[apm][Help]transactionSampleRate set to low whether exception information will be missed

I wanted to optimize performance by setting the sampling rate, but I was worried that I would miss exception messages from the program

The errors are propagated even if they are unsampled, so you should see them all regardless, eg I sample at 1% for a trace that is always generating an error, I see 3 traces but 300 errors
