storage or to reduce the risk of losing log information if you run out of disk space on your IPSO
appliance. You might also choose to send all of the logs from multiple computers to one
centralized log server, possibly one that is configured for high availability. You can select the
severity levels of messages to send to remote devices.
To configure your system to send syslog messages to a remote system, use the following
procedure.
To send syslog messages to a remote system
1. Click System Logging under Configuration > System Configuration in the tree view.
2. Enter the IP address of the host machine to which you want to send syslog messages.
3. Click Apply.
4. Click the Added Security Level drop down window and select at least one severity level.
Specifying a particular severity level means that all messages at least that severe are sent to
the associated remote host. You can choose Emergency, Alert, Critical, Error, Warning,
Notice, Info, Debug, or All. If you specify more than one severity level, all messages that are
least as severe as the lowest severity level you select are sent to the remote host.
Note
You must select at least one severity level for this option to function. The system will not
send syslog messages to the remote host if you do not configure at least one severity
level.
5. Click Apply.
The name of each severity level appears in Log at or above severity field.
6. To disable any of the severity levels, click No next to the name of the severity level you want
to delete.
7. Click Apply.
8. Click Save to make your changes permanent.
Configuring Logging on Flash-Based Systems
On flash-based (diskless) systems, log files do not persist across system reboots unless they are
stored on an appropriate device.
You can store log files on either or both of the following:
Remote log servers (primary and secondary)
If you decide to use remote systems, you must configure them to store the log files.
PC card flash memory in the flash-based system
If you decide to use PC card flash memory, you must install and configure it before you set
up the system
logging. (For information about installing a
flash memory
card, see
“To install
and configure PC card flash memory” on page 156
