log file of agents processing issue

Hi,

 

I am using JADE-LEAP 3.6.1 and logging some processing of three agents M Agent, O Agent and L Agent with the help of log4j API in a single log file agents.log.

I configured logger to generate backup files of log file every hour.

----------------------------------------------------

Log4j.properties file:-

 

log4j.rootLogger=DEBUG, stdout, agents

log4j.appender.stdout=org.apache.log4j.ConsoleAppender

log4j.appender.stdout.layout=org.apache.log4j.PatternLayout

log4j.appender.stdout.layout.ConversionPattern=%d %p [%C{1}][%M] --> %m\n

log4j.appender.agents=org.apache.log4j.DailyRollingFileAppender

log4j.appender.agents.layout=org.apache.log4j.PatternLayout

log4j.appender.agents.DatePattern=.yyyy-MM-dd-HH

log4j.appender.agents.layout.ConversionPattern=%d %p [%C{1}][%M] --> %m\n

log4j.appender.agents.File=${user.dir}/logs/agents.log

------------------------------------------------------

 

in all agents classes I am creating logger as

 

public class MAgent extends Agent{

 

            private Logger log =  org.apache.log4j.Logger.getLogger(MAgent.class.getName());

            @Override

            protected void setup() {

                        // -------------Some processing of MAgent ----------------//

 

                        log.debug("Agent " + this.getLocalName() + " is started.");

                        addBehaviour(new MAgentBehaviour(this));

            }

}

------------------------

In the same way we did logging in other agents also.

 

Problem :: agants.log file is overwritten every hour and no back up file is generated, meaning old log written in agants.log file is cleared and logging starts at the beginning of the file.

And all three agents show the ERROR message on console as “log4j:ERROR Failed to rename [location/logs/agents.log]\location/logs/agents.log.2009-10-28-14].”

 

Is their any specific way to log the agents processing?

Please suggest.

 

Thanks

Hi,

 

I’m not an expert of Log4j, but certainly there is nothing in JADE that can affect the way Log4j manages log files à I’m pretty sure that the problem depends on some wrong Log4j configuration.

 

Bye,
