上个月随公司 #VictoriaMetrics 在 #KubeCon 上分享了如何在 #OpenTelemetry 中实践 Retroactive Sampling(回溯采样)。本着能写就不要浪费的原则,把演讲内容整理成了博客。 相比尾部采样,它能节约 60% 内存,考虑到现在内(金)存(子)的天价,应该或多或少有点意义 :) jiekun.dev/posts/kubecon-eu-…

My talk last month at #CNCF #KCD Korea about Prometheus vs OpenTelemetry. The event setup was great with hardware far better than some flagship conferences. youtu.be/03bWKrIEzwI 上月在首尔的 Prometheus vs OTel 演讲,主办方布置非常用心。双语字幕在 B 站:b23.tv/BV192n66REJx

bilibili.com/video/BV1s3pv6w… #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😀

#VictoriaTraces now comes with a new built-in UI!
🚀 VictoriaTraces v0.12.0 is here! This release introduces a new built-in UI for exploring #traces. Find a trace, drill into its spans, and see what’s slowing down your application. VictoriaTraces is #OpenSource, so you can try it out yourself in the playground: play-vtraces.victoriametrics… 🔎 Check out the changelog for the full list of updates, including: 🔐 Security ✨ Features 🐛 Bug fixes docs.victoriametrics.com/vic… #Observability #VictoriaMetrics

Hallo, München! 🇩🇪 We're only 1 week away from @PromConIO 2026, the biggest conference for #Prometheus fans! 📍 Google Offices, Munich, Germany 🗓️ October 7–8 We’re looking 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 this talk: 🎤 Tracking Cardinality Explosions In Flight Presented by our Co-founder, @hagen1778, and Langson Zhang, Software Engineer at Roblox. 🗓️ October 8 at 12:15 PM CET hubs.li/Q04xbwlc0 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. 📌 Save your seat and come say hi in Munich. See you at #PromCon! 🎉 hubs.li/Q04xbwj80 #VictoriaMetrics #MonitoringSolutions #TechEvents #Prometheus

I seldom code with AI, but ask it to check source code when answering questions. I want AI to verify my answers, or when I don’t know where to start so ask for clues. Claude shows $1.5–3 for each Q. Probably the 1st time quantified the cost of answers.🫤

时至 2026 年了我还在用 M1 的 Macbook Pro,也是 AC 的最后几个月,想了很久要不要换,不过 Mac 已经涨价了,其次也没有什么卡顿,最后决定还是不换,立省几千块钱,打算把这台用到苹果配件断供(有人知道要多久吗?5 年?)。好在 VictoriaMetrics 编译起来很快,要是换个 Java 商城估计都换了几台了

不过可能另一个原因是手上有两台5900x / 7900x 的 12 核台式机,好像笔记本也没有太大的存在感。Ubuntu simply runs better than MacOS.

最近受困于血糖升高,可能是之前吃得不太控制,特别沮丧难过,改变饮食习惯的时候餐间还容易肚子饿。最沮丧的莫过于本来就已经减重并且长期呆在健身房了,还是得了这个毛病... 网友们一定要管住嘴多吃点健康的,少吃零食和加餐和饮料 QAQ 😭 已经焦虑到影响工作生活了

#KubeCon Day 1 in Yokohama. Haven’t had a chance to explore the city yet, and it’s almost time to head back. Looking forward to Reddit's talk tomorrow.

对 AI 生成的分析文档和建议文档感到很恶心,一个一句话能讲完的事情写成了: ✅问题背景 ✅原因分析 ✅代码比对 ✅修复建议 然后用的人还乐此不疲每个问题都按这样的格式来回复🤮现在看到这个绿色✅对钩就有种想直接 reject 的冲动 :(

I like seeing real-world comparisons of various tools we use. Most log stack comparisons read like vendor pitches, so it's nice to see one grounded in actual production workloads. This one runs Loki and VictoriaLogs side by side on 500 GB of logs over 7 days, on identical hardware. There are a handful of tools in this space, and Loki and VictoriaLogs are two of the more popular ones. The test results here are very interesting and I would like to try a similar comparison in my own environment. Harshit Luthra has put together a balanced comparison and outlines when each option is the right call, especially for label-heavy workloads and Grafana-native shops. Check it out! lckhd.eu/MchTXw #VictoriaLogs #Loki #Grafana

办信用卡的时候问我工作信息,答“软件工程师”。然后就紧接着这个问题,他问我工作用什么语言。我说:“Go 语言,Gee-Ooo,Go 语言。” 对方沉默了两秒然后说:“好的,这边记录好了”。 感谢对 DEI(Diversity, Equity, and Inclusion)的支持。🤔

很早就想录一期正经的 Q&A 采访。 3月跟团队去参加 KubeCon 前,在公众号上向中国用户征集了 #VictoriaMetrics 相关问题现场解答。 划重点:远程办公还招人吗?VM何时支持对象存储?与 ClickHouse 竞争有没有压力?降采样等付费功能下放吗? 期待上海 KubeCon 线下交流! youtu.be/_f0YLCTmCds
