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.
