Log File Rollover Settings for Log Subscriptions
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
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.
Rollover By Time

intervals:
intervals:
•
None. AsyncOS only performs a rollover when the log file reaches the maximum file size.

since the previous rollover. To create a custom time interval for scheduled rollovers, enter the
number of days, hours, and minutes between rollovers using
