Detailed Description
DailyRollingFileAppender extends FileAppender so that the underlying file is rolled over at a user chosen frequency.
The rolling schedule is specified by the DatePattern option. This pattern should follow the SimpleDateFormat conventions. In particular, you must escape literal text within a pair of single quotes. A formatted version of the date pattern is used as the suffix for the rolled file name.
For example, if the File option is set to /foo/bar.log and the DatePattern set to '.'yyyy-MM-dd, on 2001-02-16 at midnight, the logging file /foo/bar.log will be copied to /foo/bar.log.2001-02-16 and logging for 2001-02-17 will continue in /foo/bar.log until it rolls over the next day.
Is is possible to specify monthly, weekly, half-daily, daily, hourly, or minutely rollover schedules.
| DatePattern | Rollover schedule | Example |
|---|---|---|
'.'yyyy-MM | Rollover at the beginning of each month | At midnight of May 31st, 2002 |
| Rollover at the first day of each week. The first day of the week depends on the locale. | Assuming the first day of the week is Sunday, on Saturday midnight, June 9th 2002, the file /foo/bar.log will be copied to /foo/bar.log.2002-23. Logging for the 24th week of 2002 will be output to |
| Rollover at midnight each day. | At midnight, on March 8th, 2002, |
| Rollover at midnight and midday of each day. | At noon, on March 9th, 2002, |
| Rollover at the top of every hour. | At approximately 11:00.000 o'clock on March 9th, 2002, |
| Rollover at the beginning of every minute. | At approximately 11:23,000, on March 9th, 2001, |
Do not use the colon ":" character in anywhere in the DatePattern option. The text before the colon is interpeted as the protocol specificaion of a URL which is probably not what you want.
Constructor & Destructor Documentation
◆ DailyRollingFileAppender() [1/2]
| log4cxx::DailyRollingFileAppender::DailyRollingFileAppender | ( | ) |
The default constructor simply calls its parents constructor.
◆ DailyRollingFileAppender() [2/2]
| log4cxx::DailyRollingFileAppender::DailyRollingFileAppender | ( | const LayoutPtr & | layout, |
| const LogString & | filename, | ||
| const LogString & | datePattern | ||
| ) |
Instantiate a DailyRollingFileAppender and open the file designated by filename.
The opened filename will become the ouput destination for this appender.
Member Function Documentation
◆ activateOptions()
|
virtual |
Prepares DailyRollingFileAppender for use.
Reimplemented from log4cxx::WriterAppender.
◆ getDatePattern()
| LogString log4cxx::DailyRollingFileAppender::getDatePattern | ( | ) | const |
Returns the value of the DatePattern option.
◆ setDatePattern()
| void log4cxx::DailyRollingFileAppender::setDatePattern | ( | const LogString & | pattern | ) |
The DatePattern takes a string in the same format as expected by SimpleDateFormat.
This options determines the rollover schedule.
◆ setOption()
|
virtual |
Set option to value.
The handling of each option depends on the OptionHandler instance. Some options may become active immediately whereas other may be activated only when activateOptions is called.
Reimplemented from log4cxx::AppenderSkeleton.
