Syslog Overview

Developers of various operating systems, processes, and applications determine the circumstances that will generate system messages and write those specifications into their programs. Messages can be generated to give status, either at a certain period of time, or at some other interval, such as the invocation or exit of a program. Messages can also be generated due to a set of conditions being met. Typically, developers quantify these messages into one of several broad categories, generally consisting of the facility that generated them, along with an indication of the severity of the message. This allows system administrators to selectively filter the messages and be presented with the more important and time sensitive notifications quickly, while also having the ability to place status or informative messages in a file for later review.

Switches must be configured with rules for displaying and/or forwarding event messages generated by their applications. In addition, Syslog servers need to be configured with appropriate rules to collect messages so they can be stored for future reference. This document will describe how to complete these key configuration steps on S- K- and 7100-Series platforms.
