The V language is a domain-specific language for capturing the operational values of a host computer's resources and for checking their validity against user-defined rules.
V is nullipotent, declarative, and interpreted. V operates on objects which describe host resource variables and user-defined rules. Objects are dynamically typed and may belong to namespaces. V is extensible by design: its interpreter can discover and use third-party plugin modules.
V is well suited to helping system administrators with monitoring computer systems safely and without side effects.
