Logging severity levels in Drupal 7
Logging severity levels as defined in RFC 3164.
The WATCHDOG_* constant definitions correspond to the logging severity levels defined in RFC 3164, section 4.1.1. PHP supplies predefined LOG_* constants for use in the syslog() function, but their values on Windows builds do not correspond to RFC 3164. The associated PHP bug report was closed with the comment, "And it's also not a bug, as Windows just have less log levels," and "So the behavior you're seeing is perfectly normal."
