Disagree. We need a log rotation support.
As I can see, available options could be:
* rotating conditions
- by date (rotate every hour, day (default), week, month, year)
- by file size (rotate if file size more than ... Mb)
- by count log lines (rotate if log contains more than ... log
lines)
- combination of previous conditions (for example, rotate
every day or rotate if file size more than 100 Mb)
* file names after rotation
- by numbers (my.log, my.log.0, my.log.1, ...)
- by ISO date and time (my-2013-10-16-00-00-00.log)
* ability to use system log rotation utility
I really like that Boost::Log also provides an option to
replace old log files (instead of creating new ones) when disk
capacity reaches a certain threshold. It might also be worth
providing an option to simply limit the max log file count to
N, which then replaces oldest first. In some unexpected
situations I've seen the disk fill from a badly behaved
program, and these are a nice safeguard.
+1
* delete old files when:
- you have more than N files
- size of all log files more than ... Mb
* support compress rotated files (for examle, in zip or gzip
format)
