Syslog Collector

The goal of the Syslog Collector architecture designed by LUTEUS is to provide a scalable solution for handling huge quantities of Syslog messages and to help the administrator to classify, analyze and process them. The Syslog system provides the transport and storage mechanisms for event notification messages, in the form of Logs. Syslog is a de-facto standard defined by RFC3164 for logging system events. It was commonly and initially used by Unix systems (The unix syslog daemon syslogd), later on by network devices (router syslog, switch syslog, firewall syslog). It will be very efficient in a Cisco device architecture for the collection of PIX syslog and Cisco syslog generated by routers and switches)
