Syslog Message Format
Syslog messages begin with a percent sign (%) and are structured as follows:
%ASA Level Message_number: Message_text
Field descriptions are as follows:
Severity Levels
Table 1-1 lists the syslog message severity levels. You can assign custom colors to each of the severity
levels to make it easier to distinguish them in the ASDM log viewers. To configure syslog message color
settings, either choose the Tools > Preferences > Syslog tab or, in the log viewer itself, click Color
Settings on the toolbar.
Note The ASA and ASASM do not generate syslog messages with a severity level of zero (emergencies). This
level is provided in the logging command for compatibility with the UNIX syslog feature but is not used
by the ASA.
ASA The syslog message facility code for messages that are generated by the ASA and
ASASM. This value is always ASA.
Level 1 through 7. The level reflects the severity of the condition described by the syslog
message—the lower the number, the more severe the condition. See Table 1-1 for
more information.
Message_number A unique six-digit number that identifies the syslog message.
Message_text A text string that describes the condition. This portion of the syslog message
sometimes includes IP addresses, port numbers, or usernames.
