An example entry in a syslogd log file is:
Jul 18 12:48:00 sendmail[9558]: NOQUEUE: SYSERR(uucp):
/etc/mail/sendmail.cf: line 0: cannot open: No such file
or directory
The first two items are the event’s date/time (as known by the machine where
syslogd is running) and the machine name that issued the error. This would be
the local machine, if the message is generated by a task running on the same
machine as syslogd, or a remote machine, if the message was received on UDP
port 514. The first two items are always present, all other entries are message
specific.
NOTE: The log file may be located on a different machine and be remotely mounted. So a
local error is an error that occurred where syslogd is running, not on the machine where
the error log physically resides.
syslogd applications for NT and Win95 are available at no charge on several
FTP servers on the Internet
syslogd Support
Switch firmware maintains an internal log of all error messages. The log is
implemented as a circular buffer, with a storage capability of 30 errors. After
30 errors have been logged, the next error message overwrites the messages at
the beginning of the buffer.
If configured, the Switch sends internal error messages to syslogd by sending
UDP packet to port 514 on the syslogd machine. This allows the storage of
Switch errors on a syslogd capable machine and avoids the limitations of the
circular buffer.
syslogd provides system error support via a single log file and can notify a
system administrator in real time of error events. Additionally, the daemon
provides dial home capability.
