Sets the format of log lines handled by this
PatternLayout. By default, set to "%m%n".
Format characters are as follows:
- <b>%%</b> - a single percent sign
- <b>%%c</b> - the category
- <b>%%d</b> - the date\n
Date format: The date format character may be followed by a date format
specifier enclosed between braces. For example, %%d{%%H:%%M:%%S,%%l} or %%d{%%d %%m %%Y %%H:%%M:%%S,%%l}.
If no date format specifier is given then the following format is used:
"Wed Jan 02 02:03:55 1980". The date format specifier admits the same syntax
as the ANSI C function strftime, with 1 addition. The addition is the specifier
%%l for milliseconds, padded with zeros to make 3 digits.
- <b>%%m</b> - the message
- <b>%%n</b> - the platform specific line separator
- <b>%%p</b> - the priority
- <b>%%r</b> - milliseconds since this layout was created
- <b>%%R</b> - seconds since Jan 1, 1970
- <b>%%u</b> - clock ticks since process start
- <b>%%x</b> - the NDC
