PromCon Online, a conference dedicated to the Prometheus monitoring system, features sessions highlighting significant developments and collaborations in the open-source community. Grafana Labs, which recently shifted its focus from Cortex to Grafana Mimir, a scalable long-term storage solution for Prometheus, has team members presenting on various topics. These include a joint session with Red Hat discussing the collaborative evolution of Cortex and Thanos projects, a review of recent enhancements to the Prometheus storage engine by Ganesh Vernekar, and insights into the future of Prometheus and its ecosystem by Richard Hartmann. The event underscores the collaborative spirit and continuous evolution of open-source projects within the cloud-native landscape.
