How to check your debuginfo status in Polar Signals Cloud A faster and easier way to troubleshoot debuginfo processing in Polar Signals Cloud.

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...

If you are using AWS S3 SDK for Rust on Graviton, you should enable the 'asm' feature on the sha2 lib transitive dep explicitly. Otherwise, it will not end up using hardware acceleration. Huge CPU drop for one of our services. Identified this issue using @polarsignals.com
