Configure Log Storage Quotas and Expiration Periods
The firewall automatically deletes logs that
exceed the expiration period. When the firewall reaches the storage
quota for a log type, it automatically deletes older logs of that
type to create space even if you don’t set an expiration period.
If you want to manually delete logs, select
Device
Log Settings
and,
in the Manage Logs section, click the links to clear logs by type.
Select
Device
Setup
Management
and
edit the Logging and Reporting Settings.
Select
Log Storage
and enter a
Quota
(%)
for each log type. When you change a percentage
value, the dialog refreshes to display the corresponding absolute
value (Quota GB/MB column).
Enter the
Max Days
(expiration
period) for each log type (range is 1-2,000). The fields are blank
by default, which means the logs never expire.
The firewall synchronizes expiration periods across
high availability (HA) pairs. Because only the active HA peer generates
logs, the passive peer has no logs to delete unless failover occurs
and it starts generating logs.
