Syslog is a message generating tool that can be implemented in any network device. The
intention of the tool is to send messages over the network indicating status, actions,
possible problems, etc. from the device.
Although the syslog protocol is widely spread and evolved to a de-facto standard, only
recently some first Internet drafts and informational Request For Comments (RFC)
became available to describe the existing protocol and some proposal for enhance-
ments.
TM
For the SpeedTouch 610, the syslog daemon conforms to the proposed standards as
much as possible.
Syslog messages consist of a message header called Priority and a message body
containing the message itself.
Via the Priority identification it is possible to determine the severity and facility of a
message, hence allows to diversify the messages according their importance. Each
severity and each facility can be identified by a numerical value. The sum of the numer-
ical values of the severity and the facility indicates (the numerical value of) the priority.
In the following all severities and facilities are listed with respective notation and numer-
ical values.
Following priority severities are possible for a syslog message generated by the
