I am trying to create 4 different logs to write to (using Tomcat). Here is the code (There is some odd stuff because I’m experimenting with it):

log4j = {

    appenders {
        rollingFile  name:'infoLog', file:'/logs/info.log', threshold: org.apache.log4j.Level.INFO
        rollingFile  name:'warnLog', file:'/logs/warn.log', threshold: org.apache.log4j.Level.WARN
        rollingFile  name:'errorLog', file:'/logs/error.log', threshold: org.apache.log4j.Level.ERROR
        rollingFile name:'debugLog', file:'/logs/debug.log', threshold: org.apache.log4j.Level.DEBUG
    }
    root {
        info 'infoLog', 'errorLog', 'warnLog', 'debugLog'
        error 'errorLog'
        warn 'warnLog'
        debug 'debugLog'        
    }

    info 'grails.app'
    error  'org.codehaus.groovy.grails.web.servlet',  //  controllers
           'org.codehaus.groovy.grails.web.pages', //  GSP
           'org.codehaus.groovy.grails.web.sitemesh', //  layouts
           'org.codehaus.groovy.grails.web.mapping.filter', // URL mapping
           'org.codehaus.groovy.grails.web.mapping', // URL mapping
           'org.codehaus.groovy.grails.commons', // core / classloading
           'org.codehaus.groovy.grails.plugins', // plugins
           'org.codehaus.groovy.grails.orm.hibernate', // hibernate integration
           'org.springframework',
           'org.hibernate',
           'net.sf.ehcache.hibernate'

    warn   'org.mortbay.log'
    debug 'grails.app'
}

When I deploy and run the app, I get this in catalina.out:

log4j:ERROR setFile(null,true) call failed.
java.io.FileNotFoundException: /logs/info.log (No such file or
directory) at java.io.FileOutputStream.openAppend(Native Method) at
java.io.FileOutputStream.(FileOutputStream.java:177) at
java.io.FileOutputStream.(FileOutputStream.java:102)…

(I get that same message for each log I’m trying to create). Am I missing something?

Thanks

    That particular error message probably means either that the /logs directory does not exist or that it is not writeable by the user ID that your Grails app is running under.

    But more generally, your root logger definition is wrong, you just need one log level (the level you want to use by default for loggers where you don’t specify a more precise rule) attached to all the appenders, e.g.

    root {
    error 'infoLog', 'errorLog', 'warnLog', 'debugLog'
}

    The thresholds of the various appenders will ensure that each gets the right messages: with this configuration debugLog will receive all messages (debug, info, warn and error); infoLog will receive info, warn and error; warnLog will receive warn and error; and errorLog will receive only error messages.
