gclogs to stdout out jboss 7.1.1

[nielsvanderbeke]

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
