Not the GP, but: Imagine you're sampling successful traces at, say, 1%, but sending all error traces. If your error rate is low, maybe also 1%, your trace volume will be about 2% of your overall request volume. Then you push an update that introduces a bug and now all requests fail with an error, and all those traces get sampled. Your trace volume just increased 50x, and your infrastructure may not be prepared for that. |
