    gclogs to stdout out jboss 7.1.1

    Niels Vanderbeke Newbie

      Hi,

       

      I have somme jboss instances running with verbose gc jvm parameters but the gc logging does not end up in a log file.

      i used jvm parameters : -verbose:gc -XX:+PrintGCDetails -XX:+PrintGCTimeStamps

       

      Using lsof i can see stdout and stderr are piped to somme where, but it is not the processcontroller log file , not the host controller log file and not the jboss server log file.

       

      [tele1558(root):/root] lsof -p 26034 | grep -v ".jar"

      java 26034 Sjbscrt    0r FIFO 0,8      0t0 151761310 pipe

      java 26034 Sjbscrt    1w FIFO 0,8      0t0 151761311 pipe

       

      I can nog use -Xloggc:/dir/gclog.log because i want auto log rotation on file size .

      Ik now there are experimental jvm options to allow this rotation but they are not available in my jvm version and because they are experimental i can not trust they will be available in feature jvm versions.

       

      • -XX:+UseGCLogFileRotation
        must be used with -Xloggc:<filename>;
      • -XX:NumberOfGCLogFiles=<number of files>
        must be >=1, default is one;
      • -XX:GCLogFileSize=<number>M (or K)
        default will be set to 512K.

       

      Can somme one help me to configure correct redirection of gc logs to jboss server.log?

       

      Thanks.

          As you are using the domain mode I think the gc.log will go somewhere as the console might not valid.

          But I did not see an issue to use the gc.log static for each restart with a time stamp as it will not be very big

            I configured the jboss server to start with loggc option in host.xml

             

                <server name="jbscrtCatA1" group="jbscrtCat" auto-start="true">
                    <paths>
                        <path name="custom.jboss.server.log.dir" path="/sup/loc/sft/jbscrt/machineA/log/jbscrtCatA1"/>
                    </paths>
                    <system-properties>
                        <property name="tnLogDir" value="/sup/loc/sft/jbscrt/machineA/log/jbscrtCatA1" boot-time="false"/>
                    </system-properties>
                    <socket-bindings socket-binding-group="standard-sockets" port-offset="3"/>
                    <jvm name="default">
                        <jvm-options>
                            <option value="-XX:OnOutOfMemoryError=&quot;kill -3 %p  &quot; -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/sup/loc/sft/jbscrt/machineA/log/jbscrtCatA1/ -verbose:gc -XX:+PrintGCDetails -XX:+PrintGCTimeStamps -Xloggc:/sup/loc/sft/jbscrt/machineA/log/jbscrtCatA1/gclog.log"/>
                        </jvm-options>
                    </jvm>

             

                </server>

             

            But he does not create the gclog.log file
