The default channels are shown as follows:
• default_syslog
Sends messages to the daemon facility at severity info and higher.
(info is a predefined severity level that allows messages of its
severity level or higher to be logged to the channel.)
• default_debug
Sends messages tot he file named.run and tracks the daemon’s
current dynamic debug level.
• default_stderr
Sends messages of severity info and higher to standard error.
• null
Discards everything it receives.
Message Categories There is a large collection of message categories
listed in Table 3-1. A list of channels can be assigned to each message
category; messages from that category will then be sent to every channel
in the list.
The default category is a catchall used for unclassified messages and for
categories that do not have a channel list explicitly defined. Categories
are listed in Table 3-1.
