Write a bit about the logging challenge.
What is Rsyslog?¶
Rsyslog is a rocket-fast system for log processing. It offers high-performance, great security features and a modular design. While it started as a regular syslogd, rsyslog has evolved into a kind of swiss army knife of logging, being able to
- accept inputs from a wide variety of sources,
- transform them,
- and output the results to diverse destinations.
Rsyslog has a strong enterprise focus but also scales down to small systems.
