🇫🇷 #VictoriaMetrics Meetup at @CriteoEng offices in Paris! Raphael Bizos - Site Reliability Engineer at Criteo presented: "A History of Automatic Aggregations" At Criteo, we’ve relied on automatic aggregations for years. “Automatic aggregation” is the name we give to a system of recording rules that matches most metrics and removes certain dimensions, such as the instance emitting the metric, to reduce the cardinality (i.e., the number of #metrics) and thus makes queries faster. What started as a workaround has become a key part of how we ensure backend stability and #reliability at scale, with hundreds of millions of active metrics, all without requiring users to write a single recording rule. It also significantly reduces the cost of metrics storage. Internally, we call this approach zero-effort #Observability, as most teams don’t have to write/maintain recording rules. In this talk, Raphael will explain how our approach to automatic aggregations has evolved over time and how we’ve adapted it to fit naturally into our Prometheus-based stack. He will share the different implementations we’ve tried, the lessons we’ve learned, and how our latest version takes advantage of recent improvements in Prometheus (new type label). A big thank you to everyone who joined us to exchange ideas and experiences about time series data and modern observability. #TimeSeries #Monitoring

Day 1 of #PromCon was amazing! 🚀 Lots of great talks, great people, and even better #observability stories. See you tomorrow. Drop by our table for swag and conversations about open source observability solutions! #prometheus #opensource #monitoring

Salut! #scala community in Paris 🇫🇷 We are happy to sponsor @ScalaIO_FR this year ☺️

At @criteo , we believe that #MCP will be key to empowering our clients and giving them the control to create and manage advertising campaigns in a new way. Check our latest tech article about "Lessons From Engineering Our MCP Server" 👇 #adtech medium.com/criteo-enginee…

In one week, @Criteo will participate in the first #PlatformConLive Paris 🇫🇷 Excited to sponsor this edition and have the opportunity to share our technical expertise with a talk by Gregory Boge & Baptiste RIQUIER 👏 Our team in place will be happy to chat with you at the booth❤️

Only one week left until our exciting #VictoriaMetrics #Meetup in Paris, hosted by @Criteoeng! 🇫🇷 📍 Location: Criteo HQ, Paris. 🗓 Date: October 15th 🕡 Time: 18:00 @dianavtodea – VictoriaMetrics Developer Advocate Talk: “Beyond Prometheus: pushing the boundaries of scalable #monitoring with VictoriaMetrics” Prometheus has become the go-to standard for metrics-based monitoring, but as environments grow in complexity and scale, teams often find themselves hitting its operational limits, especially around cardinality and long-term storage. This talk explores how VictoriaMetrics builds on Prometheus fundamentals to offer a more scalable and efficient alternative for teams managing high-ingestion workloads and demanding retention needs, without abandoning the familiar Prometheus ecosystem. @valyala - VictoriaMetrics co-founder, will present: “VictoriaLogs cluster architecture and typical use cases”. A single-node version of VictoriaLogs can handle hundreds of terabytes of logs. What if this isn't enough for you? Then the cluster version of VictoriaLogs comes to the rescue!

A year ago, we embarked on a mission to improve #DeveloperExperience by building an Internal Developer Platform using @BackstageDX. It started as a small initiative, but it quickly evolved, and adoption continues to rise👇 medium.com/criteo-enginee… #PlatformEngineering #IDP
