dedicated logging. If left blank, logging occurs (via the standard Linux
syslog facility) to /var/log/messages.
The Log level drop-down menu controls the level of detail present in
log messages, whether to syslog or to a dedicated log file. Not all of the
standard syslog logging levels are available. The menu offers a choice
(in order of decreasing detail) of:
•
Debugging information;
•
Informational messages;
•
Important notices; or
•
Warnings
The GCF input subsystem keeps its own audit log, independent from
the system log. The contents of this log are available using the “GCF
Audit Log viewer” facility as described in section 13.3.2 on page 182.
The amount of data retained is controlled by the Audit log size drop-
down menu, whose choices are:
•
64Kib (small);
•
256Kib (medium);
•
2MiB (large); and
•
16MiB (huge).
It is possible to copy all incoming data, verbatim, to a network port,
which can be specified in the Debug port text field. This is an
advanced debugging technique which is beyond the scope of this
manual.
In most configurations, all data from all inputs is sent to a single
multiplexor which then feeds all outputs, as described in section 1.3
on page 10. For more complex configurations, it is possible to
configure multiple multiplexers, each with their own set of input and
output services. In these situations, the GDI multiplexer drop-down
menu can be used to select a multiplexer instance with which to
associate this receiver. The menu offers a list of currently configured
multiplexers.
