing tools like MS VS, that a single script-wide
validation rule can be used to check every request in the whole script.

This is something I miss moving from  MS VS to JMeter. Since all our
returns are json based, and all have a unified way to report errors, a
single script-wide validation rule makes perfect sense in this case.

So, what options/workarounds do I have? thx

Thanks a lot for the quick response and fix.

I've tried building JMeter from source before and wasn't successful.

Here is one way you can do a quick test yourself,

- Find a smallest JMeter file and open with a text editor
- Make any tag imbalance, by introducing a typo or removing the end tag

Moreover, when it happens, It's staying on top of everything, making it

I tried to hand-craft my jmeter script the way I want externally using a
tex editor, but this is what I got so far, and I haven't figured out why
yet. The physical structure itself pass xml validation but seems it is a
logical error. I was planning to do trial and error to pinpoint where the
problem is, but Felix if you don't mind taking a quick look for me, I'll be
very grateful.

Thanks Felix, for your effort in trying to help in the previous case, and
sent that patch.

Ok, if the option to turn off the splash screen is not acceptable, Felix,
would you make another PR that it ends in an earlier spot please?

The current situation is that, whenever Jmeter has finished load scripts
and has found a start up problem, the pop up error windows will be behind
the splash screen. I don't mind the splash screen normally, but I think
blocking the error windows is something not intended by design, and should
be fixed.

Thanks

[OT] Associate JMeter with .jmx files under Mac

[Tong Sun]

Hi,

In windows' term, associating JMeter with .jmx files means
double-clicking .jmx files in file explorer will launch jmeter to open
the file.

I'd assume it's a quite common request under Mac as well.
Has anybody managed to do that?

thx

Thanks glinius, that actually answered my next question, how to
overcome the failed tests.

So, to summarize it up,

- use the tar.gz download as suggested by Felix
- and build with above command to avoid the failed tests

Now I have a jmeter-5.4.1-SNAPSHOT.jar file.

So the next question regarding building JMeter from source -- how to
make use of the build result?

I did

rsync -ua /Applications/apache-jmeter-5.3/bin/
/Applications/apache-jmeter-5.4/bin/

and copied my build/libs/jmeter-5.4.1-SNAPSHOT.jar as
/Applications/apache-jmeter-5.4/bin/ApacheJMeter.jar

but when invoking it with,
/Applications/apache-jmeter-5.4/bin/jmeter

I got
no main manifest attribute, in
/Applications/apache-jmeter-5.4/bin/ApacheJMeter.jar

thanks

JTL file for PerfMon Metrics Collector for JMeterPluginsCMD

[Tong Sun]

Hi,

JMeterPluginsCMD supports PerfMon Metrics Collector for generating
graphs out of JTL files, as per the doc.

But I don't know what its JTL file should be in order to get it working.

Anyone can help please?

Bug? JMeter is not using the default groovy

[Tong Sun]

Hi,

I've already set the default groovy version, but it seems that JMeter
insists something of its own:

So how to tell my JMeter not to use groovy v3.0.3 but v2.4.12?

Note this only happens when running JMeter in -n(NON_GUI) mode. GUI
mode is somehow fine.

Re: Mark error in JSR223 steps

[Tong Sun]

Hmm,

I've put

SampleResult.with {
successful = false
responseCode = "500"
responseMessage = "some error"
}

into my catch section, but they are still green and correct (even
error is caught) viewed in Result Tree.

I also tried to use

SampleResult.setSuccessful(false)

but that didn't work either -- itself generated another exception.

So do I have to `new` a SampleResult before making use of the class?
If so, how can JMeter know to use my own newed SampleResult as the result?

Mark error in JSR223 steps

[Tong Sun]

Hi,

My JSR223 steps have problems, some even have exceptions, but viewing
from View Result Tree, they are all green and correct.

How to mark those JSR223 steps that have problems red and failed?

