Log analysis and system monitoring with nfer
Sean Kauffman · Science of Computer Programming · 2022
Nfer is a tool that implements the eponymous language for log analysis and monitoring. Users write rules to calculate new information from an event stream such as a program log either offline or online. In addition to a command-line program, nfer exposes interfaces in Python and R and can generate monitors for embedded systems. Nfer is designed to be fast and has been repeatedly demonstrated to outperform similar tools.
