Re: JMeter from time to time doesn't calculate regular expressions
for some threads
It is very difficult to diagnose what appears to be a transient issue,
let alone fix it. I think I can guarantee that Jmeter does NOT have a
setting/configuration that introduces random problems to occur at
random times.
In every case that I have found the regular expression not working, I
have looked carefully at the content and found my mistake every time.
I would bet that it isnt finding a match because there is no match.
What you need to do is put a 'View Results Tree' on the http sampler
that you want to match the regular expression and run the test cycle.
When the "mis-match" occurs (the listener will keep a full history of
all the pages fetched"), copy the Result Data to a file and then run
the exact same regular expression over it using Perl 5.003. The same
thing should happen.
If the regular expression works in Perl, then there is cause to
investigate to the next level. If it doesnt, then either the page
content is not what you are expecting, or you need to revise your
regular expression.
BTW, I say Perl 5.003 becuase this is the equivalent regular
expression engine that Jmeter uses. If you are not too familiar with
Perl, then here is an example program to give you a jump start
assuming that you saved the page content as "page.html":
#!/usr/bin/perl
# open file for reading
open(IN, "page.html") || die "unable to open file";
# Run through each line looking to match the regular expression
# Note that if you use brackets (), the the results will be found
# in $1, $2 etc. E.g. $Line =~ /contentId=(\d+)/ then you could
# write in the if statement $contentId = $1;
while($Line = <IN>) {
if($Line =~ /<reg exp here>/) {
print "Found Match!";
}
close(IN);

Re: JMeter from time to time doesn't calculate regular expressions
for some threads
Posted by Craig Palmer <cr...@peace.com>.
Hmmm, OK - looking at the regexp extractor code, there is some
debugging, but I dont think it will be useful enough for this purpose.
It would be simple to temporarily add more though.
I havent had any problems to date with it but I have only run up to 10
threads. Today I'll be pushing it to around 400 threads across a
couple of remote servers. I do a lot of regular expression parsing
across some large and complex html pages. I'll pay particular
attention to the correctness today and see if I have any issues.
I think the key thing is to prove that the regular expression engine
should have picked up the match (such as using perl as mentioned) and
that there wasnt some other issue at hand. You need to isolate the
problem down first and be certain of the exact inputs.
Will hopefully touch base later with my results.

Hi Shawn,
did my version or the nightly build solve this issue? Did you get past
this roadblock? I want to make sure this issue is completely cleared
before we do the next release -- which should be pretty soon.

Re: JMeter from time to time doesn't calculate regular expressions
for some threads
Posted by Jordi Salvat i Alabart <js...@atg.com>.
Strange.
I just downloaded it (jakarta-jmeter-20040209) and tried: it works well
both with jdk 1.3.1_07 and 1.4.2_02 (on Debian Unstable, but I don't
believe this matters to this issue).
Q: Did you also download the libraries? If you didn't, try it: Some of
those in JMeter 1.9.1 may be obsolete, I can't be sure.
Q: Is there anything in the CLASSPATH environment variable before you
start JMeter? In particular: is any version of the ORO libraries listed
there?

Just found the bug just by inspection. My apologies: my earlier review
was incorrect. I'll fix it now. You'll need to download a nightly or
(better, given your experience with nightlies) build from CVS. Or, of
course, wait for the next release, which should happen sooner than
later.

Re: JMeter from time to time doesn't calculate regular expressions
for some threads
Posted by Jordi Salvat i Alabart <js...@atg.com>.
Just found the bug just by inspection. My apologies: my earlier review
was incorrect. I'll fix it now. You'll need to download a nightly or
(better, given your experience with nightlies) build from CVS. Or, of
course, wait for the next release, which should happen sooner than later.

Salut,
Jordi.

RE: JMeter from time to time doesn't calculate regular expressions for some threads
Posted by Vladimir Tsygankov <Vl...@contera.sp.ru>.
Hello, colleagues,
Im returning to the problem of Regular expression problem for many
threads.
Maybe that problem has been already fixed but we could not check that.
Unfortunately nightly builds dont work for now (they even cant perform
any request from my tests) we tried 4 last builds (02/05/2004
02/08/2004).
Therefore we tried to clear out what was the problem under release of
JMeter 1.9.1 (08/17/2003).
As we understand regular expression function is called from JMeter
program but doesnt find necessary string on correct server page for
some threads. The most terrible is that happens occasionally (for any
thread. Sometimes it doesnt happen at all).
Attached file contains more information about texts of requests and
answers for them which we copied from JMeter's "View Result Tree"
element. We saved it for bad and good thread.
Could you help us please?
Thanks in advance,
Vladimir

Hi Shawn.
There was a bug (long since fixed) that may cause this effect. Which
version are you using? Could you try a nightly build?

RE: JMeter from time to time doesn't calculate regular expressions for some threads
Posted by Shawn Elliott <sh...@gotocme.com>.
I too have had problems with the regular expression not picking up
matches. I have closely inspected the response page and it should have
picked it up. Though I have not logged it out to a file to see exactly
what it is picking up. (Will do that today)
Another piece of information is that the regular expression seems to not
match correctly at a higher rate when I have a single thread that is
looping, opposed to multiple threads not looping.
Furthermore I have 4 thread groups each running a regular expression...
Example
Thread Grp 1: NumofThreads=1, Loop=10
Thread Grp 2: NumofThreads=1, Loop=10
Thread Grp 3: NumofThreads=1, Loop=10
Thread Grp 4: NumofThreads=1, Loop=10
Results in the regular expression not matching anything, more than the
following scenario
Thread Grp 1: NumofThreads=10, Loop=1
Thread Grp 2: NumofThreads=10, Loop=1
Thread Grp 3: NumofThreads=10, Loop=1
Thread Grp 4: NumofThreads=10, Loop=1
.... writing this email just made me think of something...
Each regular expression is saving its result to a variable defined in
the 'User Parameters' is this parameter shared between all the
threads?? There for the expression is just over writing the other
threads value??

expressions for some threads
It is very difficult to diagnose what appears to be a transient issue,
let alone fix it. I think I can guarantee that Jmeter does NOT have a
setting/configuration that introduces random problems to occur at
random times.
In every case that I have found the regular expression not working, I
have looked carefully at the content and found my mistake every time.
I would bet that it isnt finding a match because there is no match.
What you need to do is put a 'View Results Tree' on the http sampler
that you want to match the regular expression and run the test cycle.
When the "mis-match" occurs (the listener will keep a full history of
all the pages fetched"), copy the Result Data to a file and then run
the exact same regular expression over it using Perl 5.003. The same
thing should happen.
If the regular expression works in Perl, then there is cause to
investigate to the next level. If it doesnt, then either the page
content is not what you are expecting, or you need to revise your
regular expression.
BTW, I say Perl 5.003 becuase this is the equivalent regular
expression engine that Jmeter uses. If you are not too familiar with
Perl, then here is an example program to give you a jump start
assuming that you saved the page content as "page.html":
#!/usr/bin/perl
# open file for reading
open(IN, "page.html") || die "unable to open file";
# Run through each line looking to match the regular expression
# Note that if you use brackets (), the the results will be found
# in $1, $2 etc. E.g. $Line =~ /contentId=(\d+)/ then you could
# write in the if statement $contentId = $1;
while($Line = <IN>) {
if($Line =~ /<reg exp here>/) {
print "Found Match!";
}
close(IN);