I tried to throw an exception, but that killed the whole thread.

thx

Yeah, exactly in the JSR-223 scripts.

I put merely

org.codehaus.groovy.runtime.StackTraceUtils.sanitize(new
Exception(e)).printStackTrace()

before but nothing get printed in log, so I changed to log.info instead.

You meant building one single fat jar to include them all, all those
third-party jar files?

Best approach to use groovy/grapes cache jar files

[Tong Sun]

Hi,

- Most people would have some Java code to support JMeter test scripts.
- Those Java code would most probably need to be built on third party libs
- Those third party libs are downloaded and cached automatically by
groovy/grapes in its cache.

So the question is what is the best approach to use groovy/grapes
cache jar files?

I did some research but didn't find much good answers, the best one I found is

https://stackoverflow.com/questions/59398827/

which is as simple as providing JMeter a grapeConfig.xml file. But
that's all within the conversation -- I don't know where to find such
grapeConfig.xml, or how to generate one.

Anyway, the question/goal is what is the best approach to use
groovy/grapes cache jar files. thx

Sorry I can't get it to work. I'm getting

java.lang.IllegalArgumentException: File 1 must exist and be readable

It must be something simple but I just can't figure it out now. So
here is my code:

-
CsvFile = "Test.csv"

log.info("CsvFile: ${CsvFile}")
props.put("CsvFile", CsvFile)
log.info("CsvFile: ${__P(CsvFile)}")
setProperty("CsvFile", CsvFile)
log.info("CsvFile: ${__P(CsvFile)}")
-

And for that, I'm getting:

2020-12-16 16:48:49,970 INFO o.a.j.p.j.s.J.init: CsvFile: Test.csv
2020-12-16 16:48:49,970 INFO o.a.j.p.j.s.J.init: CsvFile: 1
2020-12-16 16:48:49,970 INFO o.a.j.p.j.s.J.init: CsvFile: 1

What's wrong? Thx!!

Thread Groups based initialization for each thread group

[Tong Sun]

Hi,

I need to do some initialization for each thread group before they
start, by calling several groovy functions.

I know there is a setup thread group, which is run once before all
thread groups, but how can I do setup once for each thread group?

Say for the following groovy script,

---
import C1
import C2
import C3

c1 = C1.init()
c2 = C2.init()
jdbc =C3.getjdbc(c1, c2)
---

how can I call it only once for each thread group?

thx!

Prepare dynamic csv test data in setup thread

[Tong Sun]

Hi,

I want to

- prepare dynamic csv test data in setup thread
- and use the generated .csv data for all other thread groups
- ideally, the name of the .csv is better be changed in the setup
thread as well.

How much of the above steps are possible?

Point 2 & 3 seems to be impossible to me at this point.

There are 2 types of properties which are in use by Apache JMeter ...:

- System Properties
- JMeter Properties

I know one can set a *JMeter* Property via  __setProperty() function,
but it is the "*System* Properties" that I was talking about.

I need to set a system property programmatically *within* JMeter.

thanks

How to set system property within JMeter

Hi,

I need to set a system property programmatically *within* JMeter.
How can I do that?

in
https://www.blazemeter.com/blog/apache-jmeter-properties-customization
the Option 3 is to use JMeter __P, but

It seems that I can only read system property from __P(), but cannot
set it, correct?

This is a valid jmx file, but will turn empty when saved

[Tong Sun]

Hi,

This is my first post here, and I don't know the policy on attaching
files. So I put my file at

https://dpaste.com/F3K6Y7ZV2

It's a valid jmx file (search.jmx), which can be included from e.g.,

https://dpaste.com/DB5TEMNSW

Everything is OK, except that when open the search.jmx file and save
again in JMeter, I'll get an almost-empty file instead, like

http://dpaste.com/ESVT2FWLG

This has been the case for old and current version of JMeter, like
5.2.1 and 5.3.

Please verify.

Thanks
