SAN switch 2/32 Version 4.0.2b Release Notes
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 switch by
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 switch.
Error Message Format
An example of an error/event message received by the remote
syslogd
host
from the switch.
Jun 4 18:53:59 sqab186 kernel: 0x299 (fabos): Switch: 0,
Info HAMKERNEL-IP_UP, 4, (session=16) Heart-beatup from Standby
CP
Example Summary
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 switch). The word “kernel” is the name of
the
syslogd
facility used by the switch to send error log messages to the remote
host.
The rest of the message is similar to the error log message output from the
errShow
command line interface on the switch.
The fields that are specific to the switch error log message are:
■
ID of the task that generated the error (in the example this is 0x299)
■
Name of the task that generated the error (in the example this is (
fabos
))
■
Switch instance number (in the example this is Switch 0)
■
Message severity level in word (in the example this is Info)
The error message identifier consists of the module name (in the example this is
HAMKERNEL) and the message name (in the example this is IP_UP).
The numeric value of the message severity level is defined by the switch (in the
example this is 4). A descriptive text string is also provided (in the example this is
Heartbeat up from Standby CP).
