The standard Java logging defines the following log levels:
This is incompatible to RFC 5424, because it lacks a NOTICE level between INFO and WARNING. Java lacks some additional log levels (error, critical, alert and emergency) but NOTICE is the one which hurts me.
Is there any way to extend the list of possible log levels in order to add the missing NOTICE level? Or is it necessary to rewrite the whole logging?
This should work
class Level2 extends Level {
public static final Level2 NOTICE = new Level2("NOTICE", 850);
private Level2(String name, int level) {
super(name, level);
}
}
Thanks to Evgeniy. This is the complete example:
SyslogLevel
import java.util.logging.Level;
public class SyslogLevel extends Level
{
public static SyslogLevel EMERG = new SyslogLevel("EMERG", 1100);
public static SyslogLevel ALERT = new SyslogLevel("ALERT", 1000);
public static SyslogLevel ERR = new SyslogLevel("ERR", 950);
public static SyslogLevel WARNING = new SyslogLevel("WARNING", 900);
public static SyslogLevel NOTICE = new SyslogLevel("NOTICE", 850);
public static SyslogLevel INFO = new SyslogLevel("INFO", 800);
public static SyslogLevel DEBUG = new SyslogLevel("DEBUG", 300);
protected SyslogLevel (String name, int value, String resourceBundleName)
{
super (name, value, resourceBundleName);
}
protected SyslogLevel (String name, int value)
{
super (name, value);
}
}
logging
import java.util.logging.Logger;
import java.util.logging.Level;
import java.util.logging.FileHandler;
import java.util.logging.SimpleFormatter;
public class logging
{
public static void main(String[] args)
{
Logger logger = Logger.getLogger ("MyLog");
FileHandler fh;
try {
fh = new FileHandler ("logging.log", true);
logger.addHandler (fh);
logger.setLevel (Level.ALL);
fh.setFormatter (new SimpleFormatter());
logger.log (SyslogLevel.NOTICE, "Run!");
}
catch (java.io.IOException e) {
e.printStackTrace ();
}
}
}
