Syslogi

Syslogi is a cross-platform logging system designed to modernize traditional syslog practices. It provides centralized collection, filtering, correlation, and the inclusion of structured metadata alongside conventional messages. While it remains compatible with standard syslog, Syslogi emphasizes secure transport, reliability, and scalability for diverse environments.

Origin and scope: Syslogi builds on standard syslog concepts to meet cloud-native needs, multi-tenancy, and large-scale ingestion. It aims to interoperate with common syslog daemons and security information and event management tools while offering a richer data model.

Architecture and data model: Host agents forward events to collectors or brokers over encrypted channels. Messages are parsed into a structured schema with fields such as timestamp, host, facility, severity, app, and event_id, plus optional JSON payloads. It supports RFC 5424 and structured data formats.

Features: TLS transport, message authentication, and replay protection; high-availability collectors; multi-tenant isolation; flexible retention policies; enrichment pipelines; real-time search, dashboards, and alerting; and integrations with SIEMs and analytics platforms.

Usage and compatibility: Syslogi provides host-based agents and server-side collectors for Linux, Windows, and Unix-like systems. It preserves compatibility with standard syslog protocols and offers APIs and SDKs for developers. Deployments are possible on-premises or in the cloud.

Reception and governance: As an open-source project with a permissive license and community-driven governance, Syslogi has seen adoption in environments seeking scalable log collection and richer data for observability and security.
