What is NodeBrain?

NodeBrain is an interpreter of a declarative rule-based language designed for construction of state and event monitoring applications. It interacts with other monitoring components to perform simple element state monitoring or complex event correlation based on user specified rules. It is extended through the development of node modules (plug-ins) using NodeBrain's C API, and servants (programs written in any language) that interact with NodeBrain via stdin, stdout, and stderr. A small set of plug-ins are distributed with NodeBrain to provide commonly needed features such as peer-to-peer communication, log monitoring, event caching, and a web browser interface for administrators.

NodeBrain 0.7.4 Alpha Release with Tutorial (February 5, 2009)

NodeBrain 0.7.4 (Dunce) is available for alpha testing with an updated NodeBrain Tutorial. This version breaks compatibility with earlier versions by folding the prior concepts of "brains", "listeners", and "experts" into a single "node" concept. Rules created under 0.6.x and earlier versions will not work under 0.7.x without modification. Updates to the manual pages and other documents are expected within the next several weeks along with a beta 0.7.x release.
