If you don't see any profiling data in sentry.io, you can try the following:
- Ensure that performance monitoring is enabled.
- Ensure that the automatic instrumentation is sending performance data to Sentry by going to the Performance page in sentry.io.
- If the automatic instrumentation is not sending performance data, try using custom instrumentation.
- Enable debug mode in the SDK and check the logs.
Profiles for multi-threaded servers like puma might not capture frames correctly when async I/O is happening. This is a limitation of stackprof.
