Grails(24)Grails Deploying and Logging with Tomcat

Grails(24)Grails Deploying and Logging with Tomcat

1. Tomcat Configuration
DB configuration in conf/conext.xml
    <Resource name="jdbc/lmm" auth="Container" type="javax.sql.DataSource"
               maxIdle="30" maxWait="-1" maxActive="100"
               factory="org.apache.tomcat.jdbc.pool.DataSourceFactory"
               testOnBorrow="true"
               validationQuery="select 1"
               logAbandoned="true"
               username="root"
               password=“password"
               driverClassname="com.mysql.jdbc.Driver"
               url="jdbc:mysql://localhost:3306/sillycat?autoReconnect=true&amp;useServerPrepStmts=false&amp;rewriteBatchedStatements=true"/>

Change the bin/catalina.sh to fix the out of memory issue
export JAVA_OPTS="-Xms1024m -Xmx2046m -XX:NewSize=256m -XX:MaxNewSize=356m -XX:PermSize=256m -XX:MaxPermSize=356m -Dbuild.env=lmm.local"

2. Grails Logging
grails logging is controller by BuildConfig.groovy or some other groovy files. The content part should be as follow>

import org.apache.log4j.PatternLayout
import org.apache.log4j.Level
import org.apache.log4j.DailyRollingFileAppender

log4j = {
        def logLayoutPattern = new PatternLayout("%d [%t] %-5p %c %x - %m%n")

        appenders {
                rollingFile name: "stacktrace", file: "/var/log/sillycat/stacktrace.log", maxBackupIndex: 5, threshold: Level.ERROR, layout:logLayoutPattern
                console name: "stdout", threshold: Level.DEBUG, layout: logLayoutPattern
                rollingFile name: "appFile", file: "/var/log/sillycat/appDebug.log", maxBackupIndex: 5, threshold: Level.ERROR, layout: logLayoutPattern
                appender(new ScrubbingAppender(
                                name: "scrub",
                                threshold: Level.ERROR,
                                layout: logLayoutPattern,
                                regex: "^(com.sillycat).*\$"
                ))
                appender new DailyRollingFileAppender(
                                name: "pushnotifications",
                                threshold: Level.ERROR,
                                layout: logLayoutPattern,
                                datePattern: "'.'yyyy-MM-dd-a",
                                file: "/var/log/sillycat/pushnotifications.log"
                )

        }

        error appFile: [
                        'com.sillycat',
                        'grails.app.test.integration.com.sillycat.lmm.security',
                        'grails.app.service.com.sillycat.lmm.geoFences',
                        'grails.app.service.com.sillycat.lmm.events',
                        'grails.app.controller.com.sillycat',
                        'grails.app.bootstrap.com.sillycat',
                        ‘grails.app.jobs'
                        ],

              stdout: [
                          'com.sillycat',
                          'com.sillycat.lmm.geoFences',
                          'com.sillycat.lmm.events',
                          'grails.app.service.com.sillycat.lmm.geoFences',
                          'grails.app.test.integration.com.sillycat.lmm.security',
                          'grails.app.service.com.sillycat.lmm.events',
                          'grails.app.controller.com.sillycat',
                          'grails.app.bootstrap.com.sillycat',
                          'grails.app.jobs.com.sillycat'],

            pushnotifications:        [
                              'com.sillycat.lmm.pushNotifications',
                              'grails.app.service.com.sillycat.lmm.events.StoreAnnouncementEventService',
                              'grails.app.service.com.sillycat.lmm.campaigns.StoreAnnouncementCampaignService',
                              'grails.app.service.com.sillycat.lmm.campaigns.BroadcastCampaignService',
                              'grails.app.service.com.sillycat.lmm.events.PushCallbackEventService',
                              'com.sillycat.lmm.campaigns.BroadcastCampaignService',
                              'com.sillycat.lmm.events.StoreAnnouncementEventService',
                              'grails.app.service.grails.plugin.executor']

        root {
                info 'scrub'
        }
}

Pay attention to this line
rollingFile name: "stacktrace", file: "/var/log/sillycat/stacktrace.log", maxBackupIndex: 5, threshold: Level.ERROR, layout:logLayoutPattern

If I did not configure that it will automatically create a log file under tomcat command runtime directory or our grails command runtime directory.

3. Tomcat Logging Configuration
Logging file conf/logging.properties

I turn them off
1catalina.org.apache.juli.FileHandler.level = OFF

There are 7 level of the log
SERVRE(highest) > WARNING>INFO>CONFIG>FINE>FINER>FINEST

For example:
1catalina.org.apache.juli.FileHandler.level = OFF
1catalina.org.apache.juli.FileHandler.level = FINE
1catalina.org.apache.juli.FileHandler.level = ALL
