Modify console output

I want to ask similar question.

In the Console I found a lot of verses messages like this:

...
08-02-2018 03:08:50 PM - [START]  - Start action : Statement - sb = new java.lang.StringBuilder()
08-02-2018 03:08:50 PM - [END]    - End action : Statement - sb = new java.lang.StringBuilder()
08-02-2018 03:08:50 PM - [START]  - Start action : Statement - failures = result.getFailures()
08-02-2018 03:08:50 PM - [END]    - End action : Statement - failures = result.getFailures()
08-02-2018 03:08:50 PM - [START]  - Start action : Statement - For (org.junit.runner.notification.Failure failure : failures)
08-02-2018 03:08:50 PM - [END]    - End action : Statement - For (org.junit.runner.notification.Failure failure : failures)
...

These verbose messages make it hard to find output emitted by println().

How can I make Katalon logging less verbose?
