Tail-based sampling decides after the request completes. For finding latency outliers and errors, tail-based sampling is almost always what you want — and almost never what gets implemented. https://blog.turboawesome.win/2024/05/observability-at-scale-what-good-looks-like-when-you-have-too-much-data/ Wed, 29 May 2024 09:47:00 +0000 https://blog.turboawesome.win/2024/05/observability-at-scale-what-good-looks-like-when-you-have-too-much-data/ Observability problems at large scale are different from small-scale ones. Too little signal is replaced by too much signal, and the engineering challenge inverts. https://blog.turboawesome.win/2022/05/opentelemetry-in-go-distributed-tracing-that-doesnt-get-in-the-way/ Tue, 31 May 2022 10:14:00 +0000 https://blog.turboawesome.win/2022/05/opentelemetry-in-go-distributed-tracing-that-doesnt-get-in-the-way/ OpenTelemetry standardised distributed tracing across languages and vendors. Here's what idiomatic OTel integration looks like in Go — and the parts that aren't obvious from the documentation. https://blog.turboawesome.win/2020/02/context-propagation-in-go-deadlines-cancellation-and-tracing/ Wed, 19 Feb 2020 11:14:00 +0000 https://blog.turboawesome.win/2020/02/context-propagation-in-go-deadlines-cancellation-and-tracing/ Go's context package is one of the most important idioms in the language. Used well it enables clean cancellation and distributed tracing. Used poorly it becomes a magic bag of values that creates invisible dependencies.
