Getting started with Log.apex

Log Information

Log.apex supports these log levels:

  • Error
  • Warn
  • Info
  • Debug
  • Trace

You can use any of these logging levels to print the log information.

logger.debug('Debug message');

Or you can pass in parameters:

logger.debug('Debug {0}', 'message');

Or you can check it for performance's sake.

if(logger.isDebugEnabled()) {
    logger.debug('Debug {0}', 'message');
}

However, with logging level Error, you need to provide the exception.

try {
    // ...
}
catch(Exception ex) {
    logger.error('some error', ex);
}
