SERVER REPAIR
One of the most effective ways to maintain stability and security on your server is by monitoring your log files. The log files named /var/log/messages, /varlog/secure and /var/log/syslog monitor general system information. Log files monitor for login attempts, e-mail transactions and many 3rd party applications. Code can be written to copy log files to a central computer or to send log files as email messages to the administrator. There are several 3rd party applications that can process and analyze your log files like Logcheck and Logsurfer.
Log file can be used to see newly installed software, the web browsing habits of the network users, and any major changes to the /etc/passwd file. The daily monitoring of log files is important to maintain stability and security on your server.
