CNCF Ambassador & OpenTelemetry member

[Diana Todea @dianavtodea]

I'm really excited and honored to join the new batch of @CloudNativeFdn ambassadors. Thank you to all my community friends for the support and inspiration.

[Diana Todea @dianavtodea]

That's a wrap up for #DevOpsDays Istanbul, I had a blast. Check out my presentation slides at: https://t.co/XkYB6vu8fr

[VMblog @vmblog]

#Observability covers metrics, traces and logs. But carbon? Largely missing.

SCI can standardize the calculation. #OpenTelemetry can standardize the signal.

Together, carbon could become #telemetry engineers observe alongside the signals they already use.

What we make observable, we can make actionable.

Olá, Porto! Como estão?! 🇵🇹
#VictoriaMetrics is thrilled to be a Platinum Sponsor at @KCDPorto + #DevOps Days Portugal. 
📍 Super Bock Arena - Pavilhão Rosa Mota
📅 November 19-20
We look forward to connecting with the community, showcasing our latest innovations, and discussing everything from #metrics, #logs, and #traces to the latest in #OpenSource #observability.
And don’t miss these talks:

🎤 Tracking Cardinality Explosions In Flight

Presented by our Co-founder, @hagen1778, 
This talk is about estimating cardinality in flight, while the metrics are still streaming in. The estimator runs as a separate pipeline alongside the storage, not inside it. A small estimator maintains a HyperLogLog sketch for each label dimension and publishes the results as ordinary metrics in the Prometheus exposition format. It receives data over remote-write and is scraped like any other target.

🎤 Observing #Kubernetes Policies with Kyverno and VictoriaMetrics

Presented by our DevRel, @dianavtodea, and @TechTalkingMom

This talk presents a simple, technical workflow for observing Kubernetes policy behavior using Kyverno and VictoriaMetrics. Starting from a single validation policy, we show how policy evaluations and enforcement results are exposed as metrics, ingested into VictoriaMetrics and queried through a standard Prometheus-compatible API. A minimal dashboard is then used to inspect policy failures, affected namespaces and policy execution duration. The talk focuses on making policy enforcement observable using standard Kubernetes primitives and open metrics, without assuming prior experience with policy engines or observability systems.

VictoriaMetrics now has a new account just for the technical side. If you're interested in database techniques, observability, and products explained visually, give it a follow:

[VictoriaMetrics @VictoriaMetrics]

🌱 #Sustainability isn’t a one-off initiative. It’s an engineering mindset. 
It needs to become part of how engineering teams think, build, and operate. In this episode, we discuss why the real shift happens when we make sustainability part of the engineering culture.
Watch this short conversation today and discover how you can help expand its impact.

¡Enhorabuena, España! 🇪🇸🚀
VictoriaMetrics is heading to Torremolinos for @jotbconf 2026, and we're proud to be a Bronze Sponsor! 🥉
Our DevRel, @DianavTodea, will take the stage with her talk:
🎤 How to Defeat OTel’s Silent Killer: The Performance Overhead
Ever watched your pipeline silently eat up CPU and memory, without any obvious errors? That's the silent killer of #OpenTelemetry: performance overhead. Excessive instrumentation, unoptimized exporters, and high-cardinality data can lead to resource spikes, latency, and unexpected costs. We'll break down the sources of OpenTelemetry overhead, show how to measure and visualize its impact, and walk through practical techniques for reducing it. From sampling strategies to batching, from smarter exporters to #backend tuning, the audience will learn in a live demo how to keep the benefits of #OTel without burning your infrastructure budget. By the end, attendees will have concrete strategies to optimize their own observability pipelines for both performance and cost.

What if poisoned telemetry could trick an AIOps agent into deploying a back door?

Hei, Bergen! 🇳🇴
VictoriaMetrics is heading to Cloud Native Days Norway! 🚀
Join us for two technical talks exploring observability, cardinality estimation, and Kubernetes policy monitoring. Discover practical approaches and best practices you can put to work in your own environment.

🟣 Tracking Cardinality Explosions In Flight
🎤 @hagen1778 - Co-Founder
🕐 11:50 AM CEST 
https://t.co/MPkp4t9iHN
📍 Track 2: #Security, Governance, Observability & Testing 
This talk is about estimating cardinality in flight, while the metrics are still streaming in. The estimator runs as a separate pipeline alongside the storage, not inside it. A small estimator maintains a #HyperLogLog sketch for each label dimension and publishes the results as ordinary metrics in the #Prometheus exposition format. It receives data over remote-write and is scraped like any other target. There are no queries against storage, no new query language to learn, and nothing tied to a specific vendor, so any Prometheus-compatible setup can use it.
🟣 Observing Kubernetes Policies with Kyverno and VictoriaMetrics
🎤 @DianavTodea - DevRel
🕐 04:02 PM CEST
📍 Track 2: Security, Governance, Observability & Testing 
This talk presents a simple, technical workflow for observing #Kubernetes policy behavior using Kyverno and VictoriaMetrics. Starting from a single validation policy, we show how policy evaluations and enforcement results are exposed as metrics, ingested into VictoriaMetrics, and queried through a standard Prometheus-compatible #API.

#DevEx Talks episode 9 is here 🚀
In this episode, our DevRel, @DianavTodea, sat down with @SaiyamPathak, Head of Developer Relations at vCluster, and @theonlynabarun, Principal Software Engineer at Broadcom.
Cloud native systems need to be resilient by design, but resilience increasingly intersects with how efficiently we build and operate them. This session introduces CNCF TAG Operational Resilience, how it fits within the #CNCF community, and the work currently underway across these areas. We’ll explore current initiatives, highlight projects and ideas that have passed through Operational Resilience, and discuss how community members can get involved

Merhaba Türkiye! 🇹🇷
VictoriaMetrics is heading to @devopsdaysist! 🚀
Join our DevRel, Diana Todea, for her talk: “#Observability's Sixth Sense: Detecting Anomalies in Metrics”.
🕐 11:50 AM CEST 
📍 Dedeman Bostanci Hotel & Convention Center
https://t.co/gbsDOI7x09
In this talk, we look at anomaly detection as a complementary way of working with #metrics. Instead of relying on predefined limits, anomaly detection focuses on identifying behavior that deviates from what is normally observed over time.
Come meet the VictoriaMetrics team and discover new ways to level up your observability game.

#VictoriaMetrics 和 Roblox 的工程师在刚结束的 PromCon 上分享了如何“实时”检测高基数指标（而不是落盘后再扫描统计）。这个想法可能最早出现在小红书的博客，不过我们希望把它做成稍微通用的开源副产品 vmestimator，available now!
加了中文字幕希望对国内开发者友好些😀

[Diana Todea @dianavtodea]

Prague: 2 conferences, 1 week, great talks and networking. @CloudNativeFdn #Observability EU Summit and #OSSEUSummit 2026 are a wrap. See you next year in Vancouver and Glasgow!

[Aliaksandr Valialkin @valyala]

Great talk at PromCon EU 2026 from @hagen1778 and Langson Zhang about real-time estimation of the number of unique time series at a very large scale in Roblox (billions of unique time series ingested at hundreds millions of samples per second)!

Thanks to @maksim_ka2 for creating the vmestimator!
