tag:old.nabble.com,2006:forum-2584Nabble - Grinder2009-12-15T15:09:52ZThe Grinder is a JavaTM load-testing framework. The Grinder makes it easy to orchestrate the activities of a test script in many processes across many machines, using a graphical console application. Test scripts make use of client code embodied in Java plug-ins. Most users of The Grinder do not write plug-ins themselves, instead they use one of the supplied plug-ins. The Grinder comes with a mature plug-in for testing HTTP services, as well as a tool which allows HTTP scripts to be automatically recorded.

<br><br>Not sure whether there is any forum separate for Ground Report. If anyone aware of one please let me know. By any chance, if anyone in this forum knows how to use Ground Report please help....
<br><br>I was able to upload the grinder data to the db successfully. But when I try to generate the report, I get, "No data found for specified Load Run". Not sure, what I am doing wrong. I have all the default properties for Ground report except for the below:
<br><br>commented out the foll. because I first want to run report for just one run
<br>#loadRunList = [1,2]
<br>commented out pagePair because I am testing REST calls and there are no pages.
<br>#pagePair = [100,200]
<br>Got the loadRun number from raw_data_http table.
<br>loadRun=2
<br><br>Thank you

</div><br>Mark,
<br><br>That's surprising, but good to know. I've made a note to update the FAQ.
<br><br>Also good to see people picking up the Jython 2.5 support. I'm pretty

<br>Let me know of other problems you find.

<br>Asunto: No space left in the heap when running tests for an https service
<br><br>Hi,
<br><br>We are using grinder to test a https service and we have noticed that after
<br>having our grinder script running for a long while (12 hours or more) the
<br>process dies saying that no space was left on the heap.
<br><br>We have been taking several snapshots of the heap contents when while the
<br>process was running and noticed that the amount of instance of some classes
<br>related to ssl are growing and growing until there is no extra space left.
<br><br>Find below the name of the classes with more instances in the heap:

<br>Leak of CachingSSLContextFactory occurs when setKeyManagers, setKeyStore,
<br>or setKeyStoreFile is called due to the previous instance not being

<br> [junit] at HTTPClient.TestCookie.testParse(TestCookie.java:76)
<br> [junit]
<br><br>*What is Problem?
<br>// Time zone offset is considered in the following:
<br> final Cookie[] cookies2 =
<br> Cookie.parse("foo=bah;path=lah;expires=Sat, Mar 25 16:53:28 GMT
<br>2006", m_roRequest);
<br><br>// But, time zone offset is not considered in the following:
<br> final Date result = df.parse("25/03/06 16:53:28");
<br><br>// So, this parse result changes by the user's locale.
<br>// And the test fails.
<br><br>*What Should You Do?
<br>Set java.util.TimeZone object to java.text.DateFormat object.
<br><br>*Patch

<br><br>Looks like it was something to do with the network and not with the script. When I tried it from a different machine which was internal, it worked fine.

Launch application using a JNLP url.<br>
2. Download all needed jar files on to the client machine either through Jinitiator or on its own.<br>3. Run the main Java file and launch a Java thick-client based browser of its own which will utilize all client-side jar files.<br>
4. After application login, the interaction keeps occurring using the Java thick-client browser which internally utilizes RMI to interact with server.<br><br><b>**Additional information:</b> We have configured client-side launching temporarily in a way where we have downloaded all jar files into a folder (which application usually downloads), setup classpath and run the main class making calls to all class files so that application launch process happens in traditional java application launch mechanism (similar to java hellowworld).<br>
<br>Considering this situation, please let us know steps to take and accomplish performance testing using <b>Grind 3</b>. We will be glad to take up assistance we would receive for accomplishing above tasks as a Professional support based on our Budgets so that we would position this in our customer engagements.<br>
<br>Thanks for any advice we could receive.<br><br>Best Regards,<br>Chaitanya<br>

I wanted to see If I can put all my utility files used by various
scripts into a JAR file and set the CLASSPATH using
grinder.jvm.classpath=myjar.jar so that any imports done in the scripts
will be able to find the module. The idea is to not use directory paths
in the script itself so they can be moved from place to place.<br>
<br>
<br>
A standalone Jython script works fine when I export CLASSPATH.<br>
<br>
export CLASSPATH=myjar.jar<br>
<br>
Jython:<br>
import mymodule (which is in myjar.jar)<br>
<br>
mymodule.method -- works fine.<br>
</div>

