January 2026 Summaries

Polar Signals Cloud has updated its process for checking debuginfo status, making it easier for users to interpret memory addresses in flamegraphs that appear due to missing or unprocessed debug information. Users can now right-click on a frame within a flamegraph to access a sidebar that provides detailed debuginfo status, including the build ID, type, source, content hash, and timestamps for when the debuginfo was first and last seen, processed, and referenced. The debuginfo status can indicate whether it is awaiting upload, pending processing, successfully processed, or has encountered an error. Successful processing allows for human-readable function names to appear in profiles, while errors may require user intervention if they persist despite automatic retries. This streamlined approach aims to enhance user experience by simplifying the monitoring and interpretation of debuginfo in Polar Signals Cloud.

Sandwich View is an enhanced feature developed from the existing Caller/Callee tool, designed to provide a more intuitive understanding of profiling data by situating a selected function between its callers and callees within a flame graph. This view enables users to quickly ascertain the origins and effects of specific functions, answering pivotal questions such as what triggered a particular task and where the task's output is directed. By right-clicking on any frame in the flame graph or table and selecting "Show in Sandwich," users can delve deeper into profiling data, particularly useful for analyzing memory allocations in code. Sandwich View is available on Polar Signals Cloud, offering a 14-day free trial for new users to explore its capabilities and provide feedback via the Discord community.
