Using Technician Interface Software

C-2

Syslogd is a UNIX daemon software component that receives and locally logs,

displays, prints, and/or forwards messages that originate from sources internal and

external to the workstation. For example, Syslogd on a UNIX workstation

concurrently handles messages received from applications running on the

workstation, as well as messages received from Bay Networks routers running in a

network accessible to the workstation.

Figure C-1 illustrates the following Syslog and Syslogd functionality:

Syslog running on each slot

• Polls the local events log buffer to retrieve new event messages.

• Selects from the local events log messages that meet the requirements of

entity ﬁlters you conﬁgure on the router.

• Maps into Syslog message format any messages retrieved from the local

events log.

• Inserts a priority code into each reformatted message.

• Time-sequences messages if you ﬁrst enabled the message sequencing

feature.

• Forwards messages to IP on the router, which in turn forwards messages to

remote hosts identiﬁed in the Syslog host table.

At a remote UNIX management workstation, Syslogd

• Receives Syslog messages from Bay Networks routers.

• Examines the priority code in each message.

• Uses the priority code to determine appropriate system handling for each

message.

• Based on the priority code in each message, Syslog dispatches each message

to any or all of the following destinations:

— Workstation display

— A local log ﬁle

— A designated printer

— One or more remote hosts
