Chapter 7: Configuring logging

System logging is a method of collecting system messages generated by system events. The
Avaya G250/G350 Media Gateway includes a logging package that collects system messages
in several output types. Each of these types is called a sink. When the system generates a
logging message, the message can be sent to each sink that you have enabled.

System messages do not always indicate problems. Some messages are informational, while
others may help to diagnose problems with communications lines, internal hardware, and
system software.
By default, all sinks are disabled. When enabled, log file and Syslog sink settings can be saved
by using the copy running-config startup-config command to save the running
configuration to the startup configuration. However, the Session sink and its settings are deleted
when the session is terminated.
You can define filters for each sink to limit the types of messages the sink receives (see
Configuring logging filters
The logging facility logs configuration commands entered through the CLI or via SNMP, as well
as system traps and informative messages concerning the behavior of various processes.
However, a user enabling the log will only see entered commands with user-level no higher than
the user's privileges. For example, a user with read-only privileges will not see entered
commands having read-write user level. In addition, the log does not display entered
information of a confidential nature, such as passwords and VPN pre-shared-keys.
Description
Logging messages are sent to up to three configured servers, using
Syslog protocol as defined in RFC 3164. Messages sent to the Syslog
server are sent as UDP messages.
Logging data is saved in the flash memory. These compressed, cyclic files
serve as the system logging database.
Logging messages are sent to the terminal screen:
For a local connection - messages appear online on the local terminal.
●
For a remote Telnet/SSH connection - messages appear online on the
●
remote terminal.
This sink is deleted whenever a session ends.
