About:
rsyslog is a high-performance log processing infrastructure that collects, filters, and forwards log messages from multiple sources. It supports TCP, TLS, and RELP protocols for reliable log transport, and can handle millions of messages per second. The tool offers advanced features like regex filtering, modular architecture, and flexible output formats for enterprise-grade logging solutions.
Key Features:
  • High-performance multi-threaded architecture
  • Reliable transport via TCP/TLS/RELP protocols
  • Advanced message filtering and parsing
  • Modular plugin system for extensibility
  • Support for major database and cloud backends
Use Cases:
  • Centralized log aggregation for server fleets
  • Compliance and audit log management
  • Real-time log analysis and alerting
  • High-volume syslog processing
Alternatives:
  • syslog-ng – Similar functionality with different configuration syntax; rsyslog generally offers better performance for high-volume scenarios
  • vector – Modern alternative with better observability features, but rsyslog has broader legacy syslog compatibility
