Have Nodes log to main application log file
« on: July 06, 2011, 11:36:14 PM »

Hi there, I need the ability to log to a centralized log file that is configured by our application. Do you see any issues with the recommendation by apache within jppf?
http://logging.apache.org/log4j/1.2/faq.html#a3.3

Have you ever configured this, and know of any gotchas?

Thanks you in advance!

Hello,

JPPF already has a feature that allows servers and nodes to send logging statements as JMX notifications, with specific implementations for Log4j and JDK logging.
You can read how to set it up for node at this location: http://www.jppf.org/wiki/index.php?title=Node_management#Remote_logging
and for a server: http://www.jppf.org/wiki/index.php?title=Server_management#Remote_logging
What you can do is use the existing management APIs to get the list of nodes from the server, and subscribe to all JMX notifications from server and nodes from the same notification listener, and that will give you a centralized way to receive and process logging from the grid components.

I hope this helps.

Sincerely,
-Laurent

Hi Lauren,

Continuing the sam. We are not able to get centralized logging for node and driver. I got above information but not able to get log.
We have runner class which creates three agent which are implementing runnable, in these agent's run method we are creating job and putting multiple task in the same job which will run on node. We are getting log upto call to Node code, after that we are not getting logs.

Could you please help for this? Let me know if you require any information.

Thanks and regards,
Jaydatta
