System Log Overview
Syslog is the system information center, to complete the unified processing and output of information.
The other modules in the system will send the output information to Syslog. Syslog determines the output format of the information according to the configuration of the user and outputs the information to the specified display device according to the information switching and filtering rules of each output direction configured by the user.
With the Syslog information producer, which is each module of output information, you do not need to export information to the console, Telnet terminal, or log host (Syslog server). You only need to output the information to Syslog. By configuring the appropriate filtering rules, information consumers, which are console, Telnet terminal, history buffer, log host and SNMP agent, a user can choose the desired information and discard unwanted information.
