Log Files and Syslog
Because of their importance, it is common practice to concentrate log files in one monitoring computer. Syslog is a system designed to allow devices to send their log files to a centralized server, known as a syslog server. Clients communicate to a syslog server using the syslog protocol. Syslog is commonly deployed and supports practically all computer platforms. The CyberOps Workstation VM generates operating system level log files and hands them over to syslog.
