  title: StatsD Admin Interface Configuration Gauges API
  version: 1.0.0
  description: OpenAPI projection of the StatsD admin/management interface. The native transport is a line-oriented plain-text protocol over TCP/8126 (default), not HTTP — but every supported command (`stats`, `counters`, `gauges`, `timers`, `delcounters`, `delgauges`, `deltimers`, `health [up|down]`, `config`, `quit`) is a self-contained request/response interaction with well-defined inputs and outputs and is therefore modeled here as a virtual `GET`/`POST` resource so that tools that consume OpenAPI (Spectral, MCP adapters, client generators) can reason about the surface.
