This document contains the description of various metrics used in Refinery. It was automatically generated on 2024-09-27 at 16:19:55 UTC.
Note: This document does not include metrics defined in the dynsampler-go dependency, as those metrics are generated dynamically at runtime. As a result, certain metrics may be missing or incomplete in this document, but they will still be available during execution with their full names.
This table includes metrics with fully defined names.

This table includes metrics with partially defined names. Metrics in this table don't contain their expected prefixes. This is because the auto-generator is unable to resolve dynamically created metric names during the generation process.
