Wildfly 9 how to use rotate-on-boot?

[hchenkwi]

Hi,

I'm using Wildfly 9.0.2 final version.  I'm trying to set up logging using rotate-on-boot property, so everytime the Wildfly is shutdown and brought up, the log file rotate.

What I want is:

1. the log file rotate everyday 

2. the log file rotate whenever Wildfly get restarted.

But it doesn't seem that the server.log file get rotated when I shutdown and bring up Wildfly.  Can anyone tell me how to make it work?

The following is what I added:

        <custom-handler name="FILE" class="org.jboss.logmanager.handlers.PeriodicSizeRotatingFileHandler" module="org.jboss.logmanager">

            <level name="DEBUG"/>

            <formatter>

                    <named-formatter name="PATTERN"/>

            </formatter>

            <properties>

                <property name="autoFlush" value="true"/>

                <property name="append" value="true"/>

                <property name="suffix" value=".yyyy-MM-dd"/>

                <property name="fileName" value="${jboss.server.log.dir}/server.log"/>

                <property name="rotateOnBoot" value="true"/>

                <property name="maxBackupIndex" value="10"/>

                <property name="rotateSize" value="1099511627776"/>

            </properties>

        </custom-handler>

            <root-logger>

                <level name="DEBUG"/>

                <handlers>

                    <handler name="CONSOLE"/>

                    <handler name="FILE"/>

                </handlers>

            </root-logger>

Thanks, Helen

Hello Helen,

One option that i can think of will be to pass the server.log file name dynamically based on the timestamp as following:

1. Edit the standalone.xml (Or your profile file)  file and then edit it as following:  <file relative-to="jboss.server.log.dir" path="${server.log.dynamic.name}"/>

<periodic-rotating-file-handler name="FILE" autoflush="true">
    <formatter>
        <named-formatter name="PATTERN"/>
    </formatter>
    <!-- <file relative-to="jboss.server.log.dir" path="server.log"/> -->
    <file relative-to="jboss.server.log.dir" path="${server.log.dynamic.name}"/>    <!-- NOTICE !!! -->
    <suffix value=".yyyy-MM-dd"/>
    <append value="true"/>
</periodic-rotating-file-handler>

2. Now start the WildFly by passing the dynamic file name:

./standalone.sh -c standalone.xml -Dserver.log.dynamic.name=server_`date +%Y%m%d-%H%M`.log

In your case you can try doing the same thing with your "custom-handler"   As following:

 <property name="fileName" value="${jboss.server.log.dir}/${server.log.dynamic.name}"/>

Hi Jay,

Your solution is actually specifying the log file name at startup script.

Then what does  the rotate-on-boot flag mean? I thought it will rotate the log file automatically. Maybe my understanding for this flag is wrong.

Thanks a lot for your help,

Helen
