Rollover By File Size
AsyncOS rolls over log files when they reach a maximum file size to prevent them
from using too much disk space. When defining a maximum file size for rollovers,
use the suffix
for megabytes and
for kilobytes. For example, enter
want AsyncOS to roll over the log file when it reaches 10 megabytes.
Rollover By Time
If you want to schedule rollovers to occur on a regular basis, you can select one
of the following time intervals:
None. AsyncOS only performs a rollover when the log file reaches the
maximum file size.
Custom Time Interval. AsyncOS performs a rollover after a specified
amount of time has passed since the previous rollover. To create a custom
time interval for scheduled rollovers, enter the number of days, hours, and
minutes between rollovers using
Daily Rollover. AsyncOS performs a rollover every day at a specified time.
If you choose a daily rollover, enter the time of day you want AsyncOS to
perform the rollover using the 24-hour format (HH:MM).
Only the GUI offers the Daily Rollover option. If you want to configure a
daily rollover using the
command in the CLI, choose the Weekly
Rollover option and use an asterisk (*) to specify that AsyncOS should
perform the rollover on every day of the week.
Weekly Rollover. AsyncOS performs a rollover on one or more days of the
week at a specified time. For example, you can set up AsyncOS to rollover
the log file every Wednesday and Friday at midnight. To configure a weekly
rollover, choose the days of the week to perform the rollover and the time of
day in the 24-hour format (HH:MM).
