The following variables may be used in the message and in msgFormat:

  • {timestamp} Date and time of creation
  • {typeNr} Type of the message in numeric format (0-3)
  • {type} Type of the message in string format (DEBUG, WARNING, CRITICAL, FATAL)
  • {thread} ID number of the thread

  • {function} Function where the message was generated
  • {line} Line number where the message was generated
