AxoSyslog, our syslog-ng fork, moves to a single clear open source license: GPL-3.0-or-later. What changes for users and contributors.

Open source tools have fed SIEMs for decades. Why existing open source logging deployments remain key to the future observability data supply chain.

Monitor syslog-ng or AxoSyslog with Prometheus using axosyslog-metrics-exporter. Diagnose message drops and pipeline issues quickly.

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

A clear guide to how syslog works: message format, severity levels, facilities, UDP/TCP/TLS transport, and the mechanisms that prevent log loss.

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

After 25 years of syslog-ng, its creator launches Axoflow to bring a long-overdue data pipeline capability to the observability and security space.

AxoSyslog 4.9 adds ClickHouse as a destination: send logs directly to your self-hosted ClickHouse database for efficient storage and analysis.
