Configuring a Logging Profile in JBoss EAP

JBoss Enterprise Application Platform allows us to do more than simply deploy applications — we can also manage and maintain them during their lifecycle. Part of this is the ability to log what we need when we need it, which is where JBoss EAP logging profiles come in. Logging profiles allow us to write customized logging rules that we then attach to our applications as desired.

Create the Logging Profile

Access the JBoss EAP CLI:

cd /opt/jboss-eap/
sudo ./bin/jboss-cli.sh
connect

Create the appdebug logging profile:

Challenge

Create the File Handler

Create the file handler:

/subsystem=logging/logging-profile=appdebug/file-handler=appdebug-handler:add(file={path=>"debug.log", "relative-to"=>"jboss.server.log.dir"})

Set the log level for the handler:

/subsystem=logging/logging-profile=appdebug/file-handler=appdebug-handler:write-attribute(name="level", value="TRACE")

Challenge

Create a Logger Category

Add the logger category:

/subsystem=logging/logging-profile=appdebug/logger=app.debug:add(level=DEBUG)

Assign the handler to the category:

/subsystem=logging/logging-profile=appdebug/logger=org.hibernate:add-handler(name="appdebug-handler")

Challenge

Set Logs to Format as JSON

Ensure the logs will be formatted as JSON:

/subsystem=logging/logging-profile=appdebug/json-formatter=NAME:add(pretty-print=true, exception-output-type=formatted)
