AxoSyslog: the syslog-ng™ fork built by its original developers. Get secure, supported, binary-compatible log management with advanced observability, daily vulnerability scans, and enterprise-ready features.

AxoSyslog, our syslog-ng™ fork, simplifies its licensing by adopting a single, clear open source license: GNU General Public License version 3 or later (GPL-3.0-or-later)

Learn how to monitor your syslog-ng™ or AxoSyslog deployment by exporting metrics into Prometheus using axosyslog-metrics-exporter. Boost observability and diagnose issues quickly.

Open source tools have been used to implement data collection to feed SIEM and other security systems for decades. We at Axoflow feel that these existing deployments of open source technologies play an important role in the future data supply chains as well.

Receive or send any kinds of OpenTelemetry logs, traces, and metrics with syslog-ng and AxoSyslog 4.3 using OTLP/gRPC

The starting point of our comprehensive syslog guide, that starts from the basics and covers every aspect of syslog collection, transport, and scaling

Learn how syslog works, including message format, severity levels, facilities, transport protocols (UDP, TCP, TLS), and reliability mechanisms like buffering and queuing.

Activity report of the first six months of AxoSyslog, the binary-compatible syslog-ng fork.

How to upgrade your syslog-ng installation to AxoSyslog in minutes, without any configuration changes

AxoSyslog 4.9 highlights: ClickHouse destination, gRPC improvements, new FilterX features, and bug fixes for the AxoSyslog and the syslog-ng projects.

Documentation updates for AxoSyslog, the cloud-native syslog-ng distribution: OpenTelemetry support, Splunk HEC destination, eBPF support, and new parsers

Republishing syslog-ng documentation in a new format, under the AxoSyslog Core name to comply with the syslog-ng Open Source Edition documentation license

Logs have been my passion for over two decades now. As a 3rd-year university student, I started an Open Source project to fix the “syslogd” problem. syslogd was the standard solution at that time to collect, deliver and aggregate system and device logs. The new project was named “syslog, the next generation” or syslog-ng for short. Well, 25 years on and we are now launching Axoflow – where we are bringing to market a long-overdue capability for the burgeoning Observability space that we anticipate will have similar impact!

Learn how syslog is used in practice across operating systems, network devices, applications, and security platforms. Explore common integrations with SIEMs and observability tools.

Learn how to install AxoSyslog, our syslog-ng™ fork from our repository on RPM-based Linux distributions like RHEL, Fedora, or AlmaLinux.
