About:
syslog-ng is a high-performance, open-source log management solution that collects, parses, and structures log data from diverse sources. It features a flexible configuration language and powerful correlation capabilities for transforming and enriching log events. The tool reliably forwards processed logs to various destinations including files, databases, and SIEM systems.
Key Features:
  • Advanced log parsing and filtering with a flexible configuration language
  • High-performance, multi-threaded architecture for high-throughput logging
  • Support for diverse sources and destinations (files, network, databases, Kafka)
  • TLS encryption and reliable message buffering for secure log transfer
Use Cases:
  • Centralized log collection from distributed servers and network devices
  • Pre-processing and normalization of logs before sending to a SIEM or analytics platform
  • Reliable log forwarding with buffering and encryption in enterprise environments
Alternatives:
  • rsyslog – Standard Linux syslog daemon; syslog-ng offers more powerful filtering and parsing capabilities.
  • Fluentd – CNCF project with extensive plugin ecosystem; syslog-ng is often considered lighter and faster for core syslog tasks.
