Log Subscriptions
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 m for megabytes and k for
kilobytes. For example, enter 10m if you want AsyncOS to roll over the log file when it reaches 10
megabytes.
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 d, h, and m as suffixes.
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
logconfig 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).
If you are using the CLI, you can use a dash (-) to specify a range of days, an asterisk (*) to specify
every day of the week, or a comma (,) to separate multiple days and times.
