Rsyslog is a rocket-fast system for log processing.
It offers high-performance, advanced security features, and a modular design. Originally a regular syslogd, rsyslog has evolved into a highly versatile logging solution capable of ingesting data from numerous sources, transforming it, and outputting it to a wide variety of destinations.
Rsyslog can deliver over one million messages per second to local destinations under minimal processing (based on v7, Dec 2013). Even with complex routing and remote forwarding, performance remains excellent.

Getting Help (Other Sources)Rsyslog is available in the package repositories of most Linux distributions. On non-systemd systems (e.g., Ubuntu), rsyslog is often pre-installed.
Project-Provided Packages (for latest versions)Distributions often lag behind in packaging the latest rsyslog releases. Official builds for newer versions are available here:
See: Build Instructions
Build Environment Requirementspkg-config
libestr
liblogging
(stdlog component, for testbench)Build support libraries from source if you're working with the latest git master.
OS-specific Build InstructionsRefer to the respective section in the original README for required packages on CentOS, Ubuntu, Debian, SUSE, etc.
Development Containers & TestingReady-to-use build environments are provided in packaging/docker/dev_env
. These images were previously built in the separate rsyslog-docker repository and are now maintained here. See packaging/docker/README.md
for details. Runtime container definitions are in packaging/docker/rsyslog
. Run the test suite inside the container with make check
(limit to -j4
).
