nsyslog

NSyslog is a modern, new generation, logagent and syslog server. It features a modular flow architecture of data collectors (inputs), processors and transporters.

Since all the codebase is written in NodeJS, it has a very small memory footprint and excels at data input/output. It also benefits from the excellent streams framework provided natively by node.

Main Features

• Small memory footprint
• Flow control of push and pull inputs
• On-Disk input data buffering
• A wide core catalog inputs, processors and transporters
• Extensible with custom inputs, processors and transporters
• Support for Apache Storm multilang protocol
• Multicore flows for parallel processing
