Procedure

1. Go to Logs and Reports → Log Settings.
2. Under Log Options, set the following parameters:
   1. Select the violation types to log.

      Note Enable violation logs for additional information about traffic activity or for troubleshooting. Disabling violation logs may improve performance.

   2. Select Enable traffic log to enable traffic statistics logging.

      Note To capture log data, also enable traffic logging from the policy rule. For details, see Adding Policy Rules. Turning on the traffic log consumes much more storage than the violation logs alone. Use a syslog server to offload the logs from the box to keep logs for a longer period

3. Under Log Management, set the following limits as needed:

   Option	Description
   Limit storage usage for violation log(GB)	Default: 2GB
   Limit storage usage for traffic log(GB)	Default: 7GB

4. If needed, change the purge value for the number of days to retain logs before deleting logs.

   Note Setting the value to less than 62 days may prevent monthly report generation. Setting the value to more than 62 days could cause the accumulated data size to affect performance. Older logs are automatically removed when the logs exceed the size limitation.

5. Under Syslog Server, select the Enable syslog and forward all logs to syslog server check box, if needed.
   1. Specify the IP address and port number to forward syslogs.
6. Click Apply.
