|
|
Level 1 | Mirroring disk volume. Protects data by automatically backing up the |
| contents of one disk onto the second disk of a mirrored pair. Mirroring |
| protects data if one disks fails. Disk capacity is equal to a single hard disk |
| because the second hard disk is used to automatically back up the first. |
| Use Level 1 to protect important personal or corporate data. |
Level 5 | RAID 5 disk group. Three or more hard disks can be teamed up to form a |
| |
| among member disks as it is received. At the same time RAID uses an |
| amount of space roughly equivalent to a whole disk to store reference |
| numbers with the same elements. If one of the disks in the group is |
| damaged, you can shut down the computer and install a new disk, and |
| the FortiLog unit can restore the data on the new disk using the reference |
| information. |
| If you have a system with four disks but use only three in your RAID 5 |
| group, the fourth serves as a backup disk. If one of the three disks is |
| damaged the FortiLog unit automatically reverts to the fourth disk without |
| powering down. |
| The approximate capacity of a RAID 5 disk group is one hard disk worth |
| of space less than the total rated capacity of the group. |
Log settings
To configure the FortiLog unit to log locally or to send FortiLog log messages to a remote syslog server, go to System > Config > Log Settings. You can configure the log level and you can use config policy to record event log messages. See “Log policy” on page 45 for information about the types of logs and how to configure them.
Figure 15: Log settings
Log Locally | Select this option to save the log messages on its own hard disks. |
Level | Select the severity for which you want to record log messages locally. The |
| FortiLog unit logs all levels of severity down to, but not lower than, the |
| level you select. For example, if you want to record emergency, critical, |
| and error messages, select Error. “Log policy” on page 45 lists the log |
| message levels. |
Config Policy | Select Config policy for which activities you want the FortiLog unit to |
| record log messages. |
Log to Host | Select Log to Host to configure the FortiLog unit to send log messages to |
| a remote syslog server. |
IP | The IP address of the remote syslog server. |
Port | The port that the remote syslog server uses to receive log messages. The |
| default port is 514. |
