10.1.1 Syslog Messages
All major events on X4000 ’s various subsystems (
➤➤
ISDN ,
➤➤
PPP ,
➤➤
CAPI , etc.) are logged in the form of syslog messages (system logging
messages).
The number of details visible depends on the level set (eight steps from critical
and information to debug). The logged data are saved by X4000 in a list of
adjustable length. All information can be and should be passed to one or more
external computers for saving and further processing, e.g. to the system
administrator’s computer. The syslog messages are lost when you restart
X4000 .
Avoid forwarding syslog messages to log hosts reached over a dialup
connection. This raises your telephone bill unnecessarily.
