If you're around at KubeCon EU and interested in CNCF @CortexMetrics, then come and join us for an informal Q & A meeting today (Thu 19 May) at 5pm in Tienda 4 (level 2 of the Solutions Showcase between the 2 exhibit halls)

@CortexMetrics v.1.10 is out ❤️ #cncf #cortex #kubernetes https://t.co/z69nX3o7l7

Cortex 1.10 now released! With experimental Exemplars, GA Alertmanager sharding and many new options to protect your cluster from overload. https://t.co/WKkkVbMdL1

Cortex is 5 years old today! The initial commit, which had a KV abstraction and some of the initial sharding code, is still in use to this day...

Great write-up about @CortexMetrics ingestion benchmarking!

Exciting news: today I join Grafana Labs as Distinguished Engineer for Grafana Cloud Backend, including Cortex, Loki and Tempo.

Catch this #GrafanaCONline session to learn how @RobinhoodApp's observability team scaled to 700M time series and beyond on @cortexmetrics using Grafana Enterprise Metrics.

We’ve just open sourced a Kubernetes operator for @cortexmetrics. If you are using Cortex, or thinking about it, take a look. We opened this very early so you can follow progress and contribute. https://t.co/9xC8RTFozJ

New on the blog: @tom_wilkie reveals the key to better scalability and more isolation (with no added costs!) in Cortex: shuffle sharding

Join @JacobLisi and myself to learn about @CortexMetrics , the massively scaleable multi-tenant Prometheus, tomorrow at 15:05 CET https://t.co/6QE5DIQwJW #KubeCon

Thanks to all the 100+ people who joined the Cortex office hour at KubeCon! It was great touching base with the community and answering your great questions! Don't miss the 2nd office hour on Thu at 11:15 CEST: https://t.co/pnTvXP7axT

🎉 Cortex 1.9.0-rc.0 has been cut! 🎉 Features 131 contributions by 28 authors. Thank you! Highlights: - Exciting features become stable like Shuffle-sharding - Query performance improvements! - Tons of bugfixes and optimisations! Go test it out! https://t.co/QjItH06ZVO

Thrilled to have accepted a position with @grafana on the Cortex team! Excited to be back at it with open source work, time series data, and fun distributed systems.

Cortex has just released versions 1.7.1 and 1.8.1 with a fix for local file disclosure vulnerability when using Cortex Alertmanager with enabled API (CVE-2021-31232). https://t.co/vEpBCgWBHO https://t.co/FHh9DmuTDh

🎉Cortex 1.8.0 has been released!🎉 It features 122 contributions by 35 authors. Thank you! Highlights: - Deletion of old blocks with per-tenant retention - Support for @ <timestamp> in PromQL - Per-tenant server-side encryption for S3 Go check it out! https://t.co/FW3VAw8Wqw

Cortex Community Meeting will take place later today, in 6 hours (15.30 UTC). Agenda and Zoom link available at

Very good question from @roidelapluie today on @fosdem: "What prevents @CortexMetrics & @ThanosMetrics merging?" TL;DR: Current state (not merged/sharing code) has its perks and both projects don't want to spend 6 months renaming variables 🤗🙃

We just released Cortex 1.7.0-rc.0, containing 86 contributions from 23 authors! Highlights: - Queries can now be federated across multiple tenants (experimental) - Introduction of a per-tenant bucket index for block storage Give it try :) https://t.co/I2d4oCqcBu

@burhan @grafana @PrometheusIO @bcamerongain @thenewstack @mattmendick I'd summarise the problems enterprises face with @Prometheus into broadly three categories: federation, scale & security. The federation arch for Prometheus is pretty out there for a lot of enterprises; this is why project like @ThanosMetrics and @CortexMetrics exist. 3/n
