Glassfish logging suddenly stops

问题:

We're running many instances of glassfish in a linux box and suddenly they stop logging (a blank server.log file is created and no logging data is appended to it).

it happens after something like a week of normal logging.

How can I fix it?

How can I diagnose the problem -there's something like a log of the logger internals :p-?

回答1:

Check the logging properties of your domain (domain-dir/config/logging.properties). If there is nothing logged at all the GFFileHandler logging level might be set to "OFF" (Glassfish-18205 bug).

Try to set it to a different level with CLI:

asadmin set-log-levels com.sun.enterprise.server.logging.GFFileHandler=ALL

This sometimes happens while playing with logging levels in glassfish.
