How can you turn off logging on Selenium-Server?

[Rex]

Hi all,

I have an environment that is VMed (i.e. virtual machine) so the less
disk activity we have the better the performance.

I need to turn off disk activity as much as possible. I cannot figure
out a way to do that on the Selenium Server (java -jar selenium-
server.jar).

I would also like to know how to turn off the command history on the
Selenium Browser when you lunch a test.

I appreciate your help.

Hi,

Which Selenium-RC version are you using?

If it is selenium 1.0.1 and above then after launching a test it will open two browser sessions, one will be your AUT and another contains selenium commands.

I think he's asking how to run this in a 'silent' mode so that extra browser isn't opened.  I'd be curious to know how to do this as well. 

Anyone?

1. I do not believe that you can turn off the info messages. If you
are running on Linux, you could fake it with something like 'java -jar
selenium-server.jar ... &> /dev/null'; I do not know what the Windows
equivalent of /dev/null is.
2. I do not believe that those info messages go to the disk, unless
you explicitly ask for it, therefore turning this off will not improve
your VM performance.
3. Have a look at 'java -jar selenium-server.jar -help' to see what is
possible.

HTH.

Luke,

Here's how you do it.

You should find a default logging.properties (its a utils logger property file) under your jdk installation [jre/lib/logging.properties]

Copy that file to the directory where you have your selenium jar.

Edit that file and then change the console handler level to OFF as shown below.

java.util.logging.ConsoleHandler.level = OFF

That should take care of it.

Dont forget to pass the path of this file to your java -jar command via the VM arg 

For e.g, : java -jar -Djava.util.logging.config.file=my.properties selenium.jar

On a side note, in case you wanted debug information to be written to a separate file, you can pass the VM arg -D

java -jar -Dselenium.LOGGER=dummy.txt selenium.jar

Thanks & Regards

Any updates on this? I would also like to turn off the logging I get to the Console by Selenium Server Standalone when running in grid mode.

Thanks Krishnan,

Using the logging.properties file as you suggested definitely turns off console logging - thanks! :)

Interestingly I'm seeing the console logging turn on again when I specify the selenium log file... Turning on the log file using your approach above or by specifying it with the '-log' selenium command line argument seems to ignore the fact that we turned off console logging in the properties file. Pretty weird!

Any ideas?

Kind Regards,

Luke

Luke,

Can you please show the command that you are using and also share your logging properties file because I cant seem to recreate this.

Thanks & Regards

I'm desperately trying to turn off our Selenium Server logger. We're grabbing the jar via maven and starting the server programmatically with server.start(). I cannot figure out how to mute the server logging.

Thanks for any help,

You need to have logging.properties on classpath, for instance src/main/resources.

You can switch off, but nicer direct jul logging to log4j.
Now in log4j.xml you can filter on packages.

Same works for common logging too.

Thanks Krishnan It worked for me.

But now I want to use this same mechanism while executing from Eclipse.

Can you guide me where and how to configure this property in eclipse project.?

[Kishori Patil]

I tried adding below in Default VM Arguments in Eclipse at Windows>Preferences>InstalledJRE >Edit

-Djava.util.logging.config.file=C:/my.properties

Still it doesn't work.

Please guide

My earlier resolution worked. Thanks :)

I have similar task and after some headache, I had done this through:

java -jar -Dselenium.LOGGER.level=WARNING /opt/selenium/selenium-server-standalone.jar 


You can change the level to "OFF" if you wanted to turn off all logs. 

Just play around it...
