Log-files

Log-files are used for the trouble shooting of system issues. Different information can be stored on different log files like a default system log file, a log file for cron tasks and also a log file for security messages.A daemon known as rsyslogd controls several log files and it acts as a replacement for sysklogd. It supports transportation through the protocols such as UDP or TCP. /var/log is the default location of log files in Linux.
