Payara – How To Set Loglevels

Running payara server for test or production requires sometimes more details about the running services. In this case you can increase the log level for a java-package or a single java class.

First you need to log into the server and run the asadmin command:

$ cd ~/appserver/glassfish/bin
$ asadmin

Next you can list the current loggers:

asadmin> list-log-levels
Enter admin password for user "admin"> 
ShoalLogger    
com.hazelcast    
com.sun.enterprise.server.logging.GFFileHandler    
com.sun.enterprise.server.logging.SyslogHandler    
.......

To set a specific log level run

set-log-levels com.foo.MyService=FINEST

And don’t forget to disable the log level after debugging 😉
