All of this runs through the colima MCP server in Claude Code. claude mcp add-json colima '{"command":"npx","args":["-y","kubernetes-mcp-server@latest"],"env":{"KUBECONFIG":"'${HOME}'/.kube/config"}}' I've allow listed `mcp__colima__*`. Local VM, fully isolated. 🤌

kubectl exec -n observability jaeger-all-in-one-<hash> -- wget -qO- localhost:16686/jaeger/api/services

For local development you don't need a dedicated MCP server for CockroachDB, Prometheus, or Jaeger. Just exec into the container and run commands directly. SQL in cockroach, wget the Prometheus HTTP API, same for Jaeger. 😏

🚀 Introducing the Polar Signals VS Code extension! See CPU time, memory allocations, and more as inline annotations, right next to your code. Works with Polar Signals Cloud and self-hosted Parca. polarsignals.com/blog/posts/202…

OCI image support coming to systemd. I'm getting strong rkt flashbacks. 🥲

Unfortunately, I won't be joining #FOSDEM. I got sick late last week and decided not to contribute to FOSDEM flu and canceled my trip. Have fun everyone! Next conference!

We cut cross-zone traffic for SLO monitoring by 90% using Prometheus subquery optimization. The trick: pre-aggregate data locally instead of shuffling 55M raw samples to Thanos queriers. Coming soon to Pyrra! 🚀 polarsignals.com/blog/posts/202…

We completed a major project to switch our storage file format from Parquet to Vortex 🌪️ resulting in 70% average query performance improvement across the board 🚀 Learn more about how rethinking interface-imposed limitations unlocked these gains in our latest blog post 👇

Previously, we've correlated GPU metrics with CPU profiles, now we can actually show you GPU time! This is suuuuuper exciting! 🚀

Pyrra v0.9 is here! 🎉 github.com/pyrra-dev/pyrr… It's incredible to see the amount of diverse contributions to the project! I didn't even realize it was that way until the release was published! Incredible to see! Thank you, everyone!

Native Histogram considered stable in @PrometheusIO going forward! 🥳 Props to all the people who worked on this for years!

This talk is rage baiting me hard. 😂 #PromCon

BER 🚄 MUC Oh my way to #PromCon! Excited to meet with the @PrometheusIO community again! See you tomorrow!

How do you achieve a 90% performance improvement in flame graph components? Attend the talk by Yomi Eluwande from @PolarSignalsIO to hear the story of their journey — from 67ms down to just 6ms! See you on March 24 & 26 at React Advanced Canada.

It's amazing to see a packed room for the talk of our very own @asubiotto, who is talking about Deterministic Simulation Testing @euro_rust right now! 🦀 ⌛

I wrote about why we should treat German string encoding/StringViews as Just Another Encoding™

Tame the OOM killer with OOMProf, the new eBPF memory profiler for Go programs being taken out by the kernels OOM killer! polarsignals.com/blog/posts/202…

🚀 Today, we're excited to launch Off-CPU profiling! Check out our blog on what we needed to do to make it most useful and how you can get started with it! 🧊 polarsignals.com/blog/posts/202…
