How to disable JMeter log information output to console (in java)

Question

I was developing a jmeter test plan from java code, and I've installed jmeter api from maven.

It runs successfully. However, it shows lots of needless information on the console.

Here is my environment:

• JavaSE 1.7
• JMeter 3.0
• Windows 7

And I'm forced to do that although I know it's the old version of java and jmeter.

I've tried to configure jmeter.properties, logkit.xml and log4j.conf file, but it remains the same.

The information showing on console looks like:

Can anyone help me?

If you want to suppress JMeter logging you can set the log level for JMeter to FATAL_ERROR by providing the relevant JMeter Properties

<configuration>
    <propertiesJMeter>
        <log_level.jmeter>FATAL_ERROR</log_level.jmeter>
        <log_level.jmeter.junit>FATAL_ERROR</log_level.jmeter.junit>
        <log_level.jorphan>FATAL_ERROR</log_level.jorphan>
    </propertiesJMeter>
</configuration>

In general you should not see any of JMeter log entries in the console so it seems you have configuration overrides somewhere so it would be better to revert the changes you made rather than applying my solution.
