Syslog

Syslog is a standard protocol used for message logging in computer networks, allowing devices and applications to send event messages to a logging server. It provides a centralized way to collect, store, and analyze log data from various sources, such as servers, routers, and firewalls, facilitating troubleshooting, security monitoring, and compliance reporting.

Also known as: System Log, Syslog Protocol, RFC 5424, RFC 3164, Syslogd

Why learn Syslog?

Developers should learn Syslog when building or managing systems that require centralized logging, especially in network infrastructure, server administration, or security applications. It is essential for real-time monitoring, debugging distributed systems, and meeting regulatory requirements like PCI-DSS or HIPAA that mandate log retention and analysis.
