Runtime errors in nGrinder 3.1

[viji1188]

Hi

I downloaded the new nGrinder controller version 3.1 WAR file and replaced it with the old WAR file

in tomcat webapps folder. I still use nGrinder agent version 3.0.3, Apache Tomcat Version 6.0.36

and JDK version 1.7.0_10.
I restarted the system and created the default script for a URL.
The performance test stops (with 1 Vuser and 1 iteration) with error message
"Stop By Error
Test is finished. but contains a lot of errors".

I don't see any error on validating the script and never received errors in nGrinder version 3.0 for the same URL.
Could anyone please tell me how can I see the complete details of the runtime errors.

Thanks
Vij

Please update agent as well

And show me the agent log in test report page

Hi Junoyoon

I upgraded the agent (ngrinder-core-3.1) and replaced the old agent folder. After restarting I ran a new test with default script.
I received following error:
"Stop By Error
SCRIPT_ERROR"
There was no error found while validating the script.
The test report page did not have any log and only had the following text:

"Logs
Getting log data form agent, please wait and refresh again; or there is no log because of agent error."


Thanks
Vij

[junoyoon]

I need followings.

- Could you try with duration not Run Count based?

- Please send me the logs appearing right down side of report panel.

 

 



- Please send the validation panel output in the script editor.

Hi
1. I ran performance test with following test configuration:
    a. Agent = 1
    b. Vuser per agent = 1
    c. Duration = 2mins

2. The test stopped before finishing the run duration. The test report did not have any log. Attached image:

3. I attached the validation panel output:

validationPanelOutput.txt

Thanks

[junoyoon]

You may not run agent with NGRINDER_AGENT_HOME env variable.

NGRINDER_HOME as well for controller.

Please check.

Hi JunHo

I reinstalled the controller 3.1, agent 3.1 and tomcat 6.0.36 files. Made sure there are no spaces in the file path. I followed the steps as per the following installation guide link and the steps you mentioned earlier,
http://www.cubrid.org/wiki_ngrinder/entry/installation-guide
The env var settings are the same and made sure that correct paths are provided (for CATALINA_HOME, JAVA_HOME, NGRINDER_AGENT_HOME, NGRINDER_HOME).
Restarted the system and ran a test on a default script for duration of 1minute. But, I am still not able to complete the test and I receive the same error message:
"Stop By Error
SCRIPT_ERROR"
There was no validation error and no log file was created in the test report.

Thanks

Dear Viji.

 

I'm suspecting your HW is running out of memory?

What's you memory size? 

after running Controller and Agent, What's the remained memory size?

nGrinder 3.1 agent needs at least 400m per agent to run the agent processes.

It's to reduce gabage collection.

One more stuff you should check is.. that
You correctly set up the JDK in the head of PATH.
nGrinder 3.1 uses "-server" mode to stabilize the agent performance.
If you mistakenly point JRE instead of JDK, the agent test processes will crash at the test execution.
please type "SET" in the command line and check the PATH entry there.
If you don't know how to interpret this, Please send it.

[viji1188]

Hi JunHo,

1. Even after running agent and controller, I have enough memory left.
2. The Java_Home is also pointing to JDK through right path:
JAVA_HOME=C:\Program Files\Java\jdk1.7.0_10

But I still receive error while running the performance test.

Thanks,
Vij

[junoyoon]

Dear vjjji 

 

What I told you is PATH not JAVA_HOME. 

Could you share followings for better reproduction?

After you run the test..

 

- ${NGRINDER_HOME}/logs/ngrinder.log

- ngrinder agent log in the screen. 

- type "set" in the command line and send the result.

- exact free memory size when you run controller and agent (not executing test)

 

Or... you can try the nGrinder 3.1.1 which is unveiled yet in public. You can download followings.

 

 

https://www.dropbox.com/s/al1ltlkxlzpjnin/ngrinder-controller-3.1.1.war

https://www.dropbox.com/s/8euw3ra6awm6abo/ngrinder-core-3.1.1-agent-package.zip

 

Please following the instruction.

- when you update the previous version, please delete previous versions first and locate these.

- Backup ${NGRINDER_HOME}/db and ${NGRINDER_HOME}/perftest folder (You can restore to previous version just replace them into previuos one.)

 

 

Regards.

Hi JunHo,

I updgraded nGrinder to version 3.1.1 as per the instructions and path (for setup file) you mentioned earlier. I still face the same problem.

        1. I have attached the NGRINDER_HOME (controller_home) log file.
ngrinder.log

        2. There is no agent log on the screen:
                "Getting log data form agent, please wait and refresh again; or there is no log because of agent error."
                But I still have attached the agent log file from NGRINDER_AGENT_HOME folder.
agent.log

        3. All the env variables (by typing "set" on cmd line) are as follows:

C:\Documents and Settings\VijethaK>set

I think I found the problem you have.

Your library path..  is...
2013-01-30 14:49:14,390 INFO  org.ngrinder.NGrinderStarter  :  java.library.path : C:\WINDOWS\system32;C:\WINDOWS\Sun\Java\bin;C:\WINDOWS\system32;C:\WINDOWS;C:\Perl\site\bin;C:\Perl\bin;C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\Program Files\Microsoft SQL Server\90\Tools\binn\;C:\Program Files\Microsoft SQL Server\100\Tools\Binn\;C:\Program Files\Microsoft SQL Server\100\DTS\Binn\;C:\Program Files\Microsoft Network Monitor 3\;C:\Program Files\Java\jdk1.7.0_10\;.;C:\ngrinder\agent\.\native_lib

Your path is....
Path=C:\Perl\site\bin;C:\Perl\bin;C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\Syst
em32\Wbem;C:\Program Files\Microsoft SQL Server\90\Tools\binn\;C:\Program Files\

TS\Binn\;C:\Program Files\Microsoft Network Monitor 3\;C:\Program Files\Java\jdk
1.7.0_10\

Look this.. you have C:\WINDOWS\Sun\Java\bin; at the beginning of your library path and C:\Program Files\Java\jdk1.7.0_10\ in the path.

You're thinking you run nGrinder with Java 1.7.0 .. but it doesn't seem like it. For example..
C:\Program Files\Java\jdk\1.7.0_10\ does not have any java.exe file.. C:\Program Files\Java\jdk\1.7.0_10\bin has java.exe..
Which means when you run the agent... it used the different java. (Maybe you're running JRE not JDK)

Please locate C:\Program Files\Java\jdk1.7.0_10\bin  in the head of PATH please. And run the agent again.

Hey JunHo, nGrinder works now. Thanks so much :)
