How to call function for each response

Sean Tiley — 2013-05-22T14:07:36

Hello
I am using grinder 3.11.  I record my tests using the TCPProxy and am
really having no issues.
I have created several functions that I use to validate response sizes,
content type etc and one function to write out the responses.

Up to now when I  want to write out a response for a request, I add the
"saveToHTML" line to each section of the recorded script as below

  def page1(self):
    """GET / (request 101)."""
    result = request101.GET('/fins_enu/', None,
      ( NVPair('If-Modified-Since', 'Wed, 22 Oct 2008 23:41:54 GMT'),
        NVPair('If-None-Match', '\"04d6ec39f34c91:0\"'), ))
   * saveToHTML(result,"Response_Page1") *
    return result


This becomes very tiresome to add this line to each section of the code,
especially when some of the tests have > 50 request/responses.  Very manual
and there must be a better way

So my question is how can I simplify this?
I already have a function that writes out the files, I just need to
understand how to call that function a better way so its not such

How to know the value of grinder.consolePort andheadless console service port value?

Ravi Joshi — 2013-05-19T18:39:02

Hi all,

Till now I am in habit of running Agents in 6372/6373 port. My question is how to know the value of grinder.consolePort andheadless console service port value?

 
I found that after starting console in headless mode, it shows below log-
2013-05-19 23:23:39,870 INFO  org.eclipse.jetty.server.AbstractConnector: Started SelectChannelConnector< at >:6373

Is this 6373 headless console service portor is it grinder.consolePort  ?

I found that in my setup, agent is connected to console on port 6372 and console (which is running in headless mode) is showing 6373 port number. Anybody here, please explain me about it?

The screenshot is attached for more information.

So what are the ways to know the value of both?

Abnormal behavior of Grinder showing nothing inProcess tab

Ravi Joshi — 2013-05-20T19:07:39

Hi all,


I found an abnormal behavior with Grinder console. It is showing nothing in Process tab even agent is connected.

The agent is connected to console and it is showing below message in the terminal-
root< at >laptop:~# /opt/grinder_agent/bin/agent.sh 
2013-05-20 21:37:06,100 INFO  agent: The Grinder 3.11

2013-05-20 21:37:06,275 INFO  agent: waiting for console signal

At the same momentnetstat -t is showing me the same info-

but why http://localhost:6373/agents/status is returning [] ? Also there is nothing in Process tab in console. 

The grinder version is 3.11

Unable to run test script to test secure iframe insecure page

Michael Thomsen — 2013-05-16T23:33:14

Hello,

 

We are currently trying to test an application that loads a widget in a secure iframe on a secure page.  The problem that we are seeing is that grinder's security certificate isn't valid, so the widget doesn't load returning an 301 Permanently Redirected error.  

 

I tested this another way by starting up the proxy recorder, specifying to record over https, which it can proceed through the https pages and record as expected, until it gets to the page that loads the widget in the secure iframe, then in chrome I get 

 

"Error 113 (net::ERR_SSL_VERSION_OR_CIPHER_MISMATCH): "

 

In the test script's properties for the JVM arguments I tried adding the trust store properties (after adding the key to the trust store via keytool):

-Djavax.net.ssl.trustStore=C:/Progra~1/Java/jdk1.6.0_07/jre/lib/security/cacerts -Djavax.net.ssl.trustStorePassword=changeit

 

However that didn't seem to make a difference so I am currently out of ideas.  Has anyone else had any experience with this? Any workaround's?

can't record ssl session

Marc Claeys — 2013-05-14T13:19:14

Hi all,

No matter what option I try I always get:

  def __call__(self):
     """Called for every run performed by the worker thread."""
     # Empty recording!
     pass


I specified the -ssl option (java net.grinder.TCPProxy -http -ssl  -console)
and added HTTPClient-JSSE.jar as first entry in the CLASSPATH.

The whole session works fine (https to a tomcat console) but nothing 
gets recorded.

Anyone to help me out?

regards.

Sending Http req with diffrent-2 IP addresses from anagent

Ravi Joshi — 2013-05-14T06:24:23

Hi all,

From two agents, I can send http request, which will be having diffrenet-2 IP address. The system (which is under test) will treat them as request from different machines. Simple and Okay J

Is there any way to achieve the same scenario (so that request looks like from different machines to the system)?

