12:01:29.796 [NioProcessor-2] DEBUG o.a.m.core.filterchain.IoFilterEvent - Firing a SESSION_CREATED event for session 1 12:01:29.797 [NioProcessor-2] DEBUG o.a.m.core.filterchain.IoFilterEvent - Event SESSION_CREATED has been fired for session 1

how to disable these logs.

Answer 1

You need to get the Mina logger instance and then disable logging on it. The following should work

    Logger minaLogger = (Logger) LoggerFactory.getLogger("org.apache.mina");
    if(minaLogger!=null)
    {
        minaLogger.setLevel(Level.OFF);
    }

Answer 2

I recently had to do this with mina that was integrated with a Spring boot application. Firstly you can use the actuator endpoint to find the logger in question:

GET /actuator/loggers

Examine the output json for the logger in question then adjust the level in the Spring boot application yaml:

logging:
  level:
    org.apache.sshd.server.session.ServerSessionImpl: error

In a Docker environment this silenced a 'connection reset be peer' WARN log line that was repeatedly generated by a container port scanner.

Answer 3

With log4j (and slf4j over log4j): you can disable any logs for any specified java package.

You can update your logging configuration inside your log4j.properties configuration file with :

# log4j: how to control logging at package level
log4j.logger.org.apache.mina=LOG_LEVEL 
# where LOG_LEVEL will be the level you need: OFF, INFO, DEBUG, ERROR

Maybe these question is a duplicate of : How do you Change a Package's Log Level using Log4j?
