Log File Administration
Log files are stored in the

Working with the System Log Daemon The System Log Daemon (rsyslogd) is the traditional and most common logging daemon used on Linux systems. When this daemon is loaded upon system startup, it creates a socket (/dev/log) for other system processes to write to. It then reads any information written to this socket and saves the information in the appropriate log file according to entries in the /etc/rsyslog.conf file and any files within the /etc/rsyslog.d directory.
