Different Levels of Logging to Different Appenders or Files:<\/strong><\/h4>\n

\n

When a project is running, then lot of log messages (all type of log messages e.g. Error, Fatal, Warning, Info, Debug etc.) are logged into a single log file. Many times we try to find the error messages only, instead of debugging the complete application. In that case we manage more than one log files.<\/p>\n

\n

Two simple steps to define multiple log files according to log level priority:<\/strong><\/h5>\n

\n

1<\/strong>. In appender block<\/strong> of log4j block<\/strong> in Config.groovy<\/strong>, add the appenders according to the number of log files. Here I have created two different log files, first one is for debug level logs and second one is for error level logs.<\/p>\n

[groovy]
\n\/**
\n * In appenders block, generated log file name will be with file attribute,
\n * and log level will define with threshold.
\n **\/
\nappenders {
\n rollingFile name:’debugLog’, file:’debug.log’, threshold: org.apache.log4j.Level.DEBUG
\n rollingFile name:’errorLog’, file:’error.log’, threshold: org.apache.log4j.Level.ERROR
\n}
\n[\/groovy]<\/p>\n

2.<\/strong> declare all the appenders in root block<\/strong> of log4j block<\/strong> in Config.groovy<\/strong> file as:
\n[groovy]
\nroot {
\n info ‘debugLog’, ‘errorLog’
\n}
\n[\/groovy]<\/p>\n

\n

Thats it. \ud83d\ude42<\/p>\n

\n

Note:<\/strong> When we are using log level files, then log level file will contain all that log level messages of that priority level and priority level above that.<\/p>\n
