LogRecord instances are created every time something is logged. They contain all the
information pertinent to the event being logged. The main information passed in is in msg and
args, which are combined using msg % args to create the message field of the record. The
record also includes information such as when the record was created, the source line where
the logging call was made, and any exception information to be logged.
LogRecord has no methods; it's just a repository for information about the logging event.
The only reason it's a class rather than a dictionary is to facilitate extension.
-
| class LogRecord( |
name, lvl, pathname, lineno, msg, args, exc_info) |
- Returns an instance of LogRecord initialized with interesting
information. The name is the logger name; lvl is the numeric level; pathname
is the absolute pathname of the source file in which the logging call was made; lineno
is the line number in that file where the logging call is found; msg is the
user-supplied message (a format string); args is the tuple which, together with
msg, makes up the user message; and exc_info is the exception tuple
obtained by calling sys.exc_info() (or None,
if no exception information is available).
