What are SysLog formats? How to use them?
Syslog is a standard for message logging that allows devices such as routers, switches, and servers to send event messages to a central log server. The messages sent by these devices are known as syslog messages and include information such as the date, time, device hostname, and message content. Syslog was originally developed as a part of the BSD operating system, but many other operating systems and network devices have since adopted it.
