• Through the log files that are stored in the <PRODUCT_HOME>/repository/logs folder. This folder contains current logs in a log file with a date stamp. Older logs are archived in the wso2carbon.log file.
• Through the command prompt/shell terminal that opens when you run the "wso2server.bat"/"wso2server.sh" files to start the Carbon server.   
• Through the advanced monitoring capabilities in WSO2 BAM. 
• Through the management console of your product. This option is only available if the Logging Management feature is installed in your product.

Limiting the size of the wso2carbon.log file

You can limit the size of the <PRODUCT_HOME>/repository/logs/wso2carbon.log file to archive and get backups of the logs stored in it periodically as preferred. Follow the steps below to add the configurations to limit the size of the <PRODUCT_HOME>/repository/logs/wso2carbon.log file.

1. Change the log4j.appender.CARBON_LOGFILE=org.wso2.carbon.logging.appenders.CarbonDailyRollingFileAppender appender in the <PRODUCT_HOME>/repository/conf/log4j.properties file as follows.
   log4j.appender.CARBON_LOGFILE=org.apache.log4j.RollingFileAppender

2. Add following two properties under the RollingFileAppender.

   log4j.appender.CARBON_LOGFILE.MaxFileSize=10MB 
log4j.appender.CARBON_LOGFILE.MaxBackupIndex=20

   Info
   If the size of the log file is exceeding the value defined in the MaxFileSize property, then the content is copied to a backup file and the logs are continued to be added to a new empty log file. The MaxBackupIndex property makes the Log4j keep a given maximum number of backup files for the logs.
