What problem does this solve?

The problem domain addressed by V is computer administration.

V provides a syntax and grammar for monitoring and reporting: it is well suited to monitor software configurations, application performance, and system vulnerabilities.

In practice, V is used in a manner similar to some scripting languages (like Bash and Perl), to solve problems with a well-defined set of inputs. It is not used as an application development language, and it is not typically well suited to solving problems with arbitrary user inputs.
