Configuring and Viewing Logs
d. In the Recycle field, specify the size of the syslog file (in bytes) that can be recycled when it is stored
on a disk. The default value of the file size is 10000000.
Whenever the current log file size surpasses the recycle size, the log file is rotated. (The default
recycle size for the log file is 10,000,000 bytes.) The log file cycles through at most five rotations,
and each rotation is saved as log_file_name.[1-5] under the same directory as the original log.
The rotated log file is configured in the File Name field (or by using the logging disk filename
command).
Step 7 Enable syslog files to be sent to a host:
a. In the Host Settings section, check the Enable check box. You can configure up to four hosts to
which syslog messages can be sent. For more information, see the “Multiple Hosts for System
Logging” section on page 1-53.
b. In the Hostname field, enter a hostname or IP address of the remote syslog host. Specify up to three
more remote syslog hosts in the Hostname fields 2 through 4. You must specify at least one hostname
if you have enabled system logging to a host.
c. From the Priority drop-down list, choose the severity level of the message that should be sent to the
specified remote syslog host. The default priority code is “warning” (level 4). Each syslog host is
capable of receiving a different level of event messages.
(See Table 1-16 for a list of priority levels.)
d. In the Port field, specify the destination port on the remote host to which the WAAS device should
send the message. The default port number is 514.
e. In the Rate Limit field, specify the number of messages per second that are allowed to be sent to the
remote syslog host. To limit bandwidth and other resource consumption, messages to the remote
syslog host can be rate limited. If this limit is exceeded, the specified remote syslog host drops the
messages. There is no default rate limit, and by default all syslog messages are sent to all of the
configured syslog hosts.
Step 8 Click Submit.
To configure system logging from the CLI, you can use the logging global configuration command.

a corresponding event.
