UDP P ORT
The default port number is “514”, which should work for most installations. Consult your UNIX
documentation if you are unsure of the UDP port number.
D ECIMAL UNIX P RIORITY V ALUE
The default priority value is “38”, which should work for most installations. (Refer to Syslog Server
description, or consult your Server documentation if there are any problems). This value is
prepended to all messages sent to the Syslog Server; it is used by the Syslog Server to determine
how to handle the log message.
S YSLOG S ERVER
You may select to send reports to a Syslog Server rather than the local log. In the Call Detail
Recording Menu, System Message (DR) log Menu, and Authentication Message (DA) log Menu, add a
Syslog Server to the list of active servers to indicate that CRD and/or System and Authentication
Message reports should be sent to that server.
Note: You do not have to configure a Syslog Server name. The first Syslog Server configured will
be automatically named Syslog1, the second Syslog2, and so on. Up to ten Syslog Servers
can be configured. (For storing CDR reports, you can select up to three of these servers.)
L OG O PTIONS B ACKGROUND I NFORMATION
The Log Options feature expands the system’s log file capability and provides a consistent interface
to the device when working with logging or tracing the activity of a subsystem. Currently, the log
options feature supports
call detail recording (CDR), system message (DR) and authentication message
(DA) subsystems.
The log reports that allow you to trace the activity of a subsystem can be directed to a specific
location. The reports can be directed to a
local log file , or to a UNIX-style Syslog Server .
An off-node server can aid in the management of a site with multiple systems, since all systems can
send their log messages to a central log server. Note that in the case where multiple systems are
logging their reports to a single Syslog Server, the system name is used to distinguish which system
logged which report. This makes it crucial that each system be assigned a system name that is
unique within its environment.
L OCAL L OG F ILE O VERVIEW
The local log file is a circular file stored in RAM. It contains a fixed number of records. After the log
is full, each new record overwrites the oldest record in the file.
Note: The CDR local log is intended for diagnostic use and is not suitable for production use as
a CDR log.
S YSLOG S ERVER O VERVIEW
When you specify an offnode Syslog Server as the destination for log reports, you have more direct
control over:
•
the allocation of disk space
• the integrity of disk space (redundant, tape backup, UPS, etc.)
