<command>rsyslogd</command> is special: it collects logs (internal system messages) that are sent to it by other programs. Each log entry is associated with a subsystem (e-mail, kernel, authentication, etc.) and a priority; <command>rsyslogd</command> processes these two pieces of information to decide on what to do. The log message may be recorded in various log files, and/or sent to an administration console. The details are defined in the <filename>/etc/rsyslog.conf</filename> configuration file (documented in the manual page of the same name provided in the <emphasis role="pkg">rsyslog-doc</emphasis> package).
