Chapter 17 Configuring Logging
Logging Setup
Step 4 Check the Send syslogs in EMBLEM format check box to enable EMBLEM format so that it is used
for all log destinations, except syslog servers.
Step 5 In the Buffer Size field, specify the size of the internal log buffer to which syslog messages are saved if
the logging buffer is enabled. When the buffer fills up, messages will be overwritten unless you save the
logs to an FTP server or to internal flash memory. The default buffer size is 4096 bytes. The range is
4096 to 1048576.
Step 6 To save the buffer content to the FTP server before it is overwritten, check the Save Buffer To FTP
Server check box. To allow overwriting of the buffer content, uncheck this check box.
Step 7 Click Configure FTP Settings to identify the FTP server and configure the FTP parameters used to save
the buffer content. For more information, see Configure FTP Settings, page 17-3.
Step 8 To save the buffer content to internal flash memory before it is overwritten, check the Save Buffer To
Flash check box.
Note This option is only available in routed or transparent single mode.
Step 9 Click Configure Flash Usage to specify the maximum space to be used in internal flash memory for
logging and the minimum free space to be preserved (in KB). Enabling this option creates a directory
called “syslog” on the device disk on which messages are stored. For more information, see Configure
Logging Flash Usage, page 17-4.
Note This option is only available in single, routed or transparent mode.
Step 10 In the Queue Size field, specify the queue size for system logs that are to be viewed in the security
appliance.
