Red Hat Training
A Red Hat training course is available for Red Hat JBoss Data Virtualization
9.2. Command Logging API
If you want to build a custom appender for command logging that will have access to
java.util.logging.LogRecord
s to the "COMMAND_LOG" context, the handler will receive a message that is an instance of LogRecord
. This object will contain a parameter of type org.teiid.logging.CommandLogMessage
. The relevant Red Hat JBoss Data Virtualization classes are defined in the teiid-api-[versionNumber].jar
. The CommandLogMessage includes information about VDB, session, command SQL, etc. CommandLogMessages are logged at the DEBUG level. An example follows.
package org.something; import java.util.logging.Handler; import java.util.logging.LogRecord; public class CommandHandler extends Handler { @Override public void publish(LogRecord record) { CommandLogMessage msg = (CommandLogMessage)record.getParameters()[0]; //log to a database, trigger an email, etc. } @Override public void flush() { } @Override public void close() throws SecurityException { } }
