Syslog is a standardized logging protocol used to collect, store, and analyze system messages from network devices, servers, and applications. It operates over UDP (default port 514) or TCP and enables centralized logging by forwarding messages to a Syslog server for monitoring and troubleshooting. Syslog messages are categorized by severity levels (0 – Emergency to 7 – Debugging) and facility codes to indicate the source of the log. Widely used in network management and security monitoring, Syslog helps administrators track system behavior, detect issues, and maintain compliance with logging policies.
