Comment: Added java logging

...

Code Block
languagejava
static {
  LogFactory.setLogFactory(new Log4jLogFactory());
  org.apache.log4j.BasicConfigurator.configure();
  LogFactory.getLogFactory().getRootLogger().setLogLevel(LogLevel.ALL);
}


Enable Java Logging

To enable Java logging two steps are necessary:

Code

Code Block
languagejava
static {
    LogFactory.setLogFactory(new JavaLogFactory());
    // Optionally set log level on root logger:
  	LogFactory.getLogFactory().getRootLogger().setLogLevel(LogLevel.ALL);
}

Runtime Configuration

For SNMP4J-CLT 2.1 you need to configure the log handlers and format at runtime. In SNMP4J and any other SNMP4J-* API you can do this with code of course.

Add the parameter -Djava.util.logging.config.file=<file> to the Java command line:

Code Block
java -Djava.util.logging.config.file=java_logging.properties ...
Code Block
titlejava_logging.properties Sample Configuration
handlers = java.util.logging.ConsoleHandler
java.util.logging.ConsoleHandler.level = ALL
java.util.logging.ConsoleHandler.formatter = java.util.logging.SimpleFormatter
java.util.logging.SimpleFormatter.format=%1$tY-%1$tm-%1$td %1$tH:%1$tM:%1$tS %4$-6s %5$s%6$s%n
