rsyslog

The rocket-fast system for log processing pipelines

Visit rsyslog

rsyslog is an open-source, high-performance engine for collecting, transforming and routing event data. It ingests from diverse sources (files, journals, syslog, Kafka), applies parsing, enrichment and filtering rules via RainerScript and modules like mmnormalize, buffers safely with disk-assisted queues, and forwards to Elasticsearch, Kafka, HTTP endpoints or files. It bridges classic syslog-style logging and modern data pipelines, with an AI-First (human-controlled) vision for observability.
