Prometheus 3.0 has introduced enhancements to facilitate better integration with OpenTelemetry, addressing challenges such as resource attribute handling, UTF-8 support, and differing data collection models. Prometheus users can now promote OpenTelemetry resource attributes to metric labels, which helps in maintaining data clarity without overwhelming the system's performance. The new PromQL function, info, simplifies querying by mitigating conflicts from changing resource attributes. Additionally, Prometheus 3.0 supports the OpenTelemetry protocol (OTLP) endpoint for stable data ingestion, offering improvements in translation efficiency and resource management. The release also includes UTF-8 support, aligning Prometheus with OpenTelemetry standards and accommodating diverse character inputs. While delta temporality is not yet fully supported, efforts are underway to enable this feature, reflecting a broader commitment to making Prometheus a robust backend for OpenTelemetry metrics. The blog encourages community participation in further development and provides resources for users seeking more information or wishing to contribute to the ongoing improvements.
