As explained in the EMA Developers guide (6.1 - EMA Logger Usage), EMA uses the SLF4J logging API. Thanks to SLF4J, you can have the underlying logging back-end that you want. For example: The Java standard logger utility package (java.util.logging), log4j, or other logger adapters which implement the SLF4J logging interface.
In your case, as you probably did not set any adapter, SLF4J prints messages on the console. A quick and easy solution for you would be to use the JDK build-in logging utility by setting it on the java command line. As an example: If you use the example100__MarketPrice__Streaming.bat file to run your application, you could add “-Djava.util.logging.config.file=.\logging.properties” as a new parameter of the java command (last line of the .bat file) and provide “logging.properties” configuration file (see below) along with your application.
Here is an example of the java command with all parameters:
%JAVA_BIN% -Djava.util.logging.config.file=.\logging.properties -cp %CLASSPATH% com.thomsonreuters.ema.examples.training.consumer.series100.example100__MarketPrice__Streaming.Consumer
Here is an example of logging.properties file with console and file logs deactivated:

Hi @Umer Nalla,
We are developing our own application based on the example given in program
consumer = EmaFactory.createOmmConsumer(config.host(host+":"+port).username(userId));
We are doing our custom logging, but when the above statement in italics and bold is encountered, EMA API level logging is being logged over the console as below

Text: Received ChannelUp event on channel Channel_1

Component Version ads3.0.6.L1.linux.tis.rrg 64-bit
We want to restrict this EMA API level logging, that is we don't want to get this logging appear.
Request you to please help us here
As mentioned in the EMA Java Dev Guide, it uses SLF4J logging API and therefore you could change the Logger level via a logging.properties file to WARNING or ERROR to avoid seeing INFO level outputs - or redirect the output a file instead.
There is a sample logging.properties file in the Ema\Src\main\resource folder which you could copy, amend and use for your application.