<br>
What version of Jython did you use? A quick experiment shows that the
above works with Jython 2.5.1, but not Jython 2.2.1. The default
version of Jython bundled with The Grinder is Jython 2.2.1.<br>

Doing the same in grinder does not work even if I use
grinder.jvm.classpath = myjar.jar or even just setting CLASSPATH <br>

java -cp $CLASSPATH net.grinder.Grinder<br>

You can use Jython 2.5.1 with the latest version of The Grinder - see <a href="http://grinder.sourceforge.net/g3/jython-2-5.html" target="_blank" rel="nofollow">http://grinder.sourceforge.net/g3/jython-2-5.html</a><br>

<br><br>I tried it from 2 machines. On one machine, each get call takes a long time, around 2 minutes for 1 group(16 get calls) and doesn't get recorded in the console. I think it's just too low to show in the graph? On another machine with single url call each as a transaction is run, it runs around 300-400 transactions per second. When run the following script it runs only 3-4 transaction per second which is 16*4=64 urls. It gets recorded in the console. Still seems to be slow. Does that make sense?
<br><br>Thank you
<br>Jo

I wanted to see If I can put all my utility files used by various
scripts into a JAR file and set the CLASSPATH using
grinder.jvm.classpath=myjar.jar so that any imports done in the scripts
will be able to find the module. The idea is to not use directory paths
in the script itself so they can be moved from place to place.<br>
<br>
<br>
A standalone Jython script works fine when I export CLASSPATH.<br>
<br>
export CLASSPATH=myjar.jar<br>
<br>
Jython:<br>
import mymodule (which is in myjar.jar)<br>
<br>
mymodule.method -- works fine.<br>
</div>
</blockquote>
<br>
What version of Jython did you use? A quick experiment shows that the
above works with Jython 2.5.1, but not Jython 2.2.1. The default
version of Jython bundled with The Grinder is Jython 2.2.1.<br>

<br>Summary: HTTP filter generates invalid Jython code for Jython > 2.5.0
<br><br>Initial Comment:
<br>Hi,
<br><br>The HTTP filter of TCPProxy in Grinder 3.3 generates codes that look like:
<br> headers0= \
<br> ( NVPair('Accept', '*/*'), )
<br><br>This code does not work with Jython > 2.5.0 because tuples in Python are immutable,
<br>which in turn means values in a tuple must also be immutable.
<br><br>Using lists instead of tuples resolves this issue; the result will look like:
<br> headers0= \
<br> [ NVPair('Accept', '*/*'), ]
<br><br><br>----------------------------------------------------------------------
<br><br>>Comment By: Philip Aston (philipa)
<br>Date: 2009-12-10 22:37
<br><br>Message:
<br>Generated scripts fail under 2.5, and the workaround works, but not for the
<br>reason suggested in the Details field. It is fine for a Python tuple to
<br>contain a mutable value.
<br><br>The code quoted in the Details works fine under 2.5. I think the bit of
<br>the script you meant to quote was in fact something like...
<br><br>connectionDefaults.defaultHeaders =\
<br> ( NVPair('Accept-Language', 'en-gb,en;q=0.5'),
<br> NVPair('User-Agent', 'Mozilla/5.0 (X11; U; Linux i686; en-GB;
<br>rv:1.9.0.15) Gecko/2009102815 Ubuntu/9.04 (jaunty) Firefox/3.0.15'), )
<br><br>Please confirm.
<br><br>Jython 2.5 has problems in mapping tuples to the Java arrays when the
<br>attribute syntatic sugar is used in place of a setter. On the other hand,
<br>this works:
<br><br>connectionDefaults.setDefaultHeaders(
<br> ( NVPair('Accept-Language', 'en-gb,en;q=0.5'),
<br> NVPair('User-Agent', 'Mozilla/5.0 (X11; U; Linux i686; en-GB;
<br>rv:1.9.0.15) Gecko/2009102815 Ubuntu/9.04 (jaunty) Firefox/3.0.15'), ))
<br><br>I've done a quick query against the Jython bug database and found nothing.
<br>We need to contact the Jythonista's and see whether they can explain
<br>whether this change in behaviour from 2.2.1 is by design or not.

Use whichever is more convenient for you. The HTTPRequest object is
just a way to manage a set of default settings. In the code below, it
looks like the second is more appropriate.<br>
