The documented settings don't work as described. When I increase the file size, it still remains at 10MB to roll. Also, when I reduce the days to keep files, they don't get removed and many days are kept.
Update the Log File History and Size
and then add the following hidden properties:
By default, the log files rotate when they reach 10 MB. The rotated log files are retained for seven days, unless you update the value of this setting.
In this example, the log files are retained for 14 days.
Define the size of the total log archive. When the archive size exceeds the threshold, backups are deleted. The supported units are: byte; kilobyte; megabyte; gigabyte; terabyte
In this example, when the total log archive size exceeds 1GB the backups get deleted.
