@openvalue.eu Hackathon Day 3. I compared Opus and Sonnet using @grafana.bsky.social gcx to diagnose the OpenTelemetry demo. Both pinpoint the root cause correctly. And I wrote a short reflection after 3 days working on AI and how to apply that on Observability. ceesbos.nl/posts/observ...

2nd hackathon day with @openvalue.eu I tested gcx from @grafana.bsky.social with claude. It works very well (with some follow up questions) really impressive! I learned: Claude code exports OTEL data, that gives really useful insights!! And a nice team outing 😀 goto.ceesbos.nl/hack2026d2

The yearly hackathon with @openvalue.eu! 33 degrees Celcius inside the building is pretty challenging ... Today started with a 'AI-accelerated development' training by @tomwigleven.bsky.social. After that I started exploring the new @grafana.bsky.social 'gcx' cli tool. goto.ceesbos.nl/hack2026d1

What actually happened? What was the root cause? 😟 🕵️I tempt to opt for the 'hard path' and conduct a thorough investigation, especially in unusual cases with significant impact. I tend to dig as long as I can to find the actual cause and by doing so I already found quite some nasty problems ☺️ 🧵

Our OpenValue Wrapped 2025 is here! How many cups of coffee? How many AI pair programming sessions? And did we deploy on Fridays? Watch the GIF to find out👉 #OpenValueWrapped #BetterSoftwareFaster

🚀 New challenge alert! Can you spot performance issues when using virtual threads? Observability Code Challenge 2 compares regular threads vs virtual threads in Java 21 & 25 using OpenTelemetry and Grafana. 👉 goto.ceesbos.nl/ghch02 #Java #Observability #VirtualThreads #OpenTelemetry #AOCC

Today I had the honor to speak at @devoxx.com about "How I solved production issues with OpenTelemetry (and how you can too)" 📷 Photos taken by Dimitris Doutsiopoulos & @johanhutting.bsky.social In case you missed it: slides, code examples and more is available goto.ceesbos.nl/devoxx2025

Just prepared the last pieces for my presentation at @devoxx.com I am ready for it, so let's go #devoxx

Next week #Devoxx Belgium! I am preparing my talk for next week at the moment. Are you joining as well? Hope to see you there @devoxx.com! m.devoxx.com/events/dvbe2...

Today I am preparing for #JCON Within two weeks I will be presenting how #OpenTelemetry can help you with your observability challenges. I am looking forward to the conference! @jcon.one

Really nice article: thenewstack.io/observabilit... by @martindotnet.bsky.social This is exactly how I see this as well. Observability is very much an 'every engineer's job'!

Observability: Every Engineer’s Job, Not Just Ops’ Problem

Observability is more about software engineering than it is about operations.

📣 Application Observability Code Challenges are coming soon! Goal: develop an observability mindset and practice with your observability tools. https://goto.ceesbos.nl/aocc The first challenge is being prepared! Stay tuned! #AOCC #OpenTelemetry

🎉 Wicked! #GrafanaCON 2025 is headed to Seattle (Emerald City) from May 6-8! As a bonus, we’ve added a full day of workshops on May 6. We had hundreds of people on our waitlist last time, so sign up to receive notifications tickets go on sale: grafana.com/events/grafa...

#GrafanaCON 2025 has been announced by @grafana.bsky.social 📣 This reminds me of my own talk back in April, it was a great honour to speak at GrafanaCON 2024 see https://goto.ceesbos.nl/gc24 I am looking for to this event in 2025! See https://grafana.com/events/grafanacon/ Maybe on stage again??

🎉 Introducing the #OpenTelemetry Report. This new report presents insights around #OTel's rapid growth, central value, instrumentation, community engagement, and developer traction. Take a look (no form required!): https://grafana.com/opentelemetry-report See a few charts and findings in 🧵.

I learned more about Spring Modulith and OpenTelemetry at the @openvalue.eu Utrecht meetup today. Thanks 🙏 @ceesbos.nl and Jos Roseboom and the organisers.

Amazed by the detective skills of @ceesbos.nl shown in his observability talk #opentelemetry

Second talk at the @OpenValue.eu Utrecht meetup: @ceesbos.nl talking about solving issues with OpenTelemetry 👌🏻

❓ Do you recognise this❓ Just before a demo, update to the latest version, start the new version and 💥 But that is the good thing about #observability and #OpenTelemetry, you can find 🔍 the problem and fix it 😅 This is why I love #observability: it helps to fix problems faster 🏎️

Does your observability practice incorporate #Prometheus? #OTel? Both? Let us know in the 2025 Observability Survey. It only takes 5 minutes and you could win a #Grafana swag pack! https://grafana.com/observability-survey/?mdm=social&src=ma&camp=obs-survey-2025

If you have lots of new and active users like @bsky.app, I can imagine that the systems are having tough times and upscaling is needed. I'm curious about how the monitoring dashboards look like these days. 📈 Nice to see the stats at: bsky.jazco.dev/stats @jaz.bsky.social thanks! #observability
