Cons

  • limited number of categories (e.g., when compared to log4j), which limits filtering capabilities
  • system-wide, requires administrator privileges to set up
  • not available on all OS-s (e.g., Windows)

Pros

  • application logging is plug-and-play, with well-known locations
  • single place to filter all messages
  • factors a lot of common functionality (such as writing to a file, sending logs remotely, rotating log files)
  • tools can be build (and actually exist) which can look at the logs of all applications at once
