New: Grafana Labs Launches Mimir 3.0, Expanding Open Observability at Scale at KubeCon + CloudNativeCon North America 2025Grafana Labs, the company behind the open observability cloud, today announced the launch of Grafana Mimir 3.0, the latest evolution of its open-source, horizontally scalable metrics backend. Introduced at KubeCon and CloudNativeCon North America 2025, Mimir 3.0 marks an architectural milestone, delivering new levels of reliability, performance, and cost efficiency for Prometheus-compatible monitoring at enterprise scale. Built on open source, open standards, and open ecosystems, Grafana Labs helps organizations innovate without lock-in and move fast without compromise. At KubeCon, the company also announced updates across its open-source ecosystem, including Grafana Tempo 2.9 with AI-assisted tracing, continued Kubernetes Monitoring enhancements, and deeper Prometheus and OpenTelemetry support to help teams simplify observability and gain more value from their data. "From open source and open standards to open ecosystems and open minds - building in the open is core to our philosophy at Grafana Labs," said Myrle Krantz, Senior Director of Engineering, Grafana Labs. "That's why we're continuing to invest in open source, like adding AI-assisted tracing in Tempo and making it easier to get the most out of OpenTelemetry and Prometheus. We're continuously improving Kubernetes Monitoring. And with the new Mimir 3.0 release, we're helping teams scale even more reliably, expanding what's possible for open observability in 2026 and beyond." Grafana Mimir 3.0: Improved Reliability and Performance Three years in development, Grafana Mimir 3.0 introduces a new decoupled architecture that separates the read and write paths for more reliable, large-scale metrics operations:
Together, these innovations make Mimir 3.0 the most resilient, high-performing, and cost-efficient metrics backend for Prometheus and OpenTelemetry data - now available on Grafana Cloud and for self-managed users via open source. Grafana Tempo 2.9: AI-Assisted Tracing and Faster Queries The latest release of Grafana Tempo, the open source distributed tracing backend, introduces new capabilities to speed up trace analysis and bring AI into the observability workflow.
Tempo 2.9 also deepens OpenTelemetry support by aligning with newer OpenTelemetry semantic conventions, reaffirming Grafana Labs' commitment to open, composable observability. Kubernetes Observability: Intelligent, Automated, and Built for Modern Workloads Building on the success of Grafana Cloud Kubernetes Monitoring, Grafana Labs has introduced powerful new capabilities that simplify observability across even the most complex Kubernetes environments. This is especially timely as a recent survey by the CNCF found that 80% of respondents work for IT organizations that have deployed Kubernetes in a production environment. Kubernetes Monitoring in Grafana Cloud has evolved into a best-in-class, opinionated observability solution that doesn't just visualize telemetry but interprets it, automates insights, and guides teams to action. New updates include:
At the recent ObservabilityCON event in London, Backbase systems engineer Andrei Drumov said of Kubernetes Monitoring, "We are collecting the telemetry signals using Grafana Alloy and we are using the Kubernetes Monitoring Helm charts developed and maintained by Grafana to manage the Grafana Alloy deployments. We chose this path because of its simplicity, flexibility, and modularity. It's relatively easy to manage. It allows us the flexibility to extend the configurations in case we need custom integrations, and it also allows us to conditionally enable or disable certain features based on certain customer needs, because some customers may need application availability, some other customers may need continuous profiling, some customers may need both. And with Kubernetes Monitoring Helm charts, it's really easy to juggle." Open Source Ecosystem Highlights According to Grafana Labs' 2025 Observability Survey, open standards like Prometheus and OpenTelemetry continue to gain momentum across the industry. The survey found that 71% of organizations use both OpenTelemetry and Prometheus, with more than half increasing their investments in OpenTelemetry for the second year in a row. While 67% of organizations use Prometheus in production in some capacity, OpenTelemetry is on a strong growth trajectory, with 38% of respondents investigating adoption and only 6% reporting no plans to use it at all. The findings also show that vendor neutrality and flexibility remain the most cited requirements for observability tools, directly aligning with Grafana Labs' open, composable approach. Building on these trends, Grafana Labs continues to invest in open standards and community-led innovation across its ecosystem:
