Jboss7.x + Common Log file location + cluster mode

[sabbirali]

Dear all,

I have deploy ear application in cluster mode with three instance. its working fine and log is created in each instance of log folder.

I want to set all logs path in one directory. Please suggest me how to do it.

I need all instance log file in one location with instance name or instance id appended in log file name.

Please help me.

hi,

i have the same needs and looking for server node name variable to insert in the log4j path appender, but still not found the way.

can anyone advice us?

thanks in advance

You can use this for the FILE handler:

   <file path="/mylog/server-${jboss.node.name}.log"/>

You need to set the jboss.node.name if you have all instances at the same physical machine.

I prefer to link the log directory to another location or vice-versa, in that case you did not have the need to change the configuration.

But you should not point to a mounted filesystem as this might cause issues.

If you are using the  $JBOSS_HOME/bin/domain.sh or any service script [script in /etc/rc.d/init.d]  to start the server, there you can supply the ${jboss.server.log.dir} at startup:

-Djboss.server.log.dir=/where/ever/you/want

This gives you the advantage, that, if you are using log4j to configure your application's logging and use the same ${jboss.server.log.dir} env. in the rolling appender path, all your logs are in the same folder.

Note: If your jboss is running as some $JBOSS_USER, that user must have RW permissions on /where/ever/you/want directory.

hi Dear Wolf-Dieter Fink very appreciated your post....

It was very usefull.

One more thing:

But you should not point to a mounted filesystem as this might cause issues.

i am quite worried about this: i'm going to use a LUN/SAN to mount to /project/applicationslogs, may i have issues?

thank you again.

"mounted" might be a bit unclear, sorry.

What I meant was if you use slower filesystems like NFS, Samba ... in that case the IO might to slow and the applications slow down if there is a lot of logging IO

hi,

the scenario: 2 machines, 1 domain, 4 nodes (2xmachines): 1 LUN(SAN) attached via fiber channel cables to the machines and mounted on /project/applicationLogs/ i hope this kind of scenario will not encounter any issues....

What I meant was if you use slower filesystems like NFS, Samba ... in that case the IO might to slow and the applications slow down if there is a lot of logging IO

if you meant samba or nfs, so you was talking about IO performance... ok i am quite relieved.

thank you again....

exactly

I would still prefer using some distributed logging software, specifically designed for the task, or setup scheduled job to do that regularly.
