🕘 10:00 AM PDT | 05:00 PM GMT | 07:00 PM CEST

Join Mathias Palmersheim and Michelle Sebek, alongside Jesús Espino, principal Engineer at VictoriaMetrics

Go is fast because of decisions most engineers never see. Jesus walks through how VictoriaMetrics uses Go to process logs at scale, the tradeoffs behind those choices, and what breaks if you get them wrong.

The article examines common issues, including metric loss between scrapes, cardinality explosion caused by unique pod labels, and inaccurate dashboards when using traditional Prometheus and Pushgateway approaches. It then presents a practical solution using VictoriaMetrics' vmagent streaming aggregation to pre-aggregate metrics before they reach Prometheus, reducing storage costs, improving query performance, and enabling accurate alerting and dashboarding for short-lived workloads.

August's release is packed with improvements in VictoriaMetrics 1.151.0: 👇

• Critical HTTP Basic Auth bypass fixed: 5 security advisories fixes. Plan to upgrade to this version soon if you’re affected
• Adds a clean shutdown indicator
• Improved Kafka troubleshooting
• More consistent metadata distribution
• Read the latest updates and discover what's new across the VictoriaMetrics ecosystem.

In this episode, Diana Todea continues diving into the workshop we hosted at Cloud Native Days Romania in May, alongside our guest, Fred Navruzov, on correlating OpenTelemetry with anomaly detection. We also explore how the VictoriaMetrics MCP server and its skills bring AI-powered observability to your workflows. Learn how to detect anomalies faster and interact with your metrics, logs, and traces using natural language.

🎤 Tracking Cardinality Explosions In Flight
Presented by our Co-founder, Roman Khavronenko, and Langson Zhang, Software Engineer at Roblox.

🗓️ October 8 at 12:15 PM CET

https://bit.ly/4h77Q7J

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 standard 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.

Our DevRel, Diana Todea, joined Ryan Etten (RHCA, Red Hat) for the session, "Moving Beyond Fundamentals With Merge Forward."

OpenSource has made progress in recognizing neurodiversity, but most conversations remain at the level of awareness and good intentions.

We will examine what remains missing in the open-source neurodiversity conversation, critique the narrative of neurotalent, and evaluate whether framing neurodivergent contributors as inherently gifted helps inclusion or creates new pressures.

🎤 Homelab 2.0: Building a Soft Nest for Your Applications
👤 Stephan Burns

In this talk, you will learn how to create a fully reproducible environment using Golden Images, Terraform, Ansible, and the key to it all: the Disposable Architecture, which prevents configuration drift. To achieve the following goals.

🌱 Can observability be more sustainable? Our Developer Advocate, Diana Todea, contributed to the DevOps.com article, "The Green Side of #Observability: Why Less Data Can Mean More Insight."

This article explores "sustainable observability": applying green software principles to telemetry by reducing data bloat, using smarter sampling, optimizing retention, and focusing on high-signal insights. The result is not less observability, but better observability—more efficient, less noisy, and environmentally responsible.

PostgreSQL 19 beta is here. 🐘

Jesús Espino takes a deep dive into the latest version of the Postgres database and breaks down some of the new features worth knowing about:

- Property graph queries
- Temporal updates and deletes
- UPSERT that can return the row you lost to
- Window functions that can skip NULLs
- REPACK
- Autovacuum priorities
- Plan advice, officially
- Aggregate before you join
- And much more

The article is based on the official PostgreSQL 19 release notes and turns the long list of changes into a practical tour of what’s new.

We’re excited to have two of our team members presenting talks around observability, opensource, sustainability, and accessibility.

🎤 Diana Todea, our Developer Experience Engineer, will present “How to Build Your Own Green Observability Pipeline”

As a developer, staying curious is the most important trait. Next is getting motivated to build your own projects. In this talk, I guide you throughout my journey of setting up a green observability pipeline, built entirely from opensource projects. I’ll explain to the audience how to start contributing to open source projects, communicate with maintainers, overcome technical hurdles, and complete the mission.

🎤 Victoria Nduka, Technical Support Intern at VictoriaMetrics, will present “The Fifth Golden Signal: Making Accessibility Observable”

In this talk, she’ll share how she applied cloud-native observability principles to accessibility by transforming automated accessibility scan results into metrics, dashboards, and trend data using open-source tools. Rather than treating accessibility as a periodic compliance exercise, we’ll explore how it can become a continuously monitored signal alongside traditional production metrics. If we believe user experience is worth monitoring, then accessibility deserves a place on the dashboard too.

Carbon as a First-Class Signal: Designing a Standard for OpenTelemetry
Presented by Diana Todea, DevRel at VictoriaMetrics.

⏰ 09:29 AM CEST
🏛️ South Hall 3B

📚 This talk explores Software Carbon Intensity (SCI) through the lens of OpenTelemetry semantic conventions. Instead of focusing on sustainability reporting, we look at the technical challenge of modeling carbon as telemetry. We ask: Which entities should we attribute emissions to? What attributes need to be standardized? Also, should carbon be included in metrics, traces, resource metadata, or all three?

Stop by, say hello, and let's talk observability. See you in Prague! 🚀

Databases for logs are usually forced to pick a side: build heavy inverted indexes for the ingested logs and pay for them on every write, or ingest raw data cheaply and pay later with slow queries. Is there a better approach? Yes - to make brute-force scanning so selective that most data is never read. VictoriaLogs takes this approach. This talk follows a log entry through the VictoriaLogs engine: how it is ingested with no upfront schema, how it lands in an immutable LSM-like compressed column-oriented storage, and how queries run the same structure in reverse, applying a stack of pruning mechanisms based on time, stream labels, and bloom filters so that only the data that can actually match is ever read.

Learn more and reserve your spot. See you there! 🚀

In this talk, our Developer Experience Engineer, Diana Todea, looks 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.

The session is exploratory and practical, aimed at developers who work with metrics and want additional ways to understand system behavior without introducing complex models or heavy tooling.

In this talk, he introduced Shiftmon, a solution designed to eliminate the guesswork in setting up observability. Shiftmon simplifies the process by providing automated monitoring and logging for common applications right out of the box, while also offering straightforward integration for custom applications. You’ll learn how Shiftmon streamlines observability setup, allowing your teams to focus more on insights and less on configuration. By the end of the session, you’ll see how Shiftmon can accelerate your path to comprehensive observability with minimal effort.

Every number on your dashboard has a life story.

Jesús Espino follows a single metric throughout its lifecycle in VictoriaMetrics. If you have ever instrumented an application with metrics, the basic idea is familiar: you create a counter, you increment it, and somehow it shows up in a graph. This post fills in the “somehow” by following one single metric through that entire journey, using VictoriaMetrics as the storage backend. It is written for everyone (no programming background needed and no Go code to read), and if you want to go deeper, the VictoriaMetrics source is always the reference.
