OpenMetrics: Is Prometheus unbound?

OpenMetrics aims to establish a standardized protocol for transmitting metric data, building upon the Prometheus exposition format to offer a more comprehensive solution for observability that includes logging events and correlating data. Although still in the draft stage and sandboxed by the Cloud Native Computing Foundation (CNCF), OpenMetrics seeks to eliminate hierarchical data models in favor of n-dimensional spaces through labels, thus promoting vendor-neutral guidelines and fostering greater cooperation among traditional networking, storage, and hardware vendors. The initiative introduces new features such as state sets, info metrics, and exemplars, while maintaining compatibility with Prometheus, which since version 2.5.0, supports OpenMetrics endpoints. Despite the support from major companies like Google and Uber, and its integration into projects like OpenTelemetry, the development of OpenMetrics faces challenges such as the need for better communication and tools to engage the community in its finalization process.
