Tired of Node.js flamecharts full of `a`, `m`, and `_0x3f2`? We just shipped source maps support for Node.js profiles in Polar Signals Cloud.
Just add a plugin to your build pipeline, and your profiles show the real code.

Symbolization issues don’t have to be mysterious.
Polar Signals Cloud now shows exactly what’s happening with your debuginfo, right from the flamegraph frame: www.polarsignals.com/blog/posts/2...
📢 It’s a new year so we’re announcing something new which is the Sandwich view: A way to visualize a function’s callers and callees side by side for better debugging and performance work. Read more about it here: www.polarsignals.com/blog/posts/2...
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! 🚀
