Syslog Daemon

The Fabric OS can be configured to use a UNIX style syslog daemon (syslogd)
process to read system events and forward system messages to users and/or write
the events to log files on a remote UNIX host system. See
on page 173.

syslogd Overview

The Fabric OS in the Core Switch 2/64 and SAN Switch 2/32 maintains an
internal log of all error messages. The internal log buffers are limited in capacity;
when the internal buffers are full, new messages overwrite old messages.
The Core Switch 2/64 can be configured to send error log messages to a UNIX
host system that supports syslogd. This host system can be configured to receive
error/event messages from the switch and store them in files on the computer hard
drive. This enables the storage of switch error log messages on a host system and
overcomes the size limitations of the internal log buffers on the Core Switch 2/64
switch.
The syslogd is a process that runs on UNIX or LINUX systems that reads and logs
messages to the system console, log files, other machines, and users as specified
by its configuration file. Refer to the manual pages and related documentation for
your particular UNIX host system for more information on the syslogd process
and its capabilities.
Note that the host system can be running UNIX, Linux or any other operating
system as long as it supports standard syslogd functionality. The Core Switch 2/64
or SAN Switch 2/32 itself does not assume any particular operating system to be
running on the host system. The only requirement is that the host system must
support standard syslogd to receive error log messages from the Core Switch 2/64
or SAN Switch 2/32.

syslog Error Message Format

Below is an example of an error/event message received by the remote syslogd
host from the Core Switch 2/64 switch.
Jun 4 18:53:59 sqab186 kernel: 0x299 (fabos): Switch: 0, Info
HAMKERNEL-IP_UP, 4, (session=16) Heartbeat up from Standby CP
The first two items are the event's date and time (as known by the UNIX host
machine where syslogd is running) and the machine name that generated the
message (In this case it is the name of the Core Switch 2/64 switch). The Core