Thanks and regards

HTTPRequest retry attempts

O'Connor, David — 2013-05-09T12:59:39

Hi,

I'm using grinder-3.4 for load testing. I'm using Test class wrap method to call HTTPRequest class GET method.

For particular tests, after connecting to the server and sending the request, the server fails to respond and closes the connection. It appears the HTTPRequest object reconnects to the server and resends the original request. The HTTPRequest object will re-attempt to obtain a response 2 times (3 attempts in total) before an Exception is raised.

How to know that Test is finished using Grinder RESTservices?

Ravi Joshi — 2013-05-06T10:43:05

Hi all,
 
To know the available workers, I can
get the count of worker array from the /agent/status service. And if the count
is zero, that can solve my purpose. But there are two cases, in which worker
array length is zero-
1.    Agents
are connected but test is not started
2.    Agents
are connected and the test is finished

Because of this ambiguity I am not able to know that whether test is finished
or not. 
 
How to know that Test is finished?

Create dummy database and Json file using Grinder

I need to use it as a Automation tool. So is it possible to create a dummy
database table using Grinder tool and create Json file from that as a
response of Http request using Grinder itself.

Can Grinder overlook ramp up period?

Jai P — 2013-04-18T18:02:52

I have re-written my Loadrunner script in Jython and am load testing with
Grinder. The test works fine when I use threads alone or a combination of
processes and threads split on 2 agents.
When I use processes, I use the following properties:

grinder.processes=5
grinder.runs=0
grinder.duration=900000  #15 min

grinder.processIncrement=1
grinder.processIncrementInterval=24000
grinder.initialProcesses=1
grinder.initialSleepTime=5

Basically, I want to ramp up the # threads over the first 2 minutes of the
test, like I would do in Loadrunner. In my script, I have copied the
example in the Script gallery for thread ramp up as well.
However, at the end of the test, when I analyze the results using
GrinderAnalyzer, I am unable to discard the first 2 minutes since I am only
interested in measuring TPS and response times during steady state. I am
not sure if GrinderAnalyzer questions would be answered in this forum, but
I believe there is a bug when it aggregates results from multiple processes
from 2 different mach

Grinder and OpenTSDB

Rob Schroder — 2013-04-10T19:11:37

Does anyone know of an integration of The Grinder with OpenTSDB? We use OpenTSDB for collecting a ton of metrics. If something already exists, it would be good to know. Otherwise, I'll start looking at what it would take to get response times, along with other metrics, from The Grinder into OpenTSDB.

Calling C++ executable using Java's Runtime

Jai P — 2013-04-05T20:59:41

Following the tips in my previous post "Cython implementation of Loadrunner
based C script to work with Grinder", I re-wrote my C code and compiled it
with "cl" (MSVC 2005) into an exe.

The exe takes 1 argument (int) and based on results obtained from the
server, it will print a success or failure.

Since I want to performance test this with Grinder, I used Java's
Runtime.getRuntime().exec(cmd) to run my exe. Using my custom class, I am
able to increment the integer I need for the argument.

 Sure enough it works as expected for a few inputs, however when I increase
the # threads in grinder, I see a spike in CPU, followed by a modal dialog
box suggesting an issue with the C++ Runtime Library (the error is from the
MSVC 2005 C++ redistributable installed on the test machine to run my exe).

In order to ensure that the exe doesn't hang around, I used taskkill /f /im
<my.exe> to ensure it is killed. With this hack, the test seems to work for
up to 10 threads, but if I increase it beyond that, I then run into

Cython implementation of Loadrunner based C script towork with Grinder

Jai P — 2013-03-28T20:18:25

I have legacy test scripts written in C (not recorded http scripts. In fact
there is no http but just C API) for use with Loadrunner. I would like to
use Grinder instead of Loadrunner.

In order to reuse the test scripts written in C could I wrap them in
Cython? (http://en.wikipedia.org/wiki/Cython) Cython is a compiled language
which will produce extension modules that can be imported into regular
Python or CPython code. Once I have this CPython code, will it work in
Grinder or does Grinder specifically need Jython?

The question is whether Grinder can support C-Python?
