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.
Profile samples are collected periodically for each goroutine. If your program uses a large number of concurrent goroutines, make sure to check whether the overhead is within the acceptable range for your use case.
