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, dispatches each message to any
or all of the following destinations:
-- Workstation display
-- Local log file
-- Designated printer
-- One or more remote hosts
