This document defines the '''official internal standard''' for Prometheus exporter port assignments within our infrastructure. The primary goal is to create a single, cohesive, and maintainable port scheme that prevents conflicts and is easy to understand and extend.
 
== Guiding Principles ==
* '''One List, One Standard''': This page is the single source of truth. All services that expose a Prometheus metrics endpoint '''must''' be included in this list with a unique port.
* '''Internal Consistency is Priority''': This list overrides external community standards or vendor defaults if they conflict with our internal, sequential scheme.
* '''Logical Grouping''': Ports are allocated in logical, contiguous blocks, making the scheme predictable and easy to manage.
* '''Documentation First''': Before deploying a new exporter, it '''must''' be added to this list with an assigned port.

Prometheus Exporter Port Allocation Standard

This document defines the official internal standard for Prometheus exporter port assignments within our infrastructure. The primary goal is to create a single, cohesive, and maintainable port scheme that prevents conflicts and is easy to understand and extend.

Guiding Principles

  • One List, One Standard: This page is the single source of truth. All services that expose a Prometheus metrics endpoint must be included in this list with a unique port.
  • Internal Consistency is Priority: This list overrides external community standards or vendor defaults if they conflict with our internal, sequential scheme.
  • Logical Grouping: Ports are allocated in logical, contiguous blocks, making the scheme predictable and easy to manage.
  • Documentation First: Before deploying a new exporter, it must be added to this list with an assigned port.
