UX Research Report - Prometheus and OTel's Resource Attributes

Explore a comprehensive UX research report examining how Prometheus handles OpenTelemetry (OTel) resource attributes through a 29-minute conference talk. Discover the current three strategies for managing OTel resource attributes in Prometheus, including mapping all attributes to labels (causing high cardinality issues), encoding attributes to target_info metrics with PromQL joins (creating barriers for users), and selectively promoting attributes to labels through configuration options (lacking flexibility for changes). Learn about the research methodology conducted through CNCF's LFX mentorship program, which employed both quantitative and qualitative approaches to gather insights from project co-founders, active and former maintainers, and end-users. Understand the findings regarding what works well in current implementations and identify areas for improvement, while gaining access to evidence-based recommendations for project maintainers on optimizing the handling of resource attributes in Prometheus environments.
